Magnum Venus Plastech Gel Coat Gun EMG-1500 - Manual (Page 7)

Filtered air will allow the pump to operate more efficiently and yield a longer life to
operating parts and mechanisms.
A filter capable of filtering particles larger than 50 microns should be used.
Maintenance: If the pump is to be inoperative for a lengthy period of time (even for a
few hours) disconnect air and relieve all pressure from system.
Periodically flush pump with a solvent that is compatible with the material being
pumped. Pour a little throat seal lubricant into the solvent cup to keep upper packings
pliable and to keep material drag-thru soft. Material drag-thru that is allowed to harden,
will score the piston rod. This will create excessive leakage and rapid packing wear.
Disassembly should be done on a clean work bench with clean cloths to keep parts
clean.
If replacement parts are necessary, consult Parts List for identification.
Before assembling, lubricate parts where required. When assembling O-rings, or parts
adjacent to O-rings, care must be exercised to prevent damage to O-ring and O-ring
groove surfaces.
If you have any questions about safety or procedures, contact your Magnum Venus
Plastech
’ representative.
CAUTION: Materials and solvent being pumped must be compatible with the parts of
the pump that becomes wetted when in contact with material or solvent. Wetted parts
consist of the following: stainless steel, copper, brass, steel, gray iron, leather, Teflon
and Vellumoid.
CAUTION: Keep solvents away from heat, sparks and open flames. Keep containers
closed when not in use.
