Pre-winching procedure
Prior to using the winch for any hauling application, it is important to
ensure that the rear prop legs are lowered in order to level the winch,
and that the front prop stand / 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.
Check the hydraulic oil level, engine oil level and engine fuel level.

Setting maximum line tension
This needs to be carried out with rope available on the take-up drum.
a)
Attach the free end of the rope to the fixed hook situated below the rear
bullwheel.
b)
Pass the rope over the rear guide roller, over the rear bullwheel and then
over the front bullwheel to occupy the first groove nearest the gearbox.
c)
Pull the rope tight and pass it under the front bullwheel and back under the
rear bullwheel, occupying the first groove nearest to the gearbox.
d)
Pass the rope over the bullwheel and continue threading the rope around
each groove on both bullwheels in turn until the bullwheel grooves are fully
occupied.
e)
The rope should pass from the last groove on the rear bullwheel, over the
layering arm and onto the take-up drum.
f)
Rotate the rope take-up drum until there is minimum slack in the rope from
the bullwheels to the drum and then re-engage the drum drive.
g)
Start the engine. Refer to the engine manufacturers manual supplied with
the engine.
h)
Operate the drum control lever to engage the drum drive. The rope should
tighten up between the bullwheels and the take-up drum.
i)
Operate the control lever to winch in. The rope will tighten up between the
bullwheels and the rope hook securing the free end. The bullwheels will
stop rotating at the selected tension. This tension can now be adjusted by
rotating the tension adjustment knob clockwise to increase and counter-
clockwise to decrease the tension.
j)
The maximum pulling tension is now set. Operate the winch control lever to
winch out. This will help release the tension in the rope. Reset the drum
control lever to its non-operating position. The rope may now be removed
from the fixed hook and from around the bullwheels if required.
