Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama­tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body 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.

• 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 all equipment in the 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.

• Keep a working fire extinguisher in the 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.

• 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.

313776G 3

Warnings

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• 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 forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu­facturer’s replacement parts only.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your 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.

• 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.

• 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.

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.

• Always wear impervious gloves when spraying or cleaning 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 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

Gun may recoil when triggered. If you are not standing securely, you could fall and be seriously injured.

General Repair Information

General Repair Information

SAE O-Ring Installation

1. Unscrew lock nut to touch
fitting.

1. Keep all screws, nuts, washers, gaskets, and
electrical fittings removed during repair proce­dures. These parts are not normally provided with
replacement assemblies.

2. Test repair after problem is corrected.

3. If sprayer does not operate properly, review
repair procedure to verify procedure was done cor­rectly. If necessary, see Troubleshooting, page 8,
for other possible solutions.

4. Install belt guard before operation of sprayer and
replace if damaged. Belt guard reduces risk of
pinching and loss of fingers.

Grounding

2. Lubricate o-ring (A).

Pressure Relief Procedure

1. Engage trigger lock.

2. Turn engine ON/OFF switch to OFF.

3. Move pump valve to OFF (clockwise) and turn pres­sure control knob fully counterclockwise.

4. Disengage the trigger lock. Hold a metal part of the
gun firmly to a grounded metal pail, and trigger the
gun to relieve pressure.

5. Engage the trigger lock.

6. Open pressure drain valve. Leave valve open until
you are ready to spray again.

If you suspect 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. Clear hose
or tip obstruction.

CAUTION

• Minimum hose size allowable for proper sprayer
operation is 3/8 in. x 50 ft.

• For detailed engine maintenance and specifica­tions, refer to separate Honda Engines Owner's
Manual, supplied.

DAILY: Check engine oil level and fill as necessary.

DAILY: Check hydraulic oil level and fill as necessary.

DAILY: Check hose for wear and damage.

DAILY: Check gun safety for proper operation.

DAILY: Top off TSL level in displacement pump packing

nut to help prevent material buildup on piston rod and
early wear of packings.

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 engine air filter cover and clean ele­ment and replace, if necessary. If operating in an unusu­ally dusty environment: check filter daily.

WEEKLY/DAILY: Remove any debris from hydraulic rod.

AFTER EACH 100 HOURS OF OPERATION: Change

engine oil. Reference Honda Engines Owner's Manual
for correct oil viscosity.

SEMI-ANNUALLY: Check belt wear, page 18; replace if
necessary.

YEARLY OR 2000 HOURS: Replace hydraulic oil and
filter element with Graco hydraulic oil 169236 (5 gal­lon/18.9 liter) or 207428 (1 gallon/3.8 liter) and filter ele­ment 246173; page 17.

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.

Caster Wheel

(See letter call-outs in Parts drawing on page 19.)

1. Once each year, tighten nut (127, detail A) until
spring washer bottoms out. Then back off the nut
1/2 to 3/4 turn.

2. Once each year, tighten nut (127) 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).

DAILY: Check prime/spray drain valve for proper opera­tion.

DAILY: Check and fill the gas tank.

DAILY: Check that displacement pump is tight.

313776G 7

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 bolt (145), align wheel and tighten bolt.
