The Micro Switch Activation Screw is used to adjust the 
point in the trigger pull at which the micro-switch is 
activated. Turn the screw clockwise to decrease the 
amount of trigger travel to the activation point. Turn 
the screw counter clockwise to increase the amount of 
trigger travel to the activation point (SEE FIGURE 6.4).
The Spring Return Strength Screw can only be adjusted 
by first removing the frame from the marker body, as 
per the instructions in the Maintenance section on 
page 63. The Spring Return Strength Screw is used to 
adjust the spring strength that returns the trigger to its 
resting position. Turn the screw clockwise to increase 
the amount of spring return strength in the trigger 
pull. Turn this screw counter clockwise to reduce the 
amount of spring return strength in the trigger pull. 
Do not turn the screw too far counter clockwise or 
there will not be enough force to return the trigger 
consistently (SEE FIGURE 6.5).
When setting the trigger it is important to ensure that 
the electronic trigger detection is working correctly. 
When the trigger is fully depressed the Trigger 
Detection Indicator (TDI) should point upwards   
  . When the trigger is fully released the TDI should 
point downwards    . For more information, 
see Understanding the Trigger Detection Indicator 
(TDI) on page 25 and The Filter Menu on page 46.

SETTING THE TRIGGER 
The Ego9 provides the user with the option to use 
either a Micro-Switch or an Opto Sensor as the means 
for detecting trigger pulls. Before you begin to adjust 
and set your trigger, you must first select the method 
of trigger detection that you wish to use by entering 
the Set-Up Menu and making your selection from the 
Hardware Menu (see page 52). 
There are five adjustment points on the trigger – the 
Front Stop Trigger Screw, the Rear Stop Trigger Screw, 
the Magnet Return Strength Screw, the Micro Switch 
Activation Screw and the Spring Return Strength Screw.
As standard each Ego9 comes with a factory set trigger 
travel of approximately 2mm in total length; one 
millimeter of travel before the firing point and one 
millimeter of travel after the firing point, and the trigger 
detection method set to Opto.
The Front Stop Trigger Screw is used to set the amount of 
trigger travel prior to the marker firing. Turn this screw 
clockwise to reduce the amount of travel. Do not turn 
the screw too far or the trigger will be pushed past 
the firing point and the marker will not work. Turn this 
screw counter clockwise to increase the amount of 
trigger travel (SEE FIGURE 6.1).
The Rear Stop Trigger Screw is used to set the amount 
of travel after the marker has fired. Turn this screw 
clockwise to reduce the amount of travel. Do not turn 
the screw too far or the trigger will be prevented from 
reaching its firing point and the marker will not work. 
Turn this screw counter clockwise to increase the 
amount of travel (SEE FIGURE 6.2).
The Magnet Return Strength Screw is used to adjust the 
amount of force with which the trigger is returned to its 
rest position by the magnet. Turn the screw clockwise 
to increase the amount of force. Do not turn the screw 
too far or it will negate the position of the Front Stop 
Trigger Screw. Turn the screw counter clockwise to 
reduce the amount of force. Do not turn the screw 
too far or there will not be enough force to return the 
trigger (SEE FIGURE 6.3).
