Warning
Warning
The following are general warnings related to the setup, use, maintenance and repair of this equipment. Additional,
more specific, warnings may be found throughout the text of this manual, where applicable.
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.
• When flammable liquid is sprayed or used for flushing or cleaning, keep sprayer at least 20 feet (6 m)
away from explosive vapors.
• 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.
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.
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.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• 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.

Warning
WARNING
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.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify equipment.
• Do not install a shut-off device between filter outlet and gun.
• Use equipment only for its intended purpose. Call your Graco distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not use hoses to pull equipment.
• Keep children and animals away from work area.
• 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.
SUCTION HAZARD
Never place hands near the pump fluid inlet when pump is operating or pressurized. Powerful suction
could cause serious injury.
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.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read MSDS’s to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
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.
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
RECOIL HAZARD
Brace yourself; gun may recoil when triggered and cause you to fall, which could cause serious injury.

What to do
Check engine oil level and fill as necessary.
Check hose for wear and damage.
Read Injection Hazard, page 3; Burn Hazard, page 4
1.
2.
3.
4.
5.
6.
Check that all hose fittings are secure.
Lock gun trigger safety.
Turn engine ON/OFF switch to OFF.
Move pump switch to OFF and turn pressure control knob
fully counterclockwise.
Unlock trigger safety. Hold metal part of gun firmly to side
of grounded metal pail, and trigger gun to relieve
pressure.
Lock gun trigger safety.
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.
Check gun safety for proper operation.
Check pressure drain valve for proper operation.
Check and fill the gas tank.
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 and pump corrosion.
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.
After each 50
hours of
operation
Replace pump. See pump manual 310894.
Weekly
Remove engine air filter cover and clean element.
Replace element, if necessary. If operating in an
unusually dusty environment: check filter daily and
replace, if necessary.
CAUTION
For detailed engine maintenance and specifications,
refer to separate Honda Engines Owner's Manual,
supplied.
Sendec Hour Meter
A Sendec Hour Meter has been installed on the rental
washer to monitor the number of hours the rental
washer has been used. After 25 hours the display will
begin to flash and the message “change oil” will display.
Reset meter using reset key or a magnet.
Replacement elements can be purchased from
your local HONDA dealer.
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.
Premium Sprayers Engine Oil Funnel:
Use the supplied engine oil funnel when draining oil.

be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy
(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or
consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these
warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or
