Ramsey Winch H-930r DOW-LOK w/Air Shifter for Grant Wrecker - Manual (Page 5)

TECHNIQUES OF OPERATION
The best way to get acquainted with how your winch operates is to make test runs before you actually use it. Plan your test in
advance. Remember, you hear your winch, as well as see it operate. Get 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.
The Dow-lok® clutch provides free spooling and clutch engagement with the cable drum. With the clutch disengaged, the cable
can be freespooled off the drum. For winching in the load, the clutch must be fully engaged with the drum.
TO DISENGAGE THE CLUTCH:
Run winch in the "out" direction until there is no load on the cable. Apply 70-90 psi to the air shift cylinder to disengage the
clutch. Do not disengage the clutch under load.
TO ENGAGE THE CLUTCH:
There must be a minimum of 1 foot of slack in the cable before attempting to engage the clutch. This will allow the drum to
rotate a minimum of 1/4 turn allowing engagement of the clutch before picking up the load. With this slack in the cable, exhaust
air pressure from the air shift cylinder and then run the winch in the "in" direction until the clutch springs into engagement and
the drum starts to turn. Clutch must be fully engaged before starting the winching operation.
WINCH MOUNTING
It is most important that this winch be mounted securely so that the three major sections (the clutch housing end, the cable
drum, and the gear housing end) are properly aligned.
This Model H-930 winch for Grant Wrecker is furnished with mounting angles. Angle size is 1/2” x 4 x 4 high strength steel
angle.
WINCH MAINTENANCE
Adhering to the following maintenance schedule will keep your winch in top condition and performing as it should with a mini-
mum of repair.
A. WEEKLY
1. Check the oil level and maintain it to the oil level plug with SAE 140 EP gear oil. 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 gases
may escape.
3. Lubricate cable with light oil.
B. MONTHLY
1. Lubricate the various grease fittings located in the cable drum, 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. Make sure it is spring loaded and free to move fully against the cable drum in the
engaged position and that it is pulled fully away from the cable drum and latched when disengaged.
3. Check the winch mounting bolts. If any are missing, replace them and securely tighten any that are loose. Use grade 5 or
better bolts.
4. Check the torque setting of the oil cooled worm brake. Make any adjustments required, following the procedure described
in Adjusting the Oil Cooled Worm Brake in this manual.
5. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.
