NOTICE
Always slacken off the chain again after finishing
work. The chain contracts as it cools down. If it is
not slackened off, it can damage the crankshaft
and bearings.
19.3.1 Short-term storage
Wait for engine to cool down. Keep the machine
with a full tank of fuel in a dry place, well away
from sources of ignition, until you need it again.
19.3.2 Long-term storage

► 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

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.
