IMPORTANT NOTE: WHEN THE WIRE ROPE IS BEING PAYED-OUT UN-
DER POWER, THE WINCH IS BEING DRIVEN AGAINST THE BRAKE.
CONSEQUENTLY, EXCESSIVE HEAT WILL DEVELOP IN THE AUTO-
MATIC BRAKE HOUSING, POSSIBLY CAUSING THE OIL TO BOIL OVER.
If it is necessary to pay the wire rope out under power, do not operate in this man-
ner for more than one hundred feet. Drive the winch at slow speed only.
To pay-out wire rope over one hundred feet in length, the winch drum should be
placed in the free spool position. Care should be taken to operate the drag brake
properly to prevent wire rope entanglement.
PREPARING FOR
OPERATION Before placing the winch in service the following checks should be made:
Make certain that the winch assembly is properly secured to the chassis frame.
The operator should have a complete understanding of all functions and the loca-
tion and operation of all controls.
The wire rope should be spooled on the drum with tight, even coils and lays.
It is not necessary to have the dram filled with wire rope. Additional pulling capa-
bility can be obtained by only installing a slight excess of the maximum length re-
quired for the job.
Check the hydraulic system for the correct pressure and flow.
Check the hydraulic system to make certain that the reservoir is filled to the correct
level with the proper grade of oil.
Make certain that the reservoir shut-off valve is open.
Check all winch and winch accessory gear housings for the correct oil level and
grade (see lubrication section - page 8).
Engage the hydraulic system and allow the oil to circulate and warm up for a few
minutes before operating the winch. This is particularly important during extremely
cold weather.
Check the body load area in a triangular section between the tail shelf sheave and
both drum flanges for obstructions that will restrict the travel of the wire rope.
OPERATION THE
WINCH Start the truck engine and engage the power take-off.
Check the body load area to make certain there are no tools or equipment to restrict
wire rope travel or level wind movement.
Check the winch dram for extreme wire rope entanglement or erratic build-up in
any location.
With rotation stopped, place the winch clutch control lever in the clutch engaged or
pull-in position.
Operate the directional control valve for the desired direction of drum rotation. ;
Pull the load steadily and adjust the truck engine speed to satisfy conditions.
To stop the winch, release the directional control lever; return the engine to idle.
When free spool is required, stop the drum rotation and pull the clutch control lever
out.
