Air filter maintenance 

 
Please inspect and clean the air filter on a regular basis. If 
the filter has not been cleaned for a longer period, this will 
have influence on the engines power take-off and the 
exhaustion.   
 

1.  Clean around the air filter before it is removed.  
2.  Carefully remove the paper filter and check it. Brush 

it with a soft brush. If it is very dirty, it must be 
changed. Take care that no dirt gets into the intake 
of the engine. 

3.  Wash the black foam element on the right side in 

warm soapy water. 

4.  Press the water out of the foam element and let it 

dry. Put a few drops of SAE-30 oil on the filter to 
moisten it lightly with oil. Carefully squeeze out any 
surplus oil. Remount the element. 

5.  Check that all parts are fitted correctly and the cover 

closed as shown in the picture.  

Spark plug maintenance 

• 

Remove the spark plug cap. 

• 

Brush away any dirt and deposit of the spark plug. 

• 

Loosen the spark plug using a spark plug socket. 

• 

Check the insulation is intact.  

• 

Clean the spark plug using a wire brush. 

• 

Measure the electrode gap 0.7–0.8 mm. Avoid 
damaging the electrode.  If it is damaged, replace it 
with a new one. 

• 

Refit the spark plug. 

• 

Refit the spark plug cap. 

Storage 

• 

If the machine is likely to be stored unused for 
prolonged periods, follow the instructions below. 
This will ensure longer machine lifetime. 

• 

Use a garden hose to wash off soil and dirt. 
Remove any grass, etc. from the rotor shaft. The 
chassis number should only be cleaned with a 
damp cloth to avoid unnecessary wear. Avoid using 
a high-pressure washer during cleaning. 

• 

Wipe the tiller with a damp cloth so that all surfaces 
are clean. Wipe the surfaces down with an oily cloth 
to prevent rust.  

• 

Always store the machine in a dry, clean location.

vibration and noise levels. 

3.  To reduce noise levels further, only use the machine 

in an open environment.  

4.  Vibrations can be reduced further by holding the 

handle firmly. 

5.  To avoid disturbing others, the machine should only 

be used during the daytime.
