Airless Paint Sprayers

SkIN INjECTION hAzArD:

  High pressure spray can inject toxins 

into blood stream. If injection 
occurs, seek emergency medical 
treatment.

 

  

use a face mask/respirator 
and protective clothing 
when spraying. Always 
spray in a well ventilated area to 
prevent health and fire hazards. Refer 
to Material Safety Data Sheets (MSDS) 
of spray material for details.

  Never try to stop leaks with any 

part of your body.

  This system is capable of producing 

2800 psi (19 300 kPa). Use only 
Campbell Hausfeld replacement 
parts rated at 2800 psi (19 300 kPa) 
or higher.

 

To reduce the risk of 
skin injection:

  Do not aim the 

gun at, or spray, 
any person or 
animal.

  Keep hands and other body parts 

away from the discharge. For 
example, do not try to stop leaks 
with any part of the body.

  Do not clean spray tip while it is 

attached to the spray gun. Remove 
spray tip from gun to clean tip 
guard.

  Always use the nozzle tip guard. Do 

not spray without nozzle tip guard

removing the nozzle tip, follow 
the manufacturer’s instructions for 
turning off the unit and relieving 
the pressure.

  Do not leave the unit energized or 

under pressure while unattended. 
When not in use turn off the 
unit and relieve the pressure in 
accordance with the manufacturer’s 
instructions.

  High pressure spray is able to inject 

toxins into the body and cause 
serious bodily injury. In the event 
that injection occurs, seek medical 
attention immediately.

  Check parts for signs of damage. 

Replace any damaged parts.
