1. Safety ■ Safe Operation The following safety information is vitally important for safe operation of the AB50J. Failure to follow these instructions can result in personal injury or DEATH. ❑ Pre-Start Inspection At the start of each work shift, the AB50J shall be given a visual inspection and function test. See the “Daily Inspection and Maintenance” chapter 7, in this manual for a list of items to inspect and test.
1. Safety ❑ Electrocution The AB50J is an all metal boom, NON-INSULATED, aerial work platform. DO NOT operate it near ELECTRICAL conductors. Regard all conductors as being energized. DO NOT operate outside during a thunderstorm. ❑ Tipover and Falling Hazards DO NOT operate the AB50J from a position on trucks, trailers, railway cars, floating vessels, scaffolds, or similar equipment unless the application is approved in writing by Snorkel.
1. Safety ❑ Mounting and Dismounting Precautions ❑ Fuel Handling Precautions Use three points of support when getting on or off the platform (two hands and one foot or a similar set of points). Keep the platform clean. DO NOT smoke or permit open flames while fueling or near fueling operations. DO NOT jump off the machine. DO NOT dismount while the machine is in motion. ❑ Starting and Stopping Precautions DO NOT start until all personnel are clearly away from the machine.

2. Safety Devices ■ Safety Device Information For emergency operation controls and procedures, see the “Emergency Operation” chapter 9. The devices listed in this chapter are safety devices. They are on the AB50J to increase safety in the work place for both the operator and other people near the AB50J. CAUTION DO NOT by pass, disable, modify, or ignore any of these devices.
2. Safety Devices ❑ Engine Shut-Off Alarm ❑ Axle Unlocked Alarm The engine shut-off alarm comes on when the engine is overheating or the oil pressure is low. The front axle of the AB50J pivots so that all four wheels remain on the ground when the machine is driven with the main boom elevated less than 5° and the riser booms down. This improves traction for 4-wheel drive machines and reduces the ground pressure for all machines while they are driven between work sites.
2. Safety Devices ❑ Tilt Alarm ■ Other Safety Devices The tilt alarm warns the AB50J operator that the AB50J is over 5° out of level. If the tilt continues to increase, the AB50J will eventually tip over. ❑ Battery DANGER To prevent Death or Serious Injury, when you hear the loud two toned (high-low-high-low...) alarm, immediately retract and lower the platform. When the platform is completely down, determine and correct the cause of the tilt before raising the platform again.
2. Safety Devices ❑ Emergency Stop Switches ❑ At Platform Control Box ❑ At Ground Control Box Press the large red Emergency Stop switch down (off) and the entire machine stops, the engine turns off, the brakes automatically set, and nothing moves. This switch must be pulled to its up (on) position to control the AB50J from the platform.
2. Safety Devices ❑ Foam Filled Tires ❑ Lanyard Anchor Points Optional foam filled tires eliminate the possibility of air leaks or blowouts which might cause a tipover. Foam filled tires are therefore a safety device. Inspect them at the start of each work shift according to the procedures in the “Daily Inspection and Maintenance” chapter 7. The foam filled tire shown here, shows signs of damage and therefore is not acceptable for service.
2. Safety Devices ❑ Ground Fault Circuit Interrupt ❑ Platform Gravity Gate The ground fault circuit interrupt (GFCI) is located near the platform control box. The GFCI protects against short circuits to ground. When there is a short to ground the GFCI shuts off power to the electrical outlets. To use the outlet, connect the power input connector, at the rear of the turntable, to a source of 125 V AC, 15 A electrical power.
2. Safety Devices ❑ Ground Operation Switch ❑ Level Sensor The level sensor, located behind the ground control box, detects how far out of level the turntable is. If the turntable gets over 5° out of level and the booms are raised, the level sensor activates the tilt alarm. The Ground Operation switch prevents the platform from moving if something accidentally pushes one of the platform moving switches at the ground control box.
2. Safety Devices ❑ Platform Work Lights ❑ Tipover Hazard Light This light will come on when the front axle should be locked but is not. The axle unlocked alarm will sound when this light is on. When this light comes on you should immediately completely lower the booms. The optional platform work lights are located on top the platform guardrail.

4. Gauges ■ Ammeter ■ Engine Oil ❑ Gas Engine The ammeter gauge shows the electric current from the alternator to the battery. When the engine is running, the needle in the ammeter gauge should not be to the left of “0.” Under normal operating conditions, after the engine has been running for a few minutes, this gauge should read “0.” ❑ Diesel Engine ■ Engine Coolant Engine oil level is measured with a dipstick. Oil capacities given in “Specifications” chapter 3,are approximate.
