SAFETY PRECAUTIONS
HAZARD: Injection injury - A high pressure stream produced
by this equipment can pierce the skin and underlying
tissues, leading to serious injury and possible
amputation. See a physician immediately.
DO NOT TREAT AN INJECTION INJURY AS A SIMPLE CUT!
Injection can lead to amputation. See a physician immediately.
The maximum operating range of the gun is 3600 PSI / 25 MPa
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 hand in front of the gun. Gloves will not provide
protection against an injection injury.
• ALWAYS lock the gun trigger, shut the pump off, and release all
pressure before servicing, cleaning the tip or guard, changing tip, or
leaving unattended. Pressure will not be released by turning off the
motor. The PRIME/SPRAY valve must be turned to PRIME to
relieve the pressure. Refer to the PRESSURE RELIEF PRESSURE
described in the pump manual.
• ALWAYS keep the 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 trigger lock and trigger guard
in place and in good working order.
• All accessories must be rated at or above 3600 PSI / 25 MPa.
This includes spray tips, guns, extensions, and hose.
HAZARD: EXPLOSION OR FIRE - Solvent and paint fumes can
explode or ignite. Severe injury and/or property
damage can occur.
PREVENTION:
• Provide extensive exhaust and fresh air introduction to keep the
air within the spray area free from accumulation of flammable
vapors.
• Avoid all ignition sources such as static electricity sparks,
electrical appliances, flames, pilot lights, hot objects, and sparks
from connecting and disconnecting power cords or working light
switches.
• Do not smoke in spray area.
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.
• Fire extinguisher must be present and in good working order.
• Place pump at least 20 feet (6.1 m) 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.
• The equipment and objects in and around the spray area must
be properly grounded to prevent static sparks.
• Use only conductive or grounded high pressure fluid hose. Gun
must be grounded through hose connections.
• Power cord must be connected to a grounded circuit.
• Always flush unit into a separate metal container, at low pump
pressure, with spray tip removed. Hold gun firmly against side of
container to ground container and prevent static sparks.
• Follow the material and solvent manufacturer's warnings and
instructions.
• Use extreme caution when using materials with a flashpoint
below 70° F (21° C). Flashpoint is the temperature that a fluid
can produce enough vapors to ignite.
• Plastic can cause static sparks. Never hang plastic to enclose a
spray area. Do not use plastic drop cloths when spraying
flammable materials.
• Use lowest possible pressure to flush equipment.
HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE
MATERIALS - will cause severe injury or property
damage.
PREVENTION:
• Do not use materials containing bleach or chlorine.
• Do not use halogenated hydrocarbon solvents such as bleach,
mildewcide, methylene chloride and 1,1,1 - trichloroethane.
They are not compatible with aluminum.
• Contact your coating supplier about the compatibility of material
with aluminum.
HAZARD: HAZARDOUS VAPORS - Paints, solvents,
insecticides, and other materials can be harmful if
inhaled or come in contact with the body. Vapors can
cause severe nausea, fainting, or poisoning.
PREVENTION:
• Use a respirator or mask if vapors can be inhaled. Read all
instructions supplied with the mask to be sure it will provide the
necessary protection.
• Wear protective eyewear.
• Wear protective clothing as required by coating manufacturer.
HAZARD: GENERAL - Can cause severe injury or property
damage.
PREVENTION:
• Read all instructions and safety precautions before operating
equipment.
• Always disconnect the motor from the power supply before
working on the equipment.
• Follow all appropriate local, state, and national codes governing
ventilation, fire prevention, and operation.
• 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.
• Use only manufacturer authorized parts. User assumes all risks
and liabilities when using parts that do not meet the minimum
specifications and safety devices of the pump manufacturer.
• Before each use, check all hoses for cuts, leaks, abrasion or
bulging of cover. Check for damage or movement of couplings.
Immediately replace the hose if any of these conditions exist.
Never repair a paint hose. Replace it with another grounded
high-pressure hose.
• All hoses, swivels, guns, and accessories must be pressure
rated at or above 3600PSI / 25 MPa.
