56Maintenance Instructions CHECKING/SERVICING/REPLACING/REPAIRINGForward Speed Control Friction LockThe FSC friction lock is designed to hold the se-lected forward travel speed when the steering le-vers are moved and yet the friction is not too heavyto make moving the FSC control difficult (too muchfriction). The procedure for checking the FSC fric-tion lock is as follows:1. Place the FSC in the full FORWARD positionand pull both steering levers back; the FSC le-ver should not move. If the FSC lever movesback when the steering levers are pulled back,the friction needs to be increased.2. With the steering levers held back, move theFSC lever back from the FORWARD position.With a proper amount of friction adjusted, theFSC lever should move back with a slightamount of resistance (friction). If the FSC levermovement is “stiff”, the friction needs to bedecreased.If the FSC friction lock needs to be adjusted, refer toADJUSTMENTS for Step 7 - Forward Speed Con-trol Friction Adjustment in this section.REPLACING/REPAIRINGDANGERTo prevent accidental starting of the en-gine when replacing parts or repairing themachine, remove the key from the ignitionswitch and disconnect the spark plugwires.IMPORTANT: ALWAYS use genuine factory re-placement parts. Substitute parts CAN result inproduct malfunction and possible injury to the op-erator and/or others.Drive BeltsThere are three (3) individual belts on the ma-chine:• Engine/PTO Belt (Matched Set of 2)• Ground Drive BeltThe belts may be removed and replaced using theprocedures described on the following pages.Belt LocationsGroundDrive BeltEngine/PTO Belts(Matched Set of 2)
