Although explained here, regulator service should only be performed by a GOG Paintball
TM
trained airsmith.
With the marker unloaded and de-gassed, unscrew the regulator from the marker and remove the grip
frame following the instructions in this manual. Take care not to lose the filter screen that sits inside the
vertical regulator’s ASA connection.
Using a pair of snap-ring pliers, remove the snap-ring from the bottom of the regulator and slide the
regulator off the swivel. This is the preferred way to separate the regulator from the hose and bottomline
ASA because it does not disturb the sealed hose fittings and is not likely to cause a leak.
Using a 7/16 open end or adjustable wrench, engange the wrench flats in the sides of the spring platform
and remove it from the bottom of the regulator body. The regulator spring will now be free to fall out into
your hand. The brass regulator piston may be removed by tapping the regulator body against a table top
or solid, but soft surface such as a block of wood.
At this level of disassembly, the seal in the end of the piston and the regulator body may be inspected,
cleaned with a soft cloth or cotton swab, and replaced if necessary. If the regulator seal shows signs of
damage, it may be removed and flipped over so that its back side is used instead. If both sides of the seal
are damaged, it must be replaced. Lightly lubricate all o-rings with GR33SE
TM
for reassembly.
Do not lubricate the regulator seal at the end of the piston.
