AIR LEAKS
AIR LEAKING FROM THE AIRPORT
• Check the o-ring on the air system. If needed
change the O-ring and try again. The O-ring
normally used is #15 but some manufacturers
might use a different size. Consult the manual
of the air system you are using
AIR LEAKING FROM THE HYPER3™ REGULATOR
• First locate the position of the leak.
• For disassembly instructions consult the
technical section under Hyper3™ regulator.
• If the leak is coming from the bottom of the
regulator you will need to disassemble the
regulator and change the #010 O-ring and
the seat on the brass seat retainer mounted
inside the Hyper3™ regulator.
• If the leak comes from the small hole in the
middle of the regulator there are two possible
O-rings. Change the #015 O-ring on the
piston and the #007 urethane O-ring inside
the body of the regulator.
• If the leak is from the top of the regulator
change the #011 O-ring on the outside
of the cap.
• Change the #011 O-ring on the top cap of
the Hyper3™ and apply a small amount of lube
to the O-ring.
AIR LEAKING BETWEEN BODY AND FRAME
• A leak between the body and the frame can be
caused by a couple of things.
• First Check that the Hyper3 reg is not set too
high or too low.
• If above doesn’t help, remove the frame from
the RAIL™ and check the hose connections
between the solenoid and the hose fittings.
• Last possibility is that one of the hose fittings
is leaking. Gas up the RAIL™ without the frame
attached and try to locate the exact point of
leakage. If the leak is coming from one of the
hose fittings, remove the screw, check and
replace any damaged o-rings and re-attach
screw to the body.
AIR LEAKING FROM BACK OF THE RAIL™
• Check that the bolt kit is tightened all the way
into the RAIL™. If the bolt kit is loose, it will
start to leak.
• If above does not solve the leak, remove the
bolt kit and change the #020 O-ring on the
back cap of the bolt kit. Also change the two
#009 O-rings located on the tail of the bolt.
Lube well and re-insert the bolt kit into the
RAIL™. Check bolt kit break down picture on
page 19 for O-ring locations
AIR LEAKING FROM FRONT OF THE RAIL™
• Remove the Bolt kit from the marker and
change the #017 O-ring located inside of the
Can and the #014 O-ring located inside
the Manifold. Lube well and re-assemble.
• If above doesn’t help, try changing the
#020 O-rings located outside of the Can.
Lube well before re-inserting bolt kit.
