ATTENDED DURING OPERATION.
17. The best insurance against an accident is precaution, and knowledge of the machine.
18. Do not operate this product when fatigued or under the influence of alcohol or drugs. Keep operating area clear of all persons.
19. We will not be liable for any changes made to our
standard machines, or any components not purchased from us.
20. Do not overreach or stand on unstable support.
Keep good footing and balance at all times.
21. Follow the maintenance instructions specified in
the manual.
22. When making repairs disconnect from electrical
source.
23. Before disconnecting high pressure hose from
hot water outlet, turn off burner to allow water to
cool to 100°F, then turn off pump motor and water
supply and operate spray gun to relieve back pressure in hose. This will prevent coil damage from
thermal expansion.
CAUTION: This machine produces hot water and
must have insulated components attached to protect the operator.
CAUTION: Inspect rupture disc and pressure relief
devices annually for any obstruction.

INSTALLATION
Place machine in a convenient location providing ample
support, draining and room for maintenance.
This machine is intended for outdoor use. Machine
must be stored indoors when not in use.
Location:
The location should protect the machine from damaging environmental conditions, such as wind, rain, and
PRESSURE WASHER
freezing.
1. This machine should be run on a level surface
where it is not readily influenced by outside sources
such as strong winds, freezing temperatures, rain,
etc. It should be located to allow accessibility for
refilling of fuel, adjustments and maintenance.
Normal precautions should be taken by the operator of the machine to prevent moisture from reaching the electrical controls.
2. It is recommended that a partition be made be-
OPERATOR’S MANUAL
tween the wash area and the machine to prevent
water spray from coming in contact with the machine. Excess moisture reaching any electric components or electrical controls will reduce machine
life and may cause electrical shorts.
3. During installation of the machine, beware of poorly
ventilated locations or areas where exhaust fans
may cause an insufficient supply of oxygen. Sufficient 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 machine in a poorly ventilated area, outside fresh air may have to be piped to the burner
and a fan installed to bring air into the machine.
Avoid small locations or areas near exhaust fans.
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away from walls should be adequate.)
Water Source:
The water source for the pressure washer should be
supplied by a minimum 5/8" I.D. garden hose with a
city water pressure of not less than 30 PSI. If the water
supply is inadequate, or if the garden hose is kinked,
the attached pressure washer will run very rough and
the burner will not fire.
Connection:
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon tape
to avoid water leaks. (See Component Identification).
Venting:
Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes carbon build-up, which affects the operation, and increases
maintenance on the coil. If a stack must be used, refrain from using 90° bends. If the pipe can not go straight
up then use only 45° bends and go to the next size
pipe. The overall pipe length must not exceed 6 feet in
length*.
*Note: After vent pipe installation test burner using a
smoke tester and adjust air setting to achieve a #3 or
below results.

STEP 2: Use detergent designed
specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent
solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the
filter end of detergent suction tube
into the detergent container.
STEP 4: With the engine running,
pull trigger to operate machine.
Liquid detergent is drawn into the
machine and mixed with water.
Apply detergent to work area. Do
not allow detergent to dry on surface.
THERMAL PUMP
PROTECTION
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal device prevents internal damage to the pump.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. If surface appears to
be drying, simply wet down surface with fresh water. If
needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may remove
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine and other corrosive chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desired high pressure nozzle. NOTE: You can also
stop detergent from flowing by simply removing detergent siphon tube from bottle.
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high temperatures. When the water reaches this temperature, the

SHUTTING DOWN AND CLEAN-UP
STEP 1: Remove detergent suction
tube from container and insert into
1 gallon of fresh water. Turn variable
pressure wand handle for low pressure or connect the black detergent
nozzle. Pull trigger on spray gun and
siphon water for one minute.
STEP 2: Turn burner switch off and
continue spraying water, allowing the
water to cool. After water has cooled
to less than 100°F, turn the attached
pressure washer off.
STEP 3: Turn off water supply.

OPERATOR’S MANUAL
STEP 4: Open the spray gun to re-
lieve remaining pressure.
STORAGE
CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun trigger to release pressure.
2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until remaining water exits. Turn motor off immediately.
4. Drain the fuel from the fuel tank.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room which
does not reach freezing temperatures.
CAUTION: Failure to follow the above directions will
result in damage to your pressure washer.
When the pressure washer is not being operated or is being
stored for more than one month, follow these instructions:
1. Replenish pump oil to upper level.
2. Drain fuel from fuel tank, fuel line and filter.
3. Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open flame or
sparks.
After Extended Storage
CAUTION: Prior to restarting, thaw out any
possible ice from pressure washer hoses,
spray gun or wand.
