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  lnstruct

ions 

  

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. 

You 

should 

always: 

1.  Mount the engine securely in a 

“bench mount” or 

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 

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 nut 

against the washer and propeller. An 

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 “chicken 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.
