Cooling air intake
•
Clean the cooling air intake when needed.
NOTICE! A dirty or blocked air intake results in the
machine overheating which causes damage to the
piston and cylinder.
Spark plug
•
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking other steps.
•
Ensure that the spark plug cap and ignition lead are
undamaged to avoid the risk of electric shock.
•
If the spark plug is dirty, clean it and at the same time
check that the electrode gap is 0.5 mm. Replace if
necessary.
NOTICE! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the
piston/cylinder.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
•
An incorrect fuel mixture (too much or incorrect type of
oil).
•
A dirty air filter.

Tensioning the drive belt

•
For correct tensioning of the drive belt, the square nut
should be positioned opposite the marking on the belt
cover.
The tension of a new drive belt must be readjusted
after one or two tanks of fuel have been used.
The drive belt is enclosed and well protected from
dust and dirt.
When the drive belt is to be tensioned, release the
bolts holding the cutting arm.
Screw the adjuster screw so that the square headed
nut comes opposite the marking on the cover. This
automatically ensures that the belt has the correct
tension.
Tighten both of the screws holding the cutting head
using a combination spanner.
