stopped at all times. If the engine had been running, 

it will be hot and the procedure should be done with 

care in order to avoid burn danger.

To check the engine oil level:

1.  Remove the oil filler cap.

AIR FILTER

WARNING

is  free  from  dirt  and  in  a  good  condition.  If  it 

is dirty, remove and clean it.To clean a foam air 

filter element wash it with home detergent and 

hot  water  and  let  it  dry.  Then  soak  it  in  clean 

saturated engine oil and gently squeeze out ex

flash-point  detergents  to  avoid  the  risk  of  a  fire  or 

explosion.

NOTE

If the engine frequently works under dusty or oth-

er severe circumstances, clean the air filter element 

every 10 hours. If necessary, change the air filter ele

and 0.8mm (Fig. 8). Replace the spark plug with 

a new one, if needed. 

4. 

Carefully thread the spark plug into the engine 

by hand.
