Basic information on maintenance

General information on maintenance/repair
The specified inspection and maintenance intervals (⇒ "Inspection and maintenance schedule", Page 74) apply
to normal operating conditions for the chain hoist. In the course of the annual inspection, all wearing parts are
checked.
If routine maintenance reveals that the intervals are too long, they should be adapted to the specific operating
conditions.
Electrical components
In the circuits, only fuse links with specified amperage and tripping characteristics may be used. Defective fuse links
must not be bridged.
When working on machines or machine equipment the following must be observed:
1. Wear personal protection equipment.
2. Before starting maintenance work, switch off the mains connection switch and protect it against unauthorized
or accidental reconnection to the supply by locking it with a padlock.
3. Ensure that the chain hoist is switched off, checked that it is de-energized and, in special cases, isolated,
4. Only carry out maintenance work on the chain hoist when the load has been removed.
5. Ensure appropriate clearance for working. Ensure order and cleanliness at the workplace. Components and
tools being loose or lying around may cause accidents.
6. Stop all moving parts and ensure that they cannot start moving while maintenance work is being performed.
7. Observe the relevant accident prevention regulations and statutory regulations for operation and maintenance.
8. Observe the relevant safety regulations when repairing electrical equipment.
9. After having finished maintenance work refit safety devices as prescribed and check for functioning.
Maintenance work which is not possible from the floor may only be carried out from work stands or platforms. If there
is a risk of objects falling down, the danger zone below the chain hoist must be made safe.
Instructions for repair work in the course of operation
If maintenance work on the chain hoist must be carried out in the course of operation, special safety precautions are
necessary, depending on the operating situation. In each individual case, the owner or the person assigned by him
must check whether the maintenance work may be carried out in the course of operation without risk of personal
injury and, taking into account the local conditions, implement all necessary safety precautions.
Replace damaged or deformed spring clip fasteners and split sleeves.
