tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
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.
Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain
long hair. Loose clothes, jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of
the power tool in unexpected situations.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
Maintain power tools and accessories. Check

jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain
long hair. Loose clothes, jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of
the power tool in unexpected situations.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
Maintain power tools and accessories. Check
for misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations, as
well as the specific potential hazards related to this
power tool. Following this rule will reduce the risk of
electric shock, fire, or serious injury.

to comply with ANSI Z87.1 when assembling parts,
operating the tool, or performing maintenance.
Following this rule will reduce the risk of serious
personal injury.
This product is suitable for indoor and outdoor use.
Do not use battery-operated appliance in rain.
Check to make sure the brush accessory is installed
correctly prior to use.
Do not force the scrubber into tight spaces during
use.
Do not touch rotating accessories when product is
in use.
Battery tools do not have to be plugged into an
electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards
when not using your battery tool or when changing
accessories. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
WARNING:
Do not allow familiarity with this product to make
you careless. Remember that a careless fraction of
a second is sufficient to inflict serious injury.
WARNING:
Do not use this product if it is not completely
assembled or if any parts appear to be missing or
damaged. Use of a product that is not properly and
completely assembled or with damaged or missing
parts could result in serious personal injury.
Always close the battery cover and lock the tab
before use. Do not expose the battery pack to rain
or wet conditions. Water entering a power tool will
increase the risk of electric shock and fire.

WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
Avoid body contact with earthed or grounded

refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain
long hair. Loose clothes, jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of
the power tool in unexpected situations.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
Maintain power tools and accessories. Check
for misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations, as
well as the specific potential hazards related to this
power tool. Following this rule will reduce the risk of
electric shock, fire, or serious injury.
Always wear eye protection with side shields marked
to comply with ANSI Z87.1 when assembling parts,
operating the tool, or performing maintenance.
Following this rule will reduce the risk of serious
personal injury.
This product is suitable for indoor and outdoor use.
Do not use battery-operated appliance in rain.
Check to make sure the brush accessory is installed
correctly prior to use.
Do not force the scrubber into tight spaces during
use.
Do not touch rotating accessories when product is
in use.
Battery tools do not have to be plugged into an
electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards
when not using your battery tool or when changing
accessories. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
WARNING:
Do not allow familiarity with this product to make
you careless. Remember that a careless fraction of
a second is sufficient to inflict serious injury.
WARNING:
Do not use this product if it is not completely
assembled or if any parts appear to be missing or
damaged. Use of a product that is not properly and
completely assembled or with damaged or missing
parts could result in serious personal injury.

tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
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.
Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain
long hair. Loose clothes, jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of
the power tool in unexpected situations.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
Maintain power tools and accessories. Check

jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
Do not wear loose clothing or jewelry. Contain
long hair. Loose clothes, jewelry, or long hair can be
drawn into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of
the power tool in unexpected situations.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
Maintain power tools and accessories. Check
for misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations, as
well as the specific potential hazards related to this
power tool. Following this rule will reduce the risk of
electric shock, fire, or serious injury.
Always wear eye protection with side shields marked
to comply with ANSI Z87.1 when assembling parts,
operating the tool, or performing maintenance.
Following this rule will reduce the risk of serious
personal injury.
This product is suitable for indoor and outdoor use.
Do not use battery-operated appliance in rain.
Check to make sure the brush accessory is installed
correctly prior to use.
Do not force the scrubber into tight spaces during
use.
Do not touch rotating accessories when product is
in use.
Battery tools do not have to be plugged into an
electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards
when not using your battery tool or when changing
accessories. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
WARNING:
Do not allow familiarity with this product to make
you careless. Remember that a careless fraction of
a second is sufficient to inflict serious injury.
WARNING:
Do not use this product if it is not completely
assembled or if any parts appear to be missing or
damaged. Use of a product that is not properly and
completely assembled or with damaged or missing
parts could result in serious personal injury.
Always close the battery cover and lock the tab
before use. Do not expose the battery pack to rain
or wet conditions. Water entering a power tool will
increase the risk of electric shock and fire.
Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces
the risk of electric shock.

Do not crush, drop or damage battery pack. Do not
use a battery pack or charger that has been dropped

subject to explosion. Properly dispose of a dropped
or damaged battery immediately.
Batteries can explode in the presence of a source
of ignition, such as a pilot light. To reduce the risk of
serious personal injury, never use any cordless product
in the presence of open flame. An exploded battery can
propel debris and chemicals. If exposed, flush with
water immediately.
Under extreme usage or temperature conditions,
battery leakage may occur. If liquid comes in
contact with your skin, wash immediately with soap
and water. If liquid gets into your eyes, flush them
with clean water for at least 10 minutes, then seek
immediate medical attention. Following this rule will
reduce the risk of serious personal injury.
