Technical information

All exterior surfaces of the A.I.R. valve assembly should be cleaned. The bolt and bolt bumper (large o-
ring at the base of the power tube) should be removed from the power-tube and cleaned. The outer surface
of the power tube should be cleaned.
The interior of the body can also be cleaned at this time.
To lubricate the air valve, it is recommended that you use Pro-Lube or Autolube, oils which have been
specifically designed for this gun.
Turn the A.I.R. valve assembly upside down and locate the two holes in the body which are labelled 'OIL'.
Lubricant can be placed in either of these holes. Place two or three drops of lubricant into the A.I.R. valve
assembly.
NOTE: Excessive lubrication can adversely affect the performance of your gun by allowing dirt to
accumulate in the valve.
3-3 Complete Disassembly
General Procedure: Always disassemble your 68Micromag using a clean, well-lit, flat surface. Lay the
various parts out in order as they are disassembled, as the gun will be re-assembled in the reverse order.
Refer to Diagram () for the following sections.
(1) Removing the A.I.R. Valve
Disconnect the hose fitting which is attached to the valve port if it is a quick-disconnect fitting. If there is
no quick-disconnect, the hose will have to remain in place, but it is flexible enough to allow you to remove
the valve.
Remove the Field Strip screw located on the back of the body underneath the valve.
Grasp the A.I.R. assembly and pull it towards the rear of the gun, pulling the trigger at the same time.
Once the A.I.R. has moved as far as it will go, slightly rotate the valve counter-clockwise.
Pull the A.I.R. valve assembly the rest of the way out of the gun body.
(2) Removing the ON/OFF assembly
Grasp the on/off top and pull the assembly up and out of the valve.
Look inside the on/off chamber to determine if either of the on/off bottom o-rings have remained in the
chamber.
Lightly tap the chamber or use a small pick or allenwrench to remove any o-rings which remain in the
chamber.
(3) Disassembling the ON/OFF assembly
Separate the brass on/off bottom from the stainless steel on/off top. Note, this will cause any o-rings which
remain attached to the on/off pin to fall off.
Pull the on/off pin out of the on/off top.
(4) Disassembling the Regulator
Unscrew the rear portion (regulator) of the A.I.R. valve from the forward portion (valve).
Remove the regulator seat (disc-shaped o-ring).
Remove the regulator pin and regulator pin spring (both should pull out together; a pick may be required to
remove the spring).
Unscrew the velocity adjusting nut.
