Maintenance Instructions
Safety Switch System
It is important to check and maintain the
safety switch system for safe operation of
the machine.
There are three (3) safety interlock switches on the
tractor; Seat Switch, FSC Neutral-Park Switch, and
PTO Switch.
NOTE: There is a 1/2 second time delay function on
the seat switch to avoid engine power interruption
when driving over bumps.
If any of the following conditions occur during start-
ing or operating, a safety interlock switch may be
malfunctioning. Contact your Walker dealer for trou-
bleshooting and/or replacement.
●
With or without an operator in the seat, the en-
gine starts with the Forward Speed Control (FSC)
and/or the PTO engaged.
●
With an operator in the seat, the engine starts but
dies soon after the Forward Speed Control (FSC) or
PTO is engaged.
●
Without an operator in the seat, the engine
starts and continues to run with the Forward Speed
Control (FSC) and/or PTO engaged.
●
With an operator in the seat, the Forward Speed
Control (FSC) and PTO disengaged and panel horn
sounding, the starter will not engage.

WARNING
Forward Speed Control Friction Lock
The 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 heavy
to make moving the FSC control difficult (too much
friction). The procedure for checking the FSC fric-
tion lock is as follows:
1.
With the engine off, place the FSC in the full
FORWARD position and pull both steering le-
vers back; the FSC lever should not move. If
the FSC lever moves back when the steering
levers are pulled back, the friction needs to be
increased.
2.
With the steering levers held back, move the
FSC lever back from the FORWARD position.
With a proper amount of friction adjusted, the
FSC lever should move back with a slight
amount of resistance (friction). If the FSC lever
movement is "stiff", the friction needs to be
decreased.
If the FSC friction lock needs to be adjusted, refer to
ADJUSTMENTS for Forward Speed Control Fric-
tion Lock in this section.
