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. Place taped end of cable through roller guide and into hole in cable drum as shown below. Use
3/8”-16NC X 3/8” Lg. Hex socket drive setscrew to secure cable to drum.
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.
After installing cable, check freespool operation. Disengage clutch and pull on cable at walking
speed. If cable “birdnests”, loosen jam nut #34 and turn 3/8”-16NC capscrew #29 clockwise to
increase drag on drum. If cable pull is excessive, loosen 3/8”-16NC capscrew #29 by turning
counterclockwise. Tighten jam nut when proper setting is obtained.

HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, to properly match your hydraulic system to Linemaster 20K winch
performance. The charts consist of:
(1) Line pull (lb.) first layer vs. working pressure (PSI) and (2) Line speed, first layer (FPM) vs. gallons per
minute (GPM). Performance based on a motor displacement of 14.9 cubic inches with 30 GPM maximum
flow rate. Motor has (2) 1.062-12 SAE straight thread o-ring ports.
Note: A motor spool (open center) directional control valve is required for brake operation.

CLUTCH OPERATION
WARNING: CLUTCH MUST BE FULLY ENGAGED BEFORE STARTING THE WINCHING OPERATION.
To engage clutch:
1. Grasp shift lever and push toward drum to the “In” position.
2. If shift lever detent does not engage to the detent hole, then the clutch is not fully engaged. The
cable drum may need to be manually rotated slightly while pushing on the shift lever to align the
clutch splines.
WARNING: DO NOT DISENGAGE CLUTCH UNDER LOAD.
To disengage clutch:
1. Run the winch in the "cable out" direction until the load is off the cable.
2. Grasp the shift lever and pull away from drum to the “Out” position until shift lever detent engages
in detent hole. If there is resistance in moving the shift lever, the cable drum may be manually
rotated in the cable “Out” direction thereby relieving the preload and allowing the lever to shift.
The cable may now be pulled off by hand.
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.
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.
Check the pressure relief plug on the gear housing cover. Be sure that it is not plugged. Lubricate
2.
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 8 or better bolts.
2. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.
