Maintenance - Accuspray VMX Owner's Manual

Daily Maintenance
Your Accuspray HVLP Gun is made from cast
aluminum, and it contains aluminum components.
Certain solvents containing Methylene Chloride and
Trichloromethane are not chemically compatible with
aluminum. If you are in doubt whether a coating or
solvent is compatible, read the Material Safety Data
Sheet, or contact your material supplier.
It is very important to clean your gun and cup after
every use. The fluid passage can be cleaned by
adding a small amount of solvent to a clean cup,
pressurizing the cup, and triggering the gun. Do this
with the air cap removed so you may recapture the
spent solvent for proper disposal.
The air cap should be cleaned by soaking, or by
using a soft brush. Never use a hard tool that may
damage the air cap holes. Clean the air cap holes
with a wooden tooth pick or pipe cleaner. The
smallest amount of damage to the air cap holes can
effect the spray pattern.
Your gun and cup may be cleaned in a gun washer.
Limit the time in the gun washer to a maximum of 5
minutes. Some solvents may enter the through the
air inlet fitting. This will not damage the gun, and the
excess solvent may be blown out with air.
Lubrication
After every cleaning of the gun, you should lubricate
the moving components. Lubricate with Accuspray
Gun Lube P/N 91-170.
Component Replacement
With regular cleaning and lubrication, complete
disassembly of your gun should seldom be required.

Maintenance

When it becomes time for a complete overhaul, or a
part requires replacement, please follow these
instructions:
General
Close your air source down. Remove the air hose
from the gun. Dispose of any unused paint, flush
and clean the gun.
Atomizing Set
With the retaining ring and air cap removed, pull and
hold the trigger, unscrew the fluid nozzle using your
Accuspray Gun Wrench and remove the fluid nozzle.
Release the trigger and unscrew the needle tip with
your fingers. Remember to retract the needle when
re-installing the fluid nozzle.
To remove the needle shaft, unscrew and remove
the needle adjustment screw and the needle
adjustment spring. Pull the needle out of the gun
with your fingers. If the needle does not pull out
freely, loosen the packing nut. Your gun wrench will
accomplish this with the trigger still attached to the
gun.
Trigger Removal
Locate the 2 E-clip's on the side of the trigger. Slide
them off with a flat-blade screwdriver. The trigger
pivot pin (upper), and the trigger pin (lower) will now
slide out. The trigger is now free to be removed.
Packing Nut Spacer and Packing
Unscrew and remove the needle adjustment screw
and the needle adjustment spring. Pull the needle
out of the gun with your fingers. If the needle does
not pull out freely, loosen the packing nut. Remove
the packing nut with your gun wrench. The
compression spring, spacer, needle guide, and seal
should fall freely from gun. If you experience
difficulty with removal, remove trigger pin and firmly
tap the rear of the gun on a block of wood. Then
remove the seal with an o-ring pick or similar narrow
instrument.
