V1.0
POWER
The maximum load the winch can
pull is diminished with each
additional layer of steel cable
around the winch' s drum. Table 1
shows the maximum amount of
weight it can pull and the length of
cable remaining on the drum.
Whenever possible, remove as much
steel cable off the winch to pull with
the maximum power. Keep five
wraps of steel cable on the drum at all times to prevent the steel cable from
slipping off.
Use a snatch block to move a heavier load that is close to the winch. This will
double the amount of line outside the winch and increase the winch' s pulling
power at close range.
LINE SPEED
The heavier the load, the longer it
will take the winch to move the load
to the desired location. Consult
Table 2 to determine how fast the
line will be drawn into the winch.
The winch requires more amps to
move a heavier load. Consult Table 2
to determine the amperage
consumption based on the load' s
weight. A snatch block will halve the
line speed when pulling the load.

POWER CONSUMPTION

A snatch block increases a winch' s pulling power without an increase in
amperage. Using a snatch block can halve the power required.
OPERATION ANGLES
The winch is the most efficient when towing in a straight line. However,
sometimes that is not possible. Change the angle using the fairlead or a pulley
when necessary.
The winch can retrieve or release the steel cable up to a:
• 15 degree vertical angle above or below the centerline.
