Setup Media and Additional Parts Description Use Qty. Operator's Manual 1 Read before operating the machine. Key 2 Start the machine. DANGER 1 Charging or jump starting the battery may produce explosive gases. Battery gases can explode causing serious injury. Checking Tire Pressure • Keep sparks, flames, or cigarettes away from battery. No Parts Required • Ventilate when charging or using battery in an enclosed space.
1. Turn the key in the ignition switch to the OFF position and remove the key. 2. Measure the voltage of the battery with a voltmeter. 3. Use the table below to locate the charge state or the battery, and if needed, the battery-charger setting and charging interval recommended to charge the battery to 12.6 V or greater.
4 Removing Cylinder Stop (for Model 33518) No Parts Required Procedure Note: The tines must be in the raised position before removing the cylinder stop. Running the engine will charge the hydraulic system and raise the tines. 1. Add a small amount of fuel to the fuel tank; refer to Adding Fuel (page 17). Figure 5 2. Open the fuel-shutoff valve by aligning the lever for the fuel-shutoff valve with the fuel line; refer to Opening the Fuel Shut-off Valve (page 22). 1. Hairpin 3. Cylinder stop 2.
Tine-Pressure Control Product Overview The tine-pressure control is located on the left side of the control console (Figure 8). Use the tine-pressure control to adjust the downward pressure on the tines and core depth. Rotate the control counterclockwise to decrease the pressure and the length of the aeration plug; rotate clockwise to increase pressure and increase the length of the aeration plug. Figure 6 1. Platform 4. Engine controls 2. Parking-brake knob 5. Fuel cap 3.
lever forward. To reduce the choke, move the choke lever backward. On/Off Tine Ground Engagement Foot Switch Note: Pull the choke lever back into the detent to set the choke to the OFF position. Located above the tine down pressure control on the control console. Note: Do not run a warm engine with choke in the ON position. To enable the tines ground engagement, push down on the top of the switch. To disable the tines ground engagement, push down on the rear of the switch.
Drive Wheel Release Valves Operation The drive wheel release valves are located on the left and right sides underneath the front of the unit. Note: Determine the left and right sides of the machine from the normal operating position. Note: During normal operating conditions, the washer on the lever is positioned inside the slots. Checking the Engine-Oil Level If you need to push the machine by hand, make sure that the valves are in the “released” position (Figure 11).
Adding Fuel Fuel tank capacity: 18.9 L (5 US Gallons) • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • ETHANOL: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Fueling the Machine 1. Clean around the fuel-tank cap.
CAUTION Raising the machine for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the machine to fall, which could cause injury. Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support. 3. Turn the key in the ignition switch to the ON position, and move throttle level ahead to 1/2 throttle position.
Starting the Engine 1. Disconnect the spark-plug wires; refer to Checking the Spark Plugs (page 34). 1. Move the traction-control levers to the NEUTRAL position and set the parking brake; refer to Traction-Control Levers (page 14)and Parking-Brake Handle (page 15). 2. While on level ground, block the wheels of the machine to prevent unintended movement. 3. Disengage the parking brake; refer to Parking-Brake Handle (page 15). Note: To start the engine, the parking brake must be engaged.
4. Adjust the throttle for the working conditions; refer to Throttle Lever (page 14). Adjusting the Tine Down Pressure 4. Allow the engine to run for a minimum of 15 seconds, then turn the key in the ignition switch to the OFF position to stop the engine; refer to Ignition Switch (page 15). Important: Keep the drive tires on the ground at all times. 5. Set the parking brake; refer to Parking-Brake Handle (page 15). Adjust the plug depth by rotating the tine pressure control as follows: 6.
Figure 20 To turn left or right, release pressure on the traction-control lever toward the desired turn direction. Figure 19 To make zero turns, lift your foot off of the tine-elevation switch to raise the tines. The head will raise in 1 second. To turn left or right, pull the traction-control lever back toward neutral in the desired turn direction. The tines can be in the down position when making gradual turns. Important: Do not make a zero turn when the tines are in the down position. 3.
Adjusting the Tine Down Pressure Traction-Control Levers (page 14)and Parking-Brake Handle (page 15). Important: Keep the drive tires on the ground at all times. Note: To start the engine, the parking brake must be engaged. (It is not necessary for the operator to be on the platform.) Adjust the plug depth by rotating the tine pressure control as follows: 2. Place the throttle lever midway between the SLOW and FAST positions; refer to Throttle Lever (page 14).
4. Allow the engine to run for a minimum of 15 seconds, then turn the key in the ignition switch to the OFF position to stop the engine; refer to Ignition Switch (page 15). 5. Set the parking brake; refer to Parking-Brake Handle (page 15). 6. Remove the key to prevent children or other unauthorized persons from starting the engine. 7.
4. Load the machine onto the trailer or truck. 5. Stop the engine, remove the key, set the brake, and close the fuel valve. 6. Set the parking brake and block the tires. 7. Use the tie-down points on the machine to securely bind the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 27). Note: Refer to your local ordinances for specific trailer and tie-down regulations.
WARNING Loading the machine onto a trailer or truck increases the possibility of backward tip-over, and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp. • Use only a single, full-width ramp; do not use individual ramps for each side of the machine. • If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the machine. • Do not exceed a 15-degree angle between ramp and ground, or between a ramp, a trailer, or a truck.
Maintenance WARNING WARNING While you are maintaining or adjusting the machine, someone could start the engine. Accidentally starting the engine could seriously injure you or other bystanders. The engine can become very hot. Touching a hot engine can cause severe burns. Allow the engine to cool completely before service or making repairs around the engine area. Remove the key from the ignition switch, engage parking brake, and pull the wire(s) off the spark plug(s) before you do any maintenance.
