Safety Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. Safe Operating Practices This product is capable of amputating hands and feet. Always follow all safety instructions to avoid serious injury or death.
Safety • Do not carry a load with the arms raised. Always carry loads close to the ground. Do not step off of the platform with the load raised. • Do not over-load the attachment and always keep the load level when raising the loader arms. Logs, boards, and other items could roll down the loader arms, injuring you. • Never jerk the control levers; use a steady motion. • Keep your hands, feet, hair, and loose clothing away from any moving parts. • Operate only in daylight or good artificial light.
Safety • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction. • Avoid starting or stopping on a slope. If tires lose traction, proceed slowly, straight down the slope. • • Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the traction unit uphill. Do not operate near drop-offs, ditches, or embankments. The traction unit could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.
Safety • Stop and inspect the equipment if you strike an object. Make any necessary repairs before restarting. • Use only genuine replacement parts to ensure that original standards are maintained. • Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes, and clothing. Protect your face, eyes, and clothing when working with a battery. • Battery gases can explode. Keep cigarettes, sparks and flames away from the battery.

USE Traction Unit 1 Valve Lever 1 Key 2 Start engine Hydraulic oil filter 1 Break-in oil change Install valve lever Installing the Valve Lever Activating the Battery 1. The traction unit is shipped with a dry battery. Bulk electrolyte with 1.260 specific gravity must be purchased from a local battery supply outlet. Thread the lever into the speed selector valve (Fig. 1). Note: 2.
Assembly 3. Gently push the hydraulic hoses aside and lift the battery out of the chassis. 5. POTENTIAL HAZARD • Battery electrolyte contains sulfuric acid which is a deadly poison and it causes severe burns. Leave the covers off and connect a 3 to 4 amp battery charger to the battery posts (Fig. 4). Charge the battery at a rate of 4 amperes or less for 4 hours (12 volts). 4 2 3 WHAT CAN HAPPEN • If you drink electrolyte you could die or if it 1 gets onto your skin you will be burned.
Assembly 7. Slowly pour electrolyte into each cell until the level is once again up to the upper line on the battery case (Fig. 3) and install covers. 8. Install the battery into the chassis (Fig. 2). 9. Secure the battery in chassis with the bar and wing nuts removed previously (Fig. 2). 10. Using the bolt and wing nut supplied with the battery, connect the positive (red) cable to the positive (+) battery post (Fig. 2). Slide the rubber cover over the battery post. 11.

Check Before Operating Stability Data The following table lists the maximum slope recommended for the traction unit in the positions listed in the table. Slopes over the listed degree may cause the traction unit to become unstable. The data in the table assumes that the loader arms are fully lowered and that the factory installed tires are on the traction unit, inflated to the recommended pressure; raised arms and other tire types or pressure may affect the stability.
Before Operating Before operating, check the fuel and oil level, remove debris from the traction unit, and check the tire pressure. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines. Adding Fuel POTENTIAL HAZARD • When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. WHAT CAN HAPPEN • A fire or explosion from gasoline can burn you, others, and cause property damage.
Check Before Operating Filling the Fuel Tanks 1. Park the traction unit on a level surface, lower the loader arms, and stop the engine. 2. Remove the key and allow the engine to cool. 3. Clean around the fuel tank caps and remove them. 4. Use a funnel and add unleaded regular gasoline to each fuel tank, until the level is 1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of each filler neck. IMPORTANT: This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full. 5.
Check Before Operating Removing Debris from the Traction Unit Use only Group 1 ISO type 46/68 anti–wear hydraulic fluids, recommended for ambient temperatures consistently below 100_ F, such as Toro Hy–Pro, Mobil Fluid 424, or other equivalent fluid. IMPORTANT: Operating the engine with a blocked grass screen, dirty or plugged cooling fins, and/or cooling shrouds removed, will result in engine damage from overheating. 1.
Check Before Operating Tire pressure Maintain the air pressure in the tires as specified. Check the tires when they are cold to get the most accurate reading. Pressure: 15–20 psi Note: Use a lower tire pressure (15 psi) when operating in sandy soil conditions to provide better traction in the loose soil. 1 m–1872 Figure 7 1.

WHAT CAN HAPPEN • The operator could be seriously injured.
Operation Controls Traction Control Levers Become familiar with all the controls (Fig. 9) before you start the engine and operate the traction unit. To move forward, move the traction control levers forward. To move rearward, move the traction control levers rearward. 5 3 1 2 To go straight, move both traction control levers equally. 4 To turn, move the lever located on the side you want to turn back toward the neutral position while keeping the other lever engaged. 6 8 7 m–4388 Figure 9 1. 2.
Operation Speed Selector Lever Move the speed selector lever to the fast (rabbit) position to set the traction drive, loader arms, and attachment tilt to high speed and the auxiliary hydraulics to low speed. Move the speed selector lever to the slow (turtle) position to set the auxiliary hydraulics to high speed and the traction drive, loader arms, and attachment tilt to low speed. powering attachments; however, the two systems share the same hydraulic pumps. Using the flow divider control (Fig.
Operation that require the nine o’clock position; however, the trencher does work best if you set it close to nine o’clock so that the traction unit will creep slowly when trenching. Note: IMPORTANT: If the engine is run at high speeds when the hydraulic system is cold (i.e., when the ambient air temperature is around freezing or lower), hydraulic system damage could occur.
Operation • To turn, move the lever located on the side you want to turn toward the neutral position while keeping the other lever engaged. • To slow or stop, move the traction control levers to neutral. Note: The farther you move the traction control levers in either direction, the faster the traction unit will move in that direction. Moving a Non-functioning Traction Unit IMPORTANT: Never tow or pull the traction unit. Rotating the wheels manually will cause damage to the hydraulic wheel motors. 1.
Operation Using the Cylinder Locks POTENTIAL HAZARD • The loader arms may lower when in the raised position. WHAT CAN HAPPEN • Anyone under the loader arms may be injured or crushed. HOW TO AVOID THE HAZARD • Always install the cylinder locks when doing maintenance that requires raised loader arms. 2. Raise the loader arms to the fully raised position. 3. Stop the engine. 4. Remove the clevis pin and cotter pin securing each cylinder lock. 5. Remove the cylinder locks. 6. Lower the loader arms.
Operation Installing and Removing Attachments 6. Raise the loader arms while tilting back the mount plate at the same time. IMPORTANT: The attachment should be raised enough to clear the ground, and the mount plate should be tilted all the way back. Connecting an Attachment IMPORTANT: Use only Toro approved attachments. Attachments can change the stability and the operating characteristics of the traction unit. The warranty of the traction unit may be voided if used with unapproved attachments. 7.
Operation Note: When you connect the attachment male connector first, you will relieve any pressure build up in the attachment. POTENTIAL HAZARD • Hydraulic fluid escaping under pressure can penetrate skin and cause injury. WHAT CAN HAPPEN • Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
