MAINTENANCE AND INSPECTION
DAILY INSPECTION
CAUTION

For daily operation, be sure to carry out the following check prior to operation.

In case of any abnormality, stop operating the hoisting unit and take proper counter-measure by a specialist
possessing enough knowledge on the unit or by a dealer of our products.

Do not make continuous running under abnormal condition as it is very dangerous and might lead to an severe
accident.
(1) Check if the end of the load chain without hook (chain stopper pin) is fixed correctly. Check also if the chain stopper pin
is not deformed or rotates smoothly.
(2) Are firm connections made between the top hook and the hoist body, the body and the load chain, and the load chain
and the bottom hook respectively?
(3) Are visually no deformations of the top and bottom hooks noticed?
(4) Are no parts missing? Are no severely deformed portions noticed?
(5) Is the load chain well lubricated? Does it show any remarkable damages or deformations?
(6) Check whether the hand chain runs easily and smoothly on operation and smooth ratchet sound is heard during lifting.
Immediately stop operating the chain hoist and make repair of it, when such abnormalities as mentioned above (item 1
through 6) are found.
Inspection of chain stopper pin
Check if the chain stopper pin(Fig .11-1 (1) ,on the reverse page) is fitted with a genuine snap ring(Fig.11-2). Split pin and
the like other than a genuine snap ring should 3) not be used.

A split pin cannot guarantee smooth rotation of the chain stopper pin and thus the load chain would be tangled at the
chain stopper pin. Since this is very dangerous, use only a genuine snap ring of our make.

How to dismantle the snap ring.
As the Fig.11-2 shows, hold the edge of the snap ring by pincers and pull it up forward(until the ring leaves the pin head). By
pulling down, the snap ring comes off the pin.

When assembling the snap ring, insert the top of the two axes into the hole to push them in.
Note) The two axes of the snap ring should be on the reverse side (back side) and the ring on the front side. Do not turn the
other way. When the snap ring is lost, do not use any substitution but only genuine one.

Chain stopper(used only for 3t type chain hoist)
Check if the chain stopper is fitted to the sixth link from the arm of the chain hoist for 3t. Check also if any screw is not
loose.
