General
WARNING Moving parts
Never perform service on a loaded hoist or a hoist that is connected to air
supply. A moving load can cause severe bodily injury.
The hoist must be unloaded and disconnected from the air line before any
►
service or adjustment is performed. Exception to this is permitted only
when load or compressed air supply is required to make the adjustment.
Take the hoist out of service for a checkup at the slightest sign of fault.
In case of jarring or rattling – the chain, chain wheel and chain guide should be
inspected with respect to wear and damages.
Maintenance instructions
Service recommendations
Preventive maintenance is recommended at regular intervals. See the detailed
information on preventive maintenance. If the product is not working properly,
take it out of service and inspect it.
If no detailed information about preventive maintenance is included, follow
these general guidelines:
• Clean appropriate parts accurately
• Replace any defective or worn parts
Regular maintenance
Load chain
Our recommendation is to check the chain before each shift regarding wear. Lu-
bricate the chain at least once a month and after every 500 lifts. Make sure to
lubricate the chain when unloaded. The chain links that run most frequently
over the chain wheel inside the hoist will be worn first. Be especially observant
of these links.
• Be specifically observant of a wear pattern according to the illustration be-
low. If this occurs on any of the chain links, the chain needs to be changed
immediately.
• Make sure that the load chain wear, at any part of the chain, does not ex-
ceed , measured inside over seven well stretched links.
• Whenever the load chain is changed, the chain wheel should also be
cleaned, inspected for wear and then lubricated.
