air supply override valves you must press and hold the priming button before the
pump will move.
NOTE: as resin enters pump you may have to increase PSI slightly in order to maintain
even pump stroke. Observe gun to make sure resin is exiting evenly with no air
inclusion.
2. Shut off air to resin pump by either turning regulator to zero or turning pump air
control valve to off position.
3. Close gun and flush into appropriate container for approximately 2 seconds.
NOTE: Flush by pushing solvent button on side of gun.
4. Repeat opening of gun and aim into appropriate container for catalyst priming. Keep
gun open during priming procedure.
PRIMING PROCEDURE (CATALYST)
1. Slowly fill 2-gallon catalyst jug with MEKP (never dilute catalyst for Magnum Venus
system).
NOTE: See catalyst manufacturer for proper MEKP formulation for your particular
operation.
2. Check to make sure catalyst recirculation valve is open. Open if needed.
3. Remove quick pin from pivot link assembly.
4. Loosen catalyst packing nut slightly to hand prime.
5. Slowly with steady, even strokes, hand pump catalyst pump using rail assembly.
Stop hand priming when steady stream of catalyst exits gun. Close gun and flush
for approximately 2 seconds.
6. Reinstall quick pin into pivot link assembly.
7. Close catalyst recirculation valve on the catalyst manifold.
8. Retighten packing nut. Snug tight only.
9. Slowly open resin pump air valve and slowly turn pump regulator to 15-20 PSI.
Resin and catalyst pump will stroke until system is full. On systems with air supply
override valves you must press and hold the priming button before the pump will
move. Check all fittings for leaks.
10. System is ready for use.
NOTE: Always remember to turn off regulator and slowly open gun trigger to bleed
system fluid pressure before any disassembly or repair takes place.
SHUTDOWN PROCEDURE
1.
Turn resin pump and chopper regulators to zero. Turn resin pump air valve to off
position.
2. Open catalyst recirculation valve on the catalyst manifold.
3. Pull quick pin from pivot link assembly.
4. Remove nozzle, nozzle cap, turbulent mixer and mix housing and injector assembly
from gun head. Clean parts and set aside. Inspect for wear.
5. Aim gun into container and pull trigger until flow of material becomes small trickle.
Release trigger.
6. Push flush button to flush gun head.
7. Check water trap.
8. Check pump packings for leaks. Resin leaking into oil reservoir in center section
cavity indicates packings need tightening or replacement.
