unstable ground.

8.) Follow the maintenance instructions specified in all manuals. Do not run machine without sufficient
lubrication or sufficient water to cool the pump.

9.) Wear safety glasses, gloves, face protection and appropriate clothing when operating the machine.

10.) Do not operate this machine with broken or missing parts - Never alter the manufacturer’s original design
or deactivate any safety device on the machine.

11.) Risk of exposure to dangerous chemicals. Wear protective gloves when handling and cleaning with
chemicals. Follow the chemical manufacturer’s directions. Understand all safety hazards and first aid for
all chemicals being used. Check whether dangerous chemicals have been used and take any
precautions that may have been recommended by the supplier of these chemicals when cleaning filters.
Do not pump highly abrasive fluids or use with incompatible chemicals or solvents.

12.) Know the pressure and temperature limits of your machine. Be sure all high pressure accessories meet
or exceed your machine’s limits. Do not set the pressure relief valve above the machine’s limit.

13.) Do not move this machine by pulling on the hose. Do not use the pump to support other items of

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.

IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life and lower maintenance cost.

Make sure the pressure washer is on a level surface and
in a protected area where it is not readily influenced by
outside forces such as strong winds, freezing
temperatures, rain, etc. Locate the pressure washer for
easy access for filling fluids, adjustments and
maintenance.
It is recommended that a partition be made between the
wash area and the pressure washer to prevent direct
nozzle spray from coming in contact with the pressure
washer. Moisture reaching the equipment will reduce the
pressure washer’s service life.

V.) Venting

DANGER: Do not run machine indoors or in an
enclosed area without adequate ventilation or in
areas where flammable vapors (gasoline, solvents,
etc.) may be present. Do not vent exhaust gases into
a wall, a ceiling or a concealed space.
CAUTION: All venting must be in accordance with
applicable federal and state laws and local
ordinances. Consult local heating contractors.

Poor draft will cause the pressure washer to soot and not
operate properly. When selecting the location for
installation, beware of poorly ventilated locations or areas
where exhaust fans may cause an insufficient supply of
oxygen. Proper combustion can only be obtained when
there is a sufficient supply of oxygen available for the
amount of fuel being burned. If it is necessary to install a
unit in a poorly ventilated area, outside fresh air may
have to be piped to the burner and a fan installed to bring
sufficient air into the unit

VI.) Oil Burner

Burner Air Adjustment: The oil burner is preset and
performance tested at the factory (elevation 1100 feet).
A one-time initial correction of the burner for your
location will pay off in economy, performance and
extended service life.

1.) Turn the pump and heat switches on (Refer to

“Operation” for details). Have someone operate the

spray gun so the burner fires.

2.) Loosen the locking screw and close the air band until
black smoke appears from the burner exhaust vent.
Note the position of the white arrow on the air band.

3.) Slowly open the air band until white smoke just starts
to appear.

4.) Turn the air band half way back to the black smoke
position previously noted. Tighten the locking screw.

5.) Fine tune the burner air by loosening the shutter lock
screw and turning the shutter until the exhaust is
cleanest. Tighten the shutter lock screw.

CAUTION: If white smoke appears from the burner
exhaust vent during start-up or operation,
discontinue use and readjust air bands.
