WARNING Check criteria
Parts out of the following criteria should be
replaced or disposed as waste.)
Presence of marking (name plate).
Check for the grade of the load chain.
(1) Lifting and lowering function can be
smoothly carried out.
(2) Smooth ratchet sound must be heard in
lifting.
(3) The brake shows no abnormally in
lowering.
No slippage occurs.
