Warning
The silicone hose properly seals only if the contact surfaces are clean of dirt and grease. If
repeated connection is made, contact surfaces have to be cleaned and degreased.
Warning!
The gap between the elbows and the exhaust pipe should not exceed 2mm.
Fuel System
The gas line needs to be connected to the carburetor. Remove the protective cap from the
carburetor’s threaded nozzle and connect the gas line to it.
Warning!
Reinstalling the protective cap during extended periods while the engine is removed is
recommended to prevent the carburetor from drying up and therefore causing the engine to
malfunction..
Carburetor
There is an air intake attached to the carburetor that must not be covered!
Warning!
Do not remove or alter the air intake! It is a part of the engine responsible for its correct
operation.
Engine Oil Discharge
There is a small amount of unburnt engine oil used to lubricate the camshaft that needs to
be discharged. Please remove the cap from the small yellow threaded nozzle on the bottom
side of the engine and connect a hose to it routing the oil away, toward the chassis is
preferred.
Warning!
Keep the discharge hose clear otherwise, engine damage can occur!
Propeller Mounting
It is very important to mount the propeller correctly. There are 8 high strength steel 4mm
screws used. Please tighten them evenly. Also, make sure that the propeller is sitting flush
with the mounting plate.
Warning!
Check for tightness of the screws regularly, especially when the propeller is new and made of
wood. If the propeller comes loose, the mounting screws can break and the engine would require
authorized repair work.
In order to mount the propeller flush with the mounting plate you can measure the distance
between one blade of the propeller and an attached object, then rotate the blade 180
°
and measure
the distance between the other blade and an attached object. The distance must be the same!
