TESTING

Before using, all altered, repaired or used hoists that have
not been operated for the previous 12 months shall 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 written
report prepared for record purposes.  After this test, check
that the Protector functions. If the Protector permits lift-
ing a load in excess of 200% of rated load, it should be
replaced.

NOTE: For additional information on inspection 

and testing, refer to American National 
Standard ASME B30.16 “Overhead Hoists” 
obtainable from The American Society of 
Mechanical Engineers, 345 East 47th Street, 
New York, NY  10017 U.S.A.

*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 correspon-
dence and orders for replacement parts:

1. Hoist rated load from identification plate.
2. Serial number of the hoist stamped below identifica-

tion plate.

3. Length of lift.
4. Key number of part from the parts list.
5. Number of parts required.
6. Part name from the parts list.
7. Part number from the parts list.

If trolley replacement parts are ordered, also include the
type and capacity of the trolley.

NOTE:   WHEN ORDERING REPLACEMENT PARTS, IT IS 

RECOMMENDED THAT CONSIDERATION BE 
GIVEN TO THE NEED FOR ALSO ORDERING 
SUCH ITEMS AS GASKETS, FASTENERS, INSU-
LATORS, SEALS, ETC. THESE ITEMS MAY BE 
DAMAGED OR LOST DURING DISASSEMBLY 
OR JUST UNFIT FOR FUTURE USE BECAUSE OF

WARNING

Cutting Chain Can Produce Flying Particles.

TO AVOID INJURY:

Wear Eye Protection

Provide A Shield Over Chain To Prevent Flying
Objects

!

WARNING

Using “commercial” or other manufacturer’s parts to
repair XL Air Hoists may cause load loss.

TO AVOID INJURY:

Use only factory supplied replacement parts. Parts may
look alike but factory original parts are made of spe-
cific materials or processed to achieve specific proper-
ties.

CUTTING CHAINS

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

below), then secure the link in a vise and break off
with a hammer.

2. Use a 7 inch ( 177 mm) minimum diameter by 1/8

inch ( 3.1 mm) thick abrasive wheel (or type recom-
mended by wheel supplier) that will clear adjacent
links.

3. Use a bolt cutter (See below) similar to the H.K.

Porter No. 0590MTC with special cutter jaws for cutting
hardened chain. Jaws should be 1 inch (25.4 mm) long.
