PRODUCT SAFETY
GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow all
instructions listed below may result in electric shock,
fire and/or serious injury.
Save all warnings and instructions for future
reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-
operated (cordless) power tool.
1 WORK AREA SAFETY
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2 ELECTRICAL SAFETY
a) 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.
b) 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.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) 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.
e) 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.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
3 PERSONAL SAFETY
a) Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use a power tool while you are
tired or under the influence of drugs, alcohol
or medication. A moment of inattention while
operating power tools may resultin serious
personal injury.
b) Use personal protective equipment. Always
wear eye protection. Protective equipment such
as 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 power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your finger on the switch or energising power tools
that have the switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away
from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
g) 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.
h) 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.
4 POWER TOOL USE AND CARE
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

20V Yard Sprayer WG829E W829E.X
g) Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe handling
and control of the tool in unexpected situations.
5 BATTERY TOOL USE AND CARE
a) Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.
b) Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c) When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
d) Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water. If
liquid contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
e) Do not use a battery pack or tool that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behaviour
resulting in fire, explosion or risk of injury.
f) Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
g) Follow all charging instructions and
do not charge the battery pack or tool
outside the temperaturerange specified
in the instructions. Charging improperly or at
temperatures outside the specified range may
damage the battery and increase the risk of fire.

VIBRATION INFORMATION
Vibration total values (triax vector sum) determined ac-
cording to EN 62841:
Vibration emission value:
ah<2.5 m/s2
Uncertainty K = 1.5m/s²
The declared vibration total value and the declared noise emission
value have been measured in accordance with a standard test
method and may be used for comparing one tool with another.
The declared vibration total value and the declared noise emission
value may also be used in a preliminary assessment of exposure.
WARNING The vibration and noise emissions during
actual use of the power tool can differ from the declared
value depending on the ways in which the tool is used especially
what kind of workpiece is processed dependant on the following
examples and other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained.
The use of the correct accessory for the tool and ensuring it is
sharp and in good condition.
The tightness of the grip on the handles and if any anti vibration
and noise accessories are used.
And the tool is being used as intended by its design and these
instructions.
This tool may cause hand-arm vibration syndrome if its use
is not adequately managed.
WARNING To be accurate, an estimation of exposure
level in the actual conditions of use should also take
account of all parts of the operating cycle such as the times when
the tool is switched off and when it is running idle but not actually
doing the job. This may significantly reduce the exposure level
over the total working period.
Helping to minimise your vibration and noise exposure risk.
Always use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions and keep
well lubricated (where appropriate).
If the tool is to be used regularly then invest in anti vibration and
noise accessories.
Plan your work schedule to spread any high vibration tool use
across a number of days.
