SafetySafety
Information
Read all safety information before operating
the equipment. Save these instructions
Indicates a hazardous situation which, if not
avoided, could result in death or serious injury.
a) To reduce the risks of re or explosion, electrical
shock and the injury to persons, read and
understand all instructions included in this manual.
Be familiar with the controls and proper usage of
the equipment.
Grounding Instructions
This product must be grounded. In the event of an electrical
short circuit, grounding reduces the risk of electric shock
by providing an escape wire for the electric current. This
product is equipped with a cord having a grounding wire with
an appropriate grounding plug. The plug must be plugged
into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
WARNING - Improper installation of the
grounding 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 grounding wire to either at blade
terminal. The wire with insulation having a green outer
surface with or without yellow stripes is the grounding wire
and must be connected to the grounding pin.
Check with a qualied electrician or serviceman if the
grounding instructions are not completely understood, or
if you are in doubt as to whether the product is properly
grounded. Do not modify the plug provided. If the plug
will not t the outlet, have the proper outlet installed by a
qualied electrician.
This product is for use on a nominal 120 volt circuit and
has a grounding plug that looks like the plug illustrated
below. Make sure that the product is connected to an
outlet having the same conguration as the plug. No
adapter should be used with this product.
b) WARNING - To reduce the risk of
re or explosion:
1. Do not spray ammable or
combustible materials near an open ame, pilot
lights or sources of ignition such as hot objects,
cigarettes, motors, electrical equipment and
electrical appliances. Avoid creating sparks from
connecting and disconnecting power cords.
2. Do not spray or clean with liquids having a ash
point of less than 21ºC (69.8ºF). Flash point is the
temperature at which a uid can produce enough
vapor to ignite.
3. Paint or solvent owing through the equipment is
able to result in static electricity. Static electricity
creates a risk of re or explosion in the presence
of paint or solvent fumes. All parts of the spray
system, including the pump, hose assembly, spray
gun and objects in and around the spray area
shall be properly grounded to protect against static
discharge and sparks. Use only conductive or
grounded high-pressure airless paint sprayer hoses
specied by the manufacturer.
4. Verify that all containers and collection systems are
grounded to prevent static discharge.
5. Connect to a grounded outlet and use grounded
extension cords (electric models only). Do not use
a 3 to 2 adapter.
6. Do not use a paint or solvent containing
halogenated hydrocarbons. Such as chlorine,
bleach mildewcide, methylene chloride and
trichloroethane. They are not compatible with
aluminum. Contact the coating supplier about
compatibility of material with aluminum.
7. Keep spray area well ventilated. Keep a good
supply of fresh air moving through the area to keep
the air within the spray area free from accumulation
of ammable vapors. Keep pump assembly in well
ventilated area. Do not spray pump assembly.
8. Do not smoke in the spray area.
9. Do not operate light switches, engines, or similar
spark producing products in the spray area.
10. Keep area clean and free of paint or solvent
containers, rags, and other ammable materials.
11. Know the contents of the paint and solvents being
sprayed. Read all Material Safety Data Sheets
(MSDS) and container labels provided with the
paints and solvents. Follow the paint and solvent
manufacture’s safety instructions.
12. Place pump at least 25 feet (7.62 meters) from the
spray object in a well ventilated area (add more
hose if necessary). Flammable vapors are often
heavier than air. Floor area must be extremely well
ventilated. The pump contains arcing parts that
emit sparks and can ignite vapors.
13. Plastic can cause static sparks. Never hang plastic
to enclose spray area. Do not use plastic drop
cloths when spraying ammable material.
14. Fire extinguisher equipment shall be present and
working.
c) WARNING - To reduce the risk of skin
injection:
1. Do not aim the gun at, or spray any person
or animal.
2. Keep hands and other body parts away from the
discharge. For example, do not try to stop leaks
with any part of the body.
3. Always use the nozzle tip guard. Do not spray
without the nozzle tip guard in place.
4. Only use a nozzle tip specied by the
manufacturer.
5. Use caution when cleaning and changing nozzle
tips. In the case where the nozzle tip clogs while
spraying, ALWAYS lock gun trigger, shut pump
off, and release all pressure before servicing,
cleaning tip or guard, or changing tip. Pressure
will not be released by turning off the motor. The
PRIME/SPRAY valve or pressure bleed valve must
be turned to their appropriate positions to relieve
system pressure. Refer to PRESSURE RELIEF
PROCEDURE described in the pump manual.
6. Do not leave the unit energized or under pressure
while unattended. When the unit is not in use, turn
off the unit and relieve the pressure in accordance
with the manufacturer’s instructions.
7. 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.

8. Check hoses and parts for signs of damage, a leak can
inject material into the skin. Inspect hose before each
use. Replace any damaged hoses or parts.
9. This system is capable of producing 2800 PSI / 193
Bar. Only use replacement parts or accessories that
are specied by the manufacturer and that are rated a
minimum of 2800 PSI. This includes spray tips, nozzle
guards, guns, extensions, ttings, and hose.
10. Always engage the trigger lock when not spraying.
Verify the trigger lock is functioning properly.
11. Verify that all connections are secure before operating
the unit.
12. Know how to stop the unit and bleed pressure quickly.
Be thoroughly familiar with the controls. Pressure will
not be released by turning off the motor. The PRIME/
SPRAY valve or pressure bleed valve must be turned to
their appropriate positions to relieve system pressure.
Refer to PRESSURE RELIEF PROCEDURE described
in the pump manual.
13. Always remove the spray tip before ushing or cleaning
the system.
10. Follow all appropriate local, state and national
codes governing ventilation, re prevention and
operation.
11. The United States Government Safety Standards
have been adopted under the Occupational
Safety and Health Act (OSHA). These standards,
particularly part 1910 of the General Standards and
part 1926 of the Construction Standards should be
consulted.
12. Before each use, check all hoses for cuts, leaks,
abrasion or bulging of cover. Check for damage or
movement of couplings. Immediately replace hose
if any of those conditions exist. Never repair a paint
hose. Replace with a conductive high-pressure
hose.
13. Do not spray outdoors on windy days.
14. Always unplug cord from outlet before working on
equipment (electric models only).
Important Electrical Information
IMPORTANT: Use only a 3-wire extension cord that
has a 3-blade grounding plug and a 3-slot receptacle
that will accept the plug on the product. Make sure
your extension cord is in good condition. When
using an extension cord, be sure to use one heavy
enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. A 14
or 12 gauge cord is recommended (see chart). If
an extension cord is to be used outdoors, it must
be marked with the suffix W-A after the cord type
designation. For example, a designation of SJTW-A
would indicate that the cord would be appropriate
for outdoor use.
Cord gauge Maximum cord length
12 150 feet
14 100 feet
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.
d) WARNING - To reduce the risk of injury:
1. Always wear appropriate gloves, eye protection,
clothing and a respirator or mask when painting.
Hazardous vapors – Paints, solvents, insecticides, and
other materials can be harmful if inhaled or come in
contact with body. Vapors can cause severe nausea,
fainting or poisoning.
2. Do not operate or spray near children. Keep children
away from equipment at all times.
