Maintenance
To reduce the risk of an injury, follow the Pressure
Relief Procedure and the Fluid Voltage Discharge
and Grounding Procedure before doing any
maintenance on the gun or system.
Daily Care and Cleaning
Checklist
Check the following list daily upon completion of equip-
ment usage.
Flush the gun. See Flushing, page 26.
Clean the fluid and air line filters.
Clean the outside of the gun. See Clean Out-
side of Gun, page 27.
Clean the air cap, spray tip, and tip guard
daily, minimum. Some applications require
more frequent cleaning. Replace the parts if
they are damaged. See Clean the Spray
Gun, page 27.
Check the electrode and replace if broken or
damaged. See Electrode Replacement on
page 40.
Check for fluid leakage from the gun and fluid

Flushing

• Flush before changing fluids, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
• Flush at the lowest pressure possible. Check con-
nectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
To reduce the risk of fire, explosion, or electric
shock, turn off the turbine air (TA) before flushing the
gun.
Follow the Fluid Voltage Discharge and Grounding
Procedure, page 22, before flushing.
Only flush, purge, or clean the gun with fluids that
meet the following flammability requirements:
FM, FMc Approved:
Material does not sustain burning in accordance with
the Standard Test Method for Sustained Burning of
Liquid Mixtures, ASTM D4206.
CE-EN 50059 Compliant:
Materials which cannot be ignited, in any mixture with
air, by an energy source of less than 500mJ.
NOTICE
Do not use methylene chloride as a flushing or
cleaning solvent with this gun as it will damage nylon
components.
1. Turn off the turbine air and wait 30 seconds for the
voltage to bleed off.
2. Discharge the system voltage. See Fluid Voltage
Discharge and Grounding Procedure, page 22.
3. Follow the Pressure Relief Procedure, page 22.
4. Remove and clean the air cap and spray tip.
5. Change the fluid source to non-flammable solvent.
6. Trigger the gun to flush the fluid passages clean.
