ADJUSTMENTS MOTION CONTROL LINKAGE ADJUSTMENT: 1. This adjustment must be made with the drive wheels rotating. Raise rear of the unit and block it up so the wheels are free to rotate. CAUTION: Keep hands, feet and clothing away from rotating tires. 2. Tilt seat forward and remove the seat lanyard from seat so the seat can rotate down onto the frame. Make sure the seat is adjusted toward the rear of the unit so it clears the controls on the console. 3.
OPERATING INSTRUCTIONS NOTE: To begin motion the operator must be in the seat and the brake disengaged before the levers can be moved from the neutral slots or the engine will kill. By moving the levers an equal amount forward or back the mower will move in a straight line in that direction. Movement of the right lever forward will cause the right wheel to rotate in a forward direction. Movement of the left lever forward will cause the left wheel to rotate in a forward direction.
OPERATING INSTRUCTIONS STARTING AND OPERATION: 1. Operator must be sitting in the seat. Engage park brake, blades off and place the motion control levers in the neutral slots. (See figure 6) 2.Kawasaki engines use a combination choke-throttle. Adjust throttle to choke (if needed) turn key and release as soon as engine starts, and adjust 1/2 throttle. Kohler engines require use of a ckoke control separate from the throttle. 3. Release park brake. 4. Close motion control levers. 5.
MAINTENANCE 5. Hardware: Stop engine and remove key thoroughly inspect the entire machine for any missing or loose hardware. Check daily. 6. Air cleaner: Stop engine and remove key. Remove plastic cover and loosen wingnut on the air cleaner. Remove the foam pre-cleaner and wash or replace if needed. Inspect paper filter and replace if dirty. Check every 25 hours, daily if in very dirty conditions. Fuel efficiency, engine RPM, and available power goes down rapidly if the air filter is dirty.
MAINTENANCE 13. Fuel filter: Replace annually or as needed. 14. Hydraulic filter and oil: Change every 500 hours or yearly. Stop engine and remove key. Clean around the filter and the drain plug on the bottom side of the tank. Remove the filter and allow any oil to drain from the filter head. Then replace with new filter.
