ENGLISH (Original instructions)
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.
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.
u
Mow across the face of slopes, never up-and-down.
Exercise extreme caution when changing direction on
slopes. Do not mow excessively steep slopes. Always
maintain a good footing.
u
Release the bail bar (3) to turn the lawnmower off when
crossing any gravel area as stones can be thrown by the
rotating blade.
u
Set the lawnmower at the highest cutting height when
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 bag (15) is used during the fast growing season,
the grass may tend to clog up at the discharge opening.
u
Release the bail bar (3) to turn the lawnmower off and
remove the safety key (1).
u
Remove the grass bag (15) and shake the grass to the
back of the bag.
u
Clean out any grass or debris which may be packed
around the discharge opening.
u
Refit the grass bag (15).
If the lawnmower starts to vibrate abnormally:
u
Release the bail bar (3) immediately to turn the
lawnmower off and remove the safety key (1) and the
battery pack (11).
u
Investigate the cause of the vibration. Vibration is a
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:
u
Slow down in areas where the grass is especially long or
thick.
u
When mulching, avoid cutting more than 38 mm of the
length at any one time.
u
Avoid mowing when the grass is wet.
u
Cut your lawn frequently, especially during periods of high
growth.
Note It is recommended that your lawnmower be recharged
after each use. Frequent charging will not harm the battery
and will make sure that the battery is fully charged.
Mulching mowing tips
When mulching, your lawnmower is designed to cut the grass
clippings into small pieces and distribute them back into the
lawn. Under normal conditions, the mulched grass will
bio-degrade quickly to provide nutrients to the lawn.
Recommendations for optimum mulching performance:
u
Avoid mowing when the grass is wet. Wet grass may form
clumps which interfere with the mulching action and
reduce run time. The best time to mow grass is in the
afternoon when the grass is dry and the newly cut area will
not be exposed to direct sunlight.
u
For best mulching performance, set the cutting height to
remove about one third of the grass length, ideally no
more than 38 mm at one time. If the lawn is overgrown, it
may be necessary to increase the cutting height to reduce
the pushing effort and to prevent overloading the motor.
u
For extremely heavy mulching, it is advisable to first cut at
a high cutting height setting, and then cut to the final
cutting height or make narrower cuts and mow slowly.
For best performance, keep the lawnmower housing free of
built-up grass:
u
Release the bail bar (3) to turn the lawnmower off and wait
for the blade to come to a complete stop.
u
Remove the safety key (1) and the battery pack (11) and
turn the lawnmower on its side.
u
Use a blunt scraper to remove the accumulation of grass
in the blade area. Be careful of the sharp edges of the
blade. Clean more often when cutting lush grass, and
always after every use.
