N Turn the guide 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.
If there is a noticeable loss of engine
power
N Turn the twist lock 90°
counterclockwise.
N Remove the shroud upwards.
N Remove the air filter upwards.
N Wash the filter in STIHL special
cleaner (special accessory) or a
clean, non-flammable solution (e.g.
warm soapy water) and then dry.
NOTICE
Do not clean a fleece filter (option) with
a brush.
Always replace a damaged filter.
