User's Manual
SETTING THE 
TRIGGER 
The Ego8 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 48).  
There are four adjustment points on the trigger – the Front Stop 
Trigger Screw
, the Rear Stop Trigger Screw, the Magnet Return 
Strength Screw
 and the Micro Switch Activation Screw.
As standard each Ego8 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 7.1).
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 7.2).
