for mowing, not only because the grass is dry, but also
because the sensitive new cut area of the grass will not be
exposed to intense sunlight.
Keep the mowing blade sharp for a nice clean cut. This
u
improves the mower's performance and enhances the look
of your lawn. A dull blade shatters and bruises the tips of
the grass. This impairs the healthy growth of your lawn
and increases the susceptibility to turf diseases. If the
grass tips are bruised it causes a brownish colour which
gives your lawn an unhealthy appearance. A dull blade
may also pull up young grass seedlings.
Try to mow your lawn at a consistent cutting height. While
u
there are times when you should vary the cutting height
with the changing seasons, a consistent cutting height
produces a healthier, lovelier lawn with generally fewer
weeds. Mow more frequently during periods of fast growth.
Frequent cutting ensures that the lower, less attractive
portion of the grass will not show.
If your lawn has grown too long, during a vacation for
u
example, mow at a cutting height one or two positions
higher than normal. A second pass at your usual
cutting height a few days later will put your lawn back
on schedule.
Changing the cutting height is a simple matter with
BLACK+DECKER's One Touch Wheel Height Adjustment,
which simultaneously adjusts all four wheels at once.
During the spring and autumn, or after an interruption to
u
the cutting schedule, the grass will be longer and thicker. If
the motor continually slows down while cutting, try setting
the wheels for a higher cutting height. Excessive motor
loading can result in uneven cutting, quicker discharge of
the battery and can cause the motor to overload which
stops the motor.
There are three good ways to enhance your lawn's
u
appearance: Vary the mowing direction frequently; mow
horizontally on hillsides; (this is also a good safety
practice) and do not forget to overlap the mowing path on
each pass.
Mowing tips
Note: Always inspect the area where the lawnmower is to be
used and remove all stones, sticks, wire, bones and other
debris which could be thrown by the rotating blade.
Mow across the face of slopes, never up‑and‑down.
u
Exercise extreme caution when changing direction
on slopes. Do not mow excessively steep slopes. Always
maintain a good footing.
Release the bail bar (2) to turn the lawnmower off when
u
crossing any gravel area as stones can be thrown by the
rotating blade.
Set the lawnmower at the highest cutting height when
u
mowing in rough ground or in tall weeds. Removing too

much grass at one time may cause the motor to overload
which will stop the lawnmower. Refer to the
troubleshooting guide. If the grass box (9) is used during
the fast growing season, the grass may tend to clog up at
the discharge opening.
Release the bail bar (2) to turn the lawnmower off and
u
remove the safety key (1).
Remove the grass box (9) and shake the grass to the
u
back of the bag.
Clean out any grass or debris which may be packed
u
around the discharge opening.
Refit the grass box (9).
u
If the lawnmower starts to vibrate abnormally:
Release the bail bar (2) immediately to turn the
u
lawnmower off and remove the safety key (1) and the
battery pack (22).
Investigate the cause of the vibration. Vibration is a
u
warning. Do not operate the lawnmower until a service
check has been made. Refer to the troubleshooting guide
in the manual.
Note: Always release the bail bar to turn the lawnmower off
and remove the safety key when leaving it unattended even
for a short period of time.
The following suggestions will help you to obtain optimum
run‑time from your cordless mower:
Slow down in areas where the grass is especially long or
u
thick.
Avoid mowing when the grass is wet.
u
Cut your lawn frequently, especially during periods of high
u
growth.
