CLEANING THE LOW 
PRESSURE REGULATOR (LPR)
The inline regulator can be removed if  needs be. 
Unscrew the LPR cap from the marker body 
(SEE FIGURE 19A). 
Remove the LPR piston and rear spring from the LPR 
cap 
(SEE FIGURE 19B).
Cupping the palm of  one hand, turn the LPR cap 
upside down and tip the front spring out into your 
palm 
(SEE FIGURE 19C).  
Remove the rear spring from the LPR piston and 
using a dry cotton bud, carefully clean the 013 NBR 
70 o-ring on the LPR piston 
(SEE FIGURE 19D). 
If  the o-ring is damaged then replace it. If  the seal in 
the tip of  the LPR piston is damaged then the entire 
LPR piston will need to be replaced. Once the seal 
has been cleaned, lubricate with a light application of  
Eclipse Grease so that it is ready for re-assembly.
DE-GAS YOUR MARKER, DISCHARGING ANY 
STORED GAS IN A SAFE DIRECTION, AND REMOVE 
THE BARREL, LOADER, AIR SYSTEM AND ANY 
PAINTBALLS TO MAKE THE MARKER EASIER AND 
SAFER TO WORK ON.
