Taking Care of the Guide Bar

2
1
Turn the guide bar over – every time
N
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.
Regularly clean the oil inlet hole (1),
N
the oilway (2) and the bar groove
(3).
Measure the groove depth – with the
N
scale on the filing gauge (special
accessory) – in the area used most
for cutting.

If groove depth is less than specified:

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.

Air Filter System

0.24" (6.0 mm)

The air filter system can be adapted to
suit different operating conditions by
installing different filters. Changing a
filter is accomplished quickly and simply.
The saw comes standard with either a
fabric filter or a fleece filter.
Fleece filter
For normal operating conditions and dry
work areas.
Fabric filter
For extremely cold operating conditions
(e.g. in powder or drifting snow or frost).
