Troubleshooting

SYMPTOM CAUSE CORRECTIVE ACTION

Figure 3

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, that there are good glow

plugs installed and that the starting battery is charged and

in good condition. If the engine has been performing

well, but begins to loose power or becomes difficult to

start, check the valve clearance. Should the engine fail

to start after these items are verified, refer to the

following troubleshooting chart (Figure 3 shown above)

Support Equipment

Glow Plug Wrench

The Hangar 9

Long Reach Plus Wrench (HAN2510)

is an excellent wrench to access, remove, and tighten

glow plugs.

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 Power Pro (HAN162) Starter will work

perfectly on all Saito engines.

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.

Glow Plug Battery

Your glow plug may be properly heated by several

defferent 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.

Engine Parts Identification

It is important to be able to identify the parts of your

Saito FA-200Ti engine. A chart that includes the part

number and description of the various parts is provided.

This is to assist you in easily identifying the respective

parts of the FA-200Ti engine. A chart with call outs of

various parts is provided below.
