Remove the air filter cover and take out the filter. Wash it 
clean in warm, soapy water. Ensure that the filter is dry before 
refitting it. 

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.

The bevel gear is filled with the right amount of grease at the 
factory. However, before using the machine you should check 
that the bevel gear is filled 3/4 full with grease. Use 
JONSERED special grease.

The grease in the bevel gear does not normally need to be 
changed except if repairs are carried out.

The spark plug condition is influenced by:

•

Incorrect carburetor adjustment.

•

An incorrect fuel mixture (too much or incorrect type of 
oil).

•

A dirty air filter.

These factors cause deposits on the spark plug electrodes, 
which may result in operating problems and starting 
difficulties.

If the machine is low on power, difficult to start or runs poorly 
at idle speed: always check the spark plug first before taking 
any further action. If the spark plug is dirty, clean it and check 

that the electrode gap is 0.5 mm (0,020"). The spark plug 
should be replaced after about a month in operation or earlier 
if necessary.

CAUTION!  Always use the recommended spark plug type! 
Use of the wrong spark plug can damage the piston/cylinder. 
Check that the spark plug is fitted with a suppressor.

IMPORTANT! Use only JONSERED replacement parts. 
Use of other brands of replacement parts can cause 
damage to your unit or injury to the operator or others. Your 
warranty does not cover damage or liability caused by the 
use of accessories and/or attachments not specifically 
recommended by JONSERED.
