PRESSURE WASHER
COOLING SYSTEM
DO NOT OVERHEAT YOUR MACHINE
Do not let your machine overheat. Failure to do so will result in damage, void
warranty, or cause injury.
Gas engines and electric motors are air-cooled. Always ensure that the machine
is operated in a well-ventilated area where it can draw a steady supply of fresh
air. If the motor overheats, it may shut down, rapidly burn oil, and result in
component failure. The arrows below show an example of locations for air intake
on an engine.
Pumps are cooled on the front end by having fresh water run into the pump,
then spray out of the gun wand. To maintain the water flow, keep the trigger of
the gun depressed to keep spraying out water. Do not let the machine run for
more than 30 seconds without pressing down on the trigger. If the pump is left to
overheat (not spraying water), it may experience thermal shock when cold water
is introduced to the system once water is sprayed out again. This thermal shock
can result in multiple component failures.
Most pumps are protected by a thermal valve. The thermal valve releases
water if a pump starts to run too hot. It will prevent catastrophic heat failure.
However, the pump may have suffered damage and need maintenance, repair, or
replacement. The thermal valve will need to be replaced once it is triggered.
The back end of the pump is cooled by maintaining the proper level and quality of
pump oil. Always check the oil level on the back of the pump by using the dipstick
or sight gauge. Use 30w non-detergent oil if it needs to be added or replaced.

FUEL AND OIL TYPES
ENGINE FUEL TYPE
Use only regular unleaded gasoline rated at 86 octane or higher. The best fuel
to use will have a 0% ethanol blend. However, the engine can use a fuel with an
ethanol blend of up to 10%.
ENGINE OIL TYPE
Use only SAE 10W30 motor oil for the engine. To check the oil, unscrew the
engine dipstick. Then, wipe off the oil with a clean rag and dip it back into the
engine. The oil should be well within the oil level markings.
Note* the engine will have two oil caps. Only one will have a dipstick.
PUMP OIL TYPE
For pressure washer pumps, use only SAE 30W non-detergent oil. Never use
motor oil in your pressure washer pump because it will destroy the seals.
Never overfill the pump.
• If your pump has a sight glass, then ll halfway up to the middle of the red dot.
• If your pump has a dipstick, then ll to the mark on the dipstick.
• If your pump doesn’t have a sight glass or dipstick, then it is a sealed unit, and
the owner doesn’t have to be concerned with maintaining the pump oil.

OPERATION
1. Before operating the pressure washer, ensure you are familiar with all the
warnings and safety recommendations.
2. Wear proper clothing and eye protection.
3. Always setup the machine where:
3.1 It is on a level surface. If the machine is not level, it may not start or cause
failures.
3.2 There is sucient ventilation.
3.3 There are no signs of oil or gas leaks, including gas vapors.
3.4 The machine is not exposed to rain, snow or freezing temperatures. These
harsh conditions can lead to component failure causing damage or injury.
4. Ensure that oil levels for the engine and pump are correct.
4.1 Use 10W30 oil to ll the engine if needed.
4.2 Use 30W non-detergent oil to ll the pump if needed.
5. If the pump has an oil cap dipstick, make sure it is the breathing oil cap
instead of the sealed travel oil cap. If the sealed travel oil cap is left in, the
pump will over pressurize and blow it out.
6. Inspect the overall condition of the unit. Make sure there are no fuel or oil
leaks or damaged parts. If any leaks or damaged parts are detected DO NOT
start the pressure washer until it is xed.
7. Connect the high-pressure hose to the pump and the gun wand assembly to
the other end of the hose.
8. Connect the garden hose to the pump.
8.1 Ensure the inlet lter on the pump is present, intact, and clean before
connecting the garden hose.
WATER SUPPLY MUST BE SUFFICIENT TO SUPPLY THE PUMP
ADEQUATELY.
Every pressure washer has a Gallons Per Minute (GPM)/ Liters Per Minute (LPM)
rating that must be adhered to. If the pump does not get enough water, it will
cavitate (starve for water). This will cause internal damage and pending failure.
To measure your water source GPM/ LPM, you will need a container that you
know the exact size such as a 5-gallon/20-Liter bucket. When you’re ready, start
lling it from your water source while timing it for one minute. The amount of
water in the 5-gallon/20-liter bucket after one minute is the GPM/LPM rating.
The water source GPM/ LPM should exceed the GPM/ LPM rating of the machine
by one GPM/ LPM to account for any uctuations from the water source.
The water source should have 20 to 60 PSI/1.38 to 4.1 BAR pressure going into
the pump. Do not use a hose longer than 50ft/15m to the water source.
PRIME THE PUMP WITH WATER
Once all the hoses are connected, turn on your water supply and hold down the
spray gun’s trigger. Let water ow through it until all the air bubbles are worked
through, and there is a constant stream of water coming out the nozzle.
Insert the color spray nozzle that you plan to use. Make sure the nozzle is clean
with no damage or blockages.

