Toxic Substances
Spray Area
Certain material may be harmful if inhaled, or if there is contact with the skin.
Explosion Hazard – Incompatible Materials
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1,-Trichlo­roethane are not chemically compatible with the aluminum that might be used in many sys­tem components. The chemical reaction caused by these sol­vents reacting with aluminum can become violent and lead to
an equipment explosion.
Follow the requirements of the Material Safety Data Sheet supplied by coating material manu­facturer.
Adequate exhaust must be provided to keep the air free of accumulations of toxic materials.
Use a mask or respirator whenever there is a chance of inhaling sprayed materials. The mask must be compatible with the material being sprayed and its concentration. Equipment must be as prescribed by an industrial hygienist or
safety expert, and be NIOSH approved.
Aluminum is widely used in other spray appli­cation equipment - such as material pumps, regulators, triggering valves, etc. Halogenated hydrocarbon solvents must never be used with
aluminum equipment during spraying, ushing,
or cleaning. Read the label or data sheet for the material you intend to spray. If in doubt as to whether or not a coating or cleaning material is compatible, contact your coating supplier. Any other type of solvent may be used with aluminum equipment.

INTRODUCTION
RMA-202 Test Stand - Introduction
GENERAL INFORMATION
The Ransburg Applicator Performance Test Stand was developed to assist in determining
the applicator level of performance in an off-line condition. Insuring the applicator functions properly after any maintenance has been performed to it off-line reduces the costs associated with verifying performance during production. With line speeds critical to the through-put of a facility, every uptime
minute counts to underwrite protability. This Test
Stand device helps to insure the applicator per­forms correctly when it is put into service.
The Test Stand will verify performance of single or
dual uid applicators, bearing air, seal air, shaping
air, brake air and atomizing air. It also checks for kV and µA electrical performance of the applicator.
The Test Stand was developed with the user and the safety of the user in mind. The user must become familiar with the overall function and operation of the unit.
