4. Hold cam adjustment screw in position and tighten screw. Do not over tighten.
5. Reset the control valve to allow air supply to flow back into the motor. Refer to
“Emergency Stop and Reset,” p.
.
6. Repeat steps 1 through 5 operations for the second cam.
7. Test the winch set points by operating winch through three complete cycles to make sure the limits are within
+/- 0.5 m of set points.
8. Once settings are at the desired limits close the access cover (278) and tighten capscrews (86). Do not over
tighten capscrews.

Activate the shut off valve and operate the winch in opposite direction at slow speed during one
turn when a top or bottom limit switch is actuated.
Motor
For optimum performance and maximum durability of parts, provide an air supply of 70 to 100 psig (5 to 7 bar) at
the flow recommended in
, as measured at the motor inlet. The winch should be installed as
near as possible to the compressor or air receiver.
Press Roller
Make sure the wire rope is positioned between press roller and drum barrel and spring frame, to keep press roller in
tight contact with wire rope.
Pendent
Check that all hose connections are tight and that hoses are not twisted or crimped.
Refer to
Pendent lengths up to 66 ft (20 m) are available. Contact the factory for pendent lengths greater than 66 ft (20 m).

To avoid damaging the pendent hose, make sure the strain relief cable, not the pendent hose, is
supporting the weight of the pendent.
Initial Winch Operating Checks
Winches are tested for proper operation prior to leaving the factory. Before the winch is placed into service the
following initial operating checks should be performed.
1. When first running the motor inject a small amount of light oil into the main inlet connection to provide initial
lubrication.
2. Operate the winch in both directions with no load for a few minutes.
3. Check operation of limit switches, locking mechanisms and all safety devices when equipped.
4. Check foundation mounting fasteners are secure.
5. Check wire rope does not come in contact with the guard.
For winches that have been in storage, the following start-up procedures are required:
1. Give the winch an inspection conforming to requirements of
“Winches Not in Regular Use,” p. 17
.
2. Check oil levels in reduction gear and disc brake, top off levels as required.
3. Pour a small amount of ISO VG32 (SAE 10w) oil in motor inlet port.
4. Operate motor for 15 seconds in both directions to flush out any impurities.
5. The winch is now ready for normal use.
