2) Electrical Safety
a ) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed orgrounded.
b ) Do not expose pressure washers to rain or wet
conditions. Water entering a pressure washer will
increase the risk of electricshock.
3) Personal Safety
a ) Stay alert, watch what you are doing and use
common sense when operating a pressure
washer. Do not use a pressure washer while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention
while operating pressure washers may result in serious
personalinjury.
b ) Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non‑skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personalinjuries.
c ) Prevent unintentional starting. Ensure the switch
is in the off‑position before connecting to the
battery pack, picking up or carrying the tool.
Carrying pressure washers with your finger on the

tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of asecond.
4) Pressure Washer Use and Care
a ) Do not use the pressure washer if the switch does
not turn it on and off. Any pressure washer that
cannot be controlled with the switch is dangerous and
must berepaired.
b ) Remove the battery pack from the pressure
washer before making any adjustments,
changing accessories, or storing pressure
washers. Such preventive safety measures reduce the
risk of starting the pressure washeraccidentally.

vehicularcharger.
• Foreign materials of a conductive nature, such as, but
not limited to, grinding dust, metal chips, steel wool,
aluminum foil or any buildup of metallic particles
should be kept away from the charger cavities and
ventilation slots.
• Always unplug the charger from the power supply
when there is no battery pack in thecavity.
Charging a Battery (Fig.C)
1. Plug the charger into an appropriate outlet.
2. Insert and fully seat battery pack. The red charging light
will continuously blink whilecharging.
3. Charging is complete when the red charging light
remains continuously ON. Battery pack can be left in
charger or removed. Some chargers require the battery
pack release button to be pressed forremoval.
WARNING: Only charge batteries in air temperature
over 40° F (4.5° C) and below 105° F (+40.5°C).
4. Charger will not charge a faulty battery pack, which
may be indicated by the light staying OFF. Take charger
and battery pack to an authorized service center if light
staysOFF.
NOTE: Refer to label near charging light on charger
for blinkpatterns. Older chargers may have additional
information and/or may not have a yellow indicatorlight.
Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot
or too cold, it automatically starts a Hot/Cold Pack Delay,
suspending charging until the battery pack has reached an
appropriate temperature. The charger then automatically
switches to the pack charging mode. This feature ensures
maximum battery packlife.
A cold battery pack may charge at a slower rate than a warm
batterypack.
The hot/cold pack delay will be indicated by the red light
continuing to blink but with the yellow light continuously
ON. Once the battery pack has reached an appropriate
temperature, the yellow light will turn OFF and the charger
will resume the chargingprocedure.
DCB118 and DCB1112 Chargers
The DCB118 and DCB1112 chargers are equipped with
an internal fan designed to cool the battery pack. The fan
will turn on automatically when the battery pack needs to
becooled.

overheat and burst, resulting in personal injury, property
damage, fire, electric shock orelectrocution.
• Do not expose the charger to rain orsnow.
• Do not allow water or any liquid to entercharger.
• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.
• Make sure that the cord is located so that it will not
be stepped on, tripped over or otherwise subjected to
damage orstress.
• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in
risk of fire, electric shock orelectrocution.
• When operating a charger outdoors, always provide
a dry location and use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electricshock.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the heavier the cord and
thus the greater its capacity. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size
to use depending on total length of all extension cords
plugged together, and nameplate ampere rating. If in
doubt, use the next heaviergauge.

unprotected skin, eyes, or with any pets or animals.
Serious injury willoccur.
CAUTION: Before operation:
• Connect the water supply to the power cleaner.
For instructions on connecting the water supply
to the power cleaner, please refer to Attaching
Garden or Suction Hose under Assembly
andAdjustments.
• Connect the pressure spray wand, soap bottle,
or other attachment. For instructions on
connecting the pressure spray wand, please
refer to To Attach the Spray Wand, Soap
Bottle or other Attachment under Assembly
andAdjustments.
Pressure Washing
Preparing Surface for Cleaning
• Remove objects from the area which could create
ahazard.
• Ensure that all doors and windows are closed tight. Protect
all plants and trees in the adjacent area with a drop cloth
ensuring that they will not be harmed by anyoverspray.
• Pre‑rinse cleaning area with freshwater.
• Use only detergents formulated for pressurewashers.
• Always test detergent in an inconspicuous area beforeuse.
Speed Selector (Fig.A, K)
This power cleaner gives you the choice to operate at a lower
pressure for more delicate jobs, or accelerate the power
cleaner speed for high‑performancecleaning.
To accelerate, pull the speed selector19 back toward the
main handle1 into the "HI" position. This mode is best for
applications that need higherPSI.
For low pressure, push the speed selector forward toward
the spray wand8 into the "LO" position. This mode is best
for larger projects that require more time tocomplete.
NOTE: When in "HI" mode, runtime will be decreased as
compared to when pressure cleaner is in "LO"mode.
1. To start the power cleaner, disengage the trigger
lock‑off4 and squeeze the trigger6.
NOTE: The best angle for spraying water against a
cleaning surface is 45°. Spraying head on tends to cause
dirt particles to embed in the surface. When working on
vertical surfaces, it is best to apply detergent starting at
the bottom and working upwards which will prevent the
detergent from sliding down and causingstreaks.
2. To stop the power cleaner, release thetrigger.
NOTE: Excessive pump pressure may be the result of a
clogged nozzle or brass coupling. Always turn off the power
cleaner and remove the battery before attempting to unclog
a nozzle or brasscoupler.
WARNING: Never draw from water that contains
chemicals. Only draw from fresh watersources.
