Safety Instructions
You should always:
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.
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
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.
3. Use the correct size and pitch
of propeller for your engine, refer
to the "Propeller Chart" on page 16 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 out
against the washer and propeller. An
anti-loosening nut (or “jarn” nut) is
suggested for all 4-cycle engines.
5. Inspect the lightness 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” 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.
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.
