Inching
is used for a fi ne control of the winch speed.
When the power control lever is slowly moved to a
position between
BRAKE-ON
and
LINE-IN
or between
BRAKE-ON
and
LINE-OUT
, inching occurs. The normal
adjustment of inching for
LINE-IN
is different from the
adjustment for
LINE-OUT
. These adjustments can
be modifi ed by changing the overlap pressures of the
modulator valves. This change is necessary for some
customer operations. The following paragraphs describe
the normal adjustments for inching.
WARNING
Excessive inching will accelerate clutch
and brake wear, and cause winch
overheating.

Inching (LINE-IN)
. This operation is used to slowly move
a load toward the tractor. The control valve will cause the
oil pressure to slowly release the brake and slowly apply
the
LINE-IN
clutch. As the brake is released, the clutch
takes control and begins to move the load.

CONTROL LEVER
POSITION
Inching (LINE-OUT)
. This operation will release the brake
before the
LINE-OUT
clutch is applied. This adjustment
permits the weight of the load 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. The
LINE-OUT
clutch
is not applied until the operator moves the power control
lever more toward the
LINE-OUT
position. When the power
control lever is moved so that the
LINE-OUT
clutch is
engaged, the speed that the drum unwinds is controlled
by the rpm of the tractor PTO.
