(2) Choke
① Turn on the transmitter.
② Turn on the receiver switch.
③ Turn on the ignitor switch.
④ Close all choke valves of engine.
⑤ Open the valve by 10 degrees from the fully closed position (the first idling position)
⑥ Use the starter until the engine fires or “pop” (see the NOTE below)
⑦ Open the choke valve fully.
NOTE: Listen to the firing or popping sound carefully when you are using the starter to start the engine.
The sound is supposed to hear after using the starter for a few seconds. In case you cannot listen to the
sound, check the above article 9 – 12 again for the initial installation, or check if the article 16. (1) – (2) is set
up correctly. Then go to next step if everything is all right.
(3) Start the engine
① Turn on the transmitter.
② Turn on the receiver switch.
③ Open the choke valves.
④ Open the throttle valve by 10 degrees from the fully closed position (the first idling position).
⑤ Turn on the ignitor switch.
⑥ Inform your assistant or people around you that you are starting the engine.
⑦ Use a starter. Check the above article (2)-(3) procedures above again if it can’t get started for more than
3 seconds using the starter.
Warning:
Start it over than the position of fast idling might cause abnormal extra-output which could make propellers
or rotor move extremely fast. There is a possibility to damage yourself or things.
Attention:
Do not run the starter for more than 3 seconds at a time. Give the starter at least 3-second interval for
continual use. Otherwise the starter, lead wires and battery may get damaged.
(4) Countermeasures when the engine doesn’t start.
Possible reason:
Over rich (over choke) / over lean (not enough choking) the fuel mixture/incorrect throttle opening setting /
the ignition setting up is not done completely (for example, ignition switch is off) .
Follow procedures below:
①
Check the power supply to make sure the switch is on / battery is charged/ wires are not got damaged/
connectors are properly connected etc.
②
Check and make sure if the throttle valve is at the first idling position- not only the position of transmitter
throttle stick/ but also the position of fully opened throttle servo/ fully closed limit position (end point
adjustment)/ the direction of throttle servo movement (NORMAL
⇔
REVERSE).
③
Check and make sure if it is not over choke- Remove the spark plug and check if the center and ground
electrodes get wet with gasoline.
If it does, it is over choke, follow instruction below
1.
Turn off the ignition switch.
2.
Remove the spark plug and the plug cap.
3.
Fully open the chock valve.
4.
Full open the choke valve.
5.
Use the starter around 10 seconds.
6.
Dry the electrodes of the spark plug by a blower, or wipe the gasoline on them with a cloth.
7.
Put the plug procedures on the engine and fit the plug cap on it.
8.
Repeat the above procedures (2)-(3).
④If the electrodes of spark plug are not moist or the exhaust port does not smell gasoline, there is not
enough choking. In case choking is still not enough even if you have repeated the procedures 16. (2) – (4)
②, the trouble may come from malfunction of the system rather than the problem of operation. Check the
article 10 – 11 above, check if the fuel filter is not clogged as well.
