Maintenance and care
ENGLISH 8
5. Maintenance and care
Any cleaning, maintenance or repair jobs should
only be performed when the engine is stopped and
with removed spark plug cap.
The exception, of course, is carburetor tuning.
Any service jobs, other than those described in
this manual, should only be carried out by an
authorized service center. Only original parts may
be used for any maintenance and service work.
Never modify your motorized mistblower – your
personal safety is at risk.
Never service or store the machine near an open
flame.
Regularly check the fuel tank lid for sealing and
tank ventilation. Only use recommended spark
plugs. Check ignition cable for any damage.
After a running in period of approx. 5 hours, all
accessible screws and nuts (except for carburetor
mixture adjustment needles) have to be checked
and re-tightened if required.
Never operate a motorized mistblower with a
damaged muffler or without muffler (fire risk and
risk of damage to hearing). Do not touch hot
muffler.
5.1 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 (Fig. 1 - 5):
x Idling end-stop screw "T"
x Low speed mixture screw "L"
x 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.
x If the idling speed is too high, turn the idling
end-stop screw "T" anti-clockwise.
x 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.
Use the D-CUT carburettor key to adjust the idle
mixture screw "L" and the full load mixture screw
"H".
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!
