WARNING: High Pressure Fluid
Injection Hazard
High-pressure fluid discharge from leaks (even pin-
sized) or ruptured components can pierce skin and
inject fluid into the body. Injection injury can result in
blood poisoning and/or severe tissue damage leading
to infection, gangrene, and possibly amputation.
• Never use a finger or skin to check for leaks.
• Never operate machine with damaged or missing
hoses/parts.
• Never attempt to repair a high-pressure hose or
component – Always replace it with a part that is
rated at or above the pressure rating of this
machine.
Perform Scheduled Maintenance, As Needed
Make sure that any other regular maintenance has been
performed as prescribed in this manual in the
"Maintenance Schedule Summary" section.
Refer to the Engine Owner's Manual for engine
maintenance instructions.
Connect Hoses, Water Supply, and Spray
Nozzle
Position Pressure Washer for Use
For detailed instruction on positioning your pressure
•
washer for use, turn to the "Initial Set-Up" section of
this manual and reference "Step 3: Select Suitable
Location".
Where no flammable vapors, dusts, and gases are
•
present.
Where there is adequate, unobstructed ventilation
•
airflow.
With adequate clearance from combustible
•
materials.
On a firm, level, heat-resistant surface with good
•
drainage and nearby access to a continuous water
supply.
Attach Garden Hose to Water Inlet
1.) Make sure the water supply is clean. Debris can
cause excess pump wear and reduce performance.
2.) An insufficient water supply will damage your pump.
Make sure the water supply is steady and is 20%
over the rated flow of your pump. Use a stopwatch
to time how long it takes to fill a 5-gallon bucket with
your garden hose. The bucket must fill faster than
the times listed in the table below.

3.) The water supply garden hose must have an inside
diameter of at least 5/8". If the hose is more than
100 ft. long, the diameter must be at least 3/4".
4.) Never use a reservoir tank as a water source.
Drawing water out of a tank may cause pump
cavitation and damage to your pump. This pressure
washer is designed for a pressurized water source
such as a city water faucet. However, the water
source pressure must not exceed:

5.) Always use a flexible rubber hose for your water
supply. Do not use rigid piping.
Attach High Pressure Hose to Spray Gun
WARNING: High Pressure
NEVER operate this pump with components (such as
hose, connections, and spray gun) rated for lower
pressure and/or temperature limits than the machine's
maximum rated pressure and temperature, or
component could rupture and cause serious personal
injury from escaping high pressure fluids.
1. See "Component Identification" section of this
manual for location of the pressure washer's water
outlet.
2. Your pressure washer hose is equipped with quick
couplers. Simply pull the collar back and push the
coupler onto the water outlet nipple. The collar
should slide over the ball bearings.
3. Release the collar, making sure it springs back and
re-seats to its original (non-retracted) position.
Check the connection by pulling on the hose to
ensure a positive connection.
