The disassembled drivetrain is on the next page. To maintain your drivetrain, clean and re-lubricate the
following O-rings: bolt switch, keg inner and valve. Also clean and re-lubricate the keg bore, and the inside of
the back of the bolt where the valve O-ring seals, as well as the bolt and the valves themselves.
After working on your drivetrain, reassemble it, and then slide it back into your marker.
If your drivetrain is difficult to install or remove from your marker, use some lube on the outside O-rings of
the drivetrain so they can slide freely.
Over the life of your marker, some of the drivetrain O-rings will wear out, in particular, the bolt switch O-
rings and the valve O-ring. Replacements of these O-rings are supplied with your marker; however, if you
require more, you should use only genuine MacDev O-rings.
Maintaining the inline regulator
Your inline regulator (otherwise known as Gladiator Reg,) regulates the pressure from your air system down
to the pressure used to fire your marker. It is very important that your inline regulator is working well, if not,
you may experience problems with velocity fluctuation or shutdown.
Before working on your Gladiator Reg, make certain that the air supply is turned off (via the venting ASA),
and safely fire any gas out of the gun to ensure it does not have any residual pressure.
Remove the hose from the fitting in the bottom of the Gladiator Reg – you do this by pushing the collar in,
whilst pulling the hose out. Once the hose is removed, you can unscrew the Gladiator Reg from your marker.
Put your marker aside so that you can concentrate on your Gladiator Reg.
A picture of the parts inside your Gladiator Reg are shown on the adjacent page, disassemble the regulator
and clean and re-lubricate the piston and retainer inner O-rings. Also, clean and re-lubricate the bore inside
the top works where the piston slides. Please note that to complete this simple maintenance, you do not