• Do not spray outdoors on windy days.
• Wear clothing to keep paint of skin and hair.

WARNING

OPERATING INSTRUCTIONS
LOCKING AND UNLOCKING THE GUN
Always lock the gun off when it is
not in use. To lock the gun, turn
the trigger lock forward and slightly
down until it stops. To unlock the
gun, turn the trigger lock so that it
is vertical and pointing up.
POSSIBLE INJECTION HAZARD.
Do not spray without the tip guard in place. Never trigger the gun
unless the tip is in either the spray or the unclog position. Always lock
the gun off before removing, replacing or cleaning the tip.
A
TTACHING THE TIP
1. Thread the spray tip onto the gun. Tighten
the nut first by hand, then tighten more firmly
with a wrench.
A
TTACHING THE FILTER
1. Insert the tapered plastic end of the paint filter into the fitting on the spray gun.
2. Place the spring into the filter housing.
3. Place the white sealing washer into the filter housing with
the lipped side up.
4. Slide the filter housing over the filter and screw the filter
housing securely to the fitting.
UNCLOGGING THE SPRAY TIP
Do not attempt to unclog or clean the tip with your finger. Do not use a
needle or other sharp pointed instrument to clean the tip. The hard
tungsten carbide is brittle and can be chipped.
The spray gun is equipped with a reversible tip which allows you to blow
out any particles of old paint or other contaminants that may obstruct the
paint flow through the tip. If the spray pattern becomes distorted or
stops completely while the gun is triggered, follow these steps:
1. Release the trigger and lock the gun off.
2. Rotate the reversible tip cylinder arrow 180° so that
the point of the arrow is toward the rear of the gun.
3. Unlock the gun and squeeze the trigger, pointing
the gun at a scrap piece of wood or cardboard.
This allows pressure in the spray hose to blow out
the obstruction. When the nozzle is clean, paint will
come out in a straight, high pressure stream.
4. Release the trigger and lock the gun off.
5. Reverse the tip so the arrow points forward again.
6. Unlock the gun and resume spraying.
If spraying with latex paint, use warm soapy water for cleaning. If using
oil or alkyd-based paints, use mineral spirits or paint thinner. Refer to
the paint manufacturer’s instructions for specific recomendations.
Do not use mineral spirits or paint thinner on latex paint, or the mixture
will turn into a jellylike substance which is difficult to remove.
CLEANING THE SPRAY GUN FILTER
The spray gun includes a filter to catch particles before they reach the spray
tip. If this filter becomes clogged or obstructed it will reduce the flow of paint,
changing the spray pattern and possibly damaging the filter.
This filter must be cleaned daily. If the material being used is old or contains
hardened particles, then the filter should be cleaned approximately every 4
hours. If the filter is not cleaned at the proper time, it will plug and blow pin
holes in the filter. Holes in the filter will allow unwanted particles to get into
the spray tip, causing the spray tip to clog.
Clean the filter by rinsing it thoroughly in water or the type of solvent appropriate to the paint you are using. If this is not sufficient, use a natural or nylon
bristle brush dipped in water or the appropriate solvent. Do not use a wire
brush or any sharp instrument on the filter.
CLEANING THE GUN
1. Check that the spray tip assembly has been removed from the gun.
2. Remove the filter and reattach the filter housing to the gun.
3. Run the appropriate solvent through the pump.
4. Hold the metal part of the gun against a metal
container to ground the gun.
5. Trigger the gun into the container until it is flushed
clean. Use the lowest possible pressure.
REPLACING THE VALVE SPRING UNIT
1. Unscrew the spray tip.
2. Lock the gun in the ON position
and remove the diffuser with a
wrench.
3. Unlock the gun.
4. Unscrew the nut with a wrench and
remove the retainer block.
5. Remove the sliding pins with care
and store them in a safe place so
they will not be lost.
6. Drive the valve spring unit forward
from the back of the retainer block. Use the handle of a wooden hammer or similar soft tool to avoid damaging the valve spring unit.
