CLEANING THE 
BREAK-BEAM SENSOR 
SYSTEM
Undo the retaining screw for the Break-Beam Sensor Cover on 
the left hand side of the Ego8 using a 5/64" (2mm) hex key (SEE 
FIGURE 9.1).
Remove the Sensor Cover to expose the back of the Break-Beam 
Sensor  unit  (SEE  FIGURE 9.2).  Using a dry cotton bud,  carefully 
remove any debris, paint or moisture from the back of the sensor 
unit and from inside the Sensor Cover.
Lift the BBSS free from the Ego8 body and using another dry 
cotton bud, remove any grease or debris build-up from the front 
of the sensor unit (SEE FIGURE 9.3).
WARNING: DE-GAS YOUR MARKER, DISCHARGING ANY STORED GAS 
IN A SAFE DIRECTION, AND REMOVE THE BARREL, LOADER AND AIR 
SYSTEM TO MAKE THE MARKER EASIER TO WORK ON.
