Refer to the performance charts to properly match your hydraulic system to RPH-25000 winch perform-
ance. 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 9.6 cubic inches with 15 GPM max-
imum flow rate. See page 15 for motor port size.
CLUTCH OPERATION
1.
Move the clutch control valve to the "clutch-engaged" position.
2.
Anytime the temperature is below freezing, run 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 mov-
ing 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.
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.
