electrode gap is 0.024 inch (0.6 mm). The spark plug
should be replaced after about a month in operation or
earlier if necessary.
CAUTION: Always use the recommended spark
plug type. Use of the wrong spark plug can damage
the piston/cylinder.
Air lter
The air lter must be regularly cleaned to remove dust
and dirt in order to avoid:
● carburetor malfunctions
● starting problems
● loss of engine power
● unnecessary wear to engine parts
● excessive fuel consumption
Clean the lter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air lter
Remove the air lter cover and take out the lter.
Wash it clean in warm, soapy water. Rinse thoroughly.
Ensure that the lter is dry before retting it.
An air lter that has been in use for a long time cannot
be cleaned completely. The lter must therefore
be replaced with a new one at regular intervals. A
damaged air lter must always be replaced.
Bevel gear
The bevel gear is lled with the right quantity of grease
at the factory. However, before using the machine
you should check that the bevel gear is lled three-
quarters full with grease. Use special grease. The
grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
Sharpening grass cutters and grass
blades
aWARNING: Always stop the engine before
doing any work on the cutting attachment. This
continues to rotate even after the throttle has
been released. Ensure that the cutting attachment
has stopped completely and disconnect the lead
from the spark plug before you start to work on it.
● See the cutting attachment packaging for correct
sharpening instructions.
● Sharpen blades and cutters using a single-cut at
le.
● Sharpen all edges equally to maintain the balance
of the blade.
aWARNING: 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 specied type.
Maintenance schedule
The following is a list of the maintenance that must
be performed on the machine. Most of the items are

workshop.
Weekly Maintenance:
● Clean the outside of the machine.
● Make sure the throttle trigger lock and the throttle
function correctly from a safety point of view.
● Check that the stop switch works correctly.
● Check that the cutting attachment does not rotate
at idle.
● Clean the air lter. Replace if necessary.
● Check that the cutting attachment guard is
undamaged and not cracked. Replace the cutting
attachment guard if it has been exposed to impact
or is cracked.
● Check that the trimmer head is undamaged and not
cracked. Replace the trimmer head if necessary.
● Check that the locking nut of the cutting equipment
is tightened correctly.
● Check that nuts and screws are tight.
● Check that there are no fuel leaks from the engine,
tank or fuel lines.
Monthly Maintenance:
● Check the starter and starter cord.
Annual Maintenance:
● Clean the outside of the spark plug. Remove it and
check the electrode gap. Adjust the gap to 0,6 mm
(1/32 inch) or replace the spark plug. Check that
the spark plug is tted with a suppressor.
● Clean the outside of the carburetor and the space
around it.
● Check that the bevel gear is lled three-quarters full
with lubricant. Fill if necessary using special grease.
● Check the fuel lter from contamination and the
