The maximum operating range of the unit is 20.7 MPa
(3000 PSI) fluid pressure.
PREVENTION:
• NEVER aim the gun at any part of the body.
• NEVER allow any part of the body to touch the fluid stream.
DO NOT allow body to touch a leak in the fluid hose.
• NEVER put your hand in front of the gun. Gloves will not
provide protection against an injection injury.
• ALWAYS lock the gun trigger, shut the fluid pump off and
release all pressure before servicing, cleaning the tip
guard, changing tips, or leaving unattended. Pressure will
not be released by turning off the engine. The
PRIME/SPRAY valve or pressure bleed valve must be
turned to their appropriate positions to relieve system
pressure. Refer to the PRESSURE RELIEF
PROCEDURE described in this manual.
• ALWAYS keep tip guard in place while spraying. The tip
guard provides some protection but is mainly a warning
device.
• ALWAYS remove the spray tip before flushing or cleaning
the system.
• The paint hose can develop leaks from wear, kinking and
abuse. A leak can inject material into the skin. Inspect
the hose before each use.
• NEVER use a spray gun without a working trigger lock
and trigger guard in place.
• All accessories must be rated at or above the maximum
operating pressure range of the sprayer. This includes
spray tips, guns, extensions, and hose.
NOTE TO PHYSICIAN:
Injection into the skin is a traumatic injury. It is
important to treat the injury as soon as possible. DO
NOT delay treatment to research toxicity. Toxicity is a
concern with some coatings injected directly into the
blood stream. Consultation with a plastic surgeon or
reconstructive hand surgeon may be advisable.

Earthing Instructions
Electric models must be earthed. In the event of an electrical
short circuit, earthing reduces the risk of electric shock by
providing an escape wire for the electric current. This product
is equipped with a cord having an earthing wire with an
appropriate earthing plug. The plug must be plugged into an
outlet that is properly installed and earthed in accordance with
all local codes and ordinances.
DANGER — Improper installation of the earthing plug can
result in a risk of electric shock. If repair or replacement
of the cord or plug is necessary, do not connect the green
earthing wire to either flat blade terminal. The wire with
insulation having a green outer surface with or without
yellow stripes is the earthing wire and must be connected
to the earthing pin.
Check with a qualified electrician or serviceman if the earthing
instructions are not completely understood, or if you are in
doubt as to whether the product is properly earthed. Do not
modify the plug provided. If the plug will not fit the outlet, have
the proper outlet installed by a qualified electrician.

the gun unless the tip is completely
turned to either the spray or the unclog
position. ALWAYS engage the gun
trigger lock before removing, replacing or cleaning tip.
he key to a good paint job is an even coating over the entire
T
surface. This is done by using even strokes. Keep your arm
moving at a constant speed and keep the spray gun at a
constant distance from the surface. The best spraying distance
is 10 to 12 inches between the spray tip and the surface.
Keep the spray gun at right angles to the surface. This means
moving your entire arm back and forth rather than just flexing
your wrist.
Overlap each stroke by about 30%. This will ensure an even
coating.
When you stop painting, lock the gun trigger lock, turn the
pressure control knob counterclockwise to its lowest setting
and set the PRIME/SPRAY valve to PRIME. Move the motor
ON/OFF switch to OFF and unplug the sprayer.
If you expect to be gone more than 1 hour, follow the short
term clean up procedure described in the CLEANUP section of
this manual.
Practice
1. Be sure that the paint hose is free of kinks and clear of
objects with sharp cutting edges.
2. Turn the pressure control knob counterclockwise to its to
its lowest setting.
Keep the spray gun perpendicular to the surface, otherwise
one end of the pattern will be thicker than the other.
The spray gun should be triggered by turning it on and of
each stroke. This will save material and avoid material buildup
at the end of the stroke. Do not trigger the gun during the
middle of a stroke. This will result in an uneven spray and
splotchy coverage.
3. Turn the PRIME/SPRAY valve to SPRAY.
4. Turn the pressure control knob clockwise to its highest
