NOTE: The rated line pulls shown are for the winch only. Consult the wire rope manufacturer for wire rope ratings.

WARNINGS:

VERIFY PROPER COUNTERBALANCE VALVE CARTRIDGE AND PLUG POSITION FOR SPECIFIC INSTALLATION.

CLUTCH MUST BE TOTALLY ENGAGED BEFORE STARTING THE WINCHING OPERATION. DO NOT START WINCH MOTOR BEFORE ENGAGING CLUTCH. DO NOT DISENGAGE CLUTCH UNDER LOAD. STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS. STAND CLEAR OF CABLE WHILE PULLING. DO NOT TRY TO GUIDE CABLE. DO NOT EXCEED MAXIMUM LINE PULL RATINGS SHOWN IN TABLE. DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT PEOPLE. A MINIMUM OF 5 WRAPS OF CABLE AROUND THE DRUM BARREL IS NECESSARY TO HOLD THE

LOAD. CABLE ANCHOR IS NOT DESIGNED TO HOLD LOAD.

WINCH MOUNTING

Use (8) 3/4" diameter grade 5 or better bolts to attach winch to the wrecker. Before operating the winch for the first time, remove the cover from the breather vent at the back of the air

cylinder and the relief fitting on top of the clutch housing.

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.

HYDRAULIC SYSTEM REQUIREMENTS

Refer to the performance charts to properly match your hydraulic system to RPH-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 based on a motor displacement of 9.6 cubic inches with 25 GPM maximum flow rate. See page 14 for motor port size.

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 0o F/-18o 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.

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.
