screw. If screw has been removed and replaced, always use new spots for locking.
On the 3 ton unit, hang it in the vertical position. Making sure there are no twists in the chain, feed the end of chain thru the hook block
G. Assemble the end ring
chain by rotating the last link 1/4 turn and passing the ends of the ring thru the link as shown below. Hammer or squeeze the ends of the ring together to secure it to the chain.
WARNING
CUTTING CHAIN CAN PRODUCE FLYING PARTICLES.
TO AVOID INJURY:
• WEAR EYE PROTECTION.
• PROVIDE A SHIELD, SUCH AS A HEAVY RAG, OVER THE CHAIN TO PREVENT FLYING PARTI- CLES.

CUTTING CHAINS
Hoistaloy® load chain is hardened for wear resistance and is difficult to cut. However, the following methods are recommended when cutting a length of new chain from stock or cutting off a length of worn chain.
(1) Use a grinder and nick the link on both sides, then secure the link in a vise and break off with a hammer.
(2) Use a 7 inch(177.8mm) minimum diameter by 1/8 inch (3.175mm) thick abrasive wheel (of type recommended by wheel supplier) that will clear adjacent links.
TESTING
Prior to initial use, all altered or repaired hoists or hoists that have not been operated for the previous 12 months must be tested by the user for proper operation.
Test the unit first in the unloaded state and then with a light load of 50 pounds (23kg.) times the number of load supporting strands of load chain to be sure it operates properly and the brake holds the load when the lever is released; then test with a load of *125% of rated capacity. In addition, hoists in which load sustaining parts have been replaced shall be tested with *125% of rated capacity by or under the direction of an appointed person and a written report prepared for record purposes.
*If unit is equipped with a Load Limiter, it may refuse to lift the 125% overload. Should this occur, reduce the test load to rated capacity. Also, on such units, the function of the Load Limiter should be checked. To do this attach the lower hook to a load of 180% of rated capacity and operate the unit in the “up” direction. When attempting to lift this load, the lever should slip. If it does not, the Load Limiter must be replaced. After this test, operate the unit in the “down” direction to remove tension in the chain.
NOTE: For additional information on inspection and testing, refer to the current issue of ASME B30.21 “Manually Lever Operated Hoists” obtainable from ASME Order Department, 22 Law Drive, Box 2300, Fairfield, NJ
