Anchoring the winch
OPTION 1 : In most cases, the winch is anchored to a fixed object
using a polyester sling or one of our optional anchors and the line
is attached to the object you are trying to move. The latter is moved
towards the winch as the winch pulls the line.
OPTION 2 : Sometimes, the winch can be anchored to the object
you want to move and the line is attached to a fixed object. The
winch and the object being moved are then pulled towards the line's
anchoring point. This method is useful when you guide the load
while operating the winch.

To anchor the winch, wind it around the anchoring point with the
sling. Insert the sling in each of the two safety hooks located on the
back of the winch (fig. 1).
Place the winch in the direction of the load to be pulled. When the
winch is switched on, it will attempt to align itself with the load. The
friction of the sling against the anchor may prevent correct
alignment; in this case, release the tension in the line and move the
sling so that the tension is distributed over the two hooks equally.

You must attach the load to the end of
the line. Although a simple knot may
sometimes suffice, we recommend
using a bowline knot (fig. 1). This knot
holds approximately 70% of the line's
capacity while most knots reduce the
line's capacity by 50% or more.
Additionally, it may be easy to untie
even after pulling a heavy load.
Even better, a double bowline knot (fig.
2) allows you to maintain approx. 75%
of the line's capacity.

Oil level
The Honda GXH-50 engine is fitted with an Oil Alert
automatically shuts off the ignition when the oil level in the
crankcase falls below a safe level.
The Oil Alert
TM
system also stops the engine when the engine's operating
angle exceeds 20 degrees (± 4 degrees). Make sure that your installation
keeps the winch relatively horizontal during pulling and when idling.
If the oil level exceeds the maximum level, there could be an
excessive amount of contaminants such as unburned fuel and
condensed water vapor. Drain and change the oil.

Installing the rope
sling.
The wide range of situations encountered during pulling prevents
us from giving specific instructions for all situations; however, you
should consider the following points:
3.4.1
Rope
Use a line with a low elasticity in good condition with a minimum
diameter of 10 mm and a maximum diameter of 13 mm with good
knots. We highly recommend the bowline knot (see section 3.1.3).
Use pulleys to divert the line and increase the pulling power when
the load approaches or exceeds the winch's pulling capacity.
3.4.2
Pulley
The use of a pulley at a short-distance from the winch offers several
benefits:
● Provides an angle allowing the load to be slightly raised to reduce
friction;
● Maintains the winch in near horizontal position;
● Keeps the winch and the operator away from the load's trajectory.
3.4.3
Direction
Install the line so that it doesn't rub against any objects during
pulling. Try to install the line so that the front of the load is slightly
raised. Never pull downwards or through obstacles.

Pulling a load
WHAT NOT TO DO: WHEN YOU INSTALL
THE SLING TO ANCHOR THE WINCH,
AVOID A FULL TURN AROUND AN
ANCHORING POINT (FIG, 2). THIS WILL
PREVENT THE WINCH FROM ALIGNING ITSELF WITH THE
LOAD CORRECTLY. THIS WILL ALSO APPLY UNEVEN
TENSION TO EACH OF THE HOOKS.
AVOID INSTALLING THE SLING ON SHARP CORNERS WHICH
ARE LIKELY TO DAMAGE THE POLYESTER SLING. WHEN YOU
USE A POLE, A TREE OR A STUMP AS AN ANCHORING
POINT, INSTALL THE SLING CLOSE TO THE BASE.
ANCHORING AROUND A STUMP REQUIRES SPECIAL
ATTENTION TO AVOID THE SLING SLIPPING OFF THE TOP
OF THE STUMP.
ENSURE THAT THE ANCHORING POINT IS ABLE TO
WITHSTAND THE WINCHING WITHOUT BREAKING, BEING
EXTRACTED OR BECOMING DAMAGED.

THE CORRECT DIRECTION WHEN DEPLOYING THE LINE
IS THE KEY TO THE SAFE USE OF THE WINCH.
IN GENERAL, IF THE LINE TOUCHES THE GROUND
DURING PULLING THEN THE SETUP IS INCORRECT.
DO NOT PULL A LOAD DOWN A SLOPE TOWARDS THE
WINCH BECAUSE THE LOAD MAY SLIDE TOWARDS YOU
BEFORE YOU CAN STOP IT. IN THIS CASE, USE A PULLEY AT
THE BOTTOM OF THE SLOPE AND POSITION THE WINCH
FURTHER BACK AWAY FROM THE AXIS OF THE LOAD.
CHECK THE POSITION OF THE WINCH, THE STATE OF THE
LINE, THE STRENGTH OF THE ANCHORING POINT,
KNOTS, HOOKS AND/OR SHACKLES TO AVOID INJURIES
AND MATERIAL DAMAGE.
