Pre-Install Checklist
1 Check to see that you have received the
following:
• The hoist
• The controller
• The remote control pendant
• The hoist mounting hardware
2 Upon removing hoist from packaging, check
for damage including bent or cracked tie rods,
tie bars, or housings. Correct any damage
before installing hoist.
3 Make sure the environment surrounding hoist
and controller is free of :
• Combustible vapors
• Chemical fumes
• Oil vapors
• Corrosive material
4 Make sure that the air temperature
surrounding the hoist and controller stays
within 120° F (49° C) and -20° F (-29° C).
5 Make sure that the mounting structure can
withstand the full rated pull of the hoist.
6 Make sure that the hoist boom or lift structure
will not deform under twice the full rated load
of the hoist.
WARN Industrial Hoists
Mounting the Hoist
Use the supplied fasteners whenever possible or
SAE Grade 5 (8.8 metric) bolts of the same thread
size. Both tie rods or tie bars must be in place.
Flat washers and lock washers should be used
between the bolt heads and mounting surface.
For thru bolt drum supports:
There should be 1 to 4 threads protruding
above the square nut. Bolts that are too long
may damage drum supports while bolts that are
too short will not provide adequate strength.
Flat washers and lock washers should be used
between bolt heads and mounting surface.
For threaded drum supports:
Bolts that are too long may damage the drum
supports and/or fail to anchor the hoist tightly.
Bolts that are too short will not provide adequate
strength. The length of the bolt must allow it to
extend between 15/16 inch (24 mm) and 1-3/8
inch (35 mm) into the base of the hoist.
1 Make sure that the mounting surface is flat
within +/-0.020 in. (0.50 mm). If the surface
is not flat, use shim stock as needed to avoid
straining the hoist.
2 Torque all mounting bolts to the recommended
values on the product data sheet.
3 Use the mounting hole locations provided on
the product data sheet.
