Maintenance (continued)
If rounding has occurred they should be replaced immediate-
ly.Spool the rope properly on the drum when storing between
each usage. Check the oil level in the gearboxes every six
months. At the same time, check electrical connections and
mounting bolts – tighten if necessary.
Corrosion on electrical connections will reduce performance
or may cause a short. Clean all connections, especially in
remote switch receptacle. In salty environments use a sili-
cone sealer to protect from corrosion.
Replace oil annually or more often if winch is used frequently.
Fill the worm gear box with 3/4 pint of SAE 140 EP. Use 1/2
pint of SAE 20 for spur gear box. Apply cup grease to lube
fitting at top of clutch housing. Should winch be submerged
for a brief period, drain oil, flush and replace oil in gearboxes,
and grease all fittings (see Troubleshooting Guide).
To minimize corrosion of the internal motor components that
may occur due to condensation, power the winch in or out
periodically. Energizing the motor will generate heat, which
will dissipate any moisture buildup in the motor. This should
be performed at periodic intervals (such as with each oil
change to your vehicle).
Lubricate rope periodically using light penetrating oil. Inspect
for broken strands and replace if necessary. Install new rope
per “Rope Installation”, Page 2.
Operating Instructions
The RAM-LOK® semi-automatic clutch provides free spool-
ing and clutch engagement with the rope drum. With the
clutch disengaged, the rope can be pulled off the drum by
hand. For winching in the load, the clutch must be fully
engaged with the drum.
To disengage the clutch:
run the winch in the reverse
(“reel-out”) direction until the load is off the rope and the rope
drum stops turning. Pull outward on the clutch handle, rotate it
counter-clockwise 90º and release. The clutch is now locked
out and the rope may be pulled by hand. (NOTE: If the clutch
handle cannot be pulled out, again run the winch momentarily
in reverse to relieve pressure on the clutch jaws.)
WARNING:
DO NOT ATTEMPT TO DISENGAGE THE ROPE DRUM WHEN
THERE IS A LOAD ON THE ROPE.
To engage the clutch:
pull outward on the handle, rotate it
clockwise 90º and release. Run the winch in reverse until the
clutch handle snaps fully in or until the rope drum starts turn-
ing. At this point make sure the clutch handle is all the way
in. The plastic plug in top of clutch housing may be removed,
for inspection of clutch to assure total engagement. After the
clutch is fully engaged, the winch is ready for winching in the
rope.
Adjustment of Rated Load Limiter
1. Make some test pulls with winch (using a load cell or
spring scale) to determine if switch is at desired rated
load setting. Acceptable setting is 100% to 125% of
rated load.
2. If load is not within above range, remove tamper-proof
compound in threaded hole (on top of set screws #75
& 76).
Remove top set screw.
3. Loosen bottom set screw approximately 2 turns
counter
clockwise.
4. To reduce line pull, thread switch #72 “IN” by turning
clockwise. To increase line pull, thread switch “OUT”.
5. After desired setting is reached, tighten bottom set
screw securely.
6. Re-install top set screw and tighten securely. Fill
threaded hole with a potting-type compound which must
be removed before any future adjustment is made.
End of Service Measures
When winch reaches the end of its serviceable life, dispose
of per local environmental regulations
