Mowing (fig. M1 & M2)
We recommend to use your mower as outlined in this section
in order to achieve optimum results and to reduce the risk of
cutting the mains cable.
Place the bulk of the mains cable on the lawn, close to the
u
starting point (position 1 in fig. M1).
Switch the appliance on as described above.
u
Proceed as shown in fig. M1
u
Move from position 1 to position 2.
u
Turn right and proceed towards position 3.
u
Turn left and move towards position 4.
u
Repeat the above procedure as required.
u
Warning! Do not work towards the cable as shown in fig. M2.
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 sufficient
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:
Make sure blade remains balanced.
u
Sharpen blade at the original cutting angle.
u
Sharpen cutting edges on both ends of blade, removing
u
equal amounts of material from both ends.
To sharpen blade in a vice (fig.N)
Be sure the blade has stopped and the mower is
u
unplugged before removing the blade.
Remove blade from mower. See instructions for removing
u
and installing blade.
Secure blade (10) in a vice (12).
u
Wear proper eye protection and gloves and be careful not
u
to cut yourself. Carefully file the cutting edges of the blade
with a fine tooth file (13) or sharpening stone, maintaining
12
(Original instructions)
the angle of the original cutting edge. Check balance of
blade. See instructions for blade balancing.
Replace blade on mower and tighten securely.
u
Blade balancing (fig. 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, file 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:
Switch off and unplug the appliance/tool.
u
Or run the battery down completely if it is integral and then
u
switch off.
Unplug the charger before cleaning it. Your charger does
u
not require any maintenance apart from regular cleaning.
Regularly clean the ventilation slots in your tool/appliance
u
and charger using a soft brush or dry cloth.
Regularly clean the motor housing using a damp cloth. Do
u
not use any abrasive or solvent-based cleaner.
Regularly use a blunt scraper to remove grass and dirt
u
from the underneath of the guard.
