Special Equipment Safety Features
Pump Thermal Relief Valve
This unit is equipped with the following safety features:
This valve, on the Unloader bypass port, protects the
pump from overheating. The pump continues to work in
bypass mode when you are not spraying. If high
temperatures are developed during bypass mode, the
Thermal Relief Valve will open and discharge hot water
onto the ground, protecting the pump from overheating.
High Pressure Safety Device (Rupture Disc)
Acts as a backup safety feature. If the Pressure Control
Valve (Unloader) malfunctions, this separate highpressure safety device will open and relieve excess
system pressure. Repair is required.
WARNING: Rupture Disc failure

through a hood or piped to the outside.
 Place the unit so that the exhaust fumes will not
be directed towards people or building air intakes.
Precautions:
 Keep a fire extinguisher rated “ABC” nearby.
Keep it properly charged and be familiar with its
use.
 Ensure that working, battery-operated or battery
back-up carbon monoxide alarms are used in any
structure that is in close proximity to the running
pressure washer.
 An abundant amount of air must be available for
proper combustion and cooling. Do not install in
small, enclosed areas without an ample
circulation of supply air.
DANGER: Carbon monoxide poisoning
hazard
Exhaust fumes from the burner contain carbon
monoxide (CO), a poisonous gas you cannot see,
smell, or taste. The CO generated by the pressure
washer can rapidly accumulate, even in areas that
appear to be well ventilated, resulting in dangerous and
fatal concentrations within minutes. ONLY run pressure
washer outdoors and away from air intakes. NEVER run
pressure washer inside any enclosed or semi-enclosed
spaces, including homes, garages, basements, sheds,
boxes, pick-up truck beds, RVs, or boats. These spaces
can trap poisonous gases, EVEN if you run a fan or
open windows. If you start to feel sick, dizzy, or weak
while using the pressure washer, shut off the motor and
get to fresh air RIGHT AWAY. See a doctor. You may
have carbon monoxide poisoning.

Keep spray away from electrical wiring. Spray
contact with electrical wiring will likely result in severe
electrical shock or electrocution.
Used For:
Keep spray away from people. Never direct discharge
stream at or near any person. Do not allow any part of
the body to come in contact with the fluid stream.
Prevent surface damage & flying debris. Surfaces
being sprayed must be strong enough to withstand highpressure spray, or damage may result. In addition, highpressure spray will dislodge unsecured objects, surface
chips, and debris, resulting in hazardous flying objects
that can cause personal injury or property damage. Do
not spray brittle surfaces or breakable, fragile,
unsecured objects, such as:
 Stucco or laminar flagstone
 Some painted surfaces
 Windows or glass doors (because they may
break)
 Light fixtures, flowerbeds, mailboxes
 Unsecured, lightweight objects
Note: Use only the black low-pressure nozzle for
spraying chemicals, which provides the proper mixing
ratio.

Safety
Latch
00417
Disengage safety latch and start spraying at the top
using long, even, side-to-side, overlapping passes.
The pressure washer is set and locked to the
maximum rated pressure when it leaves the factory.
To reduce the pressure, turn the Unloader knob
counterclockwise (Figure 12).
Never run the machine without sufficient pump oil or
sufficient water to cool the pump.
Hold the spray gun firmly with two hands and a sturdy
stance (gun kicks back when triggered).
Nozzle should be 12” to 24” from the work, closer for
tough areas.
17
Chemical Spraying Procedure:
 Disengage safety latch and apply chemicals
evenly to the cleaning surface working from
bottom upward, using long, even, overlapping
passes.
 Allow chemicals time to react with dirt before
rinsing. Do not allow the chemical to dry on,
reapply as needed to prevent surface from drying.
Rinsing:
 Change to a high-pressure nozzle for rinsing.
Changing to a high-pressure nozzle will
automatically stop the flow of chemicals into the
water stream.
 Rinse with high-pressure spray, either hot or cold.
CAUTION: Chemical mixture
The special NorthStar braided chemical hose when
placed within a liquid and attached at the pump’s
chemical injection port will inject 1 part chemical to 15
parts water. Chemicals must be pre-diluted in
accordance to instructions to accommodate the
additional 15:1 dilution ratio which will occur in the
pump.
Chemical Spraying Preparation:
 Prepare (dilute) cleaning solution as required for
the job. (Recall that this chemical solution will be
automatically mixed in the pump with water at a
ratio of 15 parts water to 1 part diluted chemical
solution.)
 Press braided chemical hose over the pump’s
chemical injector.
 Submerge suction strainer connected to braided
chemical hose into chemical solution bucket.
 Make sure the BLACK nozzle is attached to spray
wand before beginning to spray chemicals –
High-pressure nozzles cannot apply chemicals.
 Warm or cold water can be used. If warm water
is specified on chemical label, start burner
according to the instructions in the following
section, “Hot Spray Procedure.”


