To prime the SuperGun, turn the Primer Rod Crank #12 clockwise until it becomes difficult to turn.
IMPORTANT! Over-tightening the Primer Rod Crank #12 can damage and/or collapse the
Primer Rod Assembly #9.
3. Inspect the Giant Buttonhead Coupler #13H for damage and contaminates. Clean using a mild solvent
and a clean cloth if required before attaching to a fitting.
4. Set the Release Valve #13G in its opened position.
5. Attach the Giant Buttonhead Coupler #13H to a buttonhead fitting on the valve being serviced.
IMPORTANT! ALWAYS follow the valve manufacturer's recommendations and instructions
when servicing each type of valve.
WARNING! Always inspect the buttonhead fitting before attaching the Giant Buttonhead
Coupler #13H and keep a watchful eye out for dangerous two piece buttonhead fittings. Ensure
that you have all the proper tools, procedures & product readily available should a problem arise.
6. Release the Handle #5 from the Handle Clasp #11.
7. Lift the Handle #5 up until it reaches it full height.
Allowing the Handle #5 to rest a second while at its full height allows more product to enter the
piston cavity.
8. Pull the Handle #5 all the way down. Steps 7 and 8 together make one stroke.
When fully primed, the SuperGun will operate for 50 to 75 strokes before additional priming is
required. However, as the number of strokes increase the longer it will take for the piston cavity to
fill. For this reason it is common practice to prime the SuperGun every 25 to 50 strokes.
Many operators will rest the Head #6 on the pipeline or the valve to ease in the operation of the
SuperGun.
9. By stroking the Handle #5, product gets injected into the valve and pressure will begin to build. It could
require 10 to 15 full strokes before the pressure begins show on the High Pressure Gauge Assembly
#13C. As you stroke monitor the injection pressure.
NOTICE: Once you become familiar with reading the gauge properly you will be able to
judge when sealant begins to enter the valve. Consult "The Digital HANDBOOK of Valve
Lubrication & Maintenance" for more information on Pressure Gauge Reading
Techniques.
Watch for signs of leakage between the Giant Buttonhead Coupler and the valve fitting, once a
positive seal is achieved gauge pressure will begin to climb.
10. Once the required amount of product has been injected into the valve, slide the Giant Buttonhead Coupler
#13H off the fitting.
To slide the Giant Buttonhead Coupler #13H hold the Hose Assembly #13 near the coupler, tilt
down at slight angle and push off. Do not use excessive force.
Under normal conditions the Giant Buttonhead Coupler #13H can be removed relatively easily as
the pressure on the High Pressure Gauge Assembly #13C drops and returns to a near zero
reading. Occasionally additional force is required, place one hand over the Giant Buttonhead
Coupler #13H and press down as you slide it off. Be careful not use excessive force.
11. If the Giant Buttonhead Coupler #13H is difficult to remove from a fitting, turn the Release Valve #13G to
the Vented Position.
Be very careful to keep fingers and hand away from the vent hole on the side of the Release
Valve #13G when opening. Product will shoot out the vent hole at extremely high pressure.
