4.2.11 Hold the cylinder with a firm strap band or mount it in a tank vise. Use normal precautions, so that
the surface of the cylinder is not marred or damaged. Use a good 10” or 15” adjustable wrench to grip the
wrench flats on the RaZor body tightly. You can also use an HP Port Wrench. Apply a counter-clockwise
force to remove the RaZor from the cylinder. (See Photo 2)
4.2.12 Remove the valve thread O-ring (17) from the RaZor and discard it.
4.2.13 Use a 6” adjustable wrench to remove the Dip Tube (16) from the Body (14). Remove and discard
the Filter (15) from the Body.
4.2.14 Remove the Cap (2) from the Body (14). It should be hand-tight from step 4.2.3. Remove any
Spacer(s) (8), the Spring (7) and the Piston (4) from the Cap. Remove and discard the O-rings (3, 5) from
the piston. Whenever possible, try to remove the O-rings by pinching them with the fingers and rolling them
out of the groove.
! WARNING !
If a sharp pick is used to remove the O-rings, it should be made from soft brass, not
steel. ANY scratches left in the groove when removing O-rings will cause leaks (bubbling out of the
Cap ambient pressure ports) and the piston will have to be replaced to stop these leaks.

4.2.13 Remove the Seat (6) from the Piston (4) by
pushing it out with a 1/16” drill bit. Place one end of
the drill bit on a flat hard surface. Lower the large end
of the Piston over the drill bit until the flat end of the
drill bit rests against the back side of the Seat. Push
the Piston firmly down straight on the drill bit, until the
seat is pushed out of the piston. Discard the old Seat.
