9.5 Air Filter Maintenance

Contaminated air filters cause a reduction in engine
performance and increase fuel consumption with more
pollutants in the exhaust gas. Engines are less likely to
start readily with a contaminated air filter.
Carry out the following maintenance jobs regularly.
Fig. 17
Before opening the air filter, close the choke
prevent dirt entering the carburettor.
! Turn the wing screw (51) at the air filter cover (8)
anti-clockwise.
! Flip the top of the air filter cover forward and
remove.
! Remove the fabric air filter (52).
! Clean the area around the filter.
When using the equipment all day, clean the fabric air
filter daily. Under extremely dusty conditions, clean the
filter several times during the day as well.
Simply tapping the filter is the best cleaning method.
Never wash or clean the air filter with compressed
air or by wetting it; never place in an oil bath or into
cleaning solution.
The air filter is blocked, if the engine speed noticeably
drops when the carburettor is correctly adjusted. Under
these circumstances, the filter needs replacing (part no.
20 48 154).
Low engine speed due to a blocked air filter must never
be compensated by incorrect carburettor adjustments.
This would cause the engine to overload, resulting in
severe engine failure.
Engine failure caused by incorrect care is excluded
from our warranty.
!
Insert the new or cleaned fabric air filter into the
casing.
!
Position the air filter lid with the lower guiding pins
onto the housing and push into place.
! Secure the filter cover by turning the wing screw
(51) clockwise.

9.6 Information about the spark plug

Check the spark plug regularly after 50 hours of
operation.
Fig. 18
! Press the back tab of the spark plug cover (9) down
to
and remove in an upwards motion.
! Disconnect the spark plug cap.
! Unscrew the spark plug and dry the electrodes.
The spark plug should be replaced after 100 hours of
operation or if the electrodes are badly worn.
Do not turn the engine over while the spark plug has
been removed or the spark plug cap has been
disconnected from the high-tension ignition cable. A
spark may cause a fire!
Spark plugs with resistor (thermal value 200) are
available in different brands under the following
description:
BOSCH
CHAMPION
The correct electrode gap is 0.5 mm.
Only use spark plugs, where the contact nut has been
firmly fitted. Loose connectors may produce sparks,
which can cause a fire. Before restarting the engine,
check the high-tension ignition cable for any damage to
its insulation and ensure the cable is connected
securely to the plug cap
! Insert the spark plug into the cylinder head and
tighten it.
! Push the spark plug cap firmly over the spark plug.
! Position the spark plug cover onto the housing by
aligning it with the guiding pins, push down and click
into place.
