1. An emergency crank handle is provided for use in

the event of a power failure. Remove the electrical

power from the winch.

WARNING: NEVER OPERATE THE WINCH ELEC-

TRICALLY WITH THE EMERGENCY HANDLE IN

POSITION.

2. Remove the plastic plug from the side of the winch

housing and insert the handle so that it completely

engages with the drive shaft. The handle can be

cranked in either direction with the clutch in the

engaged position. To make cranking easier, the

clutch can be placed in the free wheel position while

holding onto the emergency handle.

WARNING: IF THE CLUTCH IS PLACED IN FREE

WHEEL FOR HAND CRANKING, BE SURE TO

MAINTAIN A FIRM GRIP ON THE HANDLE AT

ALL TIMES.

Because the emergency crank handle for models

SA9000AC and SA12000AC attaches to the clutch side

of the winch, it is equipped with a spring operated clip

which will be depressed by the clutch handle in the free

wheel position when cranking in a clockwise direction to

retrieve the cable. This clip is a safety feature and will re-

engage the clutch mechanism in the event that the oper-

ator loses control of the handle with a load on the winch.

(See FIG. 4)

WARNING: EVEN WITH THIS SAFETY FEATURE

THE HANDLE WILL STILL SPIN VIOLENTLY ONE

OR TWO TURNS BEFORE RE-ENGAGING THE

CLUTCH TO STOP THE WINCH. DO NOT LOSE

CONTROL.

3. Always remove the handle from the winch after use

and replace the plastic plug.

For long life and trouble-free operation your winch

should periodically be inspected for any required main-

tenance. This should be done at least once annually and

more frequently in adverse conditions such as salt water

areas or areas of extreme dust and dirt.

1. Carefully inspect the winch cable for any kinks, frays

or abnormal stiffness and replace at the first sign of

this kind of damage. Periodic lubrication with a light

oil will improve the life of the cable. In order to

replace the winch cable, it is necessary to remove

the clutch handle, by removing the two clutch

handle screws, and the four cover mounting bolts.

Be sure that the power is disconnected from the

housing and lift the housing off of the winch by

gently stretching it open near the lower front corner.

Rotate the winch reel so that you have access to the

rope clamp. Remove the old cable and replace it

with a new cable of the same size. Be sure that the

cable passes under both sides of the rope clamp

and that the clamp is tightened securely.

NOTE: CABLE IS WOUND OVER THE TOP OF

THE DRUM ON MODELS SA5000AC AND

SA7000AC AND UNDER THE DRUM ON MODELS

SA9000AC AND SA12000AC. SEE ATTACHMENT

METHOD BELOW (FIG. 5).

2. With the cover removed as described above, inspect

the entire gear train and all drive shafts for any sig-

nificant wear or loose bearing fits. Grease all of the

gears on the inside of the winch base and apply a

drop of oil on all of the bearings in the base. Also,

very sparingly oil all of the bearings in the clutch

mechanism and place a drop of oil on the roller

clutch. Do not over lubricate these areas and do not

use grease in the roller clutch. The clutch mecha-

nism and the brake pads and brake disc must be

kept clean and oil free.

3. Check the operation of the roller clutch. Carefully

rotate the brake disc and observe the motor shaft.

When the disc is turned clockwise the motor shaft

should turn with it. When the disc is turned counter-

clockwise the motor shaft should not turn. Also,

check all nuts, bolts, retaining rings, etc., to be sure

that they are tight and secure.

4. If the clutch has been slipping and requires adjust-

ment the following procedures should be used. The

clutch is adjustable in ten degree increments. With a

screwdriver and pliers, remove the end of the clutch

spring from the hole in the winch base. The spring

tension is quite high so be careful to maintain a firm

grip on the spring. The O-ring should be rotated so

that the cut out portions align with the lugs on the

spring keeper. (See FIG. 6)

The ring can then be expanded with a pencil or simi-

lar object and the spring keeper can be lifted free

from the clutch nut. Rotate the keeper clockwise 10

degrees and install on the next serration in the

clutch nut. Reinstall O-ring and rotate slightly so that

the cut outs are not in line with the lugs on the

spring keeper and reinstall the clutch spring into the

hole in the base. Adjustment of the clutch more than

10 degrees to 20 degrees should normally not be

necessary. With only spring pressure (do not forcibly
