SMake sure all equipment is rated and approved for the environment in
which you are using it.
SFollow all instructions for installing components and accessories.
SInstall all electrical, pneumatic, gas, and hydraulic connections to
local code.
SInstall locking, manual shutoff valves in the air supply lines to the
system. This allows you to relieve air pressure and lock out the
pneumatic system before undertaking maintenance and repairs.
SInstall a locking disconnect switch or breaker in the service line ahead
of any electrical equipment.
SUse only electrical wire of sufficient gauge and insulation to handle
the rated current demand. All wiring must meet all applicable codes.
SGround (and fuse, if necessary) all electrically conductive equipment
within 10 feet (3 meters) of the spray area or according to its rated
current consumption. (See the ID plate on your equipment.)
Ungrounded conductive equipment can store a static charge which
could ignite a fire or cause an explosion if a hot spark is discharged.
SRoute electrical wiring, cables, hoses, and air supply tubing along a
protected path. Make sure they will not be damaged. Do not bend
cables or hoses around a radius of less than 6 in. (152 mm).
SUse only designated lifting points or lugs to lift and move heavy
equipment. Always balance and block loads when lifting to prevent
shifting. Lifting devices must be inspected, certified, and rated for a
greater weight than the equipment being lifted.
SDo not use unapproved fluid hoses. Solvents may cause them to
deteriorate rapidly and allow flammable liquids or pressurized
material to escape.
SProtect components from damage, wear, and harsh environmental
conditions.
SAllow ample room for maintenance, material supply container drop-off
and loading, panel accessibility, and cover removal.
SProtect equipment with safety devices as specified by applicable
safety regulations.
SIf safety devices must be removed for installation, install them
immediately after the work is completed and check them for proper
functioning.

SNever touch exposed electrical connections or equipment while the
power is ON.
SIf you notice electrical arcing in a spray area, shut down the system
immediately. An arc can cause a fire or explosion.
SDo not operate the equipment at pressures higher than the rated
maximum working pressure of any component in the system.
SKeep parts of the body or loose clothing away from moving
equipment or parts. Remove jewelry and cover or tie back long hair.
SShut off moving equipment before taking measurements or inspecting
workpieces.
SWear National Institute of Occupational Safety and Health (NIOSH)
approved respirators while operating spray equipment and when
performing maintenance and cleaning tasks.
SWear gloves, eye protection, and protective clothing to protect your
skin when operating equipment.
SIf your skin has been exposed to dispense materials or solvents wash
frequently with soap and water, especially before eating or drinking.
Do not use solvents to remove coating materials from your skin.
SDo not use high-pressure compressed air to blow dust or powder off
your skin or clothes. High-pressure compressed air can be injected
under the skin and cause serious injury or death. Treat all
high-pressure fittings and hoses as if they could leak and cause
injury.
SNever point handguns or applicator nozzles at yourself or other
persons.
SDo not smoke in the spray area. A lit cigarette could ignite a fire or
cause an explosion.
SKeep paint pumps, pressure pots, and containers of flammable
materials far enough away from spray booths to prevent their
inclusion in a booth fire.
SMake sure the liquid in the heater is circulated to the external circuit
when the heater is operating.
