GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or break
down, grounding provides a path of least resistance for the 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 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 of adapter with this product.
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

CAUTIONS
1. Avoid exposing the machine to freezing temperatures as the
pump housing and heating coil may crack if water is allowed to
freeze in the unit. If the unit must be exposed to freezing
conditions, follow the instructions under COLD WEATHER
STORAGE.
2. DO NOT RUN THE PUMP DRY FOR MORE THAN 15
SECONDS.
3. When the pump is running without spraying, the bypass valve
allows the water to circulate around the pump. This condition
will gradually elevate the temperature through friction. Frequent
or prolonged bypass can result in high temperature build-up.
These high temperatures can cause premature failure of the
pump. RUNNING THE PUMP WITHOUT SPRAYING FOR
MORE THAN A FEW MINUTES IS NOT RECOMMENDED.
Do not attempt to change the factory settings of the bypass
valve or the nozzle orifice size. Doing so may create an unsafe
condition and shorten the life of the pump.
4. Do not spray water onto the machine housing or into the boiler
as serious damage can result, voiding the warranty.
5. Do not smoke while filling fuel tank. Do not use this product
where flammable liquids or vapors are present.

ELECTRIC MOTOR
The HPW-1000 is powered by a 1.5 HP (1.1 kW), 115 V, 60 HZ,
single phase electric motor. The HPW-2000 is powered by a 3 HP
(2.2 kW), 220 V, 60 HZ, single phase electric motor. The HPW2000-3 is powered by a 5 HP (3.7 kW), 220 V, 60 HZ, three phase
electric motor. The HPW-1000 and HPW-2000 are equipped with
thermal overload protection. The motor drives a three-plunger oil
bath pump. Should the motor overheat, the thermal overload will
cut off power to the motor. The overload is manually reset. The
reset button is located on the side of the motor. ALWAYS
DETERMINE AND CORRECT THE CAUSE OF THERMAL
OVERLOAD BEFORE USING THE MACHINE AGAIN.
NOTE: The HPW-2000-3 is not equipped with thermal overload
protection.
ABOUT THE OIL BURNER/BOILER
These units are equipped with an oil-fired boiler, which can be
fired on #1 or #2 fuel oil or diesel fuel. Kerosene is not
recommended. Most burner service can be performed locally by a
qualified oil burner service technician.
NEVER REMOVE THE BURNER HOUSING FROM THE
UNIT AS DAMAGE TO THE BOILER INSULATION WILL
RESULT. ALL BURNER SERVICE CAN BE PERFORMED
WITH THE BURNER HOUSING IN PLACE.
WARNING
: NEVER PUT GASOLINE IN THE BURNER
FUEL TANK.
WARNING
: DO NOT WRAP HOSES OR ELECTRICAL
CORDS AROUND THE BOILER HOUSING. DAMAGE
AND SERIOUS INJURY MAY RESULT
6

