The powerful spray from your pressure washer is capable of causing damage to surfaces such as: wood, glass,
automobile paint, auto striping and trim, and delicate objects such as flowers and shrubs. Before spraying, check
the item to be cleaned to assure yourself that it is strong enough to resist damage from the force of the spray.
Avoid the use of the concentrated spray stream except for very strong surfaces like concrete and steel.
•Operating unit with the water supply shut-off will result in equipment damage. Operating the pressure
washer with water supply shut-off will void your warranty.
•
You should never run your pressure washer for more than 2 minutes without pulling the trigger. Pulling
the trigger allows cool water to enter the pump and maintains a normal operating temperature.
Read Owner’s Manual. Do not operate equipment until you have read Operation Manual for Safety,
Operation, and Maintenance Instructions.
D
amage caused by incorrect operation will not be covered
under warranty.
HAZARD WHAT CAN HAPPEN HOW TO PREVENT IT
Contact with hot surfaces, such as
engine’s exhaust components, could
result in serious burns.
During operation, touch only the
control surfaces of the pressure washer.
Keep children away from the pressure
washer at all times. They may not be
able to recognize the hazards of this
product.
Fuel or oil can leak or spill and could
result in fire or breathing hazard,
serious injury or death. Fuel or oil
leaks will damage carpet, paint or
other surfaces in vehicles or
trailers.
If pressure washer is equipped with
a fuel shut-off valve, turn the valve
to the off position before
transporting to avoid fuel leaks. If
pressure washer is not equipped with a
fuel shut-off valve, drain the fuel from
tank before transporting. Only

Assembly:
Unpacking Pressure Washer
•Set carton on a rigid, flat surface. Remove all loose parts and packing. Leave pressure washer in
carton.
•Using a box cutter carefully open the carton completely by cutting the four corners, allowing the sides to
lay flat. Leave pressure washer on carton while installing wheels and rubber feet.
Assembling the Wheels
•Fit the axles into the axle ports as shown,
•Secure the wheels to the axles with nyloc nut and washer.
NOTE: Do not over tighten the nuts; the wheels must be able to rotate freely.
Assembling the Rubber Feet
•Fit the rubber feet to the legs as shown with nuts and washers
provided.
Assembling the Gun/ Hose Hook
•Fit the hooks into the position shown and
secure using the washers and nuts on the bracket.

9
Preparing Pressure Pump:
The pressure pump has a shipping plug inserted into the opening for the pump breather plug.
Failure to remove shipping plug and replace it with the breather plug will
cause permanent damage and void warranty.
1. Remove the shipping plug, using a 17mm
open-end spanner(Discard shipping plug)
2. Remove pump breather plug from parts bag and
insert it into pressure pump.
3. Tighten pump breather plug securely by hand. Do not use a spanner or socket to tighten
4. Check sight glass to ensure pump oil is full, (half way up the sight glass).
5. If low, add oil to pump.
Recommended oil types:
•
Use SAE 10W/30 or 15W/40 Non detergent oil, SF, SG,SH, SJ, or higher.

10
Adding Oil to the Engine:
Engine oil is a major factor affecting engine performance and service life.
Non-detergent and 2-stroke engine oils will damage the engine and are not
recommended.
Place the Pressure Washer on a level surface.
1. Remove the oil filler cap and wipe the dipstick clean.
2. Check the oil level by inserting the dipstick into the filler neck without screwing it in.
3. If the level is low, add the recommended oil to the upper mark on the dipstick.
•Remove the oil bung/dipstick and fill the sump through the oil-filling hole. At the time of checking the oil
level, it is necessary only to lightly insert the dipstick. Do not screw the bung in to take the
measurement.
Never attempt to add oil to the engine while it is running. Hot oil may
splash on your face or hands causing serious injury.
Use 4-stroke oil, or equivalent high detergent, premium quality motor oil certified to meet or exceed U.S.
automobile manufacturer’s requirements for Service Classification SG, SF/CC, CD. Motor oils classified SG,
SF/CC, CD will show this designation on the container.
Recommended oil types:
•
For operation in Hot climates +10˚C to 40˚C use SAE 30 - API grade CC or CD
•
For cooler climates operation -10˚C to 30˚C use 10W30 - API grade CC or CD
Oil Alert System
The oil alert system is designed to prevent engine damage caused by an insufficient amount of oil in the
crankcase. Before the oil level in the crankcase can fall below a safe limit, the oil alert system will automatically
shut down the engine (the engine switch will remain in the ON position). The oil alert system shuts down the
engine and the engine will not start. If this occurs, first check engine oil.

