(4) Adjustment of Amount of Throttle Servo and Air Valve Angle
Move the throttle stick on the transmitter to slow and then full high. If there is excessive or
insufficient opening of the air valve, adjust the opening with the throttle angle adjustment
function (ATV). Confirm that the servo is not subjected to an excessive load due to tugging or
pulling. An excessive load on the servo can cause the battery to discharge and air valve to
lock.
(5) Engine Cutoff Adjustment
When using a transmitter equipped with an engine cutoff function, switch the transmitter to the
engine cutoff position and adjust the air valve so that it is fully closed at that time. Confirm that
the servo is not subjected to an excessive load due to pulling.
(6) Confirmation of Throttle and Air Valve Operation
When the stick is in the slow position: The rotor mark should be located at the slow mark of the
body. When the stick is in the center position: The rotor mark should be located at the center
position of the body. When the stick is in the full high position: The air valve should be fully
open. Recheck these positions.
(7) Lmt Setting
The movement of engine control has considerable significance with respect to the injection
operation. Since there may be errors in operation depending on the direction and movement
always make sure to perform the Lmt setting.
Turn on the power switch and press the function key on the EC-1 to display the Lmt Low
display.
First move the throttle stick on the transmitter to the full slow position and then press either the
data (+) key or data (-) key once. The display changes from Lmt Low to Lmt High.
Next, move the throttle stick to the full high position and press either the data (+) key or data (-)
key once. Lmt Low is displayed. Repeatedly move the throttle stick between the slow and fully
high positions and confirm the display of the mark. This completes the setting procedure. The
settings are stored in the memory of the EC-1. Memory contents remain intact even if the power
is turned off.
(Repeat steps (1) through (7) when the throttle linkage has been changed.)

Engine Starting and Air-Fuel Mixture Adjustment
(1) Turn on the power of the transmitter and then turn on the power of the receiver.
Press the function key on the EC-1 and display the limits. Confirm that Lmt Low is displayed
when the throttle stick is in the full slow position, and that Lmt Low is displayed when in the
full high position.
(2)
Confirm that the rotor mark on the air valve is located at the center mark on the air valve body
when the throttle stick on the transmitter is in the center position.
(When the settings of (2) and (3) are unable to be made, repeat linkage of the throttle servo
and air valve as well as the initial settings.)
(3)
Check that the injection trim is at +0%. After confirming that the dial of the injection trim
adjustment function (spare channel dial) is at the 0 position (center position), display TMD ATL
of the trim mode of the EC-1, and press either the data (+) key or data (-) key to switch to TMD
Fine.

Note:
This injection system was developed for use in model airplanes. All adjustments are not
performed automatically. Always make sure to check all adjustments prior to use.
