SAFETY

INSTRUCTIONS

1

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 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

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

anti-looaening 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.

SAFETY

INSTRUCTIONS

Do

not

use hands,

fingers,

or

any

other

part

of

the

body

to stop the propeller:

Do

not throw

any

object into

a

propeller to stop it.

It

is

highly

recommended

that:

Safety glasses or goggles be
used when starting and running
your engine.

You do not run the engine in the

vicinity of loose gravel or sand.

The propeller may throw such
materials into your face and eyes.
The engine may also ingest these
harmful materials.

Loose clothing should be avoided
when operating your model engine.
Loose clothing may become
entangled in the propeller, creating
the possibility

of

bodily harm. Also,
all loose objects (screwdrivers,
pencils,

nickle

cadmium starters, etc.)

should be removed from your

pockets

so

that they do not fall

into the propeller.

away from the propeller.

well away from sparks, heat, or
anything that can ignite the fuel.

Glow plug clips and cords are kept

Your glow fuel is kept in a safe place

Be

ware:

Model engines get very hot while
running.

Do

not attempt to handle

them until they have cooled.

Always run your model engines in a

well-ventilated area. Similar

to

automotive engines, model engines
produce possible harmful carbon
monoxide fumes.

Remember that model engines
produce a substantial amount of
power, more than enough to seriously
injure people and/or

do

considerable
damage to property. Always use
common sense, skill and constant
observation of safety precautions.

Disassembly

Do

not

needlessly disassemble your
Saito engine. Only qualified
individuals should perform engine
repairs. Damage due to improper
disassembly will not be covered under

warranty. If it becomes necessary to
repair the engine, such as after a crash,
you can send your engine to the
authorized service center at:

Engine Parts

ldent

if

ication

It is important to be able to identify the
parts of your Saito engines. Attached
you will find an exploded view of a
Saito 4

-

stroke engine, as well as charts
that include part numbers and
descriptions. This will assist you in
easily and rapidly identifying the

respective parts of your Saito engine.

Support

Equipment

The following item, which

are

not included

with your Saito engine,

are

necessary

in

order to

operate

the model engine:

1.

Fuel.

For maximum protection and
longevity of Saito engines, Saito
recommends a fuel containing 20% oil
and 10

-

15%

nitro

methane. If

this

blend is
not readily available, the next best
selection is a high quality 2

-

cycle glow

fuel, such

as

Hangar 9 Aero-Blend,

Omega, Cool Power,

K&B, Power

Master, etc. Use

of

fuels composed

entirely of castor oil is

not

recommended.

A mix of synthetic

-

castor oil is acceptable
and can be found in the various fuels
described above.

2.

Propeller.

Refer to the "Propeller

Selection" chart, located on page 16, to

determine the best initial propeller for
your particular application. Propellers
should be balanced prior to use.

3.

Glow Plug Battery.

Your glow

plug may be properly heated by

several different sources. The Hangar

9

Power Panel (HAN106), when
accompanied by a 12-volt Sealed Lead
Acid Battery

(HAN102) and a Glow

Plug Locking Socket

(HAN120) is an

ideal source of heat for your glow

plug. A conventional 1.5

-

volt heavy

-
duty dry cell battery with a Glow Plug
Locking Socket (HAN120) or alligator
clips may also be used. Additionally,
there are several very good

glow-

starters (nickel cadmium-powered
glow plug igniters) that work well.

4.

Glow Plug Wrench.

Used to
remove and tighten glow plugs. The
Hangar

9

Long Reach Plug Wrench

(HAN2510) is an excellent wrench to

utilize, as a longer shaft may be necessaq
to access the glow plug.

This

depends

mostly upon engine installation.

5.

Manual

or

Electric Starter.

For
manual starts, a "chicken stick" is
highly recommended.

Never

use

your fingers to start any model engine.

To

do

so

invites injury. There are a

variety of electric starters on the

market. The Hangar

9

12V heavy-duty

Super Starter

(HAN110)

will work

perfectly on all Saito engines.

6.

Tachometer.

The use of a
tachometer for setting the high-speed
needle valve prior

to

flight is
encouraged. It will also be helpful
when setting the idle adjustment of the

carburetor(s).

