Page 4: Warnings
Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama- tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable. - Page 5 Warnings WARNING WARNING WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help pre- vent fire and explosion: • Use equipment only in well ventilated area. • Abrasive material exiting the blast nozzle can generate sparks. When flammable liquids are used near the blast nozzle or for flushing or cleaning, keep the blast nozzle at least 20 feet (6 meters) away from explosive vapors.

Page 12: Setting Up The Equipment
Operation Setting Up the Equipment 4. Connect blast hose, hose restraints, control hoses and coupler pins. 1. Shut the water tank drain valve (Q). Fill tank with water or connect to water supply. NOTICE Be sure the tank does not run dry during blasting, as this will damage the water pump. - Page 13 Operation 9. Open the pot dump valve (N). 13. Slowly increase pot pressure using pot pressure regulator (H) until water pump engages. Fill pot with water until the water level is above the pop up seal. 10. Add 10 gallons (30 liters) of fresh water to the pot. Add abrasive material: •...

Operation Wash Down 4. To resume blasting, turn selector valve (K) back to Blast and open the abrasive valve (P). 1. Close the abrasive valve (P). 5. To blow down substrate with air only, turn selector valve (K) to Off and close abrasive valve (P). 2. -
Page 18: Shutdown
Operation Shutdown 1. When you have finished blasting, perform wash until all of the abrasive is flushed from the blast hose. See “Wash Down” on page 17. 2. Turn the selector valve (K) to OFF, and with the abrasive valve (P) closed, continue to blast until water is cleared from the hose. -
