Black & Decker 90514757 Lawn Mower User Manual


 
YOUR LAWN LOOKING BEAUTIFUL
1. Lawns should first be mowed in the spring when the grass is
about 2 1/2 to 3 inches high. Mowing too early restricts the grass
root systems which renew themselves every spring. New grass
should be clipped when it is about 2 1/2 inches high.
2. 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 and thus making it more difficult for your lawn to reach
water in the soil.
3. Lawn care experts say that excessively close cutting is
responsible for much of the difficulty experienced on many lawns.
The depth and strength of the roots of grass are almost exactly
proportional to its growth. Grasses of mature lawns often are
seriously injured when mowed shorter than 1 1/2 inches, and a
height of 1 1/2 to 2 inches is preferred on large lawns.
4. 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 sensitive new
cut area of the grass will not be exposed to intense sunlight.
5. 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 susceptibility to turf
diseases. If the grass tips are bruised it causes a brownish colour
and gives your lawn an unhealthy appearance. A dull blade may
also pull up young seedlings.
6. Try to mow your lawn at the same (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.
7. If your lawn has grown too long, (a vacation, for example, may
interrupt your cutting schedule) mow at a cutting height one or two
positions higher than normal. A second pass at “normal” 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.
8. During the spring and fall, (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 circuit breaker to trip, which stops the motor.
9. Three good ideas 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.
10. 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 brown and appear ugly. This method
also preserves your battery charge, ensuring you get the most
from your Black & Decker Cordless Power Mower.
11. During the spring and fall seasons when the grass is longer and
thicker, you can use your mower without it being fully recharged.
(i.e. green charge indication light is on). This will enable you to
7
immediately afterward as follows: (1) Release switch lever to turn
mower off and remove safety key. (2) Wipe all exposed parts with a
damp cloth.

MOWER IN AN ATTEMPT TO CLEAN IT.
Do not store the tool on or adjacent to fertilizers or chemicals. Such
storage can cause rapid corrosion.

BATTERY
SERVICE
AND INSTALLATION
When service or repair is required, it is recommended that you take
your mower to an authorized Black & Decker Service Center.
When servicing or replacing batteries, please note:
• At the end of normal service life, both batteries should be replaced
at the same time. Mixing fresh and discharged batteries
could increase internal cell pressure and cause battery rupture.
• When inserting batteries into this product, the proper polarity or
direction must be observed. Reverse insertion of the batteries
can result in leakage or explosion.
THE RBRC™ SEAL (Battery Recycling)
The RBRC™ (Rechargeable Battery Recycling
Corporation) Seal on the lead acid battery (or battery
pack) indicates that the costs to recycle the battery (or
battery pack) at the end of its useful life have already
been paid by Black & Decker. In some areas, it is illegal to
place spent lead acid batteries in the trash or municipal
solid waste stream and the RBRC program provides an
environmentally conscious alternative.
RBRC in cooperation with Black & Decker and other battery users,
has established programs in the United States and Canada to
facilitate the collection of spent lead acid batteries. Help protect our
environment and conserve natural resources by returning the lead
acid battery to an authorized Black & Decker service center or to your
local retailer for recycling. You may also contact your local recycling
center for information on where to drop off the spent battery, or call
1-800-544-6986
