N Turn the bar over – every time you

sharpen the chain and every time

you replace the chain – this helps

avoid one-sided wear, especially at

the nose and underside of the bar.

N Regularly clean the oil inlet hole (1),

the oilway (2) and the bar

groove (3).

N Measure the groove depth – with

the scale on the filing gauge (special

accessory) – in the area used most

for cutting.

If groove depth is less than specified:

N 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

different operating conditions by the

insertion of different air filters.

Retrofitting is simple.

N Standard filter (1) with wire mesh

(green filter housing) for normal

operating conditions and use in

winter.

N HD filter (2) (black filter housing)

with felt prefilter for dry, very dusty

operating environments

When dry, STIHL filters (standard and

HD filters) attain a long service life.

N Always use STIHL filters dry

Fouled air filters will impair engine

performance, increase fuel consumption

and make the machine more difficult to

start.
