The user raises the trim. "Ready" will appear on the HDT (Hand Data Terminal) screen when
the engine is supposedly to be to idle. If the trim is on "stop" position, "Trim low" will be read
on the HDT. If higher than idle, "Stick Lo!" will be read.
When "Ready" is displayed, the user raises the stick to full power and to idle again, the start
sequence begins.
GLOW ON if the glow test fails, a "Glow Bad" message is displayed, and the red led blinks.

GAS IGNITION DETECTED PREHEATING AND FUEL RAMP
When the max ignition RPM is reached and the ignit
ion isn’t detected the starter is switched
off and the RPM decays repeating the cycle. Usually the lack of ignition is caused by the glow
plug that doesn’t have enough filaments exposed or too much gas. “Weak Gas” message on
the HDT means not enough gas has entered the combustion chamber to support ignition.
When the thermocouple registers an increase of 50ºC in temperature or it is higher than the
“start/minimum temperature”, it means that the ignition have occurred, the starter is switched
on immediately at reduced power, increasing its power accordingly to the real rotor RPM.
At the same time the engine begins to accelerate at the "fuel ramp" values, depending on the
real RPM. Once the engine reaches the factory preprogrammed RPM’s the gas valve is
closed, and when the RPM arrive at the predefined "starter off" value, the starter is switched
off and the brake applied to it. The engine continues accelerating alone until the idle RPM are
reached.
Always accelerate to full power. Slowly the first time you start the engine, to allow the I.C.S.
learn the full power and idle limits. Do this every time you recharge your batteries.
SHUT DOWN
To shut down the motor at any time, close the throttle trim and the motor will stop and go into
auto-cool until 100°C are reached. The motor will only go into auto-cool if the trim is lowered.
START RECAP!
1. Fill the gas tank.
2. Open the manual fuel valve.
3. Check the voltage on your I.C.S. battery.
4.
Raise the trim the HDT will read “Ready”
5. Raise the throttle to full and back to idle
engine starts… “If not it will go into auto-
restart mode”
6. Shut down... lower the trim
7. If you wish not to start the motor, lower the trim FIRST, then the throttle.
