To control the drum speed in free spool:
For winches with a disc type drag brake, pull the single clutch control lever all the
way out and hold according to the amount of braking required.
For winches with a band or caliper type drag brake, actuate the separate control
lever and hold according to the amount of braking required.
Shifting - when shifting the clutch, the long practiced standard method of using
mechanical controls actuated manually, allows the operator to obtain a combined
feel for rotational speed and thrust. This procedure avoids damage caused by the
unnecessary clashing of clutch components and enhances greater winch life expec-
tancy.
Conversely, there are many shifting requirements that are satisfied through the use
of automatic controls such as hydraulic, pneumatic or electric. For these applica-
tions, it is important to keep in mind that when actuating this type of control, a
complete action takes place and the ability to feel is lost. Unless properly designed
and carefully operated, the sudden thrust attempt to engage the clutch when not
necessarily in the correct position could prove to be detrimental to component life.
When finished with the winch, pass the wire rope through the tail shelf sheave and
hook into a fixed section of the chassis frame. A slight tension can thus be main-
tained in the wire rope, preventing entanglement on the drum.
MAINTENANCE Inspection of the winch and related components should be a continuing procedure.
The operator should be constantly alert to detect unusual noises, excessive oil leak-
age and overheating. He should report immediately any changes in the normal char-
acteristics of the winch, winch accessory or the hydraulic system.
Oil levels, oil cups, grease fittings and chain adjustments should be checked after
each seventy-five hours of operation.
If the winch has not been used for an extended period of time, the interior should be
inspected for water deposits and rust due to the elements or condensation. Particu-
lar attention should be given to any damaged bearings, seals or gaskets. The oil
should be checked for contamination, abrasive foreign particles and lubrication
qualities. As required, oil should be added or completely drained and filled.
The wire rope should be inspected visually for kinks, bends, cuts or broken strands
while operating.
Depending on the total length of the wire rope vs. the length most often used, it is
possible that the top lays will show the most wear. To obtain additional life, subject
to the proper conditions, the rope can be rotated end to end.
The hydraulic system should be checked periodically for:
Overheating
Abnormal noise
Maintain a clean sufficient quantity of hydraulic oil of the proper grade.
Keeping all connections sufficiently tight to prevent oil leakage and air from enter-
ing the system.
Change the oil filter periodically.
LUBRICATION The winch has two reservoirs that must be checked and maintained.
Automatic Brake Housing
To check for the proper oil level, remove the oil level plug in the side of the hous-
ing. The lubricant should be maintained to the height of the oil level opening.
To add oil, remove the oil level plug in the side of the housing. Remove the oil
filler plug in the housing cover. Add type "A" automatic transmission fluid as re-
quired to the height of the oil level opening.
