PERIODIC CHECKS
Perform regular inspections on the jack according to the following table. The inspections are com-
pulsory and are required to prevent failures and accidents. They must be carried out when the hoist
is first installed and at the indicated intervals; if the hoist is used frequently and/or with loads close
to the maximum permitted, it is necessary to reduce the time intervals shown below. Check that
there are no deformations, cracks, bending, crushing, wear or rust. Always record the inspections
performed and any repairs.