4. Gauges ❑ Engine Oil Dipstick Gasoline engine ❑ Filter Minder Indicators Diesel engine As the filter clogs, the vacuum increases (pressure drops). As the vacuum increases, the yellow indicator (1) raises toward the red area (2) of the sight glass. When the yellow indicator reaches the red, it’s time to change the air filter. Engine oil level should always be between the lines on the dipstick, never above or below them. The AB50J should be on level ground when you check the dipstick.

4. Gauges ■ Hydraulic Oil Level ■ Hydraulic Oil Temperature The hydraulic oil level gauge (1) is on the side of the hydraulic oil tank (2). The hydraulic oil temperature gauge measures the temperature of the oil in the tank. The temperature should not exceed 200°F (93°C). If it does, reduce your driving speed or stop the engine and let the hydraulic oil cool. ■ Temperature The gauge shows the actual level of oil inside the hydraulic oil tank.
5. Automatic Shut-Offs and Circuit Breakers ■ Automatic Shut-Offs ❑ Engine Oil Pressure The AB50J engine will automatically shut off if: 1. The engine temperature gets too high. 2. The engine oil pressure gets too low. 3. The main circuit breaker trips. A continuous tone alarm will sound as the engine begins to overheat or if the oil pressure is low. For circuit breaker problems there is no audible alarm. The subsections below explain the shut-offs in more detail.
5. Automatic Shut-Offs and Circuit Breakers CAUTION If the cause of the problem is not immediately obvious, refer the problem to a qualified service technician. There are two ways to get to the oil filter on a Kubota engine. 1. One way is to rotate the turntable (4) about 30° clockwise with respect to the chassis (5) then reach through the hole (6) in the bottom of the turntable (4). CAUTION Use caution to avoid burns as the engine and exhaust manifold might be hot.
6. Controls ■ Controls Description “Operation” chapter 8, covers the proper use of controls. This chapter shows the controls at the ground control box and the platform control box, and explains what each control does. See the “Emergency Operation” chapter 9, for correct emergency operation procedures. See the “Options” chapter 11, for correct operation procedures of any optional equipment.
6. Controls ■ Ground Control Box Controls for operating the AB50J from the ground, are located on the left side of the turntable. The number of each control below corresponds to the control’s call out on the control box illustration. 1. Emergency Stop: Press the red button in, at any time, under any conditions, and the entire machine stops - the engine turns off, the brakes automatically set, and nothing moves. This switch must be out for anything on the machine to work. 2.

The further forward you push the controller the faster the AB50J goes (max. 3.5 mph, 5.6 km/hr). ● STEER RIGHT: Slowly push the Drive/Steer controller to the right and the front wheels move in the direction for a right hand turn.
6. Controls There are blue and yellow arrows on top of the chassis. The blue arrows point to the FORWARD end of the chassis and to the LEFT side of the chassis. The yellow arrows point to the REVERSE end of the chassis and to the RIGHT side of the chassis. ■ Battery Switch The Drive/Steer controller is color coded to match the arrows. The color coding is designed to keep you from becoming disoriented when you are aloft and the platform is rotated with respect to the chassis.
7. Daily Inspection and Maintenance At the start of each work day (or 8 hour shift), an AB50J qualified operator must perform the Daily Inspection and Maintenance as listed in the table below. Defective parts and/or equipment malfunctions jeopardize the safety of the operator and other personnel, and can cause damage to the machine. DANGER The purpose of the Daily Inspection and Maintenance is to keep the AB50J in proper working condition and to detect signs of malfunction at the earliest possible time.
7. Daily Inspection and Maintenance The rest of this chapter shows how to perform the inspection and maintenance required for each item in the Daily Inspection and Maintenance Table. ■ Engine Fuel Level 3. Open the strap (4). 4. Manually lift the tank out. ■ Fuel Tank Cap Visually check to see that the gasoline or diesel tank is full. See the “Specifications” chapter 3, fuel for octane and grade. Check to see that the tank cap is in place and is tight.