11
Refueling Recommendations:
1. Refill the tank if the fuel level is low. Do not fill above the shoulder of the fuel strainer.
2. Avoid the generator stopping by running out of fuel, power variations will occur.
•
Gasoline is extremely flammable and is explosive under certain conditions.
•Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames
or sparks in the area where the engine is refueled or where gasoline is stored.
•Do not overfill the fuel tank (there should be no fuel in the filler neck). After refueling,
make sure the tank cap is closed properly and securely. Be careful not to spill fuel
when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the
area is dry before starting the engine.
•Avoid repeated or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.
Fuel type
Only use regular unleaded fuel. The fuel should be fresh, filtered cleanly and care taken not to let any dust or
water enter the fuel tank. Otherwise the filters and carburetor may be blocked or damaged.
Use gasoline with a pump octane rating of 86 or higher. We
recommend unleaded gasoline because it produces fewer engine
and spark plug deposits and extends exhaust system life.
Never use stale or contaminated gasoline or oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear light “spark knock” or “pinging” (metallic
rapping noise) while operating under heavy loads. This is no cause
for concern.
If spark knock or pinging occurs at a steady engine speed, under
normal load, change brands of gasoline. If spark knock or pinging
persists, see an authorized generator dealer.
Oxygenated Fuels
Some gasoline’s are blended with alcohol or an ether compound to increase the octane. These types of gasoline
are collectively referred to as oxygenated fuels. Some areas use oxygenated fuels to help meet clean air
standards. If you use an oxygenated fuel, be sure its pump octane rating is 86 or higher.
Ethanol (ethyl or grain alcohol)
Gasoline containing more than 10% ethanol by volume may cause starting or performance problems. Gasoline
containing ethanol may be marketed under the name “Gasohol”.
UPPER FUEL LEVER

12
Methanol (methyl or wood alcohol)
Gasoline containing methanol must contain co-solvents and corrosion inhibitors to protect the fuel system.
Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems and
may damage metal, rubber and plastic parts of your fuel system.
MTBE (methyl tertiary butyl ether)
You may use gasoline containing up to 15% MTBE by volume. Before using an oxygenated fuel, try to confirm the
fuel’s contents. Some states (provinces in Canada) require this information to be posted on the pump. If you
notice any undesirable operating symptoms, switch to a conventional unleaded gasoline. Fuel system damage or
performance problems resulting from the use of an oxygenated fuel are not our responsibility and are not covered
under warranty.
Oxygenated fuels can damage paint and plastic. Be careful not to spill fuel
when filling your fuel tank. Damage caused by spilled fuel is not covered
under warranty.
Running the engine with persistent spark knock or pinging can cause
engine damage. Running the engine with persistent spark knock or pinging
is misuse, and the Distributor’s Limited Warranty does not cover parts
damaged by misuse.
High Altitude Operation
•At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will
decrease, and fuel consumption will increase.
•High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor
and readjusting the pilot screw. If you always operate the engine at altitudes higher than 5000 feet (1500
meters) above sea level, have an authorized pressure washer dealer perform this carburetor modification.
•Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 1000
foot (300 meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
If a engine jetted for high altitude is used at a lower altitude, the lean air fuel
mixture will reduce performance and may over-heat and seriously damage
the engine.

