Operation
Operating the Gun Washer
WARNING
PRESSURIZED EQUIPMENT HAZARD
Do not operate the gun washer with the
lid open. Serious injury, including blind-
ness, could result.
A safety device has been installed to shut off
the pump when the gun washer lid is opened.
Do not tamper with or alter this device.
Open the gun washer lid slowly.
The gun washer lid has been designed to close
automatically unless supported by hand (Models
112634 and 112635) or by foot (Model 117438).
Do not bypass this safety feature by propping
the cover open with an object or by any other
means.
WARNING
EQUIPMENT MISUSE HAZARD
To avoid component rupture, which could result in
serious injury or property damage, never use an air
supply pressure above the gun washer’s maximum
working pressure of 100 psi (0.7 MPa, 7 bar).
Never operate the gun washer at a pressure above
the maximum working pressure rating of the gun(s)
being cleaned.
1.
Set the air pressure to the gun washer between
40–75 psi (0.3–0.5 MPa, 2.8–5.2 bar), using an air
regulator on the gun washer air supply line.
NOTE: All gun washer models include a pump air filter/
regulator that has been preset at the factory; do not
readjust it. See Fig. 4, page 15.
CAUTION
Do not change the setting on the Husky pump’s air
filter/regulator as this will damage the regulator.
2.
Make sure all adapter chains and cables are inside
the gun washer tank.
3.
If one or more of the gun mounts is not being
used, place a stream blocking device, such as a
pint-size can, over the stem supports and the cup
spray nozzle not being used to prevent those jets
of solvent from hitting the underside of the gun
washer lid.
4.
Close the gun washer lid.
5.
Press the start button on the reset valve block to
start the gun washer. Guns, cups, or other paint
containers will be cleaned in about 30 to 60
seconds.
NOTE: The cleaning operation should not exceed
60 seconds. Longer operation will not improve the
cleaning process and will cause unnecessary wear
on the pump.
If the lid is opened while the gun washer is operat-
ing, the air supply will automatically shut off and
spraying will stop. To restart the pump, close the
lid and press the start button.
6.
Remove the gun from the gun washer and blow or
wipe any solvent remaining on the gun exterior.
7.
Hang up the gun until it is used again.
CAUTION
Always hang the gun with its nozzle pointing down to
avoid having solvent run into the gun air passages.
Solvent in the gun air passages can cause poor at-
omization and can damage the gun.
Pump Operation and Maintenance
See the pump instruction manual provided with the gun
washer for operation and maintenance of the pump.
