a risk of fire or explosion in the presence of paint or 

solvent fumes. All parts of the spray system, including 

the pump, hose assemble, spray gun, and objects in 

and around the spray area shall be properly grounded 

to protect against static discharge and sparks. Use 

only conductive or grounded high-pressure airless 

paint sprayer hoses specified by the manufacturer.

extension cords. Do not use a 3 to 2 adapter.

7) Do not use a paint or a solvent containing halogenated 

hydrocarbons. See operating instructions for examples 

of these types of materials.

of fresh air moving through the area. Keep pump 

assembly in a well ventilated area. Do not spray pump 

assembly.

producing products in the spray area.

sprayed. Read all Material safety Data Sheets (MSDS) 

and container labels provided with the paints and 

solvents. Follow the paint and solvent manufacturer’s 

safety instructions.

operational.

c) WARNING - To reduce the risk of skin injection.

nozzle tip to clean.

6) Do not leave the unit energized or under pressure while 

unattended. When the unit is not in use, turn off the 

unit and relieve the pressure in accordance with the

body and cause serious bodily injury. In the event that 

injection occurs, seek medical attention immediately.

8) Prior to use, thoroughly check the spray machine, hose 

and parts for any signs of visible damage. If there is 

any signs of damage or wear and tear, do not use the 

machine.
