(6) Wipe off the nozzle and gun body and remove paint and dirt using solvent soaked cloth. To clean
a flat spray nozzle, remove its air guide and to clean the round spray nozzle remove its air cap.
Whenever coating work is curtailed, close the material adjusting valve on the gun body to
prevent any chance of paint flow.
To clean the nozzle and air cap, direct the gun head downward to prevent cleaning solvent
from finding a way inside the gun.
After cleaning, do not immerse the gun, cable or hoses in solvent. This equipment should be
considered as an electric instrument. Continuous dipping in solvent may cause degradation
of the durability and will damage the equipment due to solvent penetration.
If a two component paint or other chemically curing products are used, the same steps as
indicated in the next clause must be taken frequently depending on curing conditions.
4. Finishing operation (When re-starting within24 hours is not expected. )
(1) Switch off power to control unit.
(2) Lower atomizing air pressure to 0MPa.
(3) Take the suction pipe from the paint container.
(4) Lower the air pressure to the supply pump (approx. 0. 1PMa), allow the paint remaining in the
pump to bleed through the return.
(5) Pull gun trigger to reduce paint pressure remaining in hose and gun.
(6) Flush cleaning solvent through the system until the fluid passages are clear of paint.
(7) Pull gun trigger to reduce pressure from the cleaning solvent and to flush the gun and hose.
(8) Turn off air to the pump and release the remaining pressure from the gun.
(9) Wipe off nozzle and gun body using a solvent soaked cloth. Remove the nozzle from gun body
and clean the seating parts between the gun body and nozzle.
The cleaning and flushing should be started at least 10 seconds after switching off the control
unit. It should be noted that over 90% of fire accidents in electrostatic systems occur during
cleaning and flushing. Be sure to switch off the control unit before cleaning. An approved fire
extinguisher should be available.
Never wear gloves without a hole in the palm to handle the spray gun. Never wear rubber
soled shoes during operation of an electrostatic gun. The gun grip is at zero potential if the
control unit is grounded and there is no danger of electric shock if the gun grip is held by a
bare hand.
(10) For the disposing the waste solvent, recover and reuse the waste solvent by use of solvent
recovery system, or dispose them through the waste disposal company in accordance with lows
and regulations.
