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

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

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.

precautions and warnings.

Of

Your Sprayer

WARNING

Always shut

the pump and relieve system pressure when you are done spraying for a while, when storing the sprayer, and before adjusting, removing or adding any parts.

To relieve pressure, shut

off

the pump, trigger the spray gun, engage the trigger safety, and open the drain valve.

Check the packing nut/wet cup periodically. The packing nut should be tight enough to stop leakage -no tighter. Use
