3.3 Spark Plug

The correct spark plug with thermal range 200 is
available under the following brands:
BOSCH
CHAMPION RCJ-6Y or similar
The correct electrode gap is 0.5 mm.
Check the plug after every 50 operating hours
and replace if electrodes are worn.

3.4 Preparation for Storage

Store the motorized mistblower in a dry room.
Cover the unit and keep inaccessible to children.
Treatment with special anti-corrosion oil is not
required if the mistblower is normally used with
SOLO 2T Oil two-cycle oil in the fuel mixture.
For extended storage, completely empty the fuel
tank.

3.5 Carburettor adjustment

The carburettor has been adjusted optimally at the
factory. Subject to the operational altitude
(mountains or low lying areas), the carburettor may
require readjustment..
Fig. 2
The carburettor has 3 adjusting screws:
Idling end-stop screw "T"
Low speed mixture screw "L"
High speed mixture screw "H"
Only qualified mechanics must adjust the
regulating screws for idle mixture "L" and
full load mixture "H".
Turn the idling end-stop screw "T" to adjust the
idling speed in accordance with the details provided
in the specification. Use an engine rev counter for
this job.
If the idling speed is too high, turn the idling
end-stop screw "T" anti-clockwise.
WSR6F
If the idling speed is too low (engine stops) turn
the idling end-stop screw "T" clockwise until the
engine runs smoothly.
If the idling speed cannot be set correctly with the
idling end-stop screw "T", request an authorised
service centre to tune the carburettor.
The following instructions are for authorised
service shops
D-CUT carburettors:
Use the D-CUT carburettor key to adjust the idle
mixture screw "L" and the full load mixture screw
"H".
Carburettors with limiter caps:
The regulating screws for idle mixture and full load
mixture can only be adjusted in a limited range.
Clean the air filter before adjusting the low speed
screw!
Let the engine run warm before adjusting the
engine speed.
The carburettor is tuned for optimum engine
performance. Use a rev counter to tune the
carburettor correctly!
Do not adjust the engine to a higher speed.
Excessive engine speed can lead to major engine
damage!
