4.10 To examine the spark plug
NOTICE! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/
cylinder.
• If the machine is low on power, difcult to start or
runs poorly at idle speed: always check the spark
plug rst before taking other steps.
• If the spark plug is dirty, clean it and check that the
electrode gap is ok. See Technical data. Replace if
necessary.
4.11 To adjust the drive belt
If the drive feels sluggish, it may be due to a slipping
clutch and the clutch cable will then have to be adjusted.
Finely adjust the wire using the adjuster screw.
• To tension the wire and increase speed, screw the
adjustment screw counterclockwise.
4.11.1 Variable Speed
(LC 347V, LC 347VI, LC 353V,LC 353VI)
Adjust the speed of the above models by moving the
control lever rearward for slow drive and forward for fast
drive. Note that the lowest position can be engaged only
when the machine is running. If the machine is running
and the lowest position cannot be engaged, the control
must be adjusted by unscrewing the adjustment screw.
Make sure the wires are not tensioned too tight. If the
lawn mower starts to drive withtout the clutch lever is
beeing operated, extend the wire.
•To extend the wire and reduce speed, screw the
adjustment screw clockwise.
If the drive still feels slow, the belt will have to be
replaced. Contact an authorised service workshop.
4.12 Air lter
• Remove the air lter cover and take out the lter.
• An air lter that has been in use for a long time
cannot be cleaned completely. The lter must
therefore be replaced with a new one at regular
intervals. A damaged air lter must always be
replaced.
• When reassembling, make sure that the lter
completely seals against the lter holder.
