SAFETY PRECAUTIONS
ALWAYS:
1. Inspect the general condition of the chain block and chains for signs of damage or
wear before placing into storage.
2. Check that the load hook will reach its lowest point without running the chain fully
out.
3. Ensure that the suspension point is strong enough to take the weight of the chain
block and its load.
4. Check the travel path is clear and that you have a clear view to avoid any
obstructions.
5. Wear industrial gloves when operating the chain block.
6. Wear a hard hat, safety shoes and safety goggles when operating the chain block.
NEVER:
1. Lift a load exceeding the rated capacity stated on the chain block.
2. Use the chain block when the chain is kinked.
3. Stand beneath a raised load.
4. Use the chain block if it requires more than ordinary effort to operate it.
5. Throw, drop or drag the chain block.
6. Use undue effort to force the block to operate.
7. Allow oil or grease to come into contact with the brake.
8. Lift loads at an angle or use for towing. Only lift loads vertically.
9. Never replace the load chain with a non-approved chain.
BEFORE LIFTING
1. Careful inspection should be made to the parts such as hook, load chain, braking
device, etc. and the lubrication of the block. The chain block can only be put into
operation when it is found to be in good condition.
2. Judge the weight of the load to be lifted and make sure the chain block is suitably
rated. Never overload the block.
3. Attach the chain block to the suspension point.
• The suspension point must be able to support the weight of the load and the
chain block.
4. Attach the load hook directly to the load or sling, ensuring it is directly above the
centre of gravity of the load.

OPERATION
1. Ensure that no obstruction prevents a clean lift
2. Gently raise or lower the load by pulling the hand chain through the block in the
desired direction - Clockwise to lift and anti-clockwise to lower.
• While lifting or lowering a load, the hand chain should be pulled steadily to
prevent it from jerking or tangling.
• Lift the load a few centimeters and check stability before commencing full lift.
• DO NOT allow anyone to walk or work under a lifting load.
• When lowering a load, be aware that when the hand chain is released, the load
will not stop immediately but may continue for a few more millimeters as the
brake takes effect.
NOTE: The brake may get hot with continued use.
3. After operation, clean the chain block and lubricate the chain if required. Store it
in a dry place to protect it from rust and corrosion.
JAMMING
Stop operation immediately if the hand chain cannot be pulled any further. Don't try
to force the chain.
Proceed inspection as follows:
a. If there is anything entangled with the load.
b. Whether there is any trouble with the parts of the block.
c. Whether the load weight is over the rated capacity of the block.
MAINTENANCE
EVERY SIX MONTHS
1. Fully unwind the lifting chain and check its general condition for corrosion, wear
and signs of stretching or fracture.
2. Lubricate the chain and moving parts to inhibit corrosion.
3. Check the security and condition of the suspension point.
4. Check the condition of hooks and the tightness of all bolts and screws.
NOTE: When in constant use, the chain block should be inspected more frequently. If
in doubt about the use or maintenance of this equipment, consult you local
authorised CLARKE dealer.
