• 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 chain
guide/stripper (620-192).
• Retrace the new chain and check for twists. If chain is
twisted, start over.
IMPORTANT: Do not use “old” chain for other purposes
such as lifting or pulling. Load chain may break
suddenly without visual deformation. For this reason,
cut the “old” chain into short lengths to prevent use
after disposal.
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.
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 written report prepared for record
purposes. After this test, check that 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 stamped below identification
plate.
3. Voltage, Phase, Hertz from identification plate.
4. Length of lift.
5. Key number of part from parts list.
6. Number of parts required.
7. Part name from parts list.
8. 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.
Cutting chain can produce flying particles.
TO AVOID HEALTH PROBLEMS:
• Wear eye protection.
• Place a shield over chain to prevent flying objects.
Using “commercial” or other manufacturer’s parts to repair Prostar
Hoists may cause load loss.
TO AVOID INJURY:
Use only factory supplied replacement parts. Parts may look alike
but our parts are made of specific materials or processed to
achieve specific properties.
