4.3 Spark Plug
The correct spark plug with thermal range 200 is
available under the following brands:
BOSCH WSR6F
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.
4.4 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.
4.5 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.
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.
• 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
Information about the standard settings can be
requested from the specialist workshop of our customer
service department or downloaded from our Internet
portal for specialist dealers at www.part-and-more.org.
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!
