Chain bar maintenance (Fig. 28)
Regular lubrication of the chain bar (guide rail for the chain and teeth) is essential.
The chain bar needs the maintenance described in the following section in order for
the saw to work at an optimum level of performance.
m NOTICE
The sprocket tip on your new saw has been pre-lubricated at the factory. Failure to lu-
bricate the guide bar sprocket tip as explained below will result in poor performance
and seizure, voiding the manufacturer’s warranty.
To lubricate the sprocket tip
If the saw is used intensively it will be necessary to lubricate the guide bar sprocket
tip (J) regularly (once a week).
To do this, first thoroughly clean the 2 mm hole (K) at the tip of the guide bar, and
then press in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available in specialty retail trade.
