CUTTING CHAIN
Hoistaloy ® load chain is hardened and it is difficult to cut.
The following methods are recommended when cutting a
length of new chain from stock or cutting off worn chain.
Always wear eye protection when cutting chain.
1. Use a grinder and nick
the link on both sides
(see right), then secure
the link in a vise and
break off with a
hammer.
2. Use a 7”(177 mm) minimum diameter by 1/8" (3.1 mm)
thick abrasive wheel (or type recommended by wheel
supplier) that will clear adjacent links.
3. Use a bolt cutter (see
right) with special cutter
jaws for cutting hardened
chain. Jaws should be 1
inch (25.4 mm) long.
Cutting chain can produce flying particles.
TO AVOID HEALTH PROBLEMS:
• Wear eye protection.
• Place a shield over chain to prevent flying objects.
TESTING
Before using, all altered, repaired or used hoists that have
not been operated for the previous 12 months must be
tested by the user for proper operation. First, test the unit
without a load and then with a light load of 50 pounds (23
kg) times the number of load supporting parts of load
chain to be sure that the hoist operates properly and that
the brake holds the load when control is released. Next test
with a load of *125% of rated capacity. In addition hoists in
which load sustaining parts have been replaced should be
tested with *125% of rated capacity by or under the
direction of an appointed person and a written report
prepared for record purposes. After this test, check the
Protector™ functions. If the Protector™ permits lifting a
load in excess of 200% of rated load, it should be
replaced.
*If the Protector™ prevents lifting of a load of 125% of
rated capacity, reduce load to rated capacity.

ORDERING INSTRUCTIONS
The following information must accompany all
correspondence and orders for replacement parts:
1. Hoist rated load from identification plate.
2. Serial number of the hoist from identification plate.
3. Length of lift.
4. Key number of part from parts list.
5. Number of parts required.
6. Part name from parts list.
7. Part number from the parts list.
NOTE: When ordering replacement parts, it is recom-
mended that consideration be given to the need for
also ordering such items as gaskets, fasteners, seals,
etc. These items may be damaged or lost during
disassembly or just unfit for future use because of
deterioration from age or service.
Using “commercial” or other manufacturer’s parts to repair the
ShopAir Hoist may cause load loss.
TO AVOID INJURY:
Use only factory supplied replacement parts. Parts may look alike
but factory original parts are made of specific materials or
processed to achieve specific properties.

5. On the 250, 300 and 500# (Single Reeved) (113, 136
and 226 kg.) units, remove the hook block from the old
chain and attach it to the new chain by reusing the
chain pin (620-158).
On the 500, 600 and 1000# (226, 272 and 453 kg.)
units:
•
Remove dead end plate (620-160) from hoist.
• Remove dead end pin (620-161) from the last link
of chain and pull chain out of dead end plate.
• Pull old chain out of hook block and disassemble
the hook block.
• Make sure the new chain is not twisted and wrap
the chain around the sheave wheel (620-162) with
welds down and towards the sheave wheel.
• Reassemble hook block and pull the new chain
through the hook block.
• Slide the dead end plate over the last link and
secure it using the dead end pin.
• Making sure the chain is not twisted between the
hook block and hoist, attach the dead end plate to
the stripper (620-143).
• Retrace the new chain and check for twists. If
chain is twisted, start over.
