SAFETY WARNINGS
GROUNDING
Ground the sprayer and other components in the system to reduce the risk of static sparking, fire or
explosion which can result in serious bodily injury and property damage.
Alwaysground allof thesecomponents:
•Sprayer: Connect a ground wire and clamp (supplied) to a true earth ground.
•FluidHose: use only grounded hoses.
•Spraygunordispensingvalve: grounding is obtained through connection to a properly
grounded fluid hose and pump.
•Objectbeingsprayed: according to your local code.
• All solvent pails used when flushing should only be metal pails which are conductive.
Once each week, check electrical resistance of hose (when using multiple hose assemblies, check
overall 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 immediately.
Never exceed 500 Ft. (150 m.) overall combined hose length to assure electrical continuity.
Do not use halogenated solvents in this system. The prime valve, 2 gun manifold and most
airless guns have aluminum parts and may explode. Cleaning agents, coatings, paints or
adhesives may contain halogenated hydrocarbon solvents. DON'T TAKE CHANCES!
Consult your material suppliers to be sure. Some of the most common of these solvents are:
Carbontetrachloride,Chlorobenzene, Dichloroethane, Dichloroethyl Ether, Ethylbromide,
Ethylchloride, Tethrachloethane.Alternate valves and guns are available
if you need to use these solvents.

PREVENT STATIC SPARKING FIRE/ EXPLOSIONS
ALWAYS be sure all equipment and objects being sprayed are properly grounded. Always ground sprayer, paint
bucket and object being sprayed. See "grounding" on page 4 for detailed grounding information.
Vapors created when spraying can be ignited by sparks. To reduce the risk of fire, always locate the sprayer at least
20 feet (6 m.) away from the spray area. Do not plug in or unplug any electrical cords in the spray area, this can
create sparks when there is any chance of igniting vapors still in the air. Follow the coating & solvent manufacturers
safety warnings and precautions.
Use only conductive fluid hoses for airless applications. Be sure gun is grounded through hose connections. Check
ground continuity in hose & equipment. Overall (end to end) resistance of unpressurized hose must not exceed 29
megohms for any coupled length or combination of hose length. Use only high pressure airless hoses with static wire
approved for 3000 psi.
WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS OR PAINT
THINNERS:
1.When spraying with flammable liquids, the unit must be located a minimum of 25 feet away
from the spraying area in a well ventilated area. Ventilation must be sufficient enough to
prevent the accumulation of vapors.
2. To eliminate electrostatic discharge, ground the spray unit, paint bucket and spraying object.
Use only high pressure airless hoses approved for 3000 psi which is conductive.
3. Remove spray tip before cleaning gun and hose. Make contact of gun with bucket and spray
without the tip in a well ventilated area, into the grounded steel bucket.
4. Never use high pressure in the cleaning process. USE MINIMUM PRESSURE.
5. Do not smoke in spraying/cleaning area.
GAS ENGINE PRECAUTIONS
Locate unit 25 feet away from spray area in well ventilated area.
• NEVER operate in closed buildings unless exhaust is piped outside.
• NEVER allow hose to lay against engine mufflers or hot parts.
• NEVER refill fuel tank while engine is hot or is running.
Important: United States Government safety standards have been adopted under the
Occupational Safety & Health Act. These standards, particularly the General Standards, Part
1910, & the Construction Standards, part 1926 should be consulted.
FLUSHING
