5.0 OPERATING PROCEDURE
IT IS IMPERATIVE THAT ALL PERSONS USING, OPERATING OR MAINTAINING
THIS WINCH BE FULLY TRAINED AND COMPETENT TO DO SO, AND HAVE
READ THE ENTIRE OPERATING MANUAL.
GMP CANNOT BE HELD RESPONSIBLE FOR MIS-USE OF THIS EQUIPMENT.
5.1 CONTROLS
The operator controls have been designed to be safe and simple to use, with regard to
ergonomic considerations. The operators control station is complete with the following:
(see section 8)
(a) Control lever for winching in and paying out. This provides bi-directional selection of
capstan rotation. The valve spool has a soft start facility allowing for a limited creep
and inching movement.
(b) Control lever for operation of the rear take-up drum. This lever should be in its oper-
ating position before operating the capstan. If the winch is not being used, this lever
should be returned to its non-operating position, thus saving on fuel and preventing
the hydraulic oil from overheating.
(c) Tension control knob. This can be used to limit the actual pulling tension applied to
the capstan.
(d) Pressure gauge which is also an indication of the pulling tension.
5.2 PRE-WINCHING PROCEDURE
 Prior to using the winch for any hauling application, it is important to ensure that the
rear prop legs are extended and lowered in order to level the winch, and that the
front jockey wheel is also lowered to a position where the winch is firm and stable.
The winch should be securely anchored to either a suitable vehicle, ground anchors
or other substantial holding point. The winch should be in line with the direction of
pull.
 Refer to the pre-winching maintenance checks in section 6.1.
 The capstan must be rotated from the “Transverse” transit position to the In-Line
working position. Ensure that the retaining pin and hair-pin are correctly replaced.
It may be necessary to remove the lighting board. This is accomplished by first
un-plugging the connector from the rear jack on the trailer, and then pulling the
spring loaded release pins. The complete lighting board can then be removed
and stored safely.
