Maintenance and care
ENGLISH 9
5.2 Air Filter Maintenance
The air filter separates and retains dirt before the
air reaches the combustion chamber. This reduces
engine wear.
Regular maintenance increases engine life.
Clogged air filters cause performance loss and
increased fuel consumption. This leads to a higher
toxin level in the exhaust gas and also makes
starting more difficult.
When the machine is used all day, the air filter
should be cleaned daily. In severe dust conditions
clean more often in between.
Undo the screw (Fig. 1, Pos 8) completely (screw
is retained inside the filter cover) and remove the
filter cover.
For a simple cleaning procedure we recommend
tapping the air filter.
Never use a high pressure air cleaner nor wet
or moist cleaning. Do not use solvent or oil
bath cleaners!
If engine rpm's tend to drop although the
carburettor adjustments are perfectly set, the air
filter cartridge is clogged and must be replaced by
a new one (Type 444: Order-Nr. 20 48 282)
(Type 451: Order-Nr. 20 48 280).
Never do realignments on the factory carburettor
settings in order to balance a clogged air filter
system. This procedure would cause engine
damages due overload of the engine.
Warranty claims cannot be accepted for damaged
engine parts caused by improper care and
maintenance
Insert the new or cleaned fabric air filter into the
casing.
Secure the filter cover by turning the screw (Fig. 1,
Pos 8) clockwise.
5.3 Spark Plug
The correct spark plug with thermal range 200 is
available under the following brands:
BOSCH WSR6F
The correct electrode gap is 0.5mm.
Caution: Check the plug after every 50
operating hours and replace if electrodes
are worn.
5.4 Storage Hints / Transport Hints
If the unit is to be laid up or kept idle for any length
of time, proceed as follows:
a) Rinse and clean thoroughly. Never use formula
container of your mist blower for storing
chemicals.
b) Shut off fuel cock and keep engine running until
lines and carburetor are empty. Otherwise
gasoline evaporates, and the remaining
lubricant would clog the carburetor ducts.
c) Remove spark plug and squirt an ounce or two
of corrosion inhibitor (LPS, WD-40 etc.) or plain
engine oil into the cylinder. Crank engine
several times to spread the agent, and then
reinsert spark plug.
d) Please store your machine away from sunlight,
order to protect of the materials against
influence of ultraviolet radiations.
e) Before putting the unit back into service,
remove and clean spark plug; crank engine a
few times with plug removed.
For transport in a vehicle, ensure the
mistblower is well secured to avoid fuel
spillage.
Completely empty the fuel tank before extended
storage or shipment.
