► 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 Minimum
groove
depth
Picco 1/4" P 4.0 mm
Rapid 1/4“ 4.0 mm
Picco 3/8" P 5.0 mm
Rapid 3/8“; 0.325“ 6.0 mm
Rapid 0.404“ 7.0 mm
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.

Control lever in the direction of STOP or † –
