During the spring and autumn, or after an interruption to 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
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.
Always mow grass so that clippings are discharged onto cut
lawn. This will keep your lawn looking fresh by avoiding 'cut
grass' build-up which will eventually turn brown and appear
ugly. This method also preserves your battery charge,
making sure that you get the most from your Black & Decker
cordless power mower.
During the spring and autumn seasons when the grass is
longer and thicker, you can use your mower without the
battery being fully charged (ie the green charge indication
light is on). This will enable you to perform short cutting
tasks, however we don't recommend that this is done
frequently. The battery and mower perform much better
when fully charged.
