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.
Note! Always use the recommended spark plug type! Use
of the wrong spark plug can damage the piston/cylinder.
Lubricating the bar tip sprocket
Lubricate the bar tip sprocket each time you refuel. Use
the special grease gun and a good quality bearing grease.
Needle bearing lubrication
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week). CAUTION! Use only high quality bearing grease or
engine oil. See instructions under the heading Cutting
equipment.
Adjustment of the oil pump
The oil pump is adjustable. Adjustments are made by
turning the screw using a screwdriver or combination
spanner. The machine is supplied from the factory with
the screw set to position 2. Turning the screw clockwise
will reduce the oil flow and turning the screw anti-
clockwise will increase the oil flow.
Recommended settings:
Bar 18"-20":
Position 1
Bar 22"-26”:
Position 2
Bar 28" - :
Position 3
!
WARNING! The engine must not be
running when making adjustments.
