Introduction
Congratulations on purchasing 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
performance from the Saito engine you
have purchased. The instructions must
be read through completely and
understood thoroughly prior to
mounting and running the engine.
Safety Instructions
This model engine will give you
considerable pleasure, satisfaction,
and performance if you strictly follow
these safety instructions and heed the
warnings for its safe and proper use.
Remember at all times it is not a toy,
but a precision-built machine with
more than enough power to cause harm
if misused or if the safety precautions
are not observed.
You should always:
1
. Mount the engine securely in a
“bench mount” or high-quality motor
mount. Never clamp the engine in
a vice.
2.
When running the engine, be sure
all spectators, especially children, are
at least 20 feet away.
3.
Use the correct size and pitch
of propeller for your engine; refer
to the "Propeller Chart" on page 14
of this manual.
4.
It is extremely important to balance
the propeller prior to installation 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. An
anti-loosening nut (or “jam” nut) is
suggested for all 4-cycle engines.
5.
Inspect the tightness of the propeller
nut prior to each flight.
6.
Keep your face and body away from
the path of the propeller blades when
starting or running your engine.
7.
Never allow your hands to come
close to the propeller. Utilize either
a “start stick (HAN113)” or electric
starter to start the engine.
8.
Discard any propeller that is nicked,
scratched, cracked or damaged in any
way.
9.
Make all carburetor adjustments
from behind the propeller.
10.
To stop the engine, cut off the
fuel supply (pinch or disconnect the
fuel line to the carburetor) or use the
throttle linkage to shut off the air.
