IMPORTANT NOTES BEFORE APPLYING MATERIAL
1. Please note that many variables affect the adjustment of a spray gun including material viscos-
ity and type, atmospheric conditions such as humidity, barometric pressure, and temperature
as well as air inlet pressure and operator preference. Always "tune" the gun before each use as
prevailing conditions may not be the same as the previous use.
2. It is always best to test spray on sheets of cardboard or masking paper with the actual material
to be applied while making the required adjustments, to become familiar with the gun and
achieve the ideal Gun settings.
3. Remember that a small amount of product wasted at this point can avoid disappointment in the
finished results and the need to re-do work later.
4. DO NOT allow Gun to tilt up or down more than 45° while spraying or while not in use to avoid
fouling of the internal passages.
• Connect Gun to compressed air supply.
• Set regulator (not included) to an initial setting of 60 PSI [5 bar]. Test spray and adjust Gun as
described in SET-UP above and increase or decrease pressure as required.
This is a Pressure type of gun; higher viscosity materials will generally
require higher pressures than thinner materials however a "trial and error"
Set-up is required.
• Trigger operates similar to a HVLP paint gun.
1/2 pull trigger will allow air only to flow.
Full pull trigger will allow air and coating to flow.
• Always hang the Gun by the built-in hook between sprayings.
• When spraying is complete, follow Clean-Up procedure as described below.
