SettinG the triGGer
There are three adjustment points on the 
trigger
 – the 
front stop trigger screw
, the 
rear stop trigger screw
 and 
the 
spring return strength screw
.
 As standard each Etha 
comes with a factory set trigger travel of  approximately 
6mm in total length; 3mm of  travel before the firing point 
and 3mm of  travel after the firing point.
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  travel 
(See 
fiGure 10A)
.
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 10b)
. 
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
