Possibility of fire or explosion
<<Sources of ignition>>
Static electricity is generated when the paint runs through the pump or hose.
If parts of the coating machine are not appropriately grounded, electrostatic sparks may be
generated to ignite the volatile component of a solvent, sprayed paint mist, suspending debris or
other combustible substance, possibly resulting in serious injury or damage to the machine.
Check that the coating machine and all peripheral metallic objects and the products to be coated
are grounded. If not, electrostatic sparks may be generated to cause fire or explosion.
Fully ventilate the area where a spraying operation is performed.
Do not bring the high-voltage electrode at the tip of the gun or its surrounding parts into contact
with the product to be coated or ground during an electrostatic coating operation. Unknowingly
using a defective gun may generate big sparks and damage the nozzle and electrode.
Do not insert or remove the power plug into or from the power outlet on the coating machine or
electric equipment within a 7m to 8m radius of the spraying operation area.
Do not perform a spraying operation in the vicinity of an open flame, pilot lamp or other source of
ignition.
Never smoke in the area where a spraying operation is performed.
If you feel electric shock, even slightly, when handling the coating machine, immediately stop the
spraying operation and check the grounded condition of each part.
Do not restart the spraying operation until the cause is located and countermeasure is completed.
If the power cable or connecting cable is damaged, it may generate sparks to cause fire or
explosion. Protect the cables from damage.
An extinguisher with a sufficient capacity must be provided at the area where a spraying operation
is performed.
<<Grounding (earthing)>>
To prevent hazards from static electricity, completely ground the paint pump, coating machine, all
surrounding metallic objects and the products to be coated. If there is no proper grounding object,
ground them according to the methods specified by the technical standards for electric equipment
(class D grounding or equivalent).
The methods for grounding the coating machine are as described below.
□
Grounding of the working floor
The working floor shall be made of a conductive material and grounded.
Immediately wipe the spilt paint and dirt off the floor and keep the floor clean.
□
Grounding of the paint pump
Connect the crimped round terminal at one end of the attached grounding cable to the grounding
terminal on the paint pump body and connect the clip at the other end to a class D grounded
object.
