For best results, pump oil designed specifically for pressure washers
is recommended, as these contain a rust inhibitor and an anti-foaming
agent. If this oil is not available, an SAE 30W non-detergent oil may
be used.

7. Do not overreach or stand on unstable support. Keep good
footing and balance at all times.

8. Follow the maintenance instructions specified in the manual.

9. This product is provided with a Ground Fault Circuit Interrupter
built into the power cord plug. If replacement of the plug or
cord is needed, use only identical replacement parts.

10. Do not touch plug or outlet with wet hands.

11. Avoid accidental starts. Move switch on unit to OFF position
before connecting or disconnecting cord to electrical outlets.

16. The narrow pin point stream is very powerful. It is not
recommended for use on painted surfaces, wood surfaces or
items attached with an adhesive backing.

17. Keep operating area clear of all persons and ani mals.

18. Always use both hands when operating pressure washer to
maintain complete control of the wand.

19. Do not touch nozzle or water spray while operating. Never
place hands in front of nozzle.

20. Wear safety goggles while operating. Wear protective clothing
and footwear to protect against accidental spraying.

21. Disconnect power plug from the outlet when not in use and
prior to the detaching of the high pressure hose.

22. Never tie knots or kink the high pressure hose as da mage
could result. Inspect the high-pressure hose regularly. Replace
the hose immediately if it is damaged, worn or shows any signs
of cracks, bubbles, pinholes, or other leakage. Never grasp a
high-pressure hose that is leaking or damaged.

23. Do not operate or store this product in temperatures below
40 °F (4 °C). Freeze damage is not covered by the warranty.

24. Carefully observe all chemical instructions and warnings before
using. Use only approved pressure washer cleaners. Do not
use bleach, chlorine, or any cleaners containing acids. Always
follow manufacturer’s label recommendations for proper use
of cleaners. Always protect eyes, skin and respiratory system
from cleaners.

25. The pressure washer should not be used in areas where gas
vapors may be present. An electric spark could cause an
explosion or fire.

26. To minimize the amount of water getting into the pressure
washer, the unit should be placed as far as possible from the
cleaning site during operation.

27. To prevent accidental discharge, the spray gun should be
secured by locking the trigger when not in use.

28. To allow free air circulation, the pressure washer should NOT
be covered during operation.

29. Never touch, grasp or attempt to cover a pinhole or similar
water leak on the high-pressure hose. The stream of water IS
under high pressure and WILL penetrate skin.

30. Use only hoses and accessories rated for pressure higher
than your pressure washer's psi. Never use with any other
manufacturer’s accessories or components.

31. Never defeat the safety fea tures of this product.

MOTOR OVERLOAD

The electric motor in this pressure washer is equipped with an
overload protection device which will automatically shut off the motor
in the event the motor draws excessive current or overheats. The
device will automatically reset itself and resume normal operation after
a short period of time.

GROUNDING INSTRUCTIONS

This product must be grounded. If it should malfunction or breakdown,
grounding provides a path of least resistance for 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

5

&OHMJTI

plug must be plugged into an appropriate outlet that is properly
installed and grounded in accordance with all local codes and
ordinances.

WARNING: Improper connection of the equipment-grounding

conductor can result in a risk of electrocution. Check with a qualified
electrician or service person 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 installed by a qualified electrician. Do
not use any type of adaptor with this product.

GROUND-FAULT CIRCUIT INTERRUPTER PROTECTION

This pressure washer is provided with a Ground-Fault Circuit­Interrupter (GFCI) built into the plug of the power supply cord. This
device provides additional protection from the risk of electric shock.
Should replacement of the plug or cord become necessary, use only
identical replacement parts that include GFCI protection.

1PXFS 4VQQMZ "OE &MFDUSJDBM *OGP

GROUND-FAULT CIRCUIT INTERRUPTER PROTECTION

The pressure washer is factory-equipped with an electrical cord and
a Ground Fault Circuit Interrupter (GFCI) power plug. This cord should
only be connected to an electrical outlet installed in accordance with
local safety regulations.

NOTE: The power supply must be 120 V, 60 Hz and a minimum
15 amp dedicated circuit.

A. Inspect cord before using. Do not use if cord is damaged.
B. Keep all connections dry and off the ground.
C. Do not touch plug with wet hands.
D. The pressure washer is provided with a ground fault circuit

interrupter built into the power plug.

If replacement of the plug or cord is needed, use only identical
replacement parts. Contact customer service for proper replacement
parts.

WARNING: Test GFCI before each use. DO NOT use pressure

washer if test below fails.

GFCI Test Procedures:

1. Plug GFCI into power receptacle.

N

M

Indicator light should illuminate.

2. Press test button (M). Light should turn
off.

3. Press reset button (N) for use. Indicator
light should illuminate.

Do not use if above test fails.
NOTE: The GFCI must be reset each time

the pressure washer is connected to an
electrical outlet. Reset by simply pushing the
reset button on the GFCI power plug.

EXTENSION CORDS

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 not in use”. Use only extension
cords having an electrical rating not less than the rating of the product.
Do not use damaged extension cords. Examine extension cord before
using and replace if damaged. Do not abuse extension cord and do
not yank on any cord to disconnect.

Keep cord away from heat and sharp edges. Always disconnect the
extension cord from the receptacle before disconnecting the product
from the extension cord.

When using an extension cord, observe the specification below:

NOTE: The high-pressure pump was filled with oil at the factory.
Always check oil level before using (refer to Maintenance for more
information).

WARNING: Risk of bursting.

Use a tire pressure gauge to check the
tires pressure before each use and while inflating tires; see the tire sidewall
for the correct tire pressure.

NOTE: Air tanks, compressors and similar equipment used to inflate

tires can fill small tires similar to these very rapidly. Adjust pressure
regulator on air supply to no more than the rating of the tire pressure.
Add air in small increments and frequently use the tire gauge to
prevent over inflation.

OPERATION

1SFTTVSF "EKVTUNFOUT 'JH 

The pressure setting is preset at the factory to achieve op ti mum
pressure and cleaning. To lower the pres sure, follow these instructions.

1. Back away from the sur face to be cleaned. The further away you

are, the less the pressure will be on the surface to be cleaned.

2. Change to the 40˚ nozzle (white). This nozzle delivers a less

powerful stream of water and a wider spray pattern. Refer to
Spray Wand Nozzles.

3. Water pressure can be varied by turning the pressure adjusting

knob (L) clockwise to increase pressure and counterclockwise to
decrease pressure.

NOTICE: DO NOT attempt to increase pump pressure. A higher
pressure setting than the factory set pressure may damage pump.