7. Daily Inspection and Maintenance ❑ Diesel Engine ❑ Diesel Engine Keep the oil level between the marks on the engine oil dipstick. Visually inspect the entire length of the fuel line, from the engine to the fuel tank, for leaks. The distance between the top and bottom dipstick marks corresponds to about 1 qt USA (one liter). Add oil, if needed, at the top of the engine. ■ Engine Coolant Level See the “Specifications” chapter 3, for the correct engine oil grade and weight.
7. Daily Inspection and Maintenance ■ Wiring Harnesses ■ Battery Terminals Battery terminals should be clean and free of dirt and corrosion. If the machine is equipped with the optional extra battery, check it too. Inspect all the wiring harnesses, on the machine, for loose connections, broken wires, and frayed insulation.
7. Daily Inspection and Maintenance ■ Battery Fluid Level DANGER The hydraulic oil level should be between the two marks (2) and (3) on the sight glass gauge. Batteries emit hydrogen and oxygen, elements that can combine explosively. DO NOT smoke or permit open flames or sparks when checking batteries. If necessary, add hydraulic oil at the filler cap. See the “Specifications” chapter 3, for type and grade of hydraulic oil.
7. Daily Inspection and Maintenance ■ Tires ■ Bolts and Fasteners DANGER Visually inspect all fasteners to see that none is missing or obviously loose. Death or Serious Injury can result if an AB50J tips over. An air filled tire that has an air leak or blow out is a tipover hazard. DO NOT raise the AB50J platform if any tire has an air leak or is in such condition that a blow out could occur. Pay particular attention to all of the pin caps (1) and snap rings (2) that connect the booms.
7. Daily Inspection and Maintenance ■ Structural Damage and Welds Visually inspect all welds for cracks, all structural members for deformity, and all sheet metal for dents that could interfere with machine operation. Pay particular attention to all of the upper rotation bearing bolts. None should be visibly loose, missing, or have broken heads. Pay particular attention to all of the lower (view from under the machine) rotation bearing bolts. None should be visibly loose, missing, or have broken heads.
7. Daily Inspection and Maintenance ■ Lanyard Anchor Points ■ Swinging Gate Visually check the lanyard anchor points to see that they are not deformed or cut off. ■ Platform Gravity Gate Inspect the optional platform swinging gate, at the platform entrance, to see that it swings freely, latches securely, and is not deformed in any way. ■ Platform Guardrails Inspect the platform gate to be sure it is present and moves freely.
7. Daily Inspection and Maintenance ■ Flashing Lights ■ Charging System Visually check the optional flashing lights, to see that the lights flash at approximately one flash per second when the engine is running. With the engine running at Ground Operation IDLE, the needle in the ammeter gauge should not be to the left of “0” (left of “0” is discharging). ■ Air Filter Start the engine from the ground control box. Leave the engine running for the next step.
7. Daily Inspection and Maintenance Check both positions of each switch. For correct operating procedures see the “Operation” chapter 8. Pay particular attention to the Emergency Stop switch (4) to see that it turns the AB50J engine off when struck. ■ Emergency Power DANGER When you check turntable Swing at CCW (1) the turntable will move directly toward you. Be sure you have room to step backward. Listen for the start up alarm when the Master Key Switch (5) is first turned ON.
7. Daily Inspection and Maintenance ■ Platform Box Switches and Alarms ■ Ground Fault Circuit Interrupt Check all of the platform moving, drive, and steering functions from the platform control box to see that they cause the AB50J to move the way it should. For correct operating procedures see the “Operation” chapter 8. Pay particular attention to the Emergency Stop switch to see that it turns the AB50J engine off when struck.
7. Daily Inspection and Maintenance ■ Platform Work Lights Look at the surface that slides on each slide pad. The paint should still be in place and there should not be any signs of bare metal gouging. To check the optional platform work lights, while the engine is running, momentarily turn each work light on (use the switch on the back of each light) to see that they both work. ■ Slide Pads Check the slide pads and paint inside the front end of the base boom similarly.
7. Daily Inspection and Maintenance ■ Axle Unlocked Alarm To test the Axle Unlocked Alarm and Tipover Hazard light do the following: 1. Start the engine from the ground control box and stow the AB50J. 1 DANGER If either the Axle Unlocked Alarm or Tipover Hazard light fails to respond correctly, repeat this test. If either fails a second time, remove the AB50J from service IMMEDIATELY and refer the problem to a qualified service technician. 2 2.
7. Daily Inspection and Maintenance ■ Placards and Decals Look to see that all placards and decals are in place and legible. Replace any missing or illegible placards or decals before placing the Snorkelift into service for the daily work shift. Decal and placard kits for the AB50J are available from Snorkel dealers.

