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.
