Warnings
The following Warnings are for safe setup, use, grounding, maintenance and repair of this equipment. The exclamation
point symbol alerts you to a general warning and the hazard symbols refer to procedure--specific risks. Refer back to
these Warnings.
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:
D Use equipment only in well ventilated area.
D 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.
D Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
D Keep work area free of debris, including solvent, rags and gasoline.
D Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are
present.
D Ground equipment and conductive objects in work area. See Grounding instructions.
D Use only grounded hoses.
D Hold gun firmly to side of grounded pail when triggering into pail.
D If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until
you identify and correct the problem.
D Keep a fire extinguisher in work area.
CARBON MONOXIDE HAZARD
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon monoxide
can cause death. Do not operate in an enclosed 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.
D Do not point gun at anyone or at any part of the body.
D Do not put your hand over the spray tip.
D Do not stop or deflect leaks with your hand, body, glove, or rag.
D Do not spray without tip guard and trigger guard installed.
D Engage trigger lock when not spraying.
D Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, check-
ing, or servicing equipment.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and
cause serious injury .
D Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, check-
ing, or servicing equipment.
D Tighten all fluid connections before operating the equipment.
D Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
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.
3110204
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
D Do not exceed the maximum working pressure or temperature rating of the lowest rated system compo-
nent. See Technical Data in all equipment manuals.
D 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.
D Check equipment daily. Repair or replace worn or damaged parts immediately.
D Do not alter or modify equipment.
D Use equipment only for its intended purpose. Call your Graco distributor for information.
D Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
D Do not kink or over bend hoses or use hoses to pull equipment
D Keep children and animals away from work area.
D Comply with all applicable safety regulations.
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns,
do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
D Keep clear of moving parts.
D Do not operate equipment with protective guards or covers removed.
D Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
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:
D Protective eyewear.
D Clothing and respirator as recommended by the fluid and solvent manufacturer.
D Gloves.
D Hearing protection.
RECOIL HAZARD
Brace yourself; gun may recoil when triggered and cause you to fall, which could cause serious injury.

Maintenance
Pressure Relief Procedure
1. Lock gun trigger safety.
2. Turn engine ON/OFF switch to OFF.
3. Move pump switch to OFF and turn pressure
control knob fully counterclockwise.
4. Unlock trigger safety. Hold metal part of gun firmly
to side of grounded metal pail, and trigger gun to
relieve pressure.
5. Lock gun trigger safety.
6. Open pressure drain valve. Leave valve open until
ready to spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, VERY SLOWLY
loosen tip guard retaining nut or hose end coupling to
relieve pressure gradually, then loosen completely.
Now clear tip or hose.
DAILY: Check and fill the gas tank.
AFTER THE FIRST 20 HOURS OF OPERATION:
Drain engine oil and refill with clean oil. Reference
Honda Engines Owner’s Manual for correct oil viscosity.
WEEKLY: Remove air filter cover and clean element.
Replace element, if necessary. If operating in an
unusually dusty environment: check filter daily and
replace, if necessary.
Replacement elements can be purchased from your
local HONDA dealer.
WEEKLY: Check level of TSL in displacement pump
packing nut. Fill nut, if necessary. Keep TSL in nut to
help prevent fluid buildup on piston rod and premature
wear of packings.
AFTER EACH 100 HOURS OF OPERATION:
Change engine oil. Reference Honda Engines Owner’s
Manual for correct oil viscosity.
SPARK PLUG: Use only BPR6ES (NGK) or
W20EPR--U (NIPPONDENSO) plug. Gap plug to
0.028 to 0.031 in. (0.7 to 0.8 mm). Use spark plug
wrench when installing and removing plug.
CAUTION
D Minimum hose size allowable for proper sprayer
operation is 3/8 in. x 50 ft
D For detailed engine maintenance and specifica-
tions, refer to separate Honda Engines Owner’s
Manual, supplied.
DAILY: Check engine oil level and fill as necessary.
DAILY: Check hose for wear and damage.
DAILY: Check gun safety for proper operation.
DAILY: Check pressure drain valve for proper opera-
tion.
Caster Wheel
(See letter call-outs in Parts drawing on page 28)
1. Once each year, tighten nut (127) under dust cap
(142) until spring washer bottoms out. Then back
off the nut 1/2 to 3/4 turn.
2. Once each year, tighten nut (127) on screw (131)
until it begins to compress spring washer. Then
tighten the nut an additional 1/4 turn.
3. Once each month, grease the wheel bearing (F).
4. Check pin (55) for wear. If pin is worn out, there
will be play in the caster wheel. Reverse or replace the pin as needed.
5. Check caster wheel alignment as necessary.
To align: loosen screw (145), align wheel and
tighten screw.
