Trigger Handle Maintenance Bulletin



Regular and periodic maintenance of the Trigger Assembly is necessary to ensure maximum performance and life of your controller.


As with any mechanical device gradual wear limits its ability to perform it’s designed function. The Trigger Assembly is no acceptation. The trigger mechanism’s sole function is to provide a small accurate signal to the control box to vary the car’s speed and braking. Therefore periodic adjustments are essential.


Trigger Arm Button


The Trigger Arm Button must remain in contact and track level and square across Resistor at all times in order to function properly. An indication of a maladjusted Trigger, causing erratic behavior of the Controller is as follows:


1.        Inconsistent Trigger response when the Trigger is pulled during various points of throttle travel, including reasonable side pressure on the Trigger (the car stutters or the red brake LED comes on before the Trigger is released).

2.        Same as the above under the extreme conditions the Controller may blows the 5A brake fuse.




Note: Exercise extreme care when using tools or sharp objects, damage to the Resistor may occur.


Check the following:  

1.        All electrical and hardware connections are secure.

2.        Tracking residue on the Resistor, clean with a Q tip (Never oil the Resistor).

3.        If the frame is sprung or if there are any bent parts causing the Button to loose contact with the Resistor with normal side pressure.

4.        If the Trigger Oil-lites are worn excessively, replace and lightly oil as necessary.

5.        That the Button is not worn excessively or requires re-facing and/or restore the radius as indicated in the Owners Manual and “Button Repair and Replacement” below.


Trigger Arm Button Replacement


Note: The trigger Arm is a custom modified part P/N TE-21-003-001, contact Third Eye or local Dealer for replacement.


1.        Remove the Trigger Arm Button from the Trigger Assembly.


2.        Carefully install the new Trigger Arm Button into the Trigger Assembly.


3.        Perform the Button Adjustment procedure.



Button Adjustment


If the Button and Trigger Arm are in good condition perform the following as necessary.

Performing this function provides smooth and quite Trigger operation. 


1.        With the Return spring in place, the Button must track level and square with the Resistor as indicated in the Owners Manual, if not carefully bend the Trigger arm at the base until proper alignment is achieved.

2.        Remove the Return Spring. Adjust the Button tension on the Resistor, by bending the Trigger Arm near the base to achieve to # 3-4  at the Arms Button using a “Fiddle Stick” (available at any track) inserted through the rectangular slot in the frame with the Trigger in the ½ throttle position. Repeat step #1,2 as necessary.

3.        Carefully insert a 1”x3” piece of 800 grit sand paper between the Resistor and Button length wise to the Resistor and the abrasive side facing toward the Button.

4.        Holding the sandpaper in place and with slight pressure on the Button, cycle the Button across the full travel of the resistor for about 10 seconds. Repeat if necessary.

5.        Re-verify steps 1,2,3 until the proper alignment and tension is achieved.
