Starting - O.S. engine MAX-75AX-BE Instruction Manual

Be sure to use an electric starter to
start the engine.
Never fail to check the tightness of
!
screws and nuts, especially engine
mounting and moving parts (e.g.
throttle lever).
Starting procedure is as follows:
1. Fill the fuel tank with fuel. When filled,
prevent fuel flowing into the carburetor with
a commercially available fuel stopper, etc.
Release the stopper before starting the
engine.
2.
Make sure that plug element glows red, and
install the plug in the cylinder head.
3. Check that the needle-valve is closed. (Do
not overtighten.) Now open the needle-
valve counter-clockwise 4.5-5 turns to the
starting setting.

starter and press the starter switch for 5-6

Do not choke the carburetor air intake when
applying the starter. This could cause an
excessive amount of fuel to be drawn into the
cylinder which may initiate a hydraulic lock and
damage the engine.
