Verify Interlock System Operation

The purpose of the interlock system is to prevent the en-
gine from cranking or starting unless the brake pedal is
depressed and the hydraulic lift lever is in the neutral po-
sition.
CAUTION
Do not disconnect safety switches. They are for
the operator's protection. Check the operation of
the interlock switches daily for proper operation.
Replace any malfunctioning switches before op-
erating the machine.
To verify brake interlock switch operation:
1. Sit on operator's seat and engage parking brake.
Move transmission lever to NEUTRAL or PARK position.
Make sure that hydraulic lift lever is in neutral position.
2. Without depressing the brake pedal, rotate ignition
switch to START position.
3. If engine cranks or starts, there is a malfunction in the
interlock system that must be repaired before operating
vehicle.
