Ramsey Winch RPH-25000 (JERR-DAN) - Manual (Page 4)

WINCH ANGLE MOUNTING
Use (8) 5/8" diameter grade 5 or better bolts to attach mounting angles to the wrecker.
CABLE INSTALLATION / TENSIONER OPERATION
CAUTION: THE CABLE TENSIONER IS NOT INTENDED TO BE ENERGIZED ON A BARE DRUM. Before
applying air to the cable tensioner, engage the clutch and run the winch in the reel in direction winding one
full wrap of cable on the drum. This prevents damage to the cable tensioner.
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.
CAUTION: WINCH IS DESIGNED FOR UNDERWIND CABLE USE ONLY.
2. Insert the end of cable, opposite hook end, under drum barrel and into the cable anchor hole in drum
barrel. Secure cable to drum barrel, using set screw furnished with winch. TIGHTEN SETSCREW
SECURELY.
3. Engage the clutch and carefully run the winch in the "reel-in" direction. Keeping tension on end of
cable, spool about five wraps of cable onto the drum and stop. Using a hammer, tap these five
wraps tightly over against the cable anchor flange side of the cable drum. Finish winding all the
cable onto the cable drum. As cable winds onto the drum, watch the tensioner. Tensioner must be
free to move without obstruction to function properly. If tensioner touches any surrounding struc-
ture, correct the problem.
Adjust the free-spool effort of the cable tensioner. Disengage the winch clutch and free spool some
cable off the drum. Adjust the air pressure to the cable tensioner to achieve the desired free spool
effort that also prevents "bird nesting" of the cable.
CAUTION: DO NOT EXCEED 80 PSI AIR PRESSURE TO THE AIR TENSIONER ACTUATORS.
Once you have adjusted the air pressure to the desired level, only minor adjustment may be required if
your pressure regulator setting drifts.

CAUTION: SYSTEM BACK PRESSURE MUST NOT EXCEED 50 PSI OR BRAKE SHAFT SEAL FAILURE

DRAIN LINE SHOULD BE RUN FROM THE MOTOR CASE DRAIN PORT (SEE PAGES 15-16) TO TANK OR
A LINE/CONNECTION THAT HAS A PRESSURE BELOW 50 PSI. THE DRAIN LINE MUST BE ROUTED SO
THAT SOMEWHERE ALONG ITS PATH, THE LINE IS HIGHER THAN THE MOTOR SHAFT CENTERLINE.