8. Operation ■ Operating Procedures ■ Emergency Stopping This chapter explains how to properly start and operate an AB50J that has either a gasoline or diesel engine. Starting a gasoline engine that is set up to burn LPG only or dual fuel, is also explained in this chapter. Read and understand all the previous chapters in this manual before you begin to operate an AB50J. To stop an AB50J, push the Emergency Stop button at the ground control box or at the platform control box IN.
8. Operation ■ Operation Considerations To use this chapter, first decide whether you will be starting and operating the AB50J from the ground control box or the platform control box. Begin at the section entitled “Starting From Ground Control Box”, if you intend to start and run the AB50J from the ground station. Begin at the section entitled “Starting From Platform Control Box”, if you intend to start and run the AB50J from the platform.
8. Operation 9. Turn the key (10) to ON and pause there a few seconds (but not over 30 seconds), while an alarm sounds to alert others that the AB50J is about to start. 10. For a diesel engine: If engine is at cold ambient temperature, hold the Choke/Cold Start switch (12) up for 10 seconds just before you perform the next step. Gasoline engines have automatic chokes. They do not use the Choke/Cold Start switch. 6.
8. Operation ■ Starting From Platform Control Box Before you begin to operate the AB50J from the platform control box, a qualified operator must perform the “Daily Inspection and Maintenance” as described in chapter 7. 4. Insert the key (4) and set the Master Key Switch (5) to ON. To start the engine from the platform control box do the following: 5. For LPG fuel operation: Completely open the valve (6) on top of the LPG tank, (turn counterclockwise until it stops). 1.
8. Operation If you pause 30 seconds or more, after turning the Anti-Restart switch (17) to ON, an automatic protection feature will prevent the AB50J from starting. If that happens, turn the Anti-Restart switch to OFF, then try again. CAUTION 7. Pull the Emergency Stop switch (9) on the platform control box up (ON). 8. Set the Drive Range switch (10) to LOW. 9. Set the Boom Speed knob (11) as shown. 10.
8. Operation ❑ From Ground Control Box ❑ From Platform Control Box Each of the ways the platform can move is shown in the following photograph and switch illustration: When you operate from the platform control box, be sure that the lanyard of your fall restraint is attached to an anchor point on the platform mount. Also, be sure the gate is closed. Each of the ways the platform can move is shown in the following photograph and switch illustration.
8. Operation ■ Driving the AB50J The AB50J chassis can only be driven from the platform control box. You cannot drive from the ground control box. There are two blue arrows on the left side of the chassis and two yellow arrows on the right side of the chassis. ❑ Steer Left and Right Pushing the Drive/Steer controller to LEFT causes the front wheels to turn for a left turn. Pushing the Drive/Steer controller to RIGHT causes the front wheels to turn for a right turn.
8. Operation The wheels straighten in reverse order: Hold the Drive/Steer controller to the LEFT or RIGHT and the rear wheels (2) will come back to the straight ahead position before the front wheels (1) start to turn back. ❑ 4-Wheel Steer With Crab Steer If the Drive/Steer controller is not returned to the center position the wheels may return to the straight position. ■ Electrical Outlets (GFCI) at Platform The electrical box (1) has two 3 prong, 125 volt AC electrical connectors.
8. Operation ❑ AC Generator If the AB50J has the AC generator option, the power input connector (3) should be plugged into the AC generator (4). After the power input connector is plugged into the generator, turn the AC Generator switch (5) ON. For more information about the electrical outlet, see Ground Fault Circuit Interrupt in “Safety Devices” chapter 2 and Circuit Breakers in “Automatic Shut-Offs and Circuit Breakers” chapter 5.
9. Emergency Operation ■ Emergency Operation Procedures The following procedures are emergency procedures only. DO NOT use them for normal operation. Their purpose is to get the platform and operator safely to ground when a problem keeps the platform from lowering in a normal way. ❑ Operation From Platform Control Box Switch settings listed in the first four steps below must exist at the ground before emergency operation procedures will work at the platform control box: 5.
9. Emergency Operation Boom movements will be slow and have long lag times under Emergency Power from the ground controls, even with the Boom Speed switch set at the maximum speed setting. If the platform does not move and the AB50J has the optional extra battery installed, turn the Anti-Restart switch to OFF then back to ON (to cycle to the opposite battery) then go back to step 8 on page 9-1. ❑ Operation From Ground Control Box 1. Set the Battery switch (1) to ON. 6.
