Cleaning the paper filter
➤ Knock the dirt off the paper by banging it lightly on a hard surface or use com-
pressed air to blow through the filter.
Do not brush the paper as this will push the dirt into the fibres of the paper filter.
➤ Change the paper filter if it is heavily soiled.

Servicing the spark plugs

A
NOTICE!
• Screw the spark plugs in carefully. A loose spark plug can get very
hot and damage the engine.
• Only use the same type of spark plugs.
• When you insert a new spark plug, screw it in by 1/2 a turn once it is
firmly on the washer. If you are using used spark plugs, turning them
1/8 or 1/4 is suffice.
➤ Prepare the maintenance work, see chapter "Preparing maintenance work" on
page 25.
➤ Remove the spark plug connector.
➤ Remove the spark plug using a spark plug wrench.
➤ Make a visual inspection of the spark plugs.
Replace the spark plug if it is clearly worn or the isolator is damaged or broken.
If the spark plug is just dirty, clean it with a steel brush.
➤ Measure the distance between the electrodes with a thickness gauge (fig. 8,
page 7). It must be 0.7 – 0.8 mm and can be corrected by bending the electrode
if necessary.
➤ Check whether the spark plug seal is intact.
➤ If so, screw in the spark plugs by hand to avoid damaging the thread.
➤ Tighten the spark plugs using a spark plug wrench so that the washer is pressed
together.
➤ Finish the maintenance work, see chapter "Finishing maintenance work" on
page 25.
