MAINTENANCE
FIG. 53
Saw chain
WARNING!
The chain is sharp and can cause
cuts. It can cause personal injury
when handled carelessly. Always
wear protective gloves when
working with the saw chain.
!
The chain is correctly tensioned when there is no slack
on the underside of the bar, but it can still be turned
easily by hand. Hold up the bar tip and tighten the bar
nuts with the combination spanner. When fitting a new
chain, the chain tension has to be checked frequently
until the chain is run-in. Therefore check the chain
tension regularly. A correctly tensioned chain means
good cutting performance and a long lifetime.
The chain should be sharpened regularly to give
optimal performance. During normal sawing of most
species of wood this should be done at intervals of
approximately 2 hours effective cutting time (i.e. the
time that the saw chain is actually working). The chain
should be sharpened more frequently when cutting
those species of wood with a high sand content. A
special file gauge (article no. 504 98 16-78) is
available as an accessory for sharpening the saw
chain. The file gauge may be ordered from your dealer.
Adjusting the bar
When replacing the bar and chain, the position of the
bar may be altered. In order to eliminate poor cutting
results, the adjustment of the bar should be checked
(see Adjusting the bar, page 20).
