► 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.

► Regularly clean the oil inlet hole (1), the oil‐

way (2) and the bar groove (3)

► 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:

► 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.

23 Air Filter System

The air filter system can be adapted to suit differ‐

ent operating conditions by installing a choice of

filters. Changing the filter is quick and simple.
The saw comes standard with either a fabric filter

or a fleece filter.

► Place fingers behind the air filter (1), press

removing and installing the air filter.
► Blow out the filter with compressed air from

the clean air side.

pressed air is available:
