Frequently Asked Questions
How do I start my pressure washer?
1. Make sure you have gas and oil in the engine.
2. Turn the water on, then trigger the gun to make sure the water will flow smoothly out of the nozzle or tip.
3. Put the engine throttle control in the “Fast/Start” position. Set the fuel shut off switch to “ON.” Set the on/off switch to “ON” (if
applicable).
4. Set the choke to “ON.”
5. Pull the trigger (to relieve any back pressure in the pump) while pulling the starter cord.
6. If the engine does not start after three tries, repeat Step 5 (See Page 6) or see Troubleshooting Section (Pages 12-13).
What type of oil do I use?
The pump on the horizontal pressure washer comes filled with the correct amount of oil and should not need filling. See Page 11 for
pump oil types and quantities. THE ENGINE DOES NOT COME FILLED WITH OIL. See Page 11 for engine oil types and quantities. Refer
to Pages 10 and 11 of this manual and also refer to the included engine owner’s manual for oil changing instructions.
Why don’t I have any water pressure?
• Is the water hose attached to the pressure washer?
• Is the water turned on?
• Check for any kinks, leaks, or blockage in the hoses, fittings, or the nozzle.
• Is the adjustable nozzle in the low psi position? If so, move it into the high psi position (See Page 8).
• Is the inlet filter screen free of debris? Check and remove debris if needed.
• Is the quick connect tip in place? (See Page 4.)
How do I get high pressure?
• For high pressure, move the nozzle into the high psi position (See Page 8).
• For units with quick connect tips: use any color tip with the exception of black. Black tip is used for low pressure detergent application.
How do I get the soap suction to work?
1. Attach clear plastic tube to brass barb on pump (See Page 4).
2. Insert filter end of clear plastic tube into detergent liquid.
3. Move the nozzle into the low psi position (See Page 8).
4. For quick connect lance, use black detergent tip (see Page 8).
Why doesn’t the pressure washer apply detergents with high pressure?
The reason you don’t apply detergents with high pressure is that the detergents “bounce” off the cleaning surface as fast as you
apply them. Detergent is only effective when you allow it time to work on the surface of whatever you are cleaning. You can only
apply detergent at low pressure, wait 1-3 minutes to allow it to work, and rinse the surface with high pressure.
What maintenance do I need to perform on my pressure washer?
1. After turning off the pressure washer and the water, depressurize the hose by triggering the gun.
2. Remove the garden hose and high pressure hose from the pump.
3. Pull the start rope slowly five times to purge water from the pump. This will help protect the pump from damage.
4. Do not store your pressure washer in an area where the temperature will drop below 32˚ F unless pressure washer is properly winterized (see Page 9).

be used only by trained operators.
Always remove lance from gun before
cleaning debris from tip.
• Keep clear of nozzle. NEVER direct
high pressure spray at a person, animal, or yourself.
• Always wear safety glasses or gog-
gles and protective equipment
(hearing protection, gloves, rubber

a few moments.
• Always follow detergent manufac-
turer’s label recommendations for
proper use of detergents. Always
protect eyes, skin, and respiratory
system from detergent use.
Do not use pres-
sure that exceeds
the operating pressure of any of the
parts (hoses, fittings, etc.) in the pressurized system. Ensure all equipment
and accessories are rated to withstand
the maximum working pressure of the
unit.
Explosion
hazard.
• NEVER spray flammable liquids or
use pressure washer in areas containing combustible dust, liquids, or
vapors.
• NEVER operate this machine in a
closed building or in or near an
explosive environment.
• Do not remove fuel tank cap or fill
fuel tank while engine is hot or running (allow engine to cool two minutes before refueling). Always fill
the tank slowly.
• Never disconnect the high pressure
discharge hose from the machine
while the system is pressurized. To
depressurize machine, turn power
and water supply off, then press
the gun trigger 2-3 times.
• Never permanently engage the trigger mechanism on the gun.
• Never operate the machine without
all components properly connected
to the machine (handle, gun/wand
assembly, nozzle, etc.).
Equipment
damage.
•ALWAYS turn water supply “ON”
before turning pressure washer
“ON.” Running pump dry causes
serious damage.
• Do not operate the pressure washer
with the inlet water screen
removed. Keep screen clear of
debris and sediment.
• NEVER operate pressure washer
with broken or missing parts. Check
equipment regularly and repair or
replace worn or damaged parts
immediately.
• Use only the nozzle supplied with
this machine.
• Never leave the wand unattended
while the machine is running.
• Never tamper with the engine governor or attempt to alter factory
settings. Altering factory settings
could damage the unit and will
void the warranty.
• Always hold gun and wand firmly
when starting and operating the
machine.
• NEVER allow the unit to run with
the trigger released (off) for more
than one minute. Resulting heat
buildup will damage the pump.
• NEVER store the pressure washer
outdoors or where it could freeze.
Freezing temperatures can seriously
damage the pump.
• Release the trigger when changing
from high to low pressure modes.
Failure to do so could result in damage to the nozzle.
Keep hose away
from sharp objects.
Bursting hoses may cause injury.
Examine hoses regularly and replace if
damaged. Do not attempt to mend a
damaged hose.
