MAINTENANCE
• Sharpen all edges equally to maintain the balance of the
blade.
Filing the saw blade
• See the cutting attachment packaging for correct
sharpening instructions.
• A correctly filed blade is essential for working efficiently
and to avoid unnecessary wear to the blade and clearing
saw.
• Make sure that the blade is well supported when you file
it. Use a 5.5 mm round file with a file holder.
• The filing angle is 15°. File alternate teeth to the right and
those in between to the left. If the blade has been heavily
pitted by stones it may be necessary to dress the top
edges of the teeth with a flat file, in exceptional cases. If
so, this should be done before filing with a round file. The
top edges must be filed down by the same amount for all
the teeth.
• Adjust the blade setting. This should be 1 mm.
Maintenance schedule
Below you will find some general maintenance instructions. If
you need further information please contact your service
workshop.
Daily maintenance
• Check throttle trigger and throttle trigger lockout function.
• Check that the stop switch works correctly.
• Check that the cutting attachment always stops when the
engine is idling.
• Clean the outside of the machine.
• Check that the harness is not damaged.
• Check that the blade guard is not damaged or cracked.
Replace the blade guard if it is exposed to impact or is
cracked.
• Check that the blade is properly centered, sharp and
without cracks.
• Check that the trimmer head is undamaged and not
cracked. Replace the trimmer head if necessary.
• A non-balanced blade/trimmer head induces heavy
vibrations that may damage the machine.
• Check that the blade nut is sufficiently tightened.
• Check that the transport guard for the blade is intact and
that it can be secured correctly.
• Check that nuts and screws are tight.
• Check that there are no fuel leaks from the engine, tank or
fuel lines.
Weekly maintenance
• Check the starter and starter cord.
• Clean the outside of the carburettor.
• Clean the outside of the spark plug. Remove it and check
the electrode gap. Adjust the gap to 0.5 mm (.20”), or
replace the spark plug. Check that the spark plug is fitted
with a suppressor.
• Clean the cooling fins on the cylinder and check that the
air intake near the starter is not blocked.
• Check that the bevel gear is filled with grease up to 3/4.
Use special grease.
• Clean the air filter.
• Clean or replace the spark arrestor mesh on the muffler
(only applies to mufflers without a catalytic converter).
Monthly maintenance
• Clean the fuel tank.
• Clean the outside of the carburettor and the space around
it.
• Check fuel hose for cracks or other damage. Change if
necessary.
• Change the fuel filter in fuel tank.
• Check electrical wires and connections.

WARNING! Always discard a blade that is
bent, twisted, cracked, broken or damaged
in any other way. Never attempt to straighten
a twisted blade so that it can be reused. Only
use original blades of the specified type.

WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of kickback.
