PREVENT STATIC SPARKING
Always be sure
all
equipment and objects being sprayed
are properly grounded. The high velocity flow of fluid
creates static electricity.
Sparks may cause fire or explosion.
Use
only conductive or grounded fluid hoses for airless
applications.
Be
sure that gun
is
grounded through hose
connections.
Once each week, check electrical resistance of hose
(when using multiple hose assemblies, check overall
resistance). Overall (end to end1 resistance of unpressurized hose must not exceed
29
megohms (max.)
for any coupled length or combination of hose lengths.
If hose exceeds these limits, replace
it

Plug

When flushing equipment, remove spray tip, use the
lowest possible pressure, and maintain firm metal to
metal contact between gun and metal waste container.
This reduces the chance of static sparking.
Follow the coating and solvent manufacturer's safety
precautions and warnings.
