Congratulations on your purchase
of a Saito 4-cycle engine. When
cared for properly, these high-
quality, finely crafted engines
offer many years of modeling
enjoyment.

This instruction manual has been
developed to ensure optimum per-
formance from the Saito engine
you’ve purchased.  The instruc-
tions must be read thoroughly
prior to mounting and running the
engine.

NSTRUCTIONS

This model engine will give you
considerable pleasure, satisfaction
and performance if you strictly
follow these safety instructions
and take heed of the warnings as
to its safe and proper use.
Remember at all times, THIS
ENGINE IS NOT A TOY, 
but
rather a precision-built machine
with more than enough power to
cause harm if misused or if the
safety precautions are not
observed.

Y

OU SHOULD ALWAYS

:

1. When running the engine, be
sure that all spectators, especially
children, are at least 20 feet away.

2. Use the correct size and pitch
of propeller for your engine; refer
to the propeller chart in this man-
ual.

3. It is extremely important to bal-
ance the propeller prior to instal-
lation of the engine. Failure to do
so may cause damage to the Saito
engine and/or the airframe. Install
the propeller with the convex
(curved) side facing forward.
Securely tighten the propeller nut
against the washer and propeller.
A ”jam” nut (or anti-loosening
nut) is suggested for all 4-cycle
engines.

4. Keep your face and body away
from the path of the propeller
blades when starting or running
your engine.

5. Never allow your hands to
come close to the propeller.
Utilize either a “chicken stick” 
or electric starter to start the
engine.

6. Make all carburetor adjust-
ments from behind the propeller.

7. To stop the engine, cut off fuel
supply (pinch or disconnect the
fuel line to the carburetor), or use
the throttle linkage to shut off the
air.
