MAINTENANCE
Cleaning the air filter
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.
Bevel gear
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.
Spark plug
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.
