7. MAINTENANCE AND REPAIR
Visual inspection and testing of the hoist and lubricating the chain are the only interventions that should be
undertaken by the user of the hoist.
All other maintenance, replacement, adjustment interventions that involve the opening of the hoist housing
should only be carried out by LITEC Italia authorised service engineers.
The hoist must therefore be delivered to LITEC authorised centre that will issue special control and
maintenance reports.
Maintenance and service are preventive measures designed to preserve the full functionality of electric chain
hoists. Non-compliance with maintenance and service routines can result in reduction in the useful function
of and/or damage to chain hoists.
Maintenance work encompasses visual checks and cleaning routines. Service work includes additional
functional checks. During the functional checks, all securing elements and cable clamps must be checked for
secure seating.
During maintenance and service work, general accident prevention directions, special safety directions as
well as hazard protection instructions should be followed.
Before carrying out any kind of maintenance, repair, cleaning or any activity that requires a manual
intervention on the machine, disconnect the power supply to the hoist.
Ensure the power cannot be re-
connected to the hoist be securing or clearly marking the plug “do not
connect”.
7.1
CHAIN MAINTENANCE
Use of commercial or other manufacturers’ chain and spare parts to repair the hoist may cause load loss.
Use only chains supplied by the manufacturer.
The valid accident prevention regulations and the stipulations of
ISO 7592
must be observed during all
maintenance work.
7.1.1 Cleaning Chain
Clean the load chain with acid-free solvent and coat with new high pressure oil. Wipe excess oil to prevent
dripping. Never apply grease to the chain.
7.1.2 Lubrication of Chain
Lubricated chain has a much higher (15-20 times) lifecycle than a dry chain. We recommend to lubricate the
chain along its entire length before putting into operation. It must be ensured that all chain links are
lubricated. During lubrication, ensure that the lubricant penetrates into connection point between chain links.
This spot is most susceptible to wear. Change-over link should be lubricated especially careful. Change-over