BOILER/BURNER SAFETY - ALL MODELS
1. Keep combustible materials a minimum of 48" (1200 mm)
from the sides of the boiler housing.
2. Do not install a stack pipe on this product as it will impede
airflow resulting in poor combustion and possible release of
harmful fumes.
3. Do not exhaust gasses into a wall, ceiling, or confined space.
4. The use of a ducted exhaust hood is recommended for indoor
operation. Otherwise, place the power unit outside the
building. Do not, however, expose the machine to rain.
5. Always be mindful that there is an open flame at the top of the
boiler when the burner is firing. Keep hands, hair, clothing and
other combustible materials away.
FUEL OIL FILTER
These machines are equipped with a micron fuel oil filter, which is
located on the fuel oil line under the machine housing. The fuel oil
tank is also equipped with a filter to trap larger pieces of debris,
which may get into the fuel oil supply. The micron filter should be
changed and the fuel oil tank cleaned annually.
7
7
HEATING COIL
The heating coil in the boiler is constructed of high quality 1/2"
(13mm) ID Sch. 80 steel tubing for long service. Proper care of
the coil will maximize its life. Care should be taken to prevent
objects from falling into the heating coil. Such objects could cause
poor burner performance. In cases where very hard water is used,
mineral scale can build up and restrict the water flow through the
coil. It may be necessary to descale the coil annually. A coil
descaler (part # HPW-DSC) is available from Goodway
Technologies Corp.
PUMP LUBRICATION
These units are equipped with an oil bath pump. When shipped,
the crankcase is filled with the proper amount of oil. Due to the
possibility of spillage in shipment, the oil level should be checked
prior to the first use of the machine, as well as prior to each use.
With the machine resting on a level surface, the correct oil level
should reach the middle of the sight glass on the side of the pump.
If the oil level is low, add sufficient oil to the crankcase. DO NOT
OVERFILL.
The high-pressure pump crankcase takes Cat Pump Oil or premium
10W30 hydraulic oil (not motor oil). Cat Pump Oil (HPW-CPO)
is available from Goodway Technologies Corp.
CHANGING PUMP OIL
Pump oil should be changed after the first 50 hours of operation
and then after every 50 -100 hours.
8
8
GETTING READY
1. Check all oil level before any operation to ensure good start up
and problem free performance.
2. Connect a clean water hose capable of delivering 2 GPM (7.6
LPM) for the HPW-1000, 2.2 GPM (8.3 LPM) for the HPW2000, or 4 GPM (15.1 LPM) for the HPW-2000-3 to the garden
hose fitting located on the pump inlet. Make sure the screen
washer is clean and in place. Consult the Goodway catalog for
heavy-duty water supply hose (part # WSH-R50).
NOTE: Any restriction in the water supply may cause
cavitation and pump damage. Positive inlet pressure above 25
PSI (1.7 BAR) is required to avoid cavitation. DO NOT RUN
DRY.
3. Connect the high-pressure hose to the outlet fitting located on
the side of the boiler housing.
4. Connect the gun to the high-pressure hose.
5. Insert the dip tube into a container of soap or chemical, if used.
See " SOAP OR CHEMICAL APPLICATION" for a more
detailed explanation on using soap or chemicals.
6. Turn on the water supply, and with no quick disconnect nozzle
in place, trigger the gun for a few minutes to allow trapped air,
dirt particles or mill scale to escape from the system. Reinstall
the desired quick disconnect nozzle.
NOTE: Always be sure when operating the machine that the
nozzle is not clogged or restricted in any way.
CAUTION: ALWAYS ENGAGE THE TRIGGER LOCK WHEN
CHANGING NOZZLES.
9
9
OPERATION
These models are equipped with a three-position switch:
Position #1 - off position.
Position #2 - pump on for cold water washing
Position #3 - burner on for hot water washing
1. Trigger the gun and turn the main switch to position #2. Allow
the unit to attain full pressure.
2. If desired, turn the main switch to position #3 for hot water
washing.
The Goodway Hot Water Pressure Washers use a double wand
with a low pressure nozzle for chemical application mounted on
one wand and a fitting for quick disconnect high pressure nozzles
on the other. The units are supplied with 4 quick disconnect
nozzles - a 0o pinpoint spray, a 15o fan spray, a 25o fan spray and
a 40o fan spray. The low-pressure nozzle activates the siphon
injector to draw soap or chemical into the water stream. The highpressure nozzles are used for rinsing. To switch from one nozzle
to another simply:
1. Release the trigger to stop the spray action and engage the
trigger lock.
2. Pull back the locking collar to release the nozzle.
3. Insert another nozzle until the locking collar snaps into place.
CAUTION: NOZZLES MAY BE HOT.
SOAP OR CHEMICAL APPLICATION
1. Place the strainer end of the siphon hose into your container of
premixed chemical solution. The siphon injector draws at a
rate of 1 part chemical to 8 parts water when the soap valve is
wide open. Dilute your chemical, if necessary, to the proper
level to obtain the final ratio recommended by the chemical
10
10
manufacturer. ALWAYS USE LIQUID CONCENTRATES
TO PREVENT CLOGGING THE SIPHON INJECTOR.
2. Chemicals are applied at low pressure and are drawn through
the water system of the machine. Application is controlled by
the valve on the wand. Turning the handle on the left side of
the wand counter clockwise (or away from you) will start and
gradually increase the chemical draw. Turning the handle
clockwise (or towards you) will decrease and eventually shut
off the chemical draw. It takes several seconds for the
chemical to travel through the boiler coil and high-pressure
hose to the nozzle. Chemical application is not instantaneous
and chemical spray continues for several seconds after
switching to high pressure.
SHUTDOWN
When shutting down from hot water operation, allow the boiler to
cool gradually. Move the main switch to the cold water washing
position (#2 ) and leave the gun trigger open for a few minutes
before turning the machine completely off. Once the unit is turned
off, trigger the gun to relieve pressure.
COLD WEATHER STORAGE
If the machine must be stored in an area subject to freezing
temperatures, observe the following instructions:
1. Prepare a five-gallon pail with at least three gallons of anti-
freeze mixture.
2. Run a feed hose from the pail to the pump inlet.
3. Place the end of the wand in the pail and trigger the gun.
4. Run the unit in the cold water wash mode until the anti-freeze
mixture is seen discharging from the wand. The machine,
hose, gun and wand are now protected
against freezing.
11
11
PUMP REPAIRS
When pump repairs are required, the pump, bypass valve and
plumbing can be removed from the unit and sent to the factory for
repair. Customer repair of the pump is not recommended as
improper reassembly of the pump can result in an unsafe condition.
In addition, often times problems that seem to be pump related are
caused by faulty bypass valves or other components in the pressure
system. It is not necessary to return the entire machine to have
pump repairs performed.
FACTORY REPAIR OF THE BYPASS VALVE IS
RECOMMENDED. IF THE BYPASS VALVE IS NOT
PROPERLY ADJUSTED, PUMP DAMAGE CAN RESULT.
NEVER CHANGE THE FACTORY SETTING OF THE
BYPASS VALVE.

