► 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
Chain type Chain pitch
Picco 1/4" P
Rapid 1/4"
Picco 3/8" P
Rapid 3/8"; 0.325"
Rapid 0.404"
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 differ‐
ent operating conditions by installing a choice of
filters. Changing the filter is quick and simple.

or a fleece filter.