BEFORE USE
Attaching High Pressure Hose to Spray Gun
•Pull slip ring on female quick-disconnect fitting of high
pressure hose back.
•Insert male quick-disconnect fitting on spray gun into female
fitting on high pressure hose.
•Release slip ring on female quick-disconnect and twist.
Listen for “click” to ensure both quick-disconnects are
coupled.
•Pull high pressure hose and spray gun in opposite directions
to ensure they do not separate.
Connecting Lance to Spray Gun
•Thread lance on to spray gun.
Connect Hose and Water Supply to Pump
•Attach high pressure hose to the high pressure outlet on pump
as per attaching High pressure hose to spray gun. Be sure to
pull on hose to be sure of tight connection.
•Before connecting garden hose to water inlet, inspect the inlet
screen. Clean screen if it contains debris or have it replaced
if damaged. DO NOT run pressure washer if inlet screen is
damaged.
•Run water through your garden hose for 30 seconds to clean
out debris before connecting.
IMPORTANT:
DO NOT siphon standing water for the water supply.
Water supply must be at 20psi, failure to do so will cause the
pump to run dry and damage will occur voiding warranty.
Use cold water only (less then 50 Degrees Celsius).
•Connect the garden hose (not to exceed 16 meters in length
and with the ID no less then 13mm) to the water inlet. Tighten
by hand.
•Turn ON the water, squeeze the trigger to purge the pump
system of air and impurities.
NOTICE
DO NOT attempt to crank or start engine, before it has been
properly serviced and had the recommended oil added.
-
There MUST be at least 3meters of unrestricted garden
hose between the pressure washer inlet and any device,
such as a vacuum breaker or check valve.
-
Damage to equipment resulting from failure to follow this
instruction will void warranty.

14
Getting Started:
Risk of eye injury.
Spray can splash back or propel objects.
- Always wear safety goggles when using this equipment or in
vicinity of where equipment is in use.
- Before starting the pressure washer, be sure you are wearing
adequate safety goggles.
- Never substitute safety glasses for safety goggles.
PRE START CHECKLIST
•Once you reach this point ensure you have done the following:
•All safety instructions read and understood
•All hose connections are tightened and hoses free of kinks
•Adequate amounts of lubrication and fuel have been added to
the engine & pump drive, breath plug fitted to pump.
•Water source connected and turned on; Note: cold water only
•All operation instructions read and understood
* P
ump oiled at factory – Replace transport plug with breather.
Preparation before starting:
•Add SAE 30 oil (SAE 10W30 multigrade for cold climates) to the engine (1100ml)
Note: There will be a residual amount of oil in the engine from factory testing
•Check the engine has an adequate fuel supply (unleaded, regular gasoline)
•Make sure that the work area has sufficient ventilation
•Ensure the ignition cable is secured to the spark plug
•Ensure water supply is turned on
1. Turn the fuel cock to the on position
2. Move the engine switch to the “on” position
3. Move the choke lever to the on position
ON
OFF
TO START:
4. Pull the trigger gun lever, to prevent pressure build up within the pump while starting. For safety reasons
ensure the nozzle is removed whenever starting the unit. Note * Failure to open the trigger valve while
starting, may overload the recoil starter causing damage to the mechanism.
5. Engage the recoil starter by pulling the rope handle out 25 to 50mm (1 to 2”).
6. Then deliver a short sharp pull to crank the engine over. In general most units will
fire and start on choke after two or three pulls. Do not let rope “snap back” against
starter.
7. Reduce choke as the engine warms up. The choke should be completely off after 2 or 3 minutes.

15
SHUT OFF PROCEDURE:
1. Release spray gun trigger and let engine idle for two minutes
2. Move the engine stop switch to the “stop” position. The engine will stop immediately.
3. Turn water supply off.
4. Turn Fuel Tap off.
5. Always point spray gun in safe direction, pull trigger to release retained high water pressure
before undoing hose and trigger from pump.
The spray gun and hose traps high water pressure even when engine is stopped and water
disconnected.
HIGH PRESSURE OPERATION:
Never pull the hose to move the unit. This could damage hose and/or pump inlet.
Never allow pump to run with water hose turned off or kinked. Shutting off the water supply to the pump
while it is operating may cause serious pump damage.
Do not let hoses contact HOT engine muffler during or immediately after use, as this will damage the
hose.
Interchangeable Nozzles :
•Pull back the quick connect lock ring, firmly insert the desired nozzle and then release the lock ring.
•Make sure the spray nozzle is properly locked in place with its quick coupler, if the collar is not
(Forward) in the locking position, the nozzle may become a dangerous projectile. The O-ring from your
quick coupler socket may also be blown out of place.
To prevent damage to your surface to be cleaned always start with lowest pressure
nozzle size (white) and continue changing to the higher nozzle size until the best
work result is achieved.
Pressure washer produces fluid pressures and velocity high enough to penetrate
human and animal flesh which could result in series injury or amputation. DO NOT
point pressure washer in direction of people or animals. High velocity fluid spray
can cause objects to break, propelling particles at high speeds.

