Gun Assembly Instructions
The gun assembly procedure, as described, is the factory recommended method. MVP will
not be responsible for any damage to unit if the recommended procedure is not followed.
Components are first assembled to form subassembly units. The subassemblies are in
turn assembled to complete gun assembly. This procedure simplifies the assembly
process.
This assembly applies for all HIS ’80 gun systems (Chopper, Gelcoat, Casting, Saturator or
Hydrajector). The exploded drawings should be used in conjunction with these instructions.
CAUTION: Do not lubricate any part of this assembly that comes into contact with MEKP.
Gun Head Subassembly (’80 Model)

Very gently tap seat down until it bottoms out in nozzle chamber. Do not distort
