Disassembly:
WARNING: Always remove fluid pressures before working on the unit.
WARNING: Be careful not to bend the catalyst and resin needles.
Built in shut off valves
The MVP DuraMAX gun incorporates Rapid Access Design (R.A.D.). With fewer parts
and maintenance-friendly access, routine replacements take only minutes. This rugged
gun features a carbide needle and seat (standard), and is the only gun on the market
with built-in shut-off valves for resin and catalyst. Now you can perform maintenance
without the need to drain pressure or remove hoses.
To use the built in shut off valves tighten the catalyst and resin shut off needles into the
fittings to prevent the material from leaking through into the gun head. It is still
recommended to relief the excess pressure by momentarily opening the catalyst
recirculation valve and resin dump valve before working on the gun.
Initial Disassembly . . .
1. Remove Catalyst, Resin and Flush fluid pressure from system before disassembly.
2. Remove Catalyst, Resin and Flush lines from the Gun Block Assembly (DMX-3001-01).