Turn heat switch ON and adjust thermostat to desired
temperature. (For steam spraying, set temperature at
212F or higher and use YELLOW nozzle.)
Burner will only fire as trigger is squeezed – follow
instructions for spraying.

Hot Spray Procedure
CAUTION: Metal burn hazard
Use of burner will make spray gun hot. Avoid touching
wand. Serious burns from hot metal could occur if
touched.



Before starting burner, make sure vicinity is free of
flammable vapors, dust, gases, or other potentially
combustible materials. Operate only where open
flame or torch is permitted and neither flammable
vapors nor combustible objects are present.
Ensure there is fuel in burner fuel tank.
Wait before re-lighting burner. NEVER attempt to
immediately re-light the burner if it doesn’t ignite the
first time. Unburned oil or gas may have
accumulated, causing potential explosion or fire
hazard.
Burner automatically turns off when trigger is
released or when temperature setting is reached.
Note: If burner exhaust is white, adjust burner for
peak performance. See “Oil Burner Adjustment”
section towards the back of this manual.
18
Step 4. Stopping
DANGER: Carbon monoxide poisoning
hazard
If the heater was used, turn heat switch OFF and run
cold water through the coil for at least 2 minutes while
spraying. If no heater, you may immediately:
 Turn power switch OFF.
 Turn water supply OFF.
 Actuate spray gun trigger to relieve system
pressure.
 Remove garden hose, pressure hose and nozzle
 Unplug pressure washer.
 Let machine cool for 5 minutes and store in a
clean, dry area until next use. See “Storage”
section for more details.
 If storing for more than 30 days, see “Long Term
Storage.”
Exhaust fumes from the burner contain carbon
monoxide (CO), a poisonous gas you cannot see,
smell, or taste. The CO generated by the pressure
washer can rapidly accumulate, even in areas that
appear to be well ventilated, resulting in dangerous and
fatal concentrations within minutes. ONLY run pressure
washer outdoors and away from air intakes. NEVER run
pressure washer inside any enclosed or semi-enclosed
spaces, including homes, garages, basements, sheds,
boxes, pick-up truck beds, RVs, or boats. These spaces
can trap poisonous gases, EVEN if you run a fan or
open windows.
Storage
Between-Use Storage
Note: Long-term storage is treated differently than
between-use storage.
Before storing, let machine cool for at least 5 minutes,
as a hot engine can be a fire hazard. Place in a secure
location where it will not be started by untrained
persons.
Do not allow water to freeze in the pressure washer,
high-pressure hose, or spray gun. Freezing water will
cause damage to the equipment and can cause the
spray gun to fail in the open position. A spray gun that
has failed in the open position can whip around and
cause personal injury when the pressure washer is
started. Winterize as follows:
1. Drain the water from the high pressure hose and
spray gun by pressing the trigger on the spray
gun until all water drains out.
2. Using a wrench, disconnect the plumbing that
connects to the pump outlet.
3. Obtain the materials you will need:
 12” piece of garden hose or equivalent
 Funnel
 Approximately 6 oz. of RV antifreeze.
4. Attach the 12” garden hose piece with the funnel
to the pump inlet (Figure 14).
5. Pour RV antifreeze into the
funnel, then turn starter
(or pull the recoil) a
few times until
antifreeze comes out
of the pump outlet.
An appropriate storage location is:
 Clean and dry.
 Away from sources of heat, open flames, sparks
or pilot lights, even if the and burner fuel tank is
empty. (Residual fuel vapors from tank can
ignite.)
 Away from extreme high or low temperatures.
(Do not store the unit in freezing conditions
unless it is prepared as directed in “Winter
Storage Preparation.”)
Long-Term Storage Preparation (between
infrequent uses and at end of season)
Prepare for long-term storage if you will not be using
machine again for more than 30 days. Fuel can become
stale when stored over 30 days. Stale fuel causes acid
and gum deposits to form in the fuel system which can
cause the machine to malfunction. To avoid problems,
the fuel system should be emptied or treated with a fuel
preserver before storing the machine longer than 30
days.
Winter Storage Preparation
Machines containing water for cooling or those that use
water during operation need special preparation for
storage during the winter (or freezing) months to prevent
water from freezing in the system.

