Vibration
The declared vibration emission values
stated in the technical data and the
declaration of conformity have been
measured in accordance with a standard
test method provided by EN60335 and
may be used for comparing one tool with
another. The declared vibration emission
value may also be used in a preliminary
assessment of exposure.
Warning! The vibration emission value
during actual use of the power tool can
differ from the declared value depending
on the ways in which the tool is used.
The vibration level may increase above
the level stated. When assessing
vibration exposure to determine safety
measures required by 2002/44/EC to
protect persons regularly using power
tools in employment, an estimation of
vibration exposure should consider, the
actual conditions of use and the way the
tool is used, including taking account of
all parts of the operating cycle such as
the times when the tool is switched off
and when it is running idle in addition to
the trigger time.
Do not operate the tool if the vibration
registers as abnormal.
Safety of others
uThis appliance is not intended for use
by persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience
and knowledge, unless they have
been given supervision or instruction
concerning use of the appliance by a
person responsible for their safety.
uChildren must be supervised to
ensure that they do not play with the
appliance.

10
ENGLISH (Original instructions)
uAfter striking a foreign object. Inspect
the appliance for damage and make
repairs as necessary.
Residual risks
Additional residual risks may arise when
using the tool which may not be included
in the enclosed safety warnings. These
risks can arise from misuse, prolonged
use etc. Even with the application of
the relevant safety regulations and the
implementation of safety devices, certain
residual risks can not be avoided. These
include:
uInjuries caused by touching any
moving parts.
uInjuries caused by touching any hot
parts.
uInjuries caused when changing any
parts or accessories.
uInjuries caused by prolonged use of
the appliance.
When using any appliance for
prolonged periods ensure you take
regular breaks.
uImpairment of hearing.
uHealth hazards caused by breathing
dust developed when using your
tool (example:- working with wood,
especially oak, beech and MDF.)
uIf operating the mower in a damp
location is unavoidable, use a residual
current device (RCD) with a tripping
current of not more than 30 mA.
Use of an RCD reduces the risk of
electric shock.
uNever pick up or carry an appliance
while the motor is running.

Blade sharpening
Note: The BEMW351 uses the BLACK+DECKER blade (Cat #
A6323). Keep blade sharp for best mower performance. A dull
blade does not cut grass cleanly. Use proper eye protection
while removing, sharpening, and installing blade. Sharpening
the blade twice during a mowing season is usually sufcient
under normal circumstances.
Sand causes the blade to dull quickly. If your lawn has sandy
soil, more frequent sharpening may be required.
Note: Replace bent or damaged blade immediately.
When sharpening the blade:
uMake sure blade remains balanced.
uSharpen blade at the original cutting angle.
uSharpen cutting edges on both ends of blade, removing
equal amounts of material from both ends.
To sharpen blade in a vice (g.N)
uBe sure the blade has stopped and the mower is
unplugged before removing the blade.
uRemove blade from mower. See instructions for removing
and installing blade.
uSecure blade (10) in a vice (12).
uWear proper eye protection and gloves and be careful not
to cut yourself. Carefully le the cutting edges of the blade
with a ne tooth le (13) or sharpening stone, maintaining
the angle of the original cutting edge. Check balance of
blade. See instructions for blade balancing.
uReplace blade on mower and tighten securely.
Blade balancing (g. O)
Check balance of the blade (10) by placing centre hole in
the blade over a nail or round shank screwdriver, clamped
horizontally in a vice. If either end of the blade rotates
downward, le along the sharp edge of that dropping end.
Blade is properly balanced when neither end drops.
Lubrication
No lubrication is necessary. Do not oil the wheels. They have
plastic bearing surfaces which require no lubrication.
Cleaning
Turn the mower off and let the blade come to a stop. Use only
mild soap and a damp cloth to clean the mower. Clean out any
clippings which may have accumulated on the underside of
the deck. After several uses, check all exposed fasteners for
tightness.
Preventing corrosion
Fertilizers and other garden chemicals contain agents which
greatly accelerate the corrosion of metals. If you mow in areas
where fertilizers or chemicals have been used, the mower
should be cleaned immediately afterward as follows:
Turn the mower off and unplug mower. Wipe all exposed parts
with a damp cloth.
Maintenance
Your BLACK+DECKER corded/cordless appliance/tool has
been designed to operate over a long period of time with a
minimum of maintenance. Continuous satisfactory operation
depends upon proper tool/appliance care and regular
cleaning.
Warning! Before performing any maintenance on corded/
cordless power tools:
uSwitch off and unplug the appliance/tool.
uOr run the battery down completely if it is integral and then
switch off.
uUnplug the charger before cleaning it. Your charger does
not require any maintenance apart from regular cleaning.
uRegularly clean the ventilation slots in your tool/appliance
and charger using a soft brush or dry cloth.
uRegularly clean the motor housing using a damp cloth. Do
not use any abrasive or solvent-based cleaner.
uRegularly use a blunt scraper to remove grass and dirt
from the underneath of the guard.
