Service Manual Manual

The inching feature allows the operator, when
carrying a load, to move the handler very slowly for
maneuvering in tight places.
To operate the inching feature, the operator depresses
the brake-inching foot pedal (A) approximately 1/4"
- 1/2". This creates movement of the linkage (B)
making contact with the low torque inching switch
(D). As this first movement occurs and physical
contact is broken, the switch is energized and it
activates the low torque inching solenoid valve (E).
This sends pilot circuit oil down to the de-clutch
valve (F) on the transmission and the transmission
de-clutches and there is no power to the front axle.
As the linkage (B) continues to move, the arm on the
inching valve (C) moves. This movement causes pilot
INCHING
control pressure to bleed off to tank. thereby
metering the Forward/Reverse valve to neutral.
As the operator continues to depress the brake-
inching pedal (A) and the inching valve (C) rotates.
the pressure controlling the Fwd/Rev Valve varies.
Depending on the stroke of the plunger in the
Fwd/Rev control valve, varying volume of oil is
routed on to the series/parallel valve and to the rear
drive motors.
The further down the operator depresses the brake-
inching pedal, the lower the oil volume going to
the motors.
As the operator continues to depress the brake-
inching pedal, the front axle brakes are applied and
normal braking occurs.
