SAFETY INSTRUCTIONS
20.Watch your balance and footing while
using your pressure washer. Surfaces
become slippery when wet and are extra
slippery when using a detergent or cleaner.
21.
Never operate the pressure washer in
bare feet, sandals, or open-toed shoes.
22.When using the pressure washer near
children, make sure they are closely
supervised by an adult to avoid injury.
Never let a child use the pressure washer.
23.Keep fingers, hands, feet and any part
of your body clear of the stream of high
pressure water. The powerful spray can
cause blindness or blast holes in the skin.
It can break a window if you are too close
when you pull the trigger on the spray gun.
24.
Always wear eye protection to prevent
injury to eyes when operating the pressure
washer.
25.To avoid mishaps or injury, ALWAYS use
the trigger safety lock when not using the
pressure washer even if only stopping
briefly.
26.The pressure washer is equipped with a
Ground Fault Circuit Interrupter (GFCI)
which greatly reduces the chance of
electric shock while the unit is in use. If
replacement of the plug or cord is needed,
use only identical replacement parts.
27.Point the spray gun in a safe direction
when beginning a pressure washer
session.
28.Warning- NEVER spray directly at a
person, animal, electrical device or the unit
itself.
29.When first using the spray gun, hold
the spray gun and lance with two hands
when pulling the trigger (one hand to pull
the trigger and the other to stabilize the
gun assembly) until you get used to the
“kickback” from the spray gun.
30.When you press the power switch to turn
off the pressure washer, water pressure
may remain in the system. To discharge
the pressure, point thespray gun in a safe
direction and pull the trigger.
31.Never spray flammable liquids.
32.
Never use the pressure washer in areas
that contain combustible dust, liquids or
vapors.
33.Avoid contact of the pressure hose with
sharp objects and examine the hose
regularly. Replace if damaged. Due to
the high pressure involved, it cannot be
repaired if cut or damaged.
34.Only use detergent specifically formulated
for pressure washers and follow
instructions on the detergent’s label. Dish
or laundry soap is too thick and will clog
the nozzle of your foam cannon.
35.Protect eyes, lungs, and skin from
exposure to detergent.
36.Warning-If connection is made to a
potable water system, the system Should
be protected against backflow.
CAUTION: Store the pressure
washer indoors to prevent the water in the
unit from expanding under freezing
conditions. When the water freezes and
expands, your pressure washer will be
damaged and become inoperable. Or, if
storing outdoors, it is recommended you use
pump saver (not included) to protect pumps.
WARNING:This product can expose
you to chemicals including lead, DEHP, DINP,
which is known to the State of California to
cause cancer and or lead to birth defects. For
more information go to www.P65Warnings.
ca.gov.
37.
Never use hot water with your pressure
washer. It will overheat and damage the
high pressure pump.
38.
Never leave the pressure washer
unattended while it is powered “on”.
39.
Always turn the water supply on before
turning the pressure washer power to on.
Running the pump dry will cause damage
to the internal components.
40.
Never use a water supply to your pressure
washer that exceeds 150 PSI maximum.
41.
Never disconnect the high pressure
hose from the pressure washer while the
system is pressurized.
42.
Never permanently engage the trigger
mechanism on the spray gun.
43.
Never operate the pressure washer unless
all components are properly and securely
connected.
44.
Never allow the pressure washer pump
to run for more than one minute after you
have turned off the water supply. This can
cause the motor and pump to overheat
and fail.

SAFETY INSTRUCTIONS
45.
Never use lances or other parts that are
not compatible for this specific Masterforce
unit.
46.
Never use an extension power cord since
it defeats the effectiveness of the GFCI
and increases the chance of electrocuting
the operator.
47.Never spray any electrical outlet with your
pressure washer.
48.Inspect the power cord before using. Do
not use it if it is damaged
49.Stay alert - watch what you are doing.
KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE.
Ground Fault Circuit Interrupter Protection:
This pressure washer is provided with a
ground-fault circuit-interrupter (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.
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 plug must be plugged
into an appropriate outlet that is properly
installed and grounded in accordance with all
local codes and ordinances.
DANGER – Improper connection of the
equipment-grounding conductor can result in
a risk of electrocution. Check with a qualified
electrician or service personnel 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,
have a proper outlet installed by a qualified
electrician. Do not use any type of adaptor
with this product.

