 CARE AND SERVICE OF YOUR HOIST
Your CHANCE hoist will give many years of satisfactory performance if used
and maintained properly. Always hang the hoist freely with a straight line
between the housing hook and the load hook. DO NOT JAM THE HOIST OR
P309-0359 STRAP AGAINST ANY OBJECT.
Rev. H
THE HOIST IS INTENDED FOR INDUSTRIAL OR UTILITY USE AND IS
NEVER TO BE USED FOR LIFTING PEOPLE OR LOADS OVER PEOPLE.

The CHANCE hoist is extremely easy to maintain. Years of life will be added
to the hoist by applying the following recommendations.

1. Do not use the hoist if it does not operate properly or is damaged in any
way.
2. Do not allow the strap to be pulled over any sharp edge or wrapped
around a pole or crossarm. Always use a sling or other means of attach-
ment.
3. Stop pulling before the load hook is pulled tight to the housing. Contin-
ued pulling into the housing may damage the hoist.
4. Never allow the handle to fly free or the hoist to self-ratchet.
5. Never throw or drop the hoist.
6. Keep the strap clean. Inspect the strap and hoist before each and every
use. Do not use a hoist if the strap is frayed, cut, or damaged.
7. All hoists must be periodically cleaned, inspected, and re-lubricated.
Intervals will depend on usage. The bronze bearings must be lubricated
with 30 wt. oil. All other moving parts must be lubricated with oil or film
of light grease.
8. Extra care must be used when lowering a light or "bouncing" load such as
a span of conductor. If the handle is "flipped", the hoist can self-ratchet
which causes severe wear on the dogs, ratchet teeth, and stop areas of
the hoist.
9. When operating the handle, do not "slam" the handle. A smooth, steady
pressure in each direction moves the load efficiently and does not cause
damage to the equipment.

DISASSEMBLY INSTRUCTIONS

! WARNING
Always wear safety glasses and other appropriate protective equipment
during the following procedures. Use the correct tools for the operations
being performed.
In order to best visualize these instructions, study and refer to the exploded
view of the hoist.
1. Remove snap ring (056011) from handle end shaft (P309-0259).
2. Push “Release Key” (P309-0346) in the indented area of the handle in the
direction marked “Release” to disengage the working pawl from the
unloader plate and lift handle (E309-0263) off the shaft. This will expose
the mechanism.