STARTING THE ENGINE

Break

-

In

The first run

on

any engine, whether

2

-

cycle

or

4-cycle, is critical

to

the
future of the engine itself. During this
time, metal mating parts (piston and

cylinder, ball bearings, etc.) wear in.
Care must be taken that the engine is
clean and free of any dust

or

grit that
may have accumulated while building
the model.

There are two accepted methods for

breaking

in

a new engine: test stand
mounted and run or aircraft mounted
and run. Either method

is

acceptable;

however, mounting the engine

to

a test

stand allows the engine

to

be observed

throughout its operation, as well

as

elevating

it

above the ground and away

from harmful dust and dirt.

Note:

Because your engine may have

been sitting for

an

extended period of

time prior to running

it,

a few drops

of

light

oil

applied through the crankcase
breather nipple (19 on the exploded
view) and down the push-rod tubes
(40) will ensure proper lubrication

for

the first

run.

Regardless

of

the mounting method

chosen for break-in,

the

following

procedures are applicable:

1.

Use of a fuel as described in

the

“Support Equipment” section

on

page 3 of

this manual for “break-in”

purposes

is

perfectly acceptable.

2.

Use the proper glow plugs. Your

engine includes the Saito

SS

SAIP

400S

or

(HAN3011)

super glow plugs,
which are standard replacement glow
plugs for these engines.

3.

To select the correct propeller, refer

to

the “Propeller Selection” chart on

page

16

of

this manual. Remember to

balance the propeller prior

to

use

4a.

For all

.30

to

.91

engines, ensure

that the high speed needle valve

(85)

is

opened (turned counter

-

clockwise) two

and

112

turns out. This guarantees a

very rich setting.

4b.

For

all

1

.OO

to

1

.80

engines, ensure

that the high speed needle valve

(85)

is

opened (turned counter-clockwise)

5

turns out. This guarantees a very rich

setting.

Do

not

adiust the

low-speed

needle

valve (89)at this time.

The

low-speed

needle valve

is

preadjusted

at the
factory for initial break-in. Specific
instructions for adjusting the idle

of

engines (FA-30S(H)) using an

“air-bleed’ type carburetor will be
described in the section “Carburetor
Adjustments

for Air

Bleed

Carburetors”

on

page

7.

5.

The use of a tachometer is highly

recommended since the adjustment

of

a 4-cycle engine, while similar

to

that

of a 2-cycle engine, is more difficult to

“set by ear,” making

it

much easier to

damage the engine by “over-leaning.”

STARTING THE ENGINE

5

Starting

The

Engine

1.

Make sure the glow

plug(s)

is/are

installed and tightened.

2.

Be sure the propeller is properly

secured. The use of an anti

-

loosening

nut, or “jam nut,” is encouraged

on

4-cycle engines.

3.

Make sure that the fuel tank line(s)
are properly connected. The fuel
pickup line should be connected to the
carburetor spray bar

(84), and the vent

line should be connected

to

the

pressure nipple

on

the muffler. The
proper “plumbing” of the lines is
extremely important to the
performance

of

any engine. Saito
recommends the center of the tank
be mounted approximately

5

mm

lower than the carburetor center.

4.

Be certain that the muffler

is

installed properly by oiling the threads
prior

to

inserting the muffler into the
cylinder head and that the pressure line
is properly connected.

5.

Fill the fuel tank

6.

Prime the engine:

Check to make sure the glow plug is

not

connected

to

the heat source

(glow plug

clip/locking

socket)

Open the throttle fully

Rotate the propeller in a counter

-
clockwise direction 5 to 6 times
while plugging the end

of

the muffler
with your finger to draw fuel into
the carburetor.

Note:

Saito single cylinder engines
are now manufactured without the
choke valve

(92).

Due

to

the excellent

fuel draw characteristics

of

the Saito
engines, the use of the choke was
determined not

to

be necessary.

7.

Start the engine:

Turn through the prop 2 to 3 times
slowly to ensure that the engine is

not hydro-locked (see note below).

Note:

When using an electric starter,
care should be taken to be sure the
engine does not become

“hydro-

locked” (flooded with fuel). While the
electric starter will turn the engine
over, it may damage the connecting
rod or other components. If the engine
becomes hydro

-

locked, simply remove

the

glow plug and turn the engine over

a few times with the “chicken stick” or

electric starter. The excess fuel will be
forced to exit the engine via the
cylinder head.

electric starter, spin the propeller until
the engine

is

running.

