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.
