Warnings
The following are general warnings are related to the setup, use, grounding, maintenance and repair of this equip-
ment. Additional more specific warnings may be found throughout the body of this manual where applicable. Symbols
appearing in the body of the manual refer to these general warnings. When these symbols appear throughout the
manual, refer back to these pages for a description of the specific hazard.
WARNING
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.
• Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is flammable
and can ignite or explode if spilled on hot surface.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground equipment and conductive objects in work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
• When flammable liquid is used in or near sprayer or for flushing or cleaning, keep sprayer at least 20
ft (6 m) away from explosive vapors.
• Keep a fire extinguisher in the work area.
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.

Specifications
311206A 3
Specifications
This equipment is not intended for use with flammable or combustible materials used in places
such as cabinet shops or other “factory” or fixed locations. If you intend to use this equipment in
this type of application, you must comply with NFPA 33 and OSHA requirements for the use of
flammable and combustible materials.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. 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. For complete information
about your material, request MSDS from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine ASM
replacement parts only.
• Do not alter or modify equipment.
• For professional use only.
• Use equipment only for its intended purpose. Call your ASM distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Comply with all applicable safety regulations.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids
containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical
reaction and equipment rupture, and result in death, serious injury, and property damage.
CARBON MONOXIDE HAZARD
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon mon-
oxide can cause death. Do not operate in an enclosed area.
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 equipment includes but is not limited to:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection

Installation
Grounding and Electric
Requirements
The sprayer must be grounded. Grounding reduces the
risk of static by providing an escape wire for the electri-
cal current due to static build up.
Ground sprayer with grounding clamp.
Spray gun:ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container:follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface such as concrete. Do not place the pail on a
nonconductive surface, such as paper or cardboard,
which interrupts grounding continuity.
Grounding the metal pail: connect a ground wire to the
pail by clamping one end to pail and other end to ground
such as a water pipe.
Maintaining grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.

HOT SURFACE HAZARD!
Engine and drive housing may be very hot during
operation and could burn skin if touched.

Tip Selection
6311206A
Tip Selection
Selecting Tip Hole Size
Tips come in a variety of hole sizes for spraying a range of fluids. Your Zip Spray sprayer includes the tip most likely
to satisfy common spraying applications. Use the tables below to determine the range of recommended tip hole sizes
for each fluid type. If you need a tip other than the one supplied, see the Super Uni - Tip Selection Chart below.
HINTS:
• As you spray, the tip wears and enlargens. Starting
with a tip hole size smaller than the maximum will
allow you to spray within the rated flow capacity of
the sprayer while using the tip you selected.
• Maximum tip hole size supported by the Zip Spray
sprayer is 0.017 in. (0.43 mm).
Super Uni - Tip Selection Chart
Using the Right Tip for the job
Consider the coating and the surface to be sprayed.
Make sure you use the best tip hole size for that coating
and the best fan width for that surface.
Tip Hole Size
Tip hole size controls the flow rate - the amount of paint
that comes out of the gun.
HINTS:
• Generally, use larger tip hole sizes with thicker coat-
ings and smaller tip hole sizes with thinner coatings.
• The maximum tip hole size a sprayer can support is
related to its maximum flow rate. the maximum tip
hole size supported by the Zip Spray sprayer is
0.017 in. (0.43 mm).
• Tips wear with use and need periodic replacement.
Fan Width
Fan width is the size of the spray pattern, which deter-
mines the area covered with each stroke. for a given tip
hole size, narrower fans deliver a thicker coat, and wider
fans deliver a thinner coat.
HINTS:
• Select a fan width best suited for the surface being
sprayed.
• Wider fans allow for faster coverage on broad, open
surfaces.
• Narrower fans allow for faster coverage on small,
confined surfaces.
