• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
Equipment Misuse Hazard
Equipment misuse can cause death or serious injury.
• Do not exceed maximum working pressure or temperature rating of lowest rated system compo-
nent. See Technical Data, in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings.
• Check equipment daily. Repair or replace worn or damaged parts immediately.

WARNINGS
SKIN INJECTION HAZARD
High-pressure fluid from 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.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
Cleaning Solvent Hazard with Plastic Parts
Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many
solvents can degrade plastic parts to the point where they could fail. Such failure could cause serious
injury or property damage. See Technical Data on page 34 of this instruction manual and in all other
equipment manuals. Read fluid and solvent manufacturer’s warnings.
Moving Parts Hazard
Moving parts can pinch or amputate fingers and other body parts.
• Keep clear of moving parts.

(K) all the way down to
reduce pressure.
3 Open gun air valve (aa).
4 Trigger gun, spraying

Grounding and Electric Requirements
The sprayer must be grounded. Grounding reduces the
risk of electrical shock by providing an escape wire for
the electrical current.
• The sprayer cord includes a
grounding wire with an appro-
priate grounding prong.
• 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 out-
let installed by a qualified elec-
trician.
• Sprayer model electric require-
ments are provided on page 2.
Extension Cords
• Only use an extension cord with
an undamaged 3-prong plug.
• For up to 100 ft (30.48 m) cord,
use 3-wire, 12 AWG (2.5 mm2)
minimum.

atomization air is necessary.
Generators
7500 W (7.5 KW) minimum.
Tips for Using Generators
• Before running sprayer, make sure it is at room tem-
perature. This will reduce startup current.
• Run generator at full throttle.
Hose Lengths
• The system comes with a twin line hose set consist-
ing of a 1 in. ID x 25 ft (25 mm x 7.6 m) material hose
and a 3/8 in. ID air hose. Additional hose sections can
be added. Total final length of hose used should not
exceed 100 feet in length.
CAUTION
Attaching auxiliary air to sprayer without using the
Auxiliary Air Hookup Kit will damage sprayer. CAUTION
Sprayer air hose fitting can get hot! Allow sprayer to
cool down 5 minutes before removing air hose.