OPERATING INSTRUCTIONS
Operation Tips
• Note: Test the GFCI before each use:
1. Plug GFCI into power outlet. Indicator
should turn green to show that cord has
power.
2. Press test button, green indicator should
turn off to verify that GFCI cut off power to
the cord.
3. Press reset button – green indicator
should turn on to show that cord has
power again.
4. When GFCI is working properly, green
indicator will turn on when power is
applied. If green indicator turns off, it has
detected electric leakage and the GFCI
cut off power to the appliance.
• If you hear the motor run intermittently
when the trigger is not being squeezed,
that is normal. The pump is priming itself
so it is ready to operate when the trigger is
squeezed. Turn off the pressure washer if
not being used after five minutes.
• The o-rings on the bayonet end of the
nozzle should be cleaned regularly and
lubricated with non-water soluble grease
such as petroleum jelly (not included).
• Keep the nozzle cleaning wire for use
in unclogging the nozzle. If you lose the
cleaning wire, a straightened paper clip also
works.
How to Avoid Damaging Surfaces
• Damage to surfaces being cleaned occurs
because the impact force of the water
pressure exceeds the durability of the
surface. Bare wood can be penetrated, paint
can be peeled off, etc. You can vary the force
of your pressure washer by controlling:
1. The angle of the surface being cleaned.
2.The distance of the nozzle from the
surface being cleaned.
• Never use a narrow high pressure stream
of water on soft surfaces susceptible to
damage.
• Use the 25˚ angle quick connect nozzle
when cleaning windows. Be sure to place
the nozzle approximately 4 to 5 ft. away from
the window with the nozzle at 45° angle.
Squeeze the trigger and vary the spray
pattern and angle until optimum cleaning
efficiency is achieved.
Using Power Cord
• Remove the power cord from the unit by
swiveling the cord hook to the right or left.
The power cord then can be slid off to either
side of the pressure washer unit.
• Swivel cord hook back to center when ready
to wrap the cord back into place for storage.

CARE AND MAINTENANCE
Detergents
• Use detergents designed for pressure
washers. Hardware stores or home centers
also have pressure washer detergents for
different cleaning projects. The cleaning
solution should be the consistency of water
in order to prevent clogging your detergent
bottle and nozzle.
• This system applies detergent under
low pressure. The cleaning power of the
detergents is enhanced when applied with
low pressure and enough time is given to
break down dirt and grime. The combination
of low pressure and chemical action is very
effective and can be better than scrubbing if
applied properly. Always spray detergent on
a dry surface. Do not pre-soak area. Wetting
the surface first dilutes the detergent and
reduces its cleaning ability. Do not allow
detergent to dry on surface. On vertical
surfaces being cleaned, apply detergent
to lower surfaces and work your way up
to prevent detergent from causing streaks
in the dirt and grime. Rinse detergent by
pressure washing from bottom up for same
reason.
• If a stain is particularly tough, it may be
necessary to reapply the detergent and
use a bristled brush to scrub the stain.
Subsequent pressure washer after brushing
should successfully complete your cleaning
job.
Cleaning Garden Hose Adapter
• The screen inside the adapter should be
cleaned periodically. Remove it by dragging
a thumb over the screen with enough
pressure to pull the screen and washer out.
Rinse it with clean water and then place it
back in the adapter.
Cleaning Nozzles
• A clogged or partially clogged nozzle
can cause significant reduction of water
pressure coming out of the nozzle and/or
cause the unit to pulsate while spraying.
• Turn off the unit.
• Turn off the water supply to the unit.
• Relieve any pressure trapped in the hose by
squeezing the trigger 2 - 3 times, then lock
the spray gun by turning the dial to lock (“3”
and “9” position).
• Using the nozzle tip cleaner provided (or an
unfolded paper clip), insert the wire into the
nozzle hole and move back and forth until
debris is dislodged.
• Back flush water through the nozzles using
garden hose and highest pressure available
(either standard water nozzle or use your
thumb over the nozzle to create water
pressure for back flush).

Storage
• When your pressure washer session has
been completed, turn off the power switch.
Unplug the power cord from the outlet. Turn
off the water supply. Pull the trigger on the
spray gun 2-3 seconds to drain out the
excess water and to release any remaining
water pressure. Do not allow the pressure
washer to run with no water flowing through
it.
• Remove high pressure hose from spray
gun and unscrew the other end of the high
pressure hose from the pressure washer.
• Remove lance from the gun. Place the gun
and lance in the holster on the sides.
CARE AND MAINTENANCE
• The quick connect nozzles and rotary nozzle
are stored on the nozzle holder located on
both sides of machine.
•
DO NOT store the pressure washer where
it is exposed to freezing temperatures
unless you use an antifreeze designed
for pumps. Store the pressure washer
indoors to prevent the water in the unit
from expanding under freezing conditions.
When the water freezes and expands, your
pressure washer will be damaged and
become inoperable. Or, if storing outdoors,
it is recommended you use pump saver (not
included) to protect pumps.
• Make sure to discard any remaining
detergent from the tank. Residual chemical
will stick to the container which could
become contaminated, and can cause the
detergent injector to clog and not function
properly. Flush the tank and nozzle head with
clear water to prevent clogging.
• Wind the power cord around the L-shaped
hooks located on the top of the machine.
• The pressure hose is stored on the hose
hook located on the back of the handle.
