securely fit slings to the body of the hoist or use the top hook if possible. Do not lift by the controls, valves, or the air set.
MOUNTING THE HOIST
The air hoist is designed as a LIFTING MACHINE and as such is designed exclusively for the lifting loads vertically. Non vertical lifting will
result in premature wear of the chain and chain guide and may result in damage to the limit arms or a failure of the limit arms to operate.

CLOSE HEADROOM WORKING
The lower hook of the TMH hoist includes a swivel arrangement. This allows the load to turn without twisting the chain. However, when
repeatedly handling loads with the bottom hook close to the hoist, especially when rotation of the load is prevented, there is tendency for the
chain to attempt to enter the guide at an angle. This is particularly pronounced on two fall units. If this problem is noticed when doing a trial lift,
a high quality ball bearing swivel should be mounted below the bottom hook of the hoist.
CHAIN COLLECTORS
If the hoist has been supplied with a chain collector bag or bucket, and the chain has been stored within it during shipment, remove all the
chain from the collector by hand, and remove any knots or twists.

1.5 TECHNICAL CHARACTERISTICS
TheWLLofthehoistwillbemarkedonthehoistnameplateandalsointhehoistspecicationsupplied.
The reactions on the powered hoist on the support, runway beam or crane should have been taken into account in the design of the structure.
The structure should be at least 25% stronger than when using manual equipment due to the shock loading applied by the operational speeds
and the starting and stopping of the hoist.
