9.14.6 Parking Brake Switch

The parking brake switch (1) is located on the dash to the

left of the steering column and is pressed or “snapped”

into a rectangular switch bezel. The parking brake switch

must be ENGAGED to permit engine starting.

Note: The parking brake may be used to stop in an

EMERGENCY situation; however, notify the operator to

use caution as the stop will be abrupt and the operator

and the load may be jolted forward unexpectedly.

The parking brake switch is a two-position toggle switch;

the two positions are ENGAGED (3) and

DISENGAGED (4).

The switch is marked with a symbol (5) on the lower

portion of the switch. When ENGAGED, the parking

brake switch completes the parking brake circuit, and the

indicator (2) on the front dash panel illuminates. The

parking brake solenoid (6) on the accumulator charge/

secondary function valve (7) is normally de-energized,

allowing the parking brake to engage. When the parking

brake solenoid is energized, the parking brake is

DISENGAGED.

This system is designed so that, when electrical power is

OFF, the parking brake is ENGAGED. (Refer to Section

10, “Stabil-TRAK™ System,” page 10.10.)

a. Parking Brake Switch Removal

1. Unlock and open the engine cover (8).

2. If the vehicle has dual batteries, disconnect both

negative battery cables (10 and 11) from both

batteries.

To access the lower battery (12), loosen the

knob (13) far enough so that the lip (14) on the upper

battery box clears the knob. Lift up the upper battery

box (15) and swing it out, so that the box clears the

hydraulic tank support bracket, to gain access to the

lower negative battery cable (10). Disconnect the

lower negative battery cable.
