HYDRAULIC SYSTEM REQUIREMENTS

Refer to the performance charts, below, to properly match your hydraulic system to 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 10.3 cubic inches/rev with 60 GPM maximum flow rate. Motor has (2) 1”-12 SAE straight thread o-ring ports.

Note: A motor spool (open center) directional control valve is required for brake operation.

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 around the drum and into the track on drum flange. Secure using supplied u-bolt #62 and (2) washers #64 and (2) nuts #65.

3. Carefully run the winc h in the “reel-in” direction. Keeping tensio n on end of cable, spool all the cable onto the cable drum, taking care to form neatly wrapped layers.

4. After installing cable, band brake is used to prevent bird nesting while pulling out cable, when clutch is disengaged.

CLUTCH OPERATION

WARNING: CLUTCH MUST BE FULLY ENGAGED BEFORE STARTING THE WINCHING OPERATION.

To engage clutch:

1. Move clutch control to engage the clutch.

2. Run the motor in the cable out direction until the drum begins to turn.

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. Move the clutch control to disengage the clutch. The cable may now be spooled off.

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.

2. Check the pressure relief plug on the gear housing cover and the brake housing cover. Be sure they

are not plugged.

3. Lubricate cable with light oil.

4. Lubricate drum bushings with grease. It is necessary to remove cable to expose the grease zerks on drum. Use high quality lithium grease for best results.

5. Apply a high quality lithium grease to clutch spline. Apply band brake to control drum. Declutch drum and apply grease to spline between clutch and drum.

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.

C. ANNUALLY

Drain the oil from the winch annually or more often if winch is used frequently.

2. Refill the winch to the oil level plug with all purpose GL-5 oil, (see page 6) for gear lube compatible with

your climate.

3. Inspect winch for damage and wear.

INSTRUCTIONS FOR DISASSEMBLY

1. Remove wire rope from drum.

2. Drain oil from winch by removing (2) plugs #54, removing the lower plug first.

3. When replacing lubricant, use 192 oz of applicable lube for your climate from table on page 6 adding 4 oz at #44 and 188 oz at # 55.

4. Remove (2) nuts #408b from air cylinder #408a. Air cylinder may now be removed. If needed, mounting bracket #401 may be removed by removing pin #404 from pin #405 and then sliding pin out of mounting bracket. Brake band #5 may be expanded over drum flange to barrel for easiest removal.

NOTE: BRAKE BAND FITS OVER DRUM FLANGE
