7 Muffler
Never use a chain saw
that has a faulty muffler.
Regularly check that the
muffler is securely
attached to the chain saw.
If the muffler on your saw
is fitted with a spark
arrestor mesh this must
be cleaned regularly. A
blocked mesh will cause
the engine to overheat
and may lead to serious
damage.
Never use a muffler if
the spark arrestor mesh
is missing or defective.
NEVER USE A CHAIN SAW WITH FAULTY
SAFETY EQUIPMENT. CARRY OUT THE
CHECKS AND MAINTENANCE MEASURES
DESCRIBED IN THIS SECTION. IF YOUR
CHAIN SAW FAILS ANY OF THESE CHECKS
CONTACT YOUR SERVICE AGENT TO GET IT
REPAIRED.
CUTTING EQUIPMENT
This section describes how to choose and maintain your cutting
equipment in order to:
• Reduce the risk of kickback.
• Reduce the risk of the chain breaking or jumping.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
The 5 basic rules
1 Only use cutting
equipment
recommended by us!
See the
”Technical data”
section.
2 Keep the chain cutting
teeth properly
sharpened! Follow our
instructions and use the
recommended file
gauge. A damaged or
badly sharpened chain
increases the risk of
accidents.
3 Maintain the correct
raker clearance! Follow
our instructions and
use the recommended
raker gauge. Too large a
clearance increases the
risk of kickback.
4 Keep the chain properly
tesioned! If the chain is
slack it is more likely to
jump off and lead to
increased wear on the
bar, chain and drive
sprocket.
5 Keep cutting equipment
well lubricated and
properly maintained!
A poorly lubricated chain
is more likely to break and
lead to increased wear on
the bar, chain and drive
sprocket.
