hose. Use the handle provided on the unit.  
• Always be certain the spray gun, nozzles and accessories  
are correctly attached.  
Do Not wear loose clothing, jewelry or anything that  
may be caught in the starter or other rotating parts.  
Do Not secure the spray gun in the (open) position.  
• High pressure spray may damage fragile items including  
glass. Do Not point spray gun at glass when in the jet  
spray mode.  
• Before starting the pressure washer in cold weather,  
check all parts of the equipment and be sure ice has not  
formed there.  
• Hold the spray gun firmly in your hand before you start  
the unit. Failure to do so could result in an injury from a  
whipping spray gun. Do Not leave the spray gun  
unattended while the machine is running.  
Never use a spray gun which does not have a trigger  
lock or trigger guard in place and in working order.  
• Keep the hose connected to machine or the spray gun  
while the system is pressurized. Disconnecting the hose  
while the unit is pressurized is dangerous.  
• The cleaning area should have adequate slopes and  
drainage to reduce the possibility of a fall due to slippery  
surfaces.  
Never operate units with broken or missing parts, or  
without protective housing or covers.  
• Keep water spray away from electric wiring or fatal  
electric shock may result.  
• Check the fuel system for leaks or signs of deterioration,  
such as chafed or spongy hose, loose or missing clamps,  
or damaged tank or cap. Correct all defects before  
operating the pressure washer.  
Do Not by–pass any safety device on this machine.  
• The muffler and engine heat up during operation and  
remain hot immediately after shutting it down. Avoid  
contact with a hot muffler or engine as you could be  
severely burned.  
Do Not spray flammable liquids.  
• Use a respirator or mask whenever there is a chance  
that vapors may be inhaled. Read all instructions with  
mask so you are certain the mask will provide the  
necessary protection against inhaling harmful vapors.  
• Operate and store this unit on a stable surface.  
• High pressure hose can develop leaks from wear, kinking,  
abuse, etc. Water spraying from a leak is capable of  
injecting material into skin. Inspect hose each time before  
using it. Check all hoses for cuts, leaks, abrasions or  
bulging of cover, or damage or movement of couplings. If  
any of these conditions exist, replace hose immediately.  
Never repair high pressure hose. Replace it with  
another hose that meets maximum pressure rating of  
your unit.  
Never aim the gun at people, animals or plants. The high  
pressure stream of water that this equipment produces  
can pierce skin and its underlying tissues, leading to  
serious injury and possible amputation.  
Never allow any part of the body to come in contact  
with the fluid stream. Do Not come in contact with a  
fluid stream created by a leak in the high pressure hose.  
• Always wear eye protection when you use this  
equipment or when you are in the vicinity where the  
equipment is in use.  
• The muffler and air cleaner must be installed and in good  
condition before operating the pressure washer. These  
components act as spark arresters if the engine backfires.  
• High pressure spray can cause paint chips or other  
particles to become airborne.  
In the State of California a spark arrestor is required by law  
(Section 4442 of the California Public Resources Code).  
Other states may have similar laws. Federal laws apply on  
federal lands.  
Do Not operate the pressure washer above the rated  
pressure.  
NOTE: If you equip the muffler with a spark arrestor, it  
must be maintained in effective working order. You can  
order a replacement spark arrestor through your  
authorized Honda service dealer.

• Apply a high pressure spray to a small area and then  
check the surface for damage. If no damage is found, you  
Pressure Washer Rinsing  
can assume it is okay to continue cleaning.  
WARNING! Be extremely careful if you must  
use the pressure washer from a ladder, scaffolding  
or any other relatively unstable location. Hose  
water pressure builds as you climb. When you press  
the trigger, the recoil from the initial spray can be  
very strong. The high pressure spray could force  
you to fall if you are too close to the cleaning  
surface.  
• Start at the top of the area to be rinsed, working down  
with same overlapping strokes as you used for cleaning.  
Automatic Cool Down System  
(Thermal Relief)  
If you run the engine on your pressure washer for  
3-5 minutes without pressing the trigger on the spray gun,  
circulating water in the pump can reach a temperature  
between 140–145°F. When the water reaches this  
temperature, the automatic cool down system engages and  
cools the pump by discharging the warm water onto  
the ground. This system prevents internal damage to the  
pump.  
After you have applied detergent, scour the surface  
and rinse it clean as follows:  
• Apply safety latch to spray gun.  
• Remove the black chemical nozzle from the nozzle  
extension.  
• Select and install the desired high pressure nozzle  
following the instructions “How to Use the Nozzles” on  
page 8.

GENERAL MAINTENANCE  
RECOMMENDATIONS  
The pressure washer warranty does not cover items that  
have been subjected to operator abuse or negligence. To  
receive full value from the warranty, the operator must  
maintain the high pressure washer as instructed in this  
manual.  
The high pressure hose can develop leaks from wear,  
kinking, or abuse. Inspect the hose each time before using  
it. Check for cuts, leaks, abrasions or bulging of cover,  
damage or movement of couplings. If any of these  
conditions exist, replace the hose immediately.  
WARNING! Water spraying from a leak is  
capable of injecting material into skin. Inspect hose  
each time before using it. Never repair a high  
pressure hose. Replace it with another hose that  
meets the maximum pressure rating of your  
pressure washer.  
• Some adjustments will need to be made periodically to  
properly maintain your high pressure washer.  
• All maintenance in this manual and the engine owner’s  
manual should be made at least once each season.  
• Once a year you should clean or replace the spark plug,  
clean or replace the air filter and check the gun and  
nozzle extension assembly for wear. A new spark plug  
and clean air filter assure proper fuel-air mixture and  
help your engine run better and last longer. Please refer  
to your engine owner’s manual for more details.  
Check Detergent Siphoning Tube  
Examine the filter on the detergent tube and clean if  
clogged. The tube should fit tightly on the barbed fitting.  
Examine the tube for leaks or tears. Replace the filter or  
tube if either is damaged.  
BEFORE EACH USE  
Cleaning Detergent Siphoning Tube  
If you used the detergent siphoning tube, you must flush it  
with clean water before stopping the engine.  
• Check engine oil level.  
• Check water inlet screen for damage.  
• Check in-line filter for damage.  
• Place the chemical injection siphon/filter in a bucket full  
of clean water.  
• Check high pressure hose for leaks.  
• Check detergent siphoning tube and filter for damage.  
• Check gun, nozzle extension, and nozzles for leaks.  
• Rinse out garden hose to flush out debris.  
• Attach the black low pressure nozzle.  
• Flush for 1-2 minutes.  
• Shut off the engine.  
IMPORTANT: Simply shutting OFF engine will not  
release pressure in the system. When the engine has  
shut down, squeeze the trigger on the gun to  
relieve the pressure in the hose.
