Periodically check tightness of
mounting bolts and electrical con-
nections. Remove any dirt or corro-
sion that may have accumulated on
the electrical connections.
Repair should be done by
Authorized Superwinch Repair
Centers ONLY. Do not attempt to
disassemble the gearbox.
Disassembly will void warranty.
LUBRICATION
The gearbox and drum bearing are
permanently lubricated with a high
performance gear lube. If relubrica-
tion is necessary (after repair or
disassembly) only use Shell Alvenia
EP2 or equivalent.
REPLACING THE WIRE ROPE
Figure 20
Never substitute a heavier or lighter
wire rope. Never use rope made of
any other material other than wire.
Always replace damaged wire
rope with manufacturer's identi-
cal replacement part (see
Replacement Parts list). Pass attach-
ing end of wire rope through the
fairlead (if equipped) and attach it
to the drum. When inserting the
wire rope into the drum, insert it
into the correct end of the hole
provided (Figure 20). Tighten the set
screw securely.
It is important that the wire rope be
wound tightly onto the drum. A
good way to do this is to attach the
wire rope hook to a load and winch
it in.

BRAKE OPERATION

Your SAC1000 winch has a wrap
spring brake that stops and holds
loads up to 1,000 lbs. (454 kg).
When powering the winch in, the
brake is disengaged and does not
become activated until the motor is
turned off and the load tries to pull
the wire rope off the drum. When
the winch is powered out, as in
releasing a load, the brake is
engaged and the motor must over
power the brake drag to rotate the
drum. Therefore, it is normal for the
winch to operate faster in one
direction than the other. The brake
is designed for the wire rope to be
used in the underwind position
only. DO NOT OVERWIND. Powering
against the brake will cause heat to
build up in the drum and may trans-
fer heat to the wire rope (Figure
21). DO NOT POWER OUT FOR
MORE THAN 50 FEET (15.2m) OR 2
MINUTES.
HOT!

get very hot.
When wire rope is removed from
the drum, as in bringing the hook
to the load, the freewheel feature
of the winch should be used.
The drum and
wire rope may
