Prior to installing the winch, carefully inspect it for possible
shipping damage.
Winches are supplied fully lubricated from the factory.
CAUTION
• Owners and users are advised to examine specific, local or
other regulations, including American National Standards
Institute and/or OSHA Regulations which may apply to a
particular type of use of this product before installing or
putting winch to use.
Mounting
1. Do not weld to any part of the winch.
2. The winch mounting surface must be flat and of sufficient
strength to handle the rated load plus the weight of the
winch and attached equipment. An inadequate foundation
may cause distortion or twisting of the winch end covers
and spacers resulting in winch damage.
3. Make sure the mounting surface is flat to within 1/32 inch
(0.8 mm). Shim if necessary.
4. Mounting bolts must be 3/8 in. (10 mm) diameter, Grade 8
or better. Use self-locking nuts or nuts with lockwashers.
5. Tighten mounting bolts evenly and torque to 50 ft. lbs. (68
Nm) for dry thread fasteners. If the fasteners are plated,
lubricated or a thread locking compound is used, torque to
35 ft. lbs. (47 Nm).
6. When a lead sheave is used, it must be aligned with the
center of the drum. The diameter of the lead sheave must be
at least 18 times the diameter of the wire rope.
7. Maintain a fleet angle between the lead sheave and winch
of no more than 1-1/2 degrees. The lead sheave must be on
a center line with the drum and, for every inch (25 mm) of
drum length, be a least 1.6 feet (0.5 m) from the drum.
