GROUNDING INSTRUCTIONS

This product must be grounded. If it should malfunction or break down,
grounding provides a path of least resistance for electric current to reduce
the risk of electric 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 USE ANY TYPE OF ADAPTOR WITH THIS PRODUCT.

GROUND FAULT CIRCUIT INTERRUPTER PROTECTION:
GPW-1200/GPW-1000/GPW-2003/2502

These pressure washers are provided with a ground fault circuit interrupter
(GFCI) built into 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. (GPW-2003-3 and GPW-2502-3 three phase units do not have
GFCI and must be connected to one).

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 use damaged extension cords.
Examine extension cord before using and replace if damaged.

Do not abuse extension cord and do not yank on any cord 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.

CAUTIONS: GPW-1200/GPW-1000/GPW-1000-P

1. When machine is shut down, a small amount of water is left in pump
and plumbing; therefore, THE MACHINE MUST NOT BE STORED UNDER
FREEZING CONDITIONS. If necessary, a small amount of antifreeze may

be pumped through the system if machine is left in cold storage.

2. Do not run pump dry.

3. When pump is running without spraying, the bypass valve allows the
water to circulate around the pump. This condition will gradually elevate the
temperature of the water through friction, and overheating will
damage the pump seals. Therefore, THE PUMP MUST BE ALLOWED

TO RUN MORE THAN 10 MINUTES WITHOUT SPRAYING.

3

4. The Goodway GPW-1000 and GPW-1000P may be used with warm water
supply at a maximum of 180°F (82°C), and the GPW-1200 at a maximum of
140°F (60°C) to improve cleaning. IF WARM WATER SUPPLY IS USED, THE
TIME IN NO. 3 SHOULD BE REDUCED FURTHER.

5. Since the high pressure spray is very powerful, DO NOT AIM AT OR SPRAY

HUMANS OR ANIMALS.

6. Do not operate without eye protection.

CAUTIONS: GPW-2003/GPW-2502

1. Avoid exposing the machine to freezing temperatures as the pump can be
severely damaged if water is allowed to freeze in it. If the unit must be ex­posed to freezing, run pump dry approximately 10 seconds to drain the pump.

2. Do not run the pump dry.

3. The GPW-2003 and GPW-2502 may be connected to a warm water
supply at a maximum of 160°F (71°C) to improve cleaning action. (See
“MAINTENANCE” for further information regarding warm water operation).

4. Since the high pressure spray is very powerful, DO NOT AIM AT OR SPRAY

HUMANS OR ANIMALS.

5. Do not operate without eye protection.

6. The GPW-2003 and GPW-2502 can only be run in the vertical position.

7. To avoid inadvertent operation, turn power off when the unit is not used for
an extended period of time or when the unit's operator departs the area.

ASSEMBLY INSTRUCTIONS: GPW-1200

The GPW-1200 comes virtually ready to use. Final assembly requires only
the connection of the gun/wand and high pressure hose using the quick
disconnect fitting. Insert the dip tube into the chemical container.

ASSEMBLY INSTRUCTIONS: GPW-1000

1. Place power unit on bench or floor with louvers down. Place dolly
assembly on back and insert the two plastic thumbscrews through the
tapped holes on the back of the power unit.

2. Turn the machine upright and connect the end of the high pressure hose to
the quick disconnect fitting on the top of the machine.

3. Assemble water connection fitting in front bottom edge of cover and
carefully thread onto nipple (P/N 1004). Tighten securely.

4. Place chemical container (if used) on top of unit inside the retaining bail and
place dip tube inside container. Make sure dip tube strainer is attached to
dip tube.

ASSEMBLY INSTRUCTIONS: GPW-1000-P

1. Place power unit on bench or floor with louvers down. Place dolly assembly
on back and insert the two thumbscrews through the tapped holes on the
back of the power unit.

2. Assemble water connection fitting in front bottom edge of cover and
carefully thread onto nipple (P/N 1004). Tighten securely.

3. Place chemical container (if used) on top of unit inside the retaining bail and
place dip tube inside container. Make sure dip tube strainer is attached to
dip tube.

4. Connect the high pressure hose to the quick disconnect fitting on the top of
the machine. Connect air hoses to valves (P/N 1060) – either air hose can be
connected to either valve.

ASSEMBLY INSTRUCTIONS: GPW-2003/GPW-2502

1. Remove the unit from the packing material and inspect for damage.

2. Ensure there is sufficient oil in the pump by inspecting the window on
the back of the unit.. Oil level should be in the middle of the window.

DO NOT OVERFILL!

3. Connect the end of the high pressure hose to the fitting on the side of

the machine.

OPERATING INSTRUCTIONS: GPW-1200

1. Connect water hose capable of delivering a minimum of 1.8 GPM
(6.8 LPM) to inlet and turn on faucet. Consult the Goodway catalog for
heavy-duty water supply hose. DO NOT RUN PUMP DRY.
