Note When you turn off the self drive, for example at the
end of a row, it may become temporarily locked if you pull
backwards on the mower. Simply push ahead slightly and then
move the mower as required.
Note During cutting, at times it may be easier to manoeuver
around an object , such as a tree or plants, with the self drive
off. The mower can easily be used with the self drive off.
"ON-DEMAND" mulching (fig. N & O)
The lawnmower is equipped with an On-Demand feature that
allows the conversion of mulching to bagging or discharging
with the turn of a knob.:
Release the bail bar (3) to turn the lawnmower off, wait
u
until the blade stops and remove the safety key (1).
Discharge Mode:
Remove the grass catcher.
u
Ensure the rear discharge door rests firmly against the
u
deck.
Press and turn the On-Demand knob so that it is in-line
u
with the word "DISCHARGE" (fig N).
Note Your mower is now in rear discharge mode. The cut
grass will be deposited below the closed door exit onto the
lawn.
Bagging Mode:
Install the grass catcher.
u
Ensure the rear discharge door rests firmly against the top
u
of the grass catcher.
Press and turn the On-Demand knob so that it is in-line
u
with the word "BAG" (see figure N).
Note Your mower is now in Bagging mode. To change to rear
discharge mode at this point, just remove the grass catcher.
Mulching Mode:
To convert to mulch mode press and turn the On-Demand
u
knob so that it is in-line with the word "MULCH" (see figure
O). Your mower is now in mulch mode.
Note If it becomes difficult to rotate the On-Demand knob, it
may be necessary to clean out the deck chute.
Release the blade bail handle to turn mower off and wait
u
for the blade to come to a complete stop. Then remove
safety key and battery pack.
Hold the rear discharge door open, and clean out any
u
debris that may be in the deck chute. Also clean the deck
bottom as necessary.
Installing the grass bag (fig. P & Q)
Release the blade bail bar (3) to turn the lawnmower off,
u
wait until the blade stops and remove the safety key (1).
Open the spring-loaded rear discharge door (6) to the
u
vertical position and hold it in the open position.
(Original instructions)
Use the handle (29) on the grass bag (15) and install the
u
grass bag between the mower handles.
Position the grass bag hanger hooks on to the mower (fig
u
Q).
Release the rear discharge door (6).

Hints for optimum use
Lawns should first be mowed in the spring when the grass
is about 63 mm to 76 mm high. Mowing too early in the
season restricts the root systems of the grass which renew
themselves every spring. New grass should be mowed when it
is about 63 mm high.
Do not remove too much grass blade surface at one time,
never more than 1/3 of the leaf height during each cutting.
Cutting too close 'shocks' sensitive grass blades, resulting in
a shallow root system making it more difficult for your lawn to
reach water in the soil.
Mow your lawn when it is dry to avoid clumping of wet grass. If
you have a choice, late afternoon is the ideal time for mowing,
not only because the grass is dry, but also because the sensi-
tive new cut area of the grass will not be exposed to intense
sunlight.
Keep the mowing blade sharp for a nice clean cut. This
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
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 exam-
ple, 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 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.
