Grounding Instructions
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electrical shock. This product is equipped with a cord having
an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet
that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER - Improper connection of the equipment - grounding conductor can result in a risk of electrocution.
Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet
installed by a qualified electrician. Do not use any type adapter with this product.
1. For a product rated 125 volts or less:
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
This pressure washer is provided with a ground fault circuit interrupter (GFCI) built into the plug of the power
supply cord. This device provides additional protection from the risk of electric shock. Should replacement of
the plug or cord become necessary, use only identical replacement parts that include GFCI protection.
2. For a product rated more than 125 volts:
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
To comply with the National Electric Code (NFPA 70) and to provide additional protection from the risk of
electric shock, this pressure washer should only be connected to a receptacle that is protected by a ground
fault circuit interrupter (GFCI).
Extension Cords
Use only 3-wire extension cords that have 3 prong grounding-type plugs and 3-pole cord connectors that
accept the plug from the product. Use only extension cords that are intended for outdoor use. These extension
cords are identified by a marking “Acceptable for use with outdoor appliances; store indoors while not in use.”
Use only extension cords having an electrical rating not less than the rating of the product. Do not abuse
extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp edges.
Always disconnect the extension cord from the receptacle before disconnecting the product from the extension
cord.
Warning - To reduce the risk of electrocution, keep all connections dry and off the ground. do not touch plug
with wet hands.

Operation Instructions
Water Supply
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.
Model
Time to fill 5 gallon bucket
150 seconds
1573001
1573011
1573021
160 seconds
96 seconds
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 115 psi
(8 bar).
5.) Always use a flexible rubber hose for your water supply. Do not use rigid piping.

-Do not check for leaks with hand. Instead, use a piece of cardboard to check for
leaks.
-Do not use unit if exterior hose damage is evident. Make sure all fittings are tight
before starting. Relieve system pressure before servicing.
-Know how to stop engine and bleed pressures quickly. Be thoroughly familiar with
the controls.
-Make sure accessories meet the unit's temperature and pressure limits.
-Stop engine and bleed pressures before leaving unit unattended.

Operation Instructions
Applying Chemicals
1.) Install the black nozzle when applying chemicals onto the cleaning surface.
2.) Start the pressure washer according to the start-up instructions.
3.) Submerge the chemical hose in cleaning solution. (See Pump Component Identification section
for chemical injector location.)
4.) Squeeze the spray gun trigger. The chemical injector will draw the chemical into the water
stream.
5.) Apply chemicals evenly onto the cleaning surface. Allow the chemicals to react with the dirt, then
clean at high pressure with high pressure (green or yellow) nozzle.
6.) Never use more chemical than is necessary to clean the surface.
7.) To clean the chemical injector, draw water through the strainer until all the chemical is purged
from the system.

Maintenance and Storage
Pump Oil Change
1.) Place a suitable container below the pump to catch the used oil, then remove the oil fill cap and oil
drain plug.
2.) Allow the used oil to drain completely, then reinstall the drain plug and tighten securely.
3.) Please dispose of used oil in a manner that is compatible with the environment. We suggest you
