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, contactyour Walker dealer or refer to the Walker ServiceManual.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.
