SYSTEM CONFIRMATION

Once the leak is identified and repaired, reassemble all parts of the lifter.

A vacuum test, as described in the instruction manual, should be performed following any repair or
service to a vacuum lifter. All parts must be verified in relation to their function and the lifter must
pass the vacuum test before returning to operation.
