Assembly
Make sure the cutter centres correctly on the shaft. 
Fit the washer and tighten the bolt correctly. The bolt 
should be tightened with a torque of 45-60 Nm.
Pull the blade around by hand and make sure it 
rotates freely. Test run the machine.
Spark plug
If the machine is low on power, difficult to start or runs 
poorly at idle speed: always check the spark plug first 
before taking other steps.
If the spark plug is dirty, clean it and check that the 
electrode gap is 0.5 mm. Replace if necessary.
Adjusting the clutch wire 
Finely adjust the wire using the adjuster screw.
 Roughly adjust the cluch wire when the fine 
adjustment is not enough.
Extend the wire using the fine adjustment screw.
Roughly adjust the cluch wire by attaching it to the 
different brackets on the clutch bar. Then adjust the 
wire finely.
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. 
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.
NOTICE! Always use the recommended spark plug 
type! Use of the wrong spark plug can damage the 
piston/cylinder.
