If the motor or the whole model with this motor provide another person, tell him safety 
instructions and operating instructions. If you do these guidelines and / or instructions lost 
or destroyed, you can re-download them from our website. 

 

Please take great care in securing the motor in model and check it regularly. Likewise, 
check the propeler mounting screw. 

It is not allowed to move when the engine is running in the plane of rotation of the 
propeller and in front of it (in the case of classical, towing arrangement - CW). Attention to 
touch the spinning propeller! When you start your model and warming up the motor well 
secured against rolling away, preferably with qualified persons. 

Do not allowed to play near the running motor small children and bad moving people also 
make sure pets. 

Before every start, pay attention to the condition of the propeller. Damaged, chipped or 
unbalanced propeller can dismantle the entire model, motor pull from model,  no matter 
how well done by you and even fatally injure persons standing nearby. Do not attempt to 
repair a damaged propeller, it is very dangerous and it always prefer to immediately 
replace for the same type and parameters. Use a good quality propeller manufacturers, 
designed  for petrol motors. We recommend using propellers Fiala, which is  developed and 
produced by ourselves. 

Do not start the engine in an enclosed space, but only in open spaces. 

After stoping the motor, keep in mind that the whole motor including muffler is very hot 
and can cause burns. Therefore let the motor before checking or servicing to cool down 
completely. 

Follow the rules of fire safety, smoke, etc.,  model and motor  is full of petrol. Likewise, 
please protect your eyes and mucous membranes before the petrol. 

Please follow the general rules for your own safety and also for  bystanders and use your 
own common sense according to the principle - what could theoretically happen, will also 
one day become. 

Note .: Our advice to the conclusion - many modelers have for complex, large and 
expensive models prepared their own list of performing pre and control operations, so-
called - Check List. It can still be advantageously incorporate a list of specific control 
operations on the motor and drive unit as a whole.
