Version 1.4 Operating instructions Czech Republic Please check updates of operating instructions at www.rotomotor.cz, that your engine has still the best care. (can happen important changes that will lead to longer life, higher performance or important recommendations)
To the engine worked properly and its properties have been optimized, the engine must be at operating temperature. Never adjust a cold engine. The carburetors are factory-set (in ROTOmotor). We do not recommend any dismounting of the intake manifolds, carburetors or connecting rods of the carburetors. The carburetors are on some types of ROTO engines mechanically connected and adjusted.
Exhaust The elbows of the exhaust can rotate. As soon as the desired position is achieved, the center 19 mm bolt can be tightened to fix them in place. Warning! Do not damage the exhaust elbows ends! The extension pieces that can be attached to them might not seal properly.
Use petrol 95 - 98 okt. + Motul 800 oil at 1:40. When using another brand or oil tip, warranty conditions are lost! You can order this oil at the e-shop on our website www.rotomotor.cz. Valve Adjustment In order to achieve long lasting engine performance, the valve clearance needs to be checked and adjusted if necessary after 2-3 hours of operation.

1. Send the engine to an authorized repair shop for the valve adjustment. 2. Get the information from the manufacturer at techinfo@rotomotor.cz Now the engine has been set up and no further adjustment will be needed unless other engine work is being done.
Starting for the First Time The first start has to follow these steps: !!!!!!!!!!!!!!!Make sure the ignition is turned off!!!!!!!!!!!!!!!!!!!!!!!!!!!! Engage the carburetor choke while, if possible, covering the carburetor air intake with your finger to achieve the best engine suction. Spin the propeller blade approximately ten times then uncover the carburetor air intake, turn the choke off, turn the ignition on and start the engine without the choke.
Safety Instructions Always use caution when handling the engine!!! Even slow spinning of the propeller can start the engine and cause an injury!!! Make sure to have the model airplane secured in place when starting the engine so it does not take off and cause an injury!!! Do not approach people with the model airplane while its engine is running!!! Do not touch the engine after flight, you can burn yourself!!!
