Shipping Damage

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

Connect High--Pressure Hose and Gun

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

CAUTION

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

Install Spray Tip

Install the spray tip on the wand. (Installing and Changing Spray Tips, page 13). If you are using a Sandblast­ing Kit, see its separate manual for installation instructions.

Connect to Water Supply

Connect hose with at least a 3/4--in (19 mm) ID from the water supply to the 3/4--in garden hose inlet
on the pressure washer. The supply hose should not be more than 50 ft (15 m) long.

5309368

CAUTION

Before you connect the garden hose to the 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), a regulating water valve must be installed at the garden
hose connection.

Do not exceed 160_F(70_C) inlet water temperature.

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

6 309368

PRESSURE RELIEF

Follow these instructions whenever you are instructed to relieve pres­sure, stop spraying for more than 10 minutes, check or service the

equipment, or install or clean the spray nozzle.

1. Engage trigger safety latch.

2. Turn pressure washer off.

3. Remove ignition cable from spark plug.

4. Shut off water supply. Disconnect from water.

5. Disengage trigger safety latch and trigger the gun to
relieve pressure. Then re--engage the safety latch.

Note: If you suspect that the spray tip or hose is clogged or that pressure has not been fully relieved after
following the steps above, disengage the trigger safety latch and trigger the gun to relieve pressure.

7309368

Operation

Startup

Always use this startup procedure to ensure that the pressure washer is started safely and properly.

D Always engage the gun trigger safety latch when you stop spraying. This reduces the risk of fluid

injection or splashing in the eyes or on the skin if the gun is bumped or triggered accidentally.

D Always observe the CAUTIONS in this section to avoid costly damage to the pressure washer.

D If you use the Sandblaster Kit, see the Sandblaster Kit Manual for detailed cleaning information.

.

. Check the oil level of the engine and pump.

1

Oil level

NOTE: All Honda engine powered pressure washers are equipped with an engine low-oil sensor that shuts the
engine off if the oil level falls below a certain level. If the engine stops unexpectedly, check the oil and the fuel
levels. Check the oil level each time you add fuel.

WARNING

FIRE HAZARD

Do not refuel a hot engine. Refueling a hot engine could cause a fire. Use only fresh, clean,
regular or unleaded gasoline. Close the fuel shutoff valve during refueling.

2. Check fuel level.

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

NOTE: It is important to drain and refill the pump oil after the first 50 hours of operation.

8 309368

4

. Turn on water supply.

CAUTION

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

5

. Trigger the gun until a constant stream of water sprays from the tip indicating

the air is purged from the system.

6. Open fuel shutoff valve. Be sure the spark plug ignition

cable is pushed firmly onto the spark plug.

7. Put the switch in the ON position and the throttle at HALF

throttle.

9309368

CAUTION

Do not allow pressure washer to idle for more than 10 minutes. This causes the recirculating water to
overheat and serious damage to 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 helps keep abrasive sediment out of pump, which could clog pump or
damage cylinders. Keep screen clean. Do not pump caustic materials; such materials could corrode pump
components.

8. Pull the starter rope quickly to start the engine.

Pull and return the rope until the engine starts.
HINT: Placing one foot on the pressure washer
as a brace provides better leverage.

NOTE: For easier starting, have one person start pressure washer while another triggers gun.
D If engine is cold, start engine with choke completely closed. In cool weather, you might have to let engine

run with choke closed for first 10--30 seconds. In warm weather, open choke completely as soon as en­gine starts.

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

choke completely.

WARNING

Always engage the trigger safety latch when you stop spraying even for a moment. The
engaged, safety latch prevents the fun from being triggered accidentally by hand or when
dropped or bumped. Be sure the latch is pushed fully down, or it will not prevent the gun from
being triggered.

WARNING

11309368

Chemical Injector Operation

1

. Follow Pressure Relief Procedure (page 7).

2. Insert chemical filter (attached with clear tubing to

chemical injector) into the container of chemical.
Insert brass coupler into chemical injector.

3. Install the black, large--orifice, chemical tip. (Instal-

ling and Changing Spray Tips page 13).

The large orifice of the chemical tip causes a drop in
pressure that actuates the chemical injector. Changing
back to a small orifice spray tip deactivates the chemi­cal injector and produces high pressure for rinsing.
The chemical filter can be left in the chemical container
during high--pressure use. To regulate the flow rate of
the chemical, turn the chemical adjustment knob on the
injector.

12 309368

Installing and Changing Spray Tips

Spray tips have 4-- or 5--digit numbers on them.
The first two digits are the spray angle. Tip
holding holes are provided on the chassis.

NOTE: The chemical injector tip is brass and has a large opening and a black plastic cap.

. Perform Pressure Relief Procedure (page 7).

13309368

Shutdown, Flushing, and Storage

D Before you store the pressure washer

overnight or transport it, disconnect the water
supply, and turn off the fuel supply valve.

D After each use, wipe all surfaces of the

pressure washer with a clean, damp cloth.

14 309368

Long T erm (more than 30 days)/Winter Storage

S Do not store unit outside where it can be exposed to rain, dirt or adverse weather condi-

tions.

S Do not expose pressure washer to freezing temperatures or allow water to freeze in

pressure washer components, causing the pump to lock--up. If this happens let pump
thaw naturally in WARM ENVIRONMENT. DO NOT attempt to to speed up this process
by pouring warm water on pump. This could cause further damage.

ENGINE:

1. Run engine until gas is gone or stabilize the fuel and run it through the fuel system and carbu­retor.

2. Drain water out of pressure washer hose.

3. Turn fuel system to OFF position.

Pump:

1. Attach one end of a 4 or 5--foot section of hose to pump inlet and other end in an antifreeze
solution approximately 1--foot off the ground.

2. Pull pull--cord on engine until antifreeze comes out of pump outlet.
