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. Any service jobs, other than 
those described in this manual, should only be carried 
out by an authorized service center. 
•  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 

Maintenance Guide Lines 
•  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. 

•  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. 

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.  

 

  

  

  

  

  

 

Petrol and Oil 
The engine of your motorized mistblower is a high 
performance 2-cycle engine and has to be operated 
with a fuel/oil mix or with a special, pre-mixed fuel for 2-
cycle engines available from specialized dealers.  
Important: For the fuel mixture, use lead-free regular 
(standard) petrol, lead-free Euro-petrol or lead-free 
Super (premium) petrol. The minimum octane rating is 
92 ROZ. 
Mixing Ratio: 
We  recommend a mixing ratio of 1 part of oil to 50 
parts fuel (1:50 - 2%) with the use of special 2-cycle oil 
SOLO 2T Oil.    
When using other 2-cycle oils we recommend a mixture 
ratio of 1:25 (4%). Note: Never store fuel mixture for 
longer than 3-4 weeks.

Running Instructions: 
For the first 5 tank fillings, also when using special 2-
cycle oils, use a mixing ration of 1:25 (4%)! 
•  Smoking or open flame is prohibited. 
•  Allow engine to cool before re-fueling. 
•  Fuel may contain solvent-like substances. Avoid 

skin and eye contact with mineral products. Wear 
gloves while refueling. Frequently change and clean 
protective clothing. Do not inhale fuel vapors. 

•  Do not spill fuel or oil. In case of spillage, 

immediately wipe off mistblower. Do not allow fuel 
mix to contact clothing. If fuel mix is spilled on 
clothing, change clothing immediately  

•  Ensure fuel or oil do not contaminate soil 

(environmental protection). Always use a suitable 
protective soil cover. 

•  Do not re-fuel in unventilated rooms. Fuel vapors 

collect at ground level (danger of explosion). 

•  Transport and store fuel and oil only in approved 

and clearly marked containers. Children should 
have no access to fuel or oil. 

•  Ensure you do not inhale exhaust fumes while using 

the machine. The use of the motorized mistblower is 
prohibited in closed rooms. 

The handling of fuel requires caution and 
consideration. It is imperative that all safety 
instructions are observed!   
•  Only refuel when the engine has been 

stopped! 

•  Clean the area around filler inlet before refueling. 
•  Remove tank lid and fill fuel mix up to the lower 

edge of the filler neck. Do not overfill. If possible, 
always use a fuel funnel with filter. 

•  Replace and secure fuel tank lid.
