to PRIME to relieve the pressure. Refer to the 

Pressure Relief Procedure (page 7) 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.

• Paint hose can develop leaks from wear, kinking 

and abuse. A leak can inject material into the skin. 

Inspect the hose before each use. Do not use hose 

to lift or pull equipment.

• NEVER use a spray gun without a working trigger 

lock and trigger guard in place.

• All accessories must be rated at or above 2800 

PSI/193 BAR. This includes spray tips, guns, 

extensions, and hose.

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.

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.

• 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 eye wear.
• Wear protective clothing as required 

by coating manufacturer.

Solvent and paint fumes can explode or 

ignite.  Property damage and/or severe 

injury can occur.

• Provide extensive exhaust and fresh 

air introduction to keep the air within 

the spray area free from accumulation 

of flammable vapors. Solvent and 

paint fumes can explode or ignite.

• Do not spray in a confined area.
• Avoid all ignition sources such as static electric 

sparks, open flames, pilot lights, electrical 

appliances, and hot objects.  Connecting or 

disconnecting power cords or working light switches 

can make sparks.  Paint or solvent flowing through 

the equipment is able to result in static electricity.

• Do not smoke in spray area.
• Fire extinguisher must be present and in good 

working order.

• Place paint pump in a well-ventilated area away 

from the spray object. Flammable vapors are often 

heavier than air. Floor area must be extremely well 

ventilated.   

• The equipment and objects in and around the spray 

area must be properly grounded to prevent static 

sparks. 

• Keep area clean and free of paint or solvent 

containers, rags and other flammable materials.

• 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.  Know the contents of the 

paints 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 manufacturer’s safety instructions.

Indicates a hazardous situation which, 

if not avoided, could result in death or 

serious injury.

A high pressure paint 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 

amputation. See a physician immediately.
The maximum operating range of the gun is 2800 

PSI/193 BAR fluid pressure.

• NEVER aim the gun at any part of the body. 
• Do not aim the gun at, or spray any person or 

animal.

• 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 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 knob must be turned
