against the lter holder. Clean the lter by brushing or
shaking it.
The lter can be cleaned more thoroughly by washing it in
water and detergent.
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.
A RedMax chain saw can be equipped with different types
of air lter according to working conditions, weather,
season, etc. Contact your dealer for advice.

Spark plug

The spark plug condition is inuenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air lter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difculties.
If the machine is low on power, difcult to start or runs
poorly at idle speed: always check the spark plug rst
before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0.026 inch

(0.65 mm). 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.
Check that the spark plug is tted with a suppressor.

Adjustment of the oil pump

The oil pump is adjustable. Adjustments are made by
turning the screw with a screwdriver. Turning the screw
clockwise will increase the oil ow, turning it anticlockwise
will reduce the oil ow.
The oil tank should become nearly empty by time fuel is
used up. Be sure to rell the oil tank every time when
refueling the saw.
