MAINTENANCE & TROUBLE SHOOTING
TENSIONING THE DRIVE BELT
The drive belt is fully enclosed and well protected from
dust and dirt.
When the drive belt is to be tensioned, using the
combination T spanner tool to release the bolts( A) and
(B) holding the beam. Using the 5 mm ball end driver turn
the belt tensioning screw (C) so that the square headed
nut comes to the center of the marking on the cover (D).
This automatically ensures that the belt has the correct
tension. Tighten both of the bolts holding the beam using
the combination T spanner tool.
REPLACING THE DRIVE BELT
- First release the two bolts and then the belt tensioning
screw to release the belt tension.
- Now unscrew the bolts holding the beam and release
the two screws holding the beam cover.
- Remove the belt from the belt pulley.
- Remove the rear belt guard by releasing
the two screws holding the guard.
- The beam is now loose and can be removed
from the machine.
- Remove the fan shaft bearing mount by releasing
the two screws holding the bearing mount.
- Replace the drive belt.
- Assemble in the reverse order as set
out for dismantling.
- Check that the blade guard is not cracked or
damaged in any way. Replace when damaged.
- Check that the dust guard is not cracked or
damaged in any way. Replace when damaged
BELT PULLEY AND CLUTCH
Never start the engine when the belt pulley and clutch
are removed for maintenance.
CARBURETOR
The carburetor 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 authorized
service center.
ADJUSTING THE IDLE SPEED
Adjust the idle speed (A) using the small screw driver (B)
When an adjustment is necessary, first turn the screw
clockwise until the blade starts to rotate. Now turn the
screw counter-clockwise until the blade stops rotating.
Recommended idle
speed is 2700 RPM
SPARK PLUG
The spark plug condition is influenced by:
• Wrong fuel mixture (too much oil)/ poor quality fuel.
• Dirty filters.
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 other steps.

cover) (A)