10. Stowing and Transporting ■ Stowing At the end of each work day (or in preparation for lifting or storage) a qualified operator should put the AB50J into its stowed position then lock it. The correct stowed position is shown here. 3. For machines equipped with optional LPG fuel, close the valve on the LPG tank (completely turned clockwise). 4. Close and lock all doors.
10. Stowing and Transporting ❑ Securing to a Transport Vehicle This procedure assumes that you have just finished loading the machine onto the transport vehicle, that the AB50J engine is still running, and that the wheels are chocked. 4. Enter the platform and attach the lanyard of your fall restraint to the lanyard anchor point (4) on the platform. 5. Use the controls on the platform control box (5) to raise the jib boom (6) to its horizontal position. 6.
10. Stowing and Transporting 8. For machines equipped with optional LPG fuel, close the valve on the LPG tank (completely turned clockwise). 11. Lock the cowling doors closed. DANGER Transporting a loose AB50J can cause Death or Serious Injury. DO NOT attach tie downs to the steering tie rods. The tie rods are not strong enough to safely hold an AB50J. 9. Attach chains to the front lifting tie down lugs (7) on the AB50J chassis. 12.
10. Stowing and Transporting ■ Towing DANGER DO NOT tow an AB50J unless it is equipped with the optional tow kit. A runaway AB50J can cause Death or Serious Injury. If you have to move an AB50J down a grade, chain a braking vehicle to the “uphill” end of the AB50J. Be certain the braking vehicle has the capacity to stop and hold both itself and the AB50J on the steepest grade they will encounter and under the prevailing environmental conditions.
11. Options ■ AC Generator CAUTION Do not use the AC generator unless the hydraulic oil is over 70°F (21°C). The output voltage of the generator depends on the temperature of the hydraulic oil. Temperature below 70°F (21°C) will cause dangerously low output voltages that can burn out some kinds of electrical equipment. The hydraulically powered, 120 volt AC generator can be used anytime the AB50J engine is running. When the generator is ON the AB50J cannot be driven in high drive range.
11. Options ■ Extra Battery ■ LPS Rating LPS is a rating devised by Underwriters Laboratory, Inc. for specialized industrial vehicles that meet certain fire safety standards. The rating specifies physical characteristics of the electrical, exhaust, and fuel systems of vehicles powered by liquefied petroleum gas engines. An LPS rating signifies fire safety characteristics that not only meet, but exceed, the minimum standards for fire safety. See ANSI/UL 558-1984 for specific information.
11. Options ■ Spark Arrestor ■ Tires The spark arrestor prevents incandescent carbon particles from coming out the tail pipe. ❑ Highway or Bar Lug Baffles in the spark arrestor slow the flow of particles through the exhaust system. The additional time spent in the exhaust system lets the carbon completely burn before it comes out the tail pipe. ■ Platform Swinging Gate Standard highway tread tires and large bar lug tires can be air filled.
11. Options ❑ Foam Filled Tires ■ Tow Kit Improper towing can cause an AB50J to break away from the towing vehicle. DANGER A “runaway” AB50J can cause Death or Serious Injury. Do not tow an AB50J faster than 10 mph (16 km/h). An AB50J can behave erratically above 10 mph (16 km/ h). Foam filled tires eliminate the possibility of air leaks or blow outs which might cause a tipover. Inspect them at the start of each work shift according to the procedures in the “Daily Inspection and Maintenance” chapter 7.
11. Options CAUTION Be certain the tow vehicle brakes are set. 2. Look at the wheels. If the hubs of all four wheels look like this, the AB50J has 4-wheel drive. 8. Remove the two bolts (1) that hold each drive wheel disconnect plate (2). 9. Turn each disconnect plate (2) over so that the nipple (3) points inward, then retighten the bolts (1). 10. At the end of the tow, before you disconnect the AB50J from the towing vehicle, turn the disconnect plates back over so the nipples are out.
Chapter 12. Troubleshooting The chart below lists situations where machine operation may be interrupted. If the problem cannot be corrected with the action listed, stow the machine and remove it from service. Repairs must be made by qualified maintenance personnel. ■ Troubleshooting Chart Problem Engine will not start from the ground control box. Cause Switches are set wrong. (Engine will not crank). Remedy Set Battery switch to ON. At the ground control box: Set the Master Key Switch to ON.