hot water washing. Operating in position #3 activates the
battery charging system.
WARNING: NEVER START THE MACHINE WITH THE
SWITCH IN POSITION #3 OR POSITION #4. THIS WILL
DAMAGE THE MACHINE AND VOID THE WARRANTY.
The Goodway Hot Water Pressure Washers use a double wand
with a low pressure nozzle for chemical application mounted on
one wand and a fitting for quick disconnect high pressure nozzles
on the other. The units are supplied with 4 quick disconnect
nozzles - a 0o pinpoint spray, a 15o fan spray, a 25o fan spray and
a 40o fan spray. The low-pressure nozzle activates the siphon
injector to draw soap or chemical into the water stream. The highpressure nozzles are used for rinsing. To switch from one nozzle
to another simply:
26
26
1. Release the trigger to stop the spray action and engage the
trigger lock.
2. Pull back the locking collar to release the nozzle.
3. Insert another nozzle until the locking collar snaps into place.
CAUTION: NOZZLES MAY BE HOT.
SOAP OR CHEMICAL APPLICATION
1. Place the strainer end of the siphon hose into your container of
premixed chemical solution. The siphon injector draws at a
rate of 1 part chemical to 8 parts water when the soap valve is
wide open. Dilute your chemical, if necessary, to the proper
level to obtain the final ratio recommended by the chemical
manufacturer. ALWAYS USE LIQUID CONCENTRATES
TO PREVENT CLOGGING THE SIPHON INJECTOR.
2. Chemicals are applied at low pressure and are drawn through
the water system of the machine. Application is controlled by
the valve on the wand. Turning the T-handle on the left side of
the wand counter clockwise (or away from you) will start and
gradually increase the chemical draw. Turning the handle
clockwise (or towards you) will decrease and eventually shut
off the chemical draw. It takes several seconds for the
chemical to travel through the boiler coil and high-pressure
hose to the nozzle. Chemical application is not instantaneous
and chemical spray continues for several seconds after
switching to high pressure.

SHUTDOWN
When shutting down from hot water operation, allow the boiler to
cool gradually. Move the main switch to the cold water washing
position (#3 ) and leave the gun trigger open for a few minutes
before turning the machine completely off. Once the unit is turned
off, trigger the gun to relieve pressure.
COLD WEATHER STORAGE
If the machine must be stored in an area subject to freezing
temperatures, observe the following instructions:
1. Prepare a five-gallon pail with at least three gallons of anti-
freeze mixture.
2. Run a feed hose from the pail to the pump inlet.
3. Place the end of the wand in the pail and trigger the gun.
4. Run the unit in the cold water wash mode until the anti-freeze
mixture is seen discharging from the wand. The machine,
hose, gun and wand are now protected against freezing.
PUMP REPAIRS
When pump repairs are required, the pump, bypass valve and
plumbing can be removed from the unit and sent to the factory for
repair. Customer repair of the pump is not recommended as
improper reassembly of the pump can result in an unsafe condition.
In addition, often times problems that seem to be pump related are
caused by faulty bypass valves or other components in the pressure
system. It is not necessary to return the entire machine to have
pump repairs performed.
FACTORY REPAIR OF THE BYPASS VALVE IS
RECOMMENDED. IF THE BYPASS VALVE IS NOT PROPERLY
ADJUSTED, PUMP DAMAGE CAN RESULT. NEVER CHANGE
THE FACTORY SETTING OF THE BYPASS VALVE.
