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 
suit different 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.

Fabric filter

For normal operating conditions and 
winter operation.

Fleece filter

For dry and very dusty work areas.
