TO ENGAGE CLUTCH
Raise the handle so the notch clears the
bracket, and pull handle out as far as it will
go. The clutch will automatically spring into
engagement and latch when the clutch
aligns with the drum shaft. In order to attain
full engagement, internal elements of the
clutch MUST be aligned. This alignment will
take place when rope drum or rope drum
shaft turns a maximum of 1/4 revolution.
Do not attempt to pull a load unless notch in
shifter shaft is securely latched. Keep clear
of spring-loaded handle during automatic
engagement.
TO DISENGAGE CLUTCH
Raise handle so notch clears bracket.
Push handle in and latch the shaft notch
onto bracket. Do not disengage the clutch
under load.
WINCH 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 in top of the
gear housing. Be sure that it is in good
operating condition so that hot oil gasses
may escape.
3. Lubricate rope with light oil.
B. MONTHLY
1. Lubricate the various grease fittings
located in the ends of rope drum shaft, end
bearing, clutch housing or clutch operating
linkage. Any good grade of moly-disulfide
containing grease is acceptable.
2. Check the action of the locking ring,
making sure it is spring loaded and free to
move fully against the rope drum in the
engaged position and that it is pulled fully
away from the rope drum and latched
when disengaged.
3. Check the winch mounting bolts. If any are
missing, replace them and securely tighten
any that are loose to recommended
torque. Make sure to use only grade
5 bolts or better.
4. Check the torque setting of the oil cooled
holding brake. Make any adjustments
required, following the procedure
described in ADJUSTING THE OIL
COOLED HOLDING BRAKE in the
Owner's Manual.
5. Inspect the rope. If the rope has become
frayed with broken strands, replace
immediately.
C. ANNUALLY
1. Drain the oil from the winch annually or
more often if winch is used frequently.
Fill the winch to the oil level plug with clean
kerosene. Run the winch a few minutes
with no load in the reel in direction.
Drain the kerosene from the winch.
Refill the winch to the oil level plug with all
purpose E.P. 140 gear oil.
2. Inspect frame and surrounding structure
for cracks or deformation. Gear wear can
be estimated by
rocking the drum back
and forth and if necessary drain oil and
remove cover for closer inspection.
3. Adjust the oil cooled holding brake. See
ADJUSTING THE OIL COOLED
HOLDING BRAKE
on page 7.
