HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts to properly match your hydraulic system to HDP-50000 winch performance.
The charts consist of:
(1) Line pull (lb.) first layer vs. working pressure (PSI) and (2) Line speed (FPM) first layer vs. flow (GPM).
Performance is based on a motor displacement of 11.9 cubic inches with 25 GPM maximum flow rate.
See page 10 for motor port size.

WINCH OPERATION
The best way to get acquainted with how your winch operates is to make test runs before you use it. Plan
your test in advance. Remember, you hear your winch, as well as see it operate. Learn to recognize the
sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting. Gain confidence in
operating your winch and its use will become second nature with you.
The uneven spooling of cable, while pulling a load, is not a problem, unless there is a cable pileup on one end
of drum. If this happens, reverse the winch to relieve the load and move your anchor point further to the center of the vehicle. After the job is done you can unspool and rewind for a neat lay of the cable.
CLUTCH OPERATION
To engage clutch:
1. Move the clutch control valve to the “clutch engaged” position.
2. Anytime the temperature is below freezing, run the motor in the “cable out” direction only until the
drum starts to turn. In extreme cold temperatures (below 0˚ F/-18˚ C), pull out on the cable by hand
only until the drum starts to turn.
3. Wait at least 3 seconds for the clutch to fully engage, after which the winch is ready to winch in the
cable.
WARNING: Do not attempt to engage the clutch by first running the winch motor and then moving the
clutch control valve to the "clutch-engaged" position while the motor is running. Do not start picking up
the load at the same time the clutch is being engaged.
To disengage clutch:
1. Run the winch in the "cable out" direction until the load is off the cable.
2. Move the clutch control valve to the "clutch-disengaged" position.
3. The cable may now be pulled off by hand.
CABLE INSTALLATION
1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of wire rope, opposite hook, with plastic or similar tape to prevent fraying.
2. Insert the end of cable, opposite hook end, into the hole in drum barrel. Secure cable to drum barrel,
using setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.
3. Carefully run the winch in the “reel-in” direction. Keeping tension on end of cable, spool all the cable
onto the cable drum, taking care to form neatly wrapped layers.

MAINTENANCE
Adhering to the following maintenance schedule will keep your winch in top condition and performing as it should with a minimum of repair.
A. WEEKLY
1.
Check the oil level and maintain it to the oil level plug. If oil is leaking out, determine location and
repair.
2.
Check the pressure relief plug in the gear housing cover. Be sure that it is not plugged.
3.
Lubricate cable with light oil.
B. MONTHLY
1.
Check the winch mounting bolts. If any are missing, replace them and securely tighten any that are
loose. Use grade 5 or better bolts.
2.
Inspect the cable. If the cable has become frayed with broken strands, replace immediately.
C. ANNUALLY
1.
Drain the oil from the winch annually or more often if winch is used frequently.
2.
Fill the winch to the oil level plug with clean kerosene. Run the winch a few seconds with no load in
the reel in direction. Drain the kerosene from the winch.
3.
Refill the winch to the oil level plug with all-purpose SAE 75W-90 synthetic gear oil.
4.
Inspect frame and surrounding structure for cracks or deformation.
