General
Keep all parts of your body away from the hot surfaces.
The ignition lead should always be removed from the
spark plug before repair, cleaning or maintenance work.
Carburettor
Adjustment of the idle speed
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
The factory idle speed setting is 2,000 rpm. Use the
adjustment screw at the upper edge of the carburettor if
the idle speed has to be adjusted.
Muffler
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
The muffler is equipped with a special spark arrestor
mesh. The spark arrestor mesh should be cleaned once
a month. This is best done with a wire brush.
To remove the spark arrestor mesh proceed as follows:
Remove the exhaust duct.
Remove the spark arrester.
Pull out the spark arrestor mesh and clean using a wire
brush. Replace the spark arrestor mesh if it is defective.
CAUTION! Never use a machine with a defective muffler.
Check regularly that the muffler is complete and secured
correctly. (1,2). Tighten the screws, 8-10Nm.
Check that the spark arrester and the exhaust duct are
screwed in place correctly (5). Tighten to 2-3 Nm.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
Cooling fins on the cylinder.
Air intake screen
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder. Check that the nozzles
are not blocked.
Air intake screen
Check that the air intake is not blocked on all sides
including the underside, for example, by leaves or
rubbish. A clogged air intake reduces the machine’s
blowing capacity and increases the engine’s working
temperature, which can result in engine failure. Stop the
engine and remove the object.

during use and remain so for some time
after stopping. This also applies at idle

skin. Remember the risk of fire!
!
WARNING! Never use the blower if the
screen is not in place. Before use, check
that the screen is in place and
undamaged.
