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.
Functional inspection
General inspection
• Check that nuts and screws are tight.

MAINTENANCE
Throttle trigger lockout
The throttle trigger lock is designed to prevent accidental
operation of the throttle trigger. When the lock (A) is
pressed into the handle (= when you hold the handle) the
throttle trigger (B) is released.
Carburettor
The carburettor is equipped with fixed needles to ensure
the machine always receives the correct mixture of fuel
and air. When the engine lacks power or accelerates
poorly, do the following:
• Check the air filter and replace if necessary. When this
does not help, contact an authorised service
workshop.
Adjusting the idle speed
!
Start the engine and check the idling setting. When the
carburettor is set correctly the cutting blade should be still
while engine is idling.
• Adjust the idle speed using the T screw. When an
adjustment is necessary, first turn the screw clockwise
until the blade starts to rotate. Now turn the screw
anti-clockwise until the blade stops rotating.
Rec. idle speed: 2700 rpm
CAUTION! If the idle speed cannot be
adjusted so that the cutting attachment
stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
