Daily Care and Cleaning

WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of fire and explosion:
D Only flush, purge, or clean the spray
gun with non-flammable fluids, as
defined on the front cover of this
manual.
D Do not flush with the turbine air (TA) to the gun
turned on.
WARNING
ELECTRIC SHOCK HAZARD
Follow the Fluid Voltage Discharge
and Grounding Procedure on page 19
before cleaning or flushing the gun to
ensure the voltage is discharged and avoid serious
injury from an electric shock.
WARNING
PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of an injury, follow the
Pressure Relief Procedure on page 19
when you stop spraying, before installing
or cleaning the fluid nozzle, and whenever you are
instructed to relieve the pressure.
1. Clean the fluid and air line filters daily.
2. Clean the outside of the gun daily with a soft cloth
dampened in a non-flammable cleaning fluid.
3. Clean the air cap and fluid nozzle daily, minimum,
as instructed on page 24. Some applications
require more frequent cleaning. Replace the fluid
nozzle and air cap if they are damaged. See page
36.
4. Check the electrode wire. Straighten it if it is bent
and replace it if it is broken or damaged. See
page 37.

Maintenance

Fluid in the air passages could cause the gun to
malfunction and could draw current and reduce
the electrostatic effect. Fluid in the power supply
cavity can reduce the alternator life. Whenever
possible, point the gun down while cleaning it. Do
not use any cleaning method which could allow
fluid into the gun air passages.
Do not point the gun up while cleaning it.
Do not immerse the gun in fluid.
Do not wipe the gun with a cloth that is heavily
saturated; wring out the excess fluid.
5. Check for any fluid leakage from the gun and fluid
hoses. See page 25. Tighten the fittings or replace
the equipment as needed.
6. Check all of the work hangers for a buildup of fluid;
clean them if necessary.
7. Flush the gun before changing colors and when-
ever you are done operating the gun.