WARNING: High pressure fluid injection
hazard
High-pressure fluid discharge from leaks (even pinsized) or ruptured components can pierce skin and
inject fluid into the body. Injection injury can result in
blood poisoning and/or severe tissue damage leading to
infection, gangrene, and possibly amputation.
Do not spray pressure washer with a garden hose or
pressure washer to clean. Water may enter parts of the
pressure washer which will cause damage. Cleaning
should be done with a damp sponge with the motor
OFF.
 Never use a finger or skin to check for leaks.
 Never operate machine with damaged or missing
hoses/parts.
 Never attempt to repair a high-pressure hose or
component – Always replace it with a part that is
rated at or above the pressure rating of this
machine.

Descale Heating Coil
Clean Inlet Filter for Garden Hose




In hard water areas, scale can build up inside the
heating coil tubing. Scale deposits will decrease the
output pressure and temperature of heated spray, and
may eventually clog water flow through the heating coil.
Unscrew garden hose from water inlet (if connected).
Remove filter screen from water inlet.
Run water through filter screen to clean.
Reassemble.
Descale the coil tubing at least annually and more
frequently if you detect a decrease in output pressure or
temperature.
Check Tire Pressure




Remove air cap on tires.
Check tire pressure.
If needed, fill tire to 30 psi. Do not over inflate.
Replace air caps.
CAUTION: De-scaling burn hazard
Do not run the burner while de-scaling.
To Descale the Coil:
 Wear rubber gloves.
 Mix a commercial coil cleaner in a 5-gallon bucket
and elevate bucket so it is higher than the
unloader.
Change Pump Oil
After the first 40 hours of use, and then every 3 months
or 500 hours of use after that.
 Remove drain plug from pump. (See Figure 8
earlier in the manual.)
 Drain pump oil into suitable container and dispose
of according to local regulations.
 Reinstall oil drain plug.
 Make sure unit is sitting level. Fill pump with type
of pump oil specified below. (See “Specifications”
section of this manual to determine the type of
pump that came equipped with this pressure

Inspect Heating Coil and Desoot as Needed
Inspect and desoot coil annually. Although most coils
never require desooting, poor grades of fuel oil or
inadequate combustion air will cause heavy soot buildup on the outside surface of the heating coil tubing.
These deposits will insulate the coil, which then restricts
airflow through the heat exchanger and further
aggravates the soot build-up.

and improper handling may impair its performance. Please thoroughly read the instructions and understand the operation before using
your product. Always contact NorthStar Product Support at 1-800-270-0810 prior to having any service or warranty work performed,
as some services performed by parties other than NorthStar approved service centers may void this warranty. This warranty is in lieu
of any other warranty expressed or implied and NorthStar assumes no other responsibility or liability outside that expressed within this
warranty.

“Consumer use” means personal residential household use by a consumer. “Commercial use” means all other uses, including use for
commercial, income producing or rental purposes or when purchased by a business.
This warranty applies to the original purchaser of the equipment (verification of purchase, in the form of a receipt, is the responsibility
of the buyer), is non-transferable, and covers parts and labor. Parts will be replaced or repaired at no charge, except when the
equipment has failed due to lack of proper maintenance. If a part is no longer available, the part may be replaced with a similar part
of equal function. Any misuse, abuse, alteration or improper installation or operations will void warranty. Determining whether a
part is to be replaced or repaired is the sole decision of NorthStar. NorthStar will not provide for replacement of complete products
due to defective parts. Any costs incurred due to replacement or repair of items outside of a NorthStar approved facility is the
responsibility of the buyer and not covered under warranty. Transportation costs to and from service center is the responsibility of the
customer.
In addition to the normal warranty, NorthStar shall warrant any normal wear item from defects in material or workmanship for a
period of 90 days from the date of purchase by user. Normal wear items include, but are not limited to, nozzles, quick connect
fittings, valves, high and low pressure water seals/packing, high and low pressure hoses, O-rings, unloader valves and filter elements.
This warranty specifically excludes the following; failure of parts due to damage caused by accident, fire, flood, windstorm, acts of
God, applications not approved by NorthStar in writing, corrosion caused by chemicals, use of replacement parts which do not
conform to manufacturer’s specifications, damage related to the use of biodiesel fuel, damage related to rodent and/or insect
infestation and damage caused by vandalism. Additional exclusions: loss of running time, inconvenience, loss of income, or loss of
use, including any implied warranty of merchantability of fitness for a specific use. Also, Outdoor Power Equipment needs periodic
parts and service to perform well, and this warranty does not cover instances when normal use has exhausted the life of a component
or the engine.
This warranty does not cover any personal injury or damage to surrounding property caused by failure of any part. Repair or
replacement of parts does not extend the warranty period.
Normal burner maintenance such as cleaning and adjusting electrodes, descaling the coil, desooting the coil, air adjustments, fuel
system cleaning and obstruction due to build up is not covered by this NorthStar warranty.
Please fill in the following information and have it on hand when you call in on a warranty claim.
