Shutdown and Equipment Care
(1) Check the equipment and hose for leak from joints.
1. Interruption or overnight shutdown with resumption due in 24 hours
①
Leave the equipment filled with fluid.
In this case, because air will be purged from the fluid passage keeping the fluid in the way as
if it were stored in a paint can, the fluid in the equipment will be kept free from solidification.
2. Long-term shutdown for a period beyond 24 hours
When you use a kind of paint that precipitates rapidly or one that is of high
viscosity, flush the equipment in accordance with “Equipment Flushing
Procedure” on page 11 when you shutdown the equipment.
②
Completely remove fluid from the equipment and keep it empty.
Any fluid paint left inside the equipment, how little it may be, will solidify.
Flush thoroughly with solvent.
When you flush, keep the solvent pressure as low as possible (the minimum
pressure enough for flushing).
For a short-term equipment shut-down with resumption due in 24 hours, leave
the equipment filled with solvent until you use the equipment again.
Do so each time you shutdown the equipment. It doesn’t do any harm to the
equipment but keeps it in a good operating condition.
(2) Take the nozzle off the gun. Wipe the nozzle mounting surface on the gun with a solvent-soaked
rag. Then clean the nozzle (you may dip it into solvent for a while for cleaning).
(3) Set the airless nozzle in the reversed direction with the rear end facing the nozzle cleaner, then
loosen the nipple letting air jet out blowing out the materials that clogged the nozzle.
Please exercise extreme care when cleaning or replacing the nozzle. Bring the
pressure down following the “Pressure Relief Procedure” and then take the
nozzle off. It is quite dangerous to try to remove paint stuck in the nozzle
unless the pressure is completely removed, with the trigger locked.
Follow the procedure described below to relief pressure.
<<Pressure Relief Procedure>>
①
Lock the trigger.
②
Shut off air supply by turning the pressure control dial counter-clockwise, bringing
down the pressure all the way.
③
Relive the ball cock, bring down the system pressure to zero.
Unlock the trigger and pull it for double-checking.
④
Lock the trigger again.
●
When the nozzle or hose is clogged or when it is suspected that some pressure still
remains after going through the “Pressure Relief Procedure,” slowly loosen the chip
guard mounting nut or the connector at hose end, gradually releasing the pressure
until it is completely relieved. Then inspect the nozzle and hose.
(4) Clean the material filter when the day’s work is done.
Before you take parts apart, always drain all paint fluid from the system and
relief the pump operating pressure down to zero.
(5) Operate the “three-way ball cock” when you have to bring down the pressure instantly, for safety
reasons. However, to relive the paint fluid pressure down to zero, open the “ball cock.”
