Chain maintenance

For long chain life, good maintenance is very important. Chains without 
O-rings should be cleaned in fireproof solvent regularly and afterwards
treated with hot grease or chain spray (Shell Advance Bio Chain).
O-ring chains on the other hand are very simple to clean. The best way is to
use lots of water, but never use brushes or cleaning liquids. After letting the
chain dry, you can use a special O-ring chain spray (Shell Advance 
Bio Chain).

Also check sprockets and chain guides for wear, and replace if necessary.

Chain wear

In order to check the chain wear, regard the following indications:
Shift the gear into idling and pull the upper chain strand with approx. 
10-15 kilogram (33 lb) upwards (see figure). Now one can measure a space
of 18 chain reels at the lower chain strand. The chain should be replaced at
the latest when a space of 272 mm (10.70 in) is measured. Chains do not
always wear off evenly, therefore repeat the measurement at different pla-
ces on the chain.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New
chains wear faster if used on old used sprockets.
