60Maintenance Instructions CHECKING/SERVICINGSafety Switch SystemWARNINGIt is important to check and maintain thesafety switch system for safe operation ofthe machine.There are three (3) safety interlock switches on thetractor; Seat Switch, FSC Neutral - Park Switch, andPTO Switch.If any of the following conditions occur during start-ing or operating, a safety interlock switch may bemalfunctioning. Contact your Walker dealer for trou-bleshooting and/or replacement.• With or without an operator in the seat, the enginestarts with the Forward Speed Control (FSC) and/orthe PTO engaged.• With an operator in the seat, the engine starts butdies soon after the Forward Speed Control (FSC) orPTO is engaged.• Without an operator in the seat, the engine startsand continues to run with the Forward Speed Control(FSC) and/or PTO engaged.• With an operator in the seat, the Forward SpeedControl (FSC) and PTO disengaged and panel hornworks, but the starter is not engaging.Forward 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, contactyour Walker dealer or refer to the Walker ServiceManual.