16
(Red) (Yellow) (Green) (White)
Explanation:
0° nozzle setting – A pinpoint stream. This nozzle stream is very powerful and covers a very small area of
cleaning. Only to be used on surfaces that can withstand this high pressure (metal or concrete).
15°to 25°nozzle setting – Used for less powerful stream which can cover a wider area. This nozzle setting is
also very powerful and should only be used on surfaces that can withstand this high pressure.
40°nozzle setting – Used for the least powerful stream and covers a wide area of cleaning. This nozzle setting
should be used for most general cleaning jobs.
Pressure Adjustment:
The maximum working pressure is pre-set at the factory and can not be overridden. By turning the pressure
adjustment knob anti-clockwise you can reduce both the pressure and water volume being supplied from the
pump.
Low Pressure Detergent Operation:
The Black Tip – will lower the pressure and allow chemical to be drawn through
the downstream chemical injector.
•Change the high pressure nozzle for the Detergent (Black) Nozzle.
(Be sure the quick coupler is fully engaged before pulling the trigger)
•The chemical injector will only work when this (black) nozzle is used.
•Push the ¼” clear plastic hose to the inlet barb of the chemical
injector located near the high pressure hose connection (item 8,
page 2).
•Insert the loose end of the detergent pick up hose into the
desired chemical.
Be sure to flush the injection system with clean water after use.
•Place the chemical injector hose in a bucket of clean water and
operate for one minute.

Rinsing Pressure:
Pressure Washer Rinsing
•Remove black spray tip from lance.
•Select & install desired high pressure spray tip following
instructions in High Pressure Operation section of this manual.
•Keep spray gun a safe distance from area you plan to spray.
•Increase or decreases spray pressure by turning the Pressure
Adjustment Knob, clockwise to increase or counter clockwise to
decrease. Use lower pressure to wash items such as a car or
boat. Use higher pressure to strip paint and degrease
driveways.
•Apply a high pressure spray to a small area and then check
surface for damage. If no damage is found, it is okay to continue rinsing.
•Start at top of area to be rinsed, working down with same overlapping strokes as used for cleaning.
Thermal Relief Valve:
During normal operation, the cold water from your water supply
passes through the inside of the pressure pump allowing the
pump to maintain a normal operating temperature. When you
let go of the trigger, the pump enters by-pass mode and
re-circulates water within the pump.
If the unit is left in the by-pass mode for more than two (2)
minutes, the water temperature may rise to a dangerous level
causing cavitation and possible damage to internal components
of the pump. As a safe guard against damage from
overheating, pumps are equipped with a thermal relief valve.
This safety valve will open when the internal water temperature
becomes too high, once cool the valve will close again
automatically.
Do not attempt to run hot water into the pump or allow your unit to operate in the by-pass mode for long
periods of time (2 minutes max), as overheating of the pump will cause component damage.

18
MAINTENANCE:
WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER
PRESSURE, MOVING PARTS, OR FIRE WHICH MAY RESULT IN SERIOUS INJURY OR
EVEN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, LET THE
ENGINE COOL DOWN COMPLETELY AND RELEASE ALL WATER PRESSURE. THE
ENGINE CONTAINS FLAMMABLE FUEL. DO NOT SMOKE OR WORK NEAR OPEN
FLAMES WHILE PERFORMING MAINTENANCE.
Nozzle cleaning:
If the nozzle becomes clogged with foreign material, such as sand, flow will
cease or become restricted. Clean the nozzle immediately using the nozzle
cleaner supplied and the following instructions:
•Shut off the pressure washer and turn off the water supply.
•Pull trigger on gun handle to relieve any built up water pressure.
•Remove the nozzle from the lance assembly.
•Turn the nozzle end up.
•The nozzle hole is approximately 1mm in diameter, it is the smallest
hole in the system, even a single grain of sand can block the nozzle.
•Clean the nozzle using the nozzle cleaner provided or wire of
appropriate size. Insert into the nozzle end and push. Remember that
any obstruction will have been lodged in place under very high pressure
and may require an equal amount of force in the opposite direction to
dislodge it.
•It is important that you see the obstruction come out of the lance,
otherwise the nozzle may block again.
•Reconnect nozzle to lance and turn on water supply.
•Recommence operation.
Water Inlet Screen Cleaning:
The water inlet filter screen should be checked periodically and cleaned whenever necessary.
1. Remove the water inlet hose connection to expose the inlet filter.
2. Remove the filter screen and flush with clean water from both sides.
3. Replace the cleaned filter screen into the water inlet connector.
4. Tighten securely (clockwise)
Do not operate the pressure washer without a water inlet filter installed.
Check High Pressure Hose:
The high pressure hose can develop leaks from wear, kinking or abuse. Inspect the hose each time before using
it. Check for cuts, leaks, abrasions or bulging of cover, damage or movement of couplings. If any of these
conditions exist, replace the hose immediately.
The high pressure stream of water that this equipment produces can cut through skin and its
underlying tissues, leading to serious injury and possible amputation.
•
Never repair high pressure hose. Replace it.
•Replacement hose rating MUST exceed maximum pressure rating of unit.

