If groove depth is less than specified:
: Replace the guide bar.
The drive link tangs will otherwise
scrape along the bottom of the groove –
the cutters and tie straps will not ride on
the bar rails.
The air filter system can be adapted to
suit different operating conditions by
simply installing a choice of filters.
Standard wire mesh filter (1) (green) for
normal normal operating conditions and
winter operation.
HD filter (2) (black) for dry and very
dusty work areas.
STIHL filters (standard and HD) have a
long service life when kept in a dry
condition.
: Always use STIHL filters in
dry condition.
Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.