6. Put engine switch to the ON position. On the Honda GX, Ariens, and Kohler
SH270 engines it will be switch on the side of the engine like the picture
below. The Kohler CH440 has the ON/OFF built into the fuel valve.
7. With one hand, squeeze the trigger of the spray gun, so the water is owing.
Brace the pressure washer with your foot. With the other hand, grip the recoil
handle and slowly pull it out until you feel resistance. Pull briskly on the recoil.
You may have to pull it several times before it starts running.
8. Once the engine has warmed up, disengage the choke by moving the choke
lever all the way RIGHT on all models except the HONDA GC where the
choke tab is pushed all the way IN. If it stalls, then it needs to get warmer
before the choke is turned o. Restart the engine, let it warm up, and then try
turning the choke o again.
Important Note: The pressure washer has been designed to run at full throttle.
If you lower the throttle then the load-to-power ratio between the engine and
pump will be incorrect. This will cause undue strain on the system while pressure
washing, causing parts to wear quicker.

ELECTRIC MOTORS WITH
AUTO STOP
-
START SYSTEM
If your electric pressure washer is equipped with an auto start/stop system, it will
completely turn off when the spray gun trigger is released. Both pump and motor
will be inactive even though it is plugged in and turned on. When the trigger is
squeezed, the system will detect this and turn on. There will be a time delay
between depressing/releasing the trigger and the machine turning on/off.
Always turn the machine off when it is not going to be used for a significant
period of time. Do not rely on the auto start/stop system because if it fails, it will
lead to pump and/or motor failures.
ELECTRIC MOTOR STOP PROCEDURE
1. Keep the spray gun trigger squeezed and pointing in a safe direction.
2. Turn the motor to the o position.
3. Keep trigger squeezed to make sure all the pressure is released and it is only
garden hose pressure.
4. Unplug machine (if applicable, some may be hard wired).
5. Disconnect and drain hoses.
ELECTRIC MOTOR START PROCEDURE
1. Review all the safety warnings at the beginning of the manual. Turn the motor
to the o position.
2. Follow all the pre-operation steps before starting.
3. Connect pressure washer to a power source that matches the unit’s
requirements. It is critically important to have the pressure washer connected
to the correct power source, including volt, amp, and circuit breaker capacity.
Using a wrong power source will prevent start up, or damage the motor
causing it to fail.
4. Hold the spray gun, point it in a safe direction and squeeze the trigger.
5. Locate the ON/OFF switch on the pressure washer. Brace yourself for
possible kickback from the spray wand, and turn machine on.
GENERAL PRESSURE WASHER OPERATION TECHNIQUES
1. Always follow safety practices as outlined.
2. Always begin spraying at a safe distance from the intended surface and move
closer until the desired cleaning eect can be observed.
3. Generally, do not use a 90° spray angle. Instead, it is usually more eective to
use a shallower angle so that the reecting spray can be directed in safe and
controlled direction.
4. Holding down the trigger, move the wand side-to-side to clean the surface.
Once you get a feel for how the cleaning performance behaves you will
naturally nd your rhythm.
5. Always be aware of what you are spraying and take greater care on fragile
surfaces such as wood or glass to prevent damage.
6. Always remember to squeeze the trigger once every 30 seconds to ush the
pump with cool water to prevent overheating.
7. If you have to stop washing for more than a few minutes, you should turn o
the machine.

