COLD WEATHER OPERATION
When operating the hoist in cold
weather, test the secondary overspeed
brake frequently.
Make sure it is not frozen. If the
brake does not stop the hoist, DO NOT
USE the hoist until the brake has been
thawed, dried, and is in proper working
condition.
Thaw out the brake by blowing ducted
dry heat (150°F / 65.6°C max) on the
brake area. This can be done with an
ordinary hair dryer.
DO NOT USE open flame on the unit.
If the unit will not operate properly
after thawing, DO NOT USE. If the
hoist will not climb or descend during
these tests, do not use the hoist unless
this is corrected during the thaw out
process.
Return the hoist to your hoist supplier.
WARNING
Be extremely careful when using the hoist
in freezing temperatures. Frequently check
for normal hoist operation. All tests must
be done within 3 ft (.9m) of ground level.
REMOVING THE MAIN
SUSPENSION WIRE ROPE
Make sure that the platform is properly
supported on a stable surface before
putting slack on the main suspension wire
rope to prevent hoists and platform from
tipping and causing injury.
While on the ground, the main
suspension line will wind out of the hoist
when the ↓ DOWN control button is
pushed.
You may have to help remove the last
15” (38 cm) of wire rope.
Grab the wire rope above the rope
insertion point, hold the Overspeed brake
reset knob in the “reset” position, and
slowly pull the main suspension wire rope
out of the hoist.
