WARNINGS
Fuel Hazard:
Fuel is combustible. When spilled on a hot surface it can ignite and cause a fire.
Do not fill fuel tank while engine is running or hot.
Exhaust Hazard:
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Do not operate this
equipment in a closed building.
Equipment Misuse Hazard:
Misuse of pressure washer or accessories can cause the equipment to rupture or malfunction and
result in serious injury.
DDo not alter or modify any part or factory--setting.
DCheck equipment daily. Repair or replace worn or damaged parts immediately.
DDo not exceed maximum working pressure (MWPR) of the lowest--rated system component.
DUse fluids and solvents that are compatible with the equipment wetted parts. See Specifications page
for this information.
DWear hearing protection when operating this equipment.
DDo not “blow back” fluid; this is not an air spray system.
DFollow Pressure Relief, page 7 before cleaning, checking or servicing equipment.
TOXIC FLUID HAZARD:
Hazardous fluid or toxi fumes can cause serious injury or death if splashed in eyes or on skin,
inhaled, or swallowed.
DKnow specific hazards of fluids you are using and take protective measures as recommended by
the fluid and solvent manufacturer.
Injection Hazard:
Spray from gun, leaks or ruptured components can inject fluid into your body and cause serious
injury. Fluid splashed in eyes or on skin can also cause serious injury.
DFluid injected into skin might look like just a cut, but it is a serious injury. Seek immediate surgical
treatment.
DDo not point gun at anyone or any part of the body.
DDo not stop or deflect leaks with hand, body, glove, or rag.
DDo not put your hand or fingers over the spray tip.
DTIghten fluid connections before you start this equipment.
DEngage the gun safety whenever you stop spraying.
DFollow Pressure Relief Procedure, page 7 if the spray tip clogs and before you clean, check or
service this equipment.
DRepair or replace worn or damaged parts immediately.
DCheck hoses, tubes, and couplings daily. Do not repair high--pressure couplings. Replace entire
hose. Fluid hoses must have spring guards on both ends to prevent kinks and rupture.

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.

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.

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.
