Carburetor

Always wear approved protective gloves.
Your RedMax product has been designed and
manufactured to specifications that reduce harmful
emissions.

Basic setting

• The basic carburetor settings are adjusted during
testing at the factory. The basic setting is richer than
the optimal setting and should be maintained for the
first few hours the machine is in use. The carburettor
should then be finely adjusted. Fine adjustment
should be carried out by a skilled technician.
CAUTION! If the cutting attachment rotates when the
engine is idling the idle adjustment screw T should be
turned anti-clockwise until the cutting attachment stops.

Adjustment of the idle speed

Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
Adjust the idle speed using the idle adjustment screw T, if
it is necessary to readjust. First turn the idle adjustment
screw T clockwise until the cutting attachment starts to
rotate. Then turn the screw counter clockwise until the
cutting attachment stops. The idle speed is correctly
adjusted when the engine will run smoothly in every
position. The idle speed should also be well below the
speed at which the cutting attachment starts to rotate.
T
Recommended idle speed: See the Technical data
section.
WARNING! 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.

MAINTENANCE

Muffler
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether
your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
Some mufflers are equipped with a special spark arrestor
screen. If your machine has this type of muffler, you
should clean the screen at least once a week. This is best
done with a wire brush. On mufflers without a catalytic
converter the screen should be cleaned weekly, or
replaced if necessary. On mufflers fitted with a catalytic
converter the screen should be checked, and if necessary
cleaned, monthly. If the screen is damaged it should be
replaced. If the screen is frequently blocked, this can be
a sign that the performance of the catalytic converter is
impaired. Contact your dealer to inspect the muffler. A
blocked screen will cause the machine to overheat and
result in damage to the cylinder and piston.
CAUTION! Never use a machine with a defective muffler.
!
WARNING! Mufflers fitted with catalytic
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!