Note:

A

very common error is to
remove the glow plug igniter too early.
It is suggested that the igniter be left
attached until after the engine has been
run up and the high

-

speed needle valve

has been properly adjusted.

8.

Initial break-in:

Do

not

exceed

4,000

rpm for the first

10

minutes of operation; This allows

all

parts to mate properly with good

lubrication.

Note:

Due to the excessively "rich

"
mixture setting, it may be necessary to
leave the heat source attached

to

the

glow plug.

Subsequent runs may be made while
slightly leaning out the mixture with

each tank full of fuel. Forty minutes is

considered sufficient time for normal
break

-

in prior to the first flight.

9.

After break-in:

If a test stand was used for the break-in
procedure, the engine may now be
mounted in the aircraft using a

high-

quality motor mount such

as

those
available from Saito specifically or for
Saito engines.

The idle needle valve

(89)

(or air bleed

needle valve) for the Saito

.30S(H)/

GK

engines) may now be refined.

Please refer to the

"

Carburetor

Adjustments" section on page 6 for

information on how to do

so.

The valves may

also

be checked at this

time. Refer to the

"

Engine
Maintenance" section on page 8 for
information on the valve/tappet
adjustments.

The use of

a

tachometer is encouraged

for setting the high

-

speed needle valve

(85)

prior to flight. The peak rpm
should be obtained and then reduced
by approximately

200 - 300

rpm by
turning the high-speed needle valve
counter

-

clockwise (richen). Each

engine'a peak rpm can be found on the

"

Propeller Chart" on page

16.

Over-

revving of a 4-stroke engine can cause

internal damage to the engine.

Carburetor
Adjustments

for

Two

Needle Carburetors

The low-speed, or idle needle valve

(89),

is preadjusted at the factory for

best performance during break

-

in.
After break-in it may be necessary to
"

fine tune" the low speed adjustment

using the following procedure:

1.

Start the engine and let it

warm

up

prior to attempting any adjustments.

CARBURETORADJUSTMENTS

2.

Close the throttle slowly and adjust

the low speed setting by rotating the

idle needle valve

(89)

clockwise

to

lean the mixture and counterclockwise

to richen the mixture.

Note:

The fuel mixture

is

too rich if
when openning the throttle rapidly the
engine emits white smoke and
“stutters” or “stumbles.” Correct this
by rotating the idle needle valve
clockwise

‘/4

to

’/z

turn at a time
until the engine transitions smoothly
without hesitation upon opening the
throttle rapidly.

The fuel mixture may be too lean if the
engine stops at the lowest idle position,
or when the throttle is rapidly opened
from idle. Attempt to correct this by
rotating the idle needle valve counter

-

clockwise

’/J

to

’/?

turn at a time until

the engine transitions smoothly without
hesitation upon opening the throttle
rapidly. If the situation

is

not rectified

by counterclockwise rotations

of

the
idle needle valve, turn the idle
needle valve clockwise in

I/a

to

I/z

turn increments.

3.

After obtaining the proper idle

setting, the

low

rpm setting may be

made through the positioning

of

the

throttle adjustment screw, if applicable.

If

not, adjust the idle setting via the

throttle trim of your transmitter.

prior to attempting any adjustments.

2.

Close the throttle slowly and adjust
the airscrew setting by rotating the
airscrew

(89)

counterclockwise to lean
the mixture and clockwise to richen the
mixture.

Note:

The fuel mixture is

too

is rapidly opened from idle. Attempt to
correct this by rotating the airscrew
clockwise

’/d

to

’/?

turn at a time until
the engine transitions smoothly without
hesitation upon opening the throttle

rapidly.

If

the situation is not rectified

NORMAL

ENGINE OPERATION

3. After obtaining the proper idle

setting, the low rpm setting may be
made through the positioning of the
throttle adjustment screw, if applicable.

If

not, adjust the idle setting via the

throttle trim

of

your transmitter.

Normal Engine

Operation

If break-in was accomplished

on

a test
bench your engine may be mounted to
the aircraft and flown. The initial flight
should be performed with the engine
adjusted for a rich fuel mixture.

1.

Your Saito engine should be
securely mounted to the aircraft. There
are many motor mounts available;
however, a high-quality metal mount,
such as those manufactured by Saito
exclusively for Saito engines, is
considered to be the best.

