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.
When pulling a load where there is even a remote chance of cable failure, place a blanket, jacket or
tarpaulin over the cable about six feet behind the hook. This will slow the snap back of a broken cable
and could prevent serious injury.
NOTE: The Ramsey level winder is an available accessory for tightly respooling unloaded cable
onto the drum.
The Ram-lok
hooking onto the load. The clutch is operated by the “T-handle”, located on the end of the winch as
follows:

semi-automatic clutch allows rapid unspooling of the cable, from cable drum, for
1. TO DISENGAGE CLUTCH, run the winch in the reverse (reel out) direction until the load is off the
cable. Pull outward on the clutch handle, rotate it counter-clockwise 90° and release. The clutch
is now locked out and the cable may be pulled off by hand.
2. TO ENGAGE CLUTCH, pull outward on the handle, rotate it counter-clockwise 90° and release.
Run the winch in reverse until the clutch handle snaps fully in or until the cable drum stops turning.
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 cable.
WARNINGS
CLUTCH MUST BE TOTALLY ENGAGED BEFORE STARTING THE WINCHING OPERATION.
DO NOT DISENGAGE CLUTCH UNDER LOAD.
DO NOT LEAVE CLUTCH ENGAGED WHEN WINCH IS NOT IN USE.
STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS.
STAND CLEAR OF CABLE WHILE PULLING. DO NOT TRY TO GUIDE CABLE.
DO NOT EXCEED MAXIMUM LINE PULL RATINGS SHOWN IN TABLE.
DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT PEOPLE.
A MINIMUM OF 5 WRAPS OF CABLE AROUND THE DRUM BARREL IS NECESSARY TO HOLD THE LOAD.
CABLE SETSCREW IS NOT DESIGNED TO HOLD 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 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 sliding clutch, making sure it is fully engaging and disengaging with the cable
drum. Remove the plastic plug in top of the housing and observe if the clutch is fully engaging. If
clutch is not fully engaging, inspect clutch shifter assembly parts, check for damage or excessive wear
and replace as necessary. Observe the jaws on both the clutch and cable drum, checking for rounding
of the driving faces. If rounding has occurred they should be replaced immediately.
3. Check the winch mounting bolts. If any are missing, replace them and securely tighten any that are
loose. Make sure to use only grade 5 bolts or better.
4. Inspect the cable. If the cable 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.
2. 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.
3. Refill the winch to the oil level plug with all purpose E.P. 140 gear oil.
4. Inspect frame and surrounding structure for cracks or deformation.
5. Gear wear can be estimated by rocking the drum back and forth and if necessary drain oil and
remove cover for closer inspection.
CABLE INSTALLATION
There are two tapered pockets cast into the drum. One pocket is for installations with the wire rope wound over
the drum. The other pocket is for an under-wound wire rope.
When properly used, the wedge pocket design is one of the most secure anchoring methods available.
1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of cable, opposite
hook, with plastic or similar tape to prevent fraying.
2. Slide the wire rope into the narrow end of the pocket against the drum flange.
3. Wrap the wire rope around the anchor “puck” and pull the wire rope and anchor back into the wide end of
the pocket.
4. Use a soft hammer to drive the back side of the wire rope, firmly seating the wire rope and anchor into the
pocket.
The wire rope can easily be removed from the drum by driving the anchor out the wide end of the pocket.

HYDRAULIC SYSTEMS
Refer to performance charts, below, to properly match your hydraulic system to the HDG-350 winch
performance. The charts consist of:
1. Line pull (lbs.) first layer vs. working pressure (P.S.I.). STATIC refers to lifting a suspended load
from rest; DYNAMIC refers to maintaining the motion of a moving load.
2. Line speed, first layer (F.P.M.) vs. gallons per minute (G.P.M.).
Performance based on a motor displacement of 4.5 cubic inches with 15 GPM maximum flow rate.
