Ramsey Winch H-930R DOW-LOK w/Air Shifter for Szummar - 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.
AIR SYSTEM REQUIREMENTS
The cable tensioner requires an independent, adjustable regulated air supply of between 50 and 90 PSI. An air regulator kit,
Ramsey Part No. 256092 is recommended.
CAUTION: DO NOT EXCEED 100 PSI TO THE CABLE TENSIONER ACTUATORS. THIS COULD CAUSE DAMAGE
TO THE ACTUATORS.
The inlet port of the air cylinder clutch requires a separate regulated air supply of 70-90 PSI.
CABLE TENSIONER OPERATION
If you remove the cable entirely from the winch or this is a new installation: The cable tensioner is not
intended to be energized on a bare drum. Before applying air to the cable tensioner, install the cable.
To adjust the free spool effort of the cable tensioner: Disengage the winch clutch and freespool 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.
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 is furnished with mounting angles. Angle size is 1/2” x 4 x 4 high strength steel angle.
