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® semi-automatic clutch
allows rapid unspooling of the cable, from
cable drum, for hooking onto the load. The
clutch on the winch is operated as follows:

1. TO DISENGAGE CLUTCH,

run the winch
in the reverse (reel out)direction until the
load is off the cable. Lift up knob and
pull out, lock in place. See warning label
located by shifter knob. The clutch is
now locked out and the cable may be
pulled off by hand.

2. TO ENGAGE CLUTCH,

lift up knob then
release. See warning label located by
shifter knob. Run the winch in reverse
until the shifter knob snaps fully in or
until the cable drum starts turning. At
this point make sure the shifter knob 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.

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 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 moly­disulfide containing grease is accept­able.

2. Check the action of the sliding
clutch—ensure it is fully engaging
and disengaging with the cable drum.
To observe if the clutch is fully
engaging, remove the plastic plug in
top of the housing. 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 SAE grade 5
bolts or better.

4. Check alignment of chain and sprock­ets and adjust as required to minimize
wear.

5. 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

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. Insert the end of cable, opposite hook
end, into the 1/2" dia. hole in drum bar­rel. Secure cable to drum barrel, using
setscrew furnished with winch. TIGHTEN
SETSCREW SECURELY.

3. Carefully run winch in the "reel-in" direc­tion. Keeping tension on end of cable,
spool all the cable onto the cable drum,
taking care to form neatly wrapped lay­ers.

WORM BRAKE MAINTENANCE

BRAKE ADJUSTMENT

The oil cooled, fully adjustable, automatic
safety brake operates in the worm housing
lubricant, all parts being submerged in oil.
When the brake wears to the point that the
load begins to drift, the brake can be adjust­ed as follows:

1. Loosen the lock nut on the adjusting
screw.

2. Tighten the brake by turning the adjusting
screw clockwise. CAUTION: Only 1/4
turn is usually required to adjust the
brake. Over-tightening can cause over­heating, and damage to the brake parts.
Tighten the lock nut after adjustment is
completed.

If the brake does not respond to adjustment
then a new leaf spring and brake disc is
needed.

A torque wrench can be equipped with a
special adapter to fit the input shaft (worm)
of the winch. The adapter can be made by
welding a nut to the end of a piece of tubing
as shown in the figure at right.

After welding the cap and nut to the tubing,
slot the tubing, as shown. This will allow the
special adapter to slide over the key­way and will then act as a large
socket. A torque wrench can the be
used to apply the proper torque.

Turn the torque wrench so that the
drum turns in the spool out direction
or lowering direction. The torque rat­ing for the Model HDG-350 should be
9-15 ft-lbs. (15-20 Nm), If torque
wrench does not show the proper
value as it turns, then the worm
brake adjusting bolt should be turned
clockwise 1/4 turn. Each time the adjusting
bolt is turned, checked the torque reading.
Continue this procedure until the proper

torque reading is

achieved. Then tighten the

lock nut.

SERVICING THE BRAKE

Refer to the Worm Brake Diagram on the fol­lowing page while following these instruc­tions.

1. Back off the lock nut, then the adjusting
screw, both two turns or more by turning
them counter-clockwise.

2. Remove the cover mounting screws.

3. Remove the cover along with coil spring
and leaf spring.

4. Remove the retainer plate, composition
brake disc, cam plate and balls. Note
which slots balls are in.

5. Inspect par ts as follows:

a) Composition brake discs are 1/8" thick

when new. Replace if thinner than

0.080” or if surfaces are glazed or
burnt.

b) Inspect the flat, ground surface of the

cam plate and retainer plate for glazing,
warpage, or other damage. Glazing
can be removed by scraping carefully.

c) Inspect the leaf spring. It should be

bowed 1/8".

3. Install retainer plate, smooth side toward
brake disc.

4. Install the gasket on the cover with a
small amount of grease or sealer.

5. The coil spring goes over the adjusting
screw on the inside of the cover.

6. Install the notches of the leaf spring on
the pins protruding through the cover.
The hollow side of the leaf spring goes
toward the brake.

7. Install brake housing cover, making sure
the protruding pins go through the leaf
spring and into the holes in the retainer
plate. Tighten capscrews to 7-8 ft-lbs.
(9-10 Nm) torque.

8. Bolt cover into place with the mounting
screws. Install drain plug and add 1 pint
of S.A.E. 140 EP oil.

9. Turn winch in the reel in direction at least
one turn of the input shaft.

10.Turn the adjusting screw in until it is fin­ger tight.

TEST FOR PROPER BRAKE ASSEMBLY

After the brake has been adjusted to the
proper torque setting disengage clutch. Start
vehicle engine and run winch in the reel in
(hoisting direction). Allow winch to run in
this direction for one minute.

Place your hand on the safety brake housing.
If housing is not hot to the touch then run
winch in the reverse direction (cable out) for
one minute. Brake housing should begin to
heat.

When these conditions exist, proper installa­tion has been made. If heating becomes
noticeable when running the winch in for­ward rotation (hoisting direction), the brake
should be again disassembled. When disas­sembled, place the brake balls in the alter­nate set of slots in the cam plates, then
carefully follow the instructions for re­assembling and checking the brake.

HYDRAULIC SYSTEMS

Refer to performance char ts, 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 (PSI). STATIC (solid line) refers
to hoisting a suspended load from rest; DYNAMIC (dashed line) refers to

LIMITED WARRANTY

RAMSEY WINCH warrants each new RAMSEY winch to be free from defects
in material and workmanship for a period of one (1) year from date of pur­chase.

The obligation under this warranty, statutory or otherwise, is limited to the
replacement or repair at the Manufacturer's factory, or at a point designated
by the Manufacturer, of such part that shall appear to the Manufacturer,
upon inspection of such part, to have been defective in material or work­manship.

This warranty does not obligate RAMSEY WINCH to bear the cost of labor
or transportation charges in connection with the replacement or repair of
defective parts, nor shall it apply to a product upon which repair or alter­ations have been made, unless authorized by Manufacturer, or for equip­ment misused, neglected or which has not been installed correctly.

RAMSEY WINCH shall in no event be liable for special or consequential
damages. RAMSEY WINCH makes no warranty in respect to accessories
such as being subject to the warranties of their respective manufacturers.

RAMSEY WINCH, whose policy is one of continuous improvement, reserves
the right to improve its products through changes in design or materials as
it may deem desirable without being obligated to incorporate such changes
in products of prior manufacture.

If field service at the request of the Buyer is rendered and the fault is found
not to be with RAMSEY WINCH's product, the Buyer shall pay the time and
expense to the field representative. Bills for service, labor or other expenses
that have been incurred by the Buyer without approval or authorization by
RAMSEY WINCH will not be accepted

See warranty card for details.
