Operating Procedures
The control lever assembly has a power control lever for
winch control. The control lever is connected to the winch
through a control cable. The power control lever, which
is connected to the spool in the control valve, is used to
select one of the following operations:
• BRAKE-OFF
• LINE-OUT
• BRAKE-ON
• LINE-IN
BRAKE-OFF
is the only detented position on the control
lever (electronic controls) or control lever (power controls),
and the operator must pull the lever to release it from that
position. A spring arrangement on the lever returns the
lever from the
LINE-IN
and
LINE- OUT
positions to the
BRAKE-ON
position. With the lever in the
BRAKE-OFF
position, oil pressure releases the brake but wire rope
cannot be pulled from the winch by hand because of
friction in the clutches, brake and gear train. The
BRAKE-
OFF
position is used when the operator has a load
attached to the winch wire rope. The operator can move
the tractor forward without moving the load.
LINE-OUT
position applies the reverse clutch and
releases the brake. The winch will unwind the wire rope
at a speed controlled by the PTO speed of the tractor and
the weight of the load.
BRAKE-ON
is a neutral position. No hydraulic pressure
is applied to the brake or the clutches. Springs apply the
brake so that the winch drum will not rotate.
LINE-IN
position applies the forward clutch and releases
the brake. The winch will wind the wire rope at a speed
controlled by the PTO speed of the tractor.
Inching
is used for fi ne control of the load. When the
control lever is slowly moved to a position between
BRAKE-ON
and
LINE-IN
or between
BRAKE-ON
and
LINE-OUT
, inching occurs.
NOTE: Inching rapidly increases the temperatures of
the clutch, the brakes and the oil, and will accelerate
clutch and brake wear.
