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 filter* (1) (green) with wire
mesh for normal operating conditions
and winter operation.
HD filter* (2) (black) for dry and ver dust
work areas.

conditions and winter operation or the
fleece filter* (non woven element) (4)
for dry and ver dust work areas.
STIHL filters have a long service life
when kept in a dry condition.

dry condition.