CLEANING WITH DETERGENTS
HOW TO CONTROL PRESSURE
• The pressure washer is preset at the factory to deliver the optimum
performance for its set up.
• Do not adjust the unloader.
• Adjusting the unloader can lead to failures, including poor performance, engine
stalling, and breaking internal parts of the pump and unloader.
• The primary method of controlling pressure is by the distance between the
nozzle and the surface. Always start far away and slowly move closer to the
surface.
• The angle of spray to the surface will also inuence pressure. For example,
coming at the surface at a 90° angle will have more impact force than a
shallow angle.
• Pressure can also be controlled by the type of nozzle that is put into the tip.
The wider the spray, the less pressure directly impacting the surface.
• Pressure can also be decreased by using nozzles with a larger orice size.
• Be careful when cleaning any soft surface like wood or anything that can crack
or break apart, like glass or paint.
CLEANING WITH DETERGENTS
1. The black soaper nozzle must be installed on the spray gun wand. It is the
only nozzle that will draw soap through the pressure washer system.
2. The detergent being used must have thin viscosity (similar to water).
3a.For models without an onboard soap tank; ll a container with detergent and
place it next to the pressure washer. Connect the clear detergent suction tube
to the brass barb on the pressure washer pump, and put the end with the lter
into the detergent container.
3b.For models with an onboard soap tank; ll the soap tank with the detergent.
4. Turn on the pressure washer and spray the water. You will be able to see the
detergent moving through the suction tube. Once the detergent is spraying
out the nozzle, it will cause foam to appear.
5. When using detergent, spray the desired area and give it some time for the
soap to chemically breakdown the dirt chemically. Then, wash it o with water
before it dries. Do not let the detergent dry on the surface as it may result in
damage.
6. When you are nished using the detergent you must ush the detergent
injector system to prevent detergent residue from building up. To rinse, use
clean water (either in a separate container or in the onboard soap tank).
Spray for at least two minutes while drawing the clean water through the soap
system.

STORAGE
Improper storage of the pressure washer will lead to failures that are not covered
by warranty.In general, cover the pressure washer and store it in a clean and dry
location. Wipe off any dirt or water.
WATER – FREEZING WARNING
Leaving water in the pump and accessories can result in damage if the
water freezes. Water will expand when it turns to ice. The resulting force will
cause ruptures and crack brass fittings, valves, and seals requiring complete
replacements (not warrantable).
1. When the unit is not in use, drain all the hoses and spray gun assembly.
2. If the unit is going to be stored for a extended period, or if there is any chance
the pressure washer will be exposed to freezing temperatures, then plumbing/
RV anti-freeze must be cycled through the pumps water ways.
3. We recommend using Ariens Power Equipment Pump Saver Anti-Freeze. It
has a specially designed cap to thread right onto the garden hose tting of the
pump. (Part number 85.490.046, contact your local dealer).
4. To apply, rst ensure the engine and fuel valve are in the OFF position.
5. Thread the bottle onto the garden hose tting of the pump and open the valve
on the cap. Pull the recoil to cycle the anti-freeze solution through the pump.
It is recommended to squeeze the bottle to force the anti-freeze into the pump
if needed. Continue until it comes out of the high-pressure hose tting. At this
point, anti-freeze is protecting all the internal water chambers of the pump.
6. The best defense against freezing is to store the pressure washer in a warm
location that will not be exposed to freezing temperatures.
GASOLINE ENGINE FUEL SYSTEM WARNING
Gasoline degrades overtime and will leave solid residues if it dries out in your fuel
system. This will clog the fuel system and result in failure to start the machine
(not warrantable).
1. Fuel degrades quicker the more it is exposed to air, and the greater the
ethanol percentage blend.
2. Fuel stabilizer is strongly recommended to slow down the degradation
process of fuel. Best practice is to mix the fuel stabilizer in the fuel storage
container.
3. If the unit will not be used within 30 days, then drain all the fuel from the tank
and carburetor.
3.1 Use fuel stabilizer in the tank to mix with the fuel.
3.2 To drain the fuel, have a container ready to catch the fuel.
3.3 Use a wrench to loosen the bottom bolt of the carburetor and let all
the fuel pour into the container. Once it stops, tighten the bolt. The fuel
stabilizer that was put in the tank earlier will help prevent any residue fuel
from drying into a hard residue.
3.4 Open the fuel valve of the engine.
3.5 To prevent wasting fuel, you can use the drained fuel in any vehicle that
uses the same type of fuel.
3.6 When storing gasoline, always use an airtight jerry can and fuel stabilizer
for best results. Best practice is to store fuel for no more than a year
before using it.
BATTERY (IF EQUIPPED)
1. Disconnect battery if it will not be used for two weeks or more.
2. Keep battery in a cool, dry place at normal room temperatures.
3. Is not used for 6 months or more, then it may need to be recharged.
