MAINTENANCE AND REPAIRS
Maintenance of chain-brake
The chain-brake is subjected to normal wear. For serving a good performance, it has to be
maintained by well trained personnel (e.g. after-sale-service) at regular intervals:
Professional fulltime work
every three months
Half-professional (Agriculture & Construction) twice a year
Hobby and free-time user
once a year
Keeping the bar proper
Turn over the bar after every sharpening of the chain or replacing the chain to avoid wear
out on one side only especially at the return steering and the underside.
Clean regularly
1 = Oil inlet hole
2 = Oil outlet port
3 = Bar groove
During the first period of operation
Always pay attention to: Opening of valve only with released chain-brake. Opening of valve at
blocked chain-brake (chain is stalled) causes in a short time to damages on the chain drive
(chain-brake).
During the operation
Check tension of chain more often!
A new chain has to be adjusted more often than one that is in use for longer!