19
PUMP OIL MAINTENANCE:
CHANGING PUMP OIL
Change oil after first 50 hours of operation and then every 200 hours or 3 months, which ever occurs first.
Note: When changing pump oil, use only high quality non-detergent SAE30 oil. Use no special additives.
CHANGE PUMP OIL AS FOLLOWS:
•Clean area around brass oil drain plug at bottom of pump.
•Remove oil drain plug. Drain oil completely into approved container.
•When oil has completely drained, install oil drain plug and tighten firmly.
•Clean area around pump breather plug. Remove breather and fill pump with 600ml of recommended oil.
Make sure it shows halfway on sight glass, add more if necessary.
•Wipe up any spilled oil.
Used motor oil may cause skin cancer if repeatedly left in contact with
the skin for prolonged periods. Although this is unlikely unless you
handle used oil on a daily basis, it is still advisable to thoroughly wash
your hands with soap and water as soon as possible after handling
used oil.
Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a
sealed container to your local service station or recycling center for reclamation. Do not throw it in the trash or
pour it on the ground.
LONG-TERM STORAGE:
Before you store the pressure washer, make sure you do the following:
1. Remove fuel from engine or add fuel stabilizer, such as “Sta-Bil” to the gasoline to prevent gumming,
and operate unit normally for five minutes.
2. If adding stabilizer, connect water supply and high pressure hose to pump.
3. Ensure water supply is turned on, start pressure washer and depress gun trigger to avoid running the
unit in the “by-pass mode.”
5. Disconnect spark plug wire and remove spark plug. Pour one teaspoon of engine oil into the spark plug
hole. Place a rag over spark plug hole and pull rope slowly several times to lubricate cylinder, replace
spark plug and lead.
6. Protect the high pressure hose, gun and wand from damage (such as being stepped on or run over).
TO PREVENT INTERNAL CORROSION OR FREEZING:
Items needed:
100cm piece of garden hose or equivalent and antifreeze (approximately 200 mℓ.)
1. To winterize the pressure pump, prevent the engine from starting by disconnecting the spark plug wire
from the engine and remove high pressure hose from the pump. Add automotive antifreeze corrosion
inhibitor through the water inlet, place the garden hose direct into the anti freeze container. Pull engine
rope several times until antifreeze comes out of high pressure outlet connector. You have now
displaced the water in the pump with corrosion inhibitor.
2. Remove all water from high pressure hose, gun, and wand. To do so, disassemble high pressure hose
from gun. Drain all water from hose. Hold gun/wand assembly in a vertical position with the nozzle
pointing down, and pull gun trigger to remove any water.

20
ENGINE MAINTENANCE:
WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER
PRESSURE, MOVING PARTS, OR FIRE WHICH MAY RESULT IN DEATH. BEFORE
PERFORMING ANY MAINTENANCE OR REPAIR, LET THE ENGINE COOL DOWN
COMPLETELY AND RELEASE ALL WATER PRESSURE. THE ENGINE CONTAINS
FLAMMABLE FUEL. DO NOT SMOKE OR WORK NEAR OPEN FLAMES WHILE
PERFORMING MAINTENANCE.
1. If the engine can not be started or starting is difficult, first check whether the
fuel system has fresh fuel and adequate oil level.
2. Secondly check the spark plug. Remove the spark plug cap, take out the
spark plug, clean any carbon deposits and adjust the plug gap to specified gap
and reassemble.
3. As well you should ensure that the inlet of the air filter and exhaust outlet
are clean. Maintain a clean air filter. Inspect regularly and clean or replace as
necessary.
