MAINTENANCE
M46-190AWREX
Finely adjust the wire using the adjuster screw.
Air filter
• Remove the air filter cover and take out the filter.
• An air filter that has been in use for a long time cannot
be cleaned completely. The filter must therefore be
replaced with a new one at regular intervals. A
damaged air filter must always be replaced.
• When reassembling, make sure that the filter
completely seals against the filter holder.
Clean the paper filter
• Clean the filter by knocking the filter against a flat
surface. Never use solvent with petroleum, for
example, kerosene, or compressed air to clean the
filter.
Cleaning the foam plastic filter
• Remove the foam plastic filter. Wash the filter well in
tepid soapy water. After cleaning, rinse the filter well
in clean water. Squeeze out and allow the filter to dry.
NOTE! High pressure compressed air can damage
the foam. After cleaning the filter should be oiled using
engine oil. Wipe away excess oil by pressing a clean
cloth against the filter.

Oil change

• Empty the fuel tank.
• Unscrew the oil filler cap.
• Place a suitable vessel to collect the oil in.
• Drain the oil by tipping the engine so that the oil runs
out through the filler pipe. When the machine is tilted,
make sure the air filter always is placed in the highest
position. Ask where you can dispose of surplus
engine oil at your local petrol station.
• Fill with new engine oil of a good quality. See
instructions in the section "Technical data".

Fuel system

• Check that the fuel cap and its seal are not damaged.
• Check the fuel hose. Replace if necessary.
