MAINTENANCE

Caster Wheels

Check every 200 hours. Lift front of unit off of ground so caster wheels can rotate freely. Tighten caster bolt then back off 1/2 turn. Check that wheel rotates freely. If wheel does not rotate freely back the caster bolt off in 1/4 turn increments until wheel rotates freely.

NOTE: DO NOT add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures. Only use O.E.M. specified tires. Foam filled tires or solid tires will void the warranty

Motion Control Linkage Adjustment

This adjustment must be made with the rear wheels rotating. Raise the rear of the machine and block it up so the wheels are free to rotate

WARNING!

Keep hands, feet and clothing away from rotating tires.

Place a 2 x 4 board between the foot plate and the center of the seat to engage the seat safety switch.

Loosen the nuts (A & B) directly behind each ball joint on linkages (C). See illustration.

Start the engine. The park brake must be engaged and the motion control levers in the neutral slots to start the engine. Run the engine approximately half throttle. Release park brake to allow the wheels to rotate.
