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:
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.