2.

General operating procedures that

will ensure long engine life are:

Do

not

operate the engine with a
‘‘lean’’ mixture.
Regularly check all screws and nuts

on

both the engine and muffler.

After 1 to 2 hours of operation, valve

adjustment may be necessary. Adjust
the valves as shown in the “Engine
Maintenance” section.
The Saito engines are equipped with
a breather nipple (19). It is
recommended that a length

of

silicone tubing be attached to this
crankcase breather nipple (19) and
routed away from the engine
compartment

so

the excess oil can be

expelled outside of the aircraft.

Engine Maintenance

Do

not needlessly dismantle your

Saito single cylinder engine.

If you must disassemble your single
cylinder engine, please refer to the
following steps. Remember, a qualified
individual should do disassembly.

1.

Cylinder screws should be loosened

in a criss

-

cross pattern.

2.

Assemble the cam gear lining

up

the

timing mark at the

“6

o’clock’
position. The crankshaft must be
positioned at the

“12

o’clock’ or
“top dead center” (TDC) position
(refer to Figure

I

below).

3.

Reassemble the piston, rod, rocker
arm, pins, pushrod, tappet, etc., in their
original positions. Engine parts are
mated after running the engine and
they must be reassembled as close as
possible to their original position.

4.

Assemble the engine, reversing the
criss-cross pattern used in the
disassembly. Prior to tightening each
of the screws, apply a drop of oil to
prevent thread damage.

Normal engine

maintenance,

such

as
adjusting the valves or carburetor
maintenance,

is

permissible without

voiding the warranty.

If you have
any questions concerning
maintenance procedures, please
contact the Saito Service Center at

(217)

355-9511.

Our technicians will

be happy to advise you

on

maintenance issues.

Valve/Tappet

Gap

Adjustment

After approximately one hour of
operation, tappet gap adjustment may
be necessary. When you check the
valves, lubricate the moveable parts.
Also make sure the screw is in tight
before making adjustments to valves.

Adjust the valves to a clearance

of

.03

mm to

.10

mm

(.002”-

,004”)

using the supplied gauge. The valves
must be adjusted with the engine cold
due

to

thermal expansion.

Note:

Valves must be in the
compression stroke or closed position
as shown in Figure

2

below. When

adjustment

is

completed, make sure

you tighten the lock nut.

CARBURETOR MAINTENANCE

Carburetor
Maintenance

Should you experience difficulty with
the carburetor of your engine:

1.

Check that the slotted head

of

the

Idle Needle Valve

(89)

is flush with
the throttle arm housing. This will
put the idle needle back to the factory
preadjusted position.

2.

Remove the high-speed needle

(85)

and flush out the spray bar with

clean fuel. Replace the high

-

speed
needle and follow the instructions in
the Carburetor Adjustment section.

3.

Always use a high

-
quality 4-cycle glow plug.
Saito

SS

(SAIP

recommended.

Tips For Extended

Engine Life

To

add longer life

to

your Saito
engine, the following
recommendations are made:

1.

Use a high-quality fuel containing

20%

lubricants.

2.

Use recommended glow plugs.

3.

Use the proper propeller size and

balance the propeller prior

to

use.

4.

Use a tachometer for precise

engine adjustments.

5.

Use an “after-run”

oil

when you’re

finished flying for the day. Hangar

9

After Run fuel is recommended.

6.

For long-term storage, make sure

there is no

fuel

left

in the tank and the

engine. Remove the glow

plug(s)

and

apply several drops of high-quality

light oil (e.g., a good quality light
machine oil or Marvel Air

Tool

Oil)

to

the top

of

the engine, into the glow

plug hole, down the

pushrod

tubes,
and through the crankcase pressure
vent (breather nipple). Rotate the
crankshaft several times. Store the
engine in the box or on the airplane
with the nose down in order

to

keep

oil in the bearings.

TROUBLESHOOTING

11

Troubleshooting

Generally speaking, there are very
few things that will keep today’s
modern glow engines from starting.

To

that end, make sure you’re using
good quality “fresh” fuel, there are
good glow plugs installed, and the
starting battery is charged and in good
condition. Should the engine fail to

start after these items are verified,
refer

to

the following troubleshooting
