Internal Washing of Paint Lines
Remove the brass plugs from the bottom of the 3-way valve
and the internal wash bulkhead (see Fig. 3 & 4). Install
a female fluid quick coupler with 1/4 in. npt male threads
(suitable for lacquer thinner) into the bottom of the 3-way
valve. Install a female fluid quick coupler with 3/8 in. npt
male threads (suitable for lacquer thinner) into the internal
wash bulkhead. Connect the paint line to the couplers.
Face the pointer of the 3-way valve down and operate the
gun washer.

Operating the Gun Washer
r
r
1 Make sure all wire trigger locks and other accessories are inside the gun washer tank.
2 If washing only one set of equipment, place empty cans over the unused nozzles and/or stem supports to prevent
solvent spray from hitting the underside of the gun washer lid.
3 Close the gun washer lid.
4 Turn the timer knob clockwise 90 degrees to start the gun washer. The gun washer will run for 90 seconds. Turning
the timer knob less than 90 degrees will reduce the timing cycle. Paint equipment will clean in 60 to 90 seconds.
5 If the lid is opened prior to the end of the timing cycle, the safety air cutoff switch will stop the gun washer. The gun
washer will start again when the lid is closed if time remains on the timer.
Note: Open the lid slowly to minimize solvent vapor escape.
6 Remove the equipment from the gun washer and wipe off any remaining solvent. The gun hanger on the front of the
stand can be used to dry the guns.
Operation
Preventive Maintenance
1 Drain excess paint from cup or pot before placing in gun washer.
2 Drain paint sludge from gun washer tank weekly. Do this after a weekend so that it has settled. Open ball valve and
drain until clear solvent flows. Add solvent to 1” above intake filter.
3 Remove the filter bowl and check the filter inside the regulator for excess buildup approx. every 6 months.
4 Change solvent completely when objects being cleaned become tacky to the touch.
5 Clean inside of tub and intake filter before filling with solvent.

1
Make sure the air line is properly connected with 90-120 psi.
2
Make sure lid is fully closed. Make sure the limit valve (#M1C) on
the valve bracket (#M1SA) is closed in the downward position.
3 Check all air connections to ensure that there are no leaks.
4 Make sure timer cam is engaging the limit valve (#M1C) on the
pump housing assembly.
5 Make sure timer is on and functioning correctly.
2 Make sure the air line is properly connected with 90-120 psi.
3 Check all air connections to ensure that there are no leaks.
4 Drain filter/regulator of water. See number 3 of PREVENTIVE
MAINTENANCE.
5 Make sure there is 5 gallons of clean solvent in the gun washer.
The solvent should be an inch above the intake filter (#70).

6 Make sure lid is fully closed. Make sure the limit valve (#M1C) on
the valve bracket (M1SA) is closed in the downward position.
7 Make sure manifold nozzles and stem supports are not clogged.
Make sure timer cam (#M230-001A) is moving. If its not, slightly
loosen the nuts holding the limit valve (#M1C) on the top panel of the
