Basic maintenance requirements

General information on maintenance/repairs
The specified inspection and maintenance intervals ( "Maintenance schedule", Page 68) apply to normal chain
hoist operating conditions. All wearing parts must be checked in the course of the annual inspection.
If routine maintenance reveals that the intervals are too long, they should be adapted to the specific operating
conditions.
Electric components
Only fuse links with the specified amperage and tripping characteristics may be used in the electric circuits. De‐
fective fuse links must not be bridged.
Pay attention to the following when working on machinery or machine equipment:
1. Wear personal protection equipment.
2. Before starting any maintenance work, switch off the mains connection switch and protect it against unau‐
thorised or accidental reconnection to the power supply by locking it with a padlock.
3. Ensure that the chain hoist is switched off, checked that it is de-energised and, in special cases, isolated.
4. Only carry out maintenance work on the chain hoist when the load has been removed.
5. Ensure that there is sufficient freedom of movement. Keep the working area clean and tidy. Loose parts or
tools left lying around may cause accidents.
6. Stop all moving parts and ensure that they cannot start moving while maintenance work is being carried out.
7. Observe the relevant accident prevention regulations, instructions concerning appropriate use and statutory
regulations for operation and maintenance.
8. Observe the relevant safety regulations when repairing electric equipment.
9. Reinstall safety devices as required by relevant regulations and check them for correct operation after finish‐
ing maintenance work.
Maintenance work which is not possible from the ground may only be carried out from work stands or platforms.
The danger zone below the chain hoist must be fenced off if there is a risk of falling objects.
Instructions for maintenance work in the course of operation
If maintenance work has to be carried out on the chain hoist in the course of operation, special safety precautions
must be taken 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 per‐
sonal injury and, taking into account the local conditions, must implement all necessary safety precautions.
Replace damaged or deformed spring clip fasteners and split sleeves.
Defective bolted connections must be replaced.
Ensure that operating and auxiliary materials and replaced parts are disposed of in an environmentally friendly
manner.
