Maintenance and repair
Maintenance and care of the load chains
In normal use the load chains should be re-lubricated every 250 operating hours; in the event of heavy soiling,
moisture and very high prolonged loading, re-lubrication should be effected after 100 operating hours. If subject to
corrosive media the chain should be cleaned and lubricated immediately.
Chain lubrication, chain conservation
Flyer chains are correctly lubricated and are in a perfect state if:
The chain is free of exterior soiling.
When touching the chain, your finger is wetted with oil. This assures that the lubrication of the chain links is sufficient.
Type of lubricant
A low-viscosity mineral – machine – or engine oil or synthetic oil should be used. The viscosity of the lubricating oil is
to selected so that it remains low viscose at all ambient temperatures encountered.
Under normal temperature conditions, lubricating oils with a viscosity of SAE 20 to SAE 40 would be appropriate.
Lubricating methods
The lubricant can be applied by means of brush, paint brush or also using compressed air spray devices. When using
spray cans, please make sure the following basic requirement is fulfilled:
- After the thinner has vaporized, a viscosity conforming to the above-mentioned recommendation (type of
lubricant) must be met.
Cleaning the chain
If operation leads the chain to suffer so heavily from soiling that the penetration of the lubricating oil cannot be
guaranteed, the chain must be cleaned.
This is only to be effected with paraffin derivatives such as diesel fuel, petroleum, cleaner’s naphtha etc.
Do not clean with steam injectors, cold cleaners or even corrosive and acidic substances. They can directly lead to
chain damage.
If the chains have to be cleaned with steam injectors, please contact our customer service.
