Warnings

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.

• Keep a fire extinguisher in the work area.

Warnings

WARNING

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 end of the spray tip.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

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.

• 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.

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.

WARNING

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.

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

Setup

Shipping Damage

Check pressure washer for shipping damage. Notify the carrier immediately if there is any damage.

Connecting High-Pressure Hose and Gun

Connect high-pressure hose between pump outlet and gun inlet. Both of these connections are made with quick couplers.

ti5420a

Up to 100 ft (30 m) of 3/8 in. high-pressure hose may be used. Longer hoses could affect pressure washer and chemical injector performance balance.

Installing Spray Tip

Install spray tip on wand. (Installing and Changing Spray Tips, page.) If you are using a Sandblasting Kit, see its separate manual for installation instructions.

Connect to Water Supply

Connect hose from water supply to the garden hose inlet on the pressure washer.

• The supply hose should not be longer than 50 ft (15 m) in length.

• Inside diameter of hose should measure at least a 3/4 in. (19 mm).

ti5422a

CAUTION

• Before you connect garden hose to pressure washer, check your local plumbing code regarding cross-connection to the water supply. If required, install a backflow preventer.

• If the inlet water pressure is over 60 psi (4.1 bar, 41 MPa), a regulating water valve must be installed at the garden hose connection.

• Do not exceed 160° F (70° C) inlet water temperature.

The water source must have a minimum flow rate equal to that of the pressure washer.

Operation

Pressure Relief Procedure

Follow this procedure when you stop spraying and before cleaning, checking, servicing or transporting equipment.

1. Engage trigger lock.

TIA

4. Turn off water supply and disconnect pressure washer from water.

ti5425a

5. Unlock trigger lock. Trigger gun to relieve pressure. Engage trigger lock.

2. Turn pressure washer OFF.

OFF

ti5424a

3. Remove ignition cap from spark plug.

If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the pressure relief procedure, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction.

Operation

ti5431a

Startup

• Always engage the gun trigger safety latch when you stop spraying. This reduces the risk of fluid injection or splashing in eyes or on skin if the gun is bumped or triggered accidentally. Be sure latch is pushed fully down or it will not prevent the gun from being triggered.

ti5437a

engaged

• When using a sandblasting kit, refer the sandblaster kit instruction manual for detailed operating and cleaning information.

1. Check oil level of engine and pump.

disengaged

3. Check oil level in pump. It should be half way up the sight glass, located on the front of the pump. Add pump oil as necessary. The system is equipped with a thermal overload to help prevent severe damage.

Oil level

ti5430a

After the first 50 hours of operation, drain and refill pump oil.

4. Turn on water supply.

ti5428a

• All Honda engine-powered pressure washers are equipped with an engine low-oil sensor that shuts the engine off when the oil level falls below a certain level.

• If the engine stops unexpectedly, check the oil and fuel levels.

• Check the oil level each time you add fuel.

2. Check fuel level.

Fuel level

ti5429a

CAUTION

Always be sure the water supply is completely turned on before you run the pressure washer. Never run pressure washer without water. Costly pump damage will result.

5. Trigger gun until a constant stream of water sprays from the tip, indicating air is purged from the system.

6. Open fuel shutoff valve. Be sure spark plug ignition cable is pushed firmly on the spark plug.

Operation

7. Move switch to ON position and set throttle to HALF throttle position.

OFF

ti5434a

CAUTION

• Do not allow pressure washer to idle for more than 10 minutes. This causes the recirculating water to overheat and can seriously damage the pump.

• Turn off pressure washer if it will not be spraying at least every 10 minutes. If heated inlet water is used, reduce this time more.

• Do not operate pressure washer with inlet water screen removed. This screen help keep abrasive sediment out of pump. This sediment could clog pump or damage cylinders. Keep screen clean.

• Do not pump caustic materials which could corrode pump components.

• For easier starting, have one person start pressure washer while another triggers gun.

• If engine is cold, before starting engine, close choke completely. In cool weather you might have to run engine for the first 10-30 seconds with the choke closed. In warm weather, open choke completely as soon as engine starts.

• If engine is warm, start engine with choke completely open or only partially closed. When engine starts, open choke completely.

8. Trigger gun to produce a constant stream of water and, at the same time, pull starter rope quickly to start the engine. Pull and return rope until the engine starts. HINT: Placing one foot on the pressure washer as a brace provides better leverage.

ti5435a

1. Follow Pressure Relief Procedure (page 6).

2. Insert chemical filter (attached with clear tubing to chemical injector) into the chemical container. Insert brass coupler into chemical injector.
