THE LOW PRESSURE
REGULATOR ASSEMBLY
Remove the SL4 inline regulator and foregrip crown as
detailed on page 44.
Push and hold the front of the LPR assembly and the
valve plug back into the LV1 body (SEE FIGURE 20A) . While
continuing to do this, pull the tuning fork out of the LV1 body
(SEE FIGURE 20B) .
Pull the valve plug with attached valve stem out of the LV1
body (SEE FIGURE 20C) then remove the LPR body assembly
(SEE FIGURE 20D) .
Tip the spring and piston out of the LPR bore (SEE FIGURE
20E) (if the LPR piston is held in place by grease stiction, use
some needle-nose pliers to grip the piston and pull it out of
the body. Be careful not to damage the piston tip when doing
this).
Clean and inspect the 013 NBR70 o-ring on the LPR piston, re-
lubricating with a thin layer of grease or replacing if damaged
(LABELLED
A
FIGURE 20F) . Next clean and inspect the piston
tip (LABELLED
B
FIGURE 20F) , if the tip is damaged replace the
piston. Remove any excess grease on the piston, over lubrication of
the LPR assembly can cause adverse effects on performance of the
LPR.
Unscrew the LPR cap from the LPR body (SEE FIGURE 20G) . Clean
and inspect the internal (LABELLED
A
FIGURE 20H) and external
o-rings (LABELLED
B
FIGURE 20H) on the LPR body, replacing if
necessary. Lubricate both with a small amount of grease, using a
small hex key to gently apply grease to the internal o-ring.
DE-GAS YOUR MARKER, DISCHARGING ANY STORED GAS IN
A SAFE DIRECTION, AND REMOVE THE BARREL, LOADER, AIR
