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.
