(garages, galleries, cellars, etc.). When in operation, the engine produces waste heat, resulting in heat-up 
of  various  engine  components  (exhaust,  engine  cylinder),  which  may  cause  serious  burns.  These 
components may cause fire, when in contact with flammable materials. 

DANGER                   

 

Petrol  fumes  are  extremely  flammable  and  explosive  substances  that  max  cause  burns,  fire  or  even 
explosion, when handled improperly. Let the engine cool down for 5 minutes before adding petrol into 
the tank. Then proceed with careful removal of the tank lid and start pouring the petrol in with caution. 
NEVER fill the fuel up to the rim, since petrol warms up during engine operation and swells, which may 
result in leakage through the lid and subsequent explosion of fire. NEVER tip the high-pressure device 
into such position, where petrol may leak from the tank. NEVER attempt to start the engine with damaged 
components in the fuel supply, ignition or safety features. 

 

Push the engine switch 

and the fuel switch 

D

 into the 

ON (I) 

position.

 

Shift the speed control lever 

B

 into the  

 position. 

Shift the choke control lever 

A

 into the 

CHOKE position.

 

Grasp the pump grip with one hand firmly and use the other hand to 
hold the starter cord grip.  
Pull the starter cord to the point, where you feel resistance from the 
engine. Then pull the grip sharply to prevent recoil. If the engine fails 
to start on the first attempt, repeat the starting process by pull the 
starter grip again. 

 
 
CAUTION! 

The  starter  cord  recoil  (engine  resistance 

against the direction of starter cord pull) will draw your shoulder and hand towards the engine 
faster than you are able to release is, this may result in spraining, contusion or breakage of 
your limb. 

 
Once the engine has started up, shift the choke control lever 

A

 

into the 

RUN position SLOWLY. 

 
 
 

ENGINE SHUTDOWN 

Engine shutdown comprises the following steps 

Shift the engine speed control lever (page 4) 

B

 to ½ of the turn 

towards the position 

 and let the engine run for at reduced 

speed for 15-20 seconds. Then proceed with turning the engine ignition switch 

and the fuel switch

 D 

into the 

OFF position. 
 

CAUTION 

The engine is fitted with the engine oil level sensor (not every model though) to 

switch the engine off, when the engine oil drops to hazardous point. 

This function does not 

substitute the regular inspection of engine oil level.

 Disregard to the regular inspections 

may result in irreversible damage to internal components of the engine. Such damage is not 
covered by the warranty. 

NEVER

 spray any water on the engine when hot. Such actions may cause ingress of water 

into the fuel system or the ignition system. Clean the engine with a damp cloth and compressed 
air to remove dust from the air filter compartment.
