Inching (LINE-IN)
. This operation is used to slowly move
a load toward the tractor. As the control lever is moved
gradually towards the
LINE-IN
position, the control valve
will cause the oil pressure to slowly release the brake and
slowly apply the forward clutch. As the brake is released,
the clutch takes control and begins to move the load.
Inching (LINE-OUT)
. This operation will release the brake
as the reverse clutch is applied. This permits the weight of
the load, with assistance from the reverse clutch, to unwind
wire rope from the winch drum against the resistance of
the brake. The operator controls the resistance of the brake
by the position of the power control lever.
Inching (BRAKE-OFF).
This operation is used to partially
release a load. For example, when an operator wants to
maintain the position of a load while climbing a slippery
slope, partial brake off will allow the load to remain

Inching
is used for fi ne control of the winch speed.
When the joystick is slowly moved to a position between
BRAKE- ON
and
LINE-IN
or between
BRAKE-ON
and
LINE-OUT
, inching occurs. Any adjustments require
computer program changes and may be necessary
for some customer operations. Contact Allied Systems
Company if inching needs adjustment. The following
paragraphs describe the normal procedures for inching.
NOTE: Inching will add heat, and accelerate wear of
the clutches and brake.
