paint sprayers. Additional warnings are found throughout this manual where applicable. Symbols appearing in the
manual refer to these warnings. Refer back to these pages for the symbol’s description of the specific hazard.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths
which may present a potential static arc.
• Sprayer generates sparks. When flammable liquid is used in or near the sprayer or for flushing or cleaning,
keep sprayer at least 20 feet (6 m) away from explosive vapors.
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Ground equipment and conductive objects in work area. Refer to the Grounding instructions.
• If there is static sparking or you feel a shock, stop use immediately. Do not use equipment until you identify
and correct the problem.
• Keep a fire extinguisher in the work area.
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off unit and unplug power cord before servicing equipment.
• Use only 3-wire extension cords and plug into only grounded electrical outlets.
• Ensure ground prongs are intact on sprayer’s power cord and extension cords.
• CAUTION:To reduce the risk of electrical shock, do not expose to rain. Store indoors.
SKIN INJECTION HAZARD
High-pressure fluid from tip, gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut,
but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip. Use only spray tip specified by TriTech.
• Do not stop or deflect leaks with your hand or body, glove, or rag.
• Engage trigger lock when not spraying.
•Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking or
servicing equipment.

PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This protective equipment includes but is not limited to;
• Protective eye wear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
• Gloves
• Hearing protection
GROUNDING:
The sprayer must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire
for the electrical current due to static build up or in the event of a short circuit.
• The sprayer power cord includes a grounding wire with an appropriate grounding contact.
• The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
• Do not modify plug. If it will not fit in outlet have grounded outlet installed by a qualified electrician. Do not
use an adapter.
Use only the correct pressure rated airless hose with static ground to reduce the risk of static discharge or injection.
POWER REQUIREMENTS
• 110V units required 100-120VAC 50/60Hz. 12A, 1 phase
• 220V units require 220-240 VAC, 50/60Hz, 6A, 1 phase
EXTENSION CORDS
• Use an extension cord with ground contact only. Should an extension cord be necessary use a 3 wire, 12 AWG
(2.5mm2) minimum. Do not exceed 300 ft 100 meters
PAILS
• Solvent and oil based fluids: follow local code. Use only conductive metal pails, place on a grounded surface
such as concrete.
• Do not place pail on a nonconductive surface such as paper or cardboard which interrupt grounding continuity.
• To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun with the
airless tip removed firmly to side of the grounded metal pail. Then trigger gun.
