Shipping Damage
Check the pressure washer for shipping damage. Notify the carrier immediately if there is any damage.
Setup
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.
Install Spray Tip
Install the spray tip on the wand. (Installing and Changing Spray Tips, page 13). If you are using a Sandblast-
ing Kit, see its separate manual for installation instructions.
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.
CAUTION
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.

6309368
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.

PRESSURE RELIEF
Follow these instructions whenever you are instructed to relieve pres-
sure, 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.

8309368
1.Check the oil level of the engine and pump.
Startup
Always use this startup procedure to ensure that the pressure washer is started safely and properly.
DAlways 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.
DAlways observe the CAUTIONS in this section to avoid costly damage to the pressure washer.
DIf you use the Sandblaster Kit, see the Sandblaster Kit Manual for detailed cleaning information.
.
Operation
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.
Oil level
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.
WARNING
2. Check fuel level. 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 over-
load 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.

4.Turn on water supply.
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.
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.
CAUTION

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.
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.
CAUTION
NOTE: For easier starting, have one person start pressure washer while another triggers gun.
DIf 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 en-
gine starts.
DIf engine is warm, start engine with choke completely open or partially closed. When engine starts open
choke completely.

1.Follow Pressure Relief Procedure (page 7).
Chemical Injector Operation
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 chemi-
cal 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.

13309368
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.
1.Perform Pressure Relief Procedure (page 7).
2.Point the gun and wand away from you and anyone else.
3.Without holding your hand over the spray tip (A), pull back the
quick coupler ring (B). Remove the current tip, install a differ-
ent one. Then push the ring back on.
