MOWING TIPS

NOTE: ALWAYS INSPECT AREA WHERE MOWER IS TO BE USED
AND REMOVE ALL STONES, STICKS, WIRE, BONES AND OTHER
DEBRIS WHICH MIGHT BE THROWN BY THE ROTATING BLADE.

1. 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 good footing.

2. Release bail handle to turn mower “OFF” when crossing any

gravel area (stones can be thrown by the blade).

3. Set mower at highest cutting height when mowing in rough ground

or in tall weeds. Removing too much grass at one time can cause
circuit breaker to trip, which stops mower. Refer to troubleshooting
guide.

4. If a grass catcher is used during the fast growing season, the grass

may tend to clog up at the discharge opening. Release bail handle
to turn mower off and remove the safety key. Remove the catcher
and shake the grass down to the back end of the bag. Also clean
out any grass or debris which may be packed around the discharge
opening. Replace the grass catcher.

5. If mower should start to vibrate abnormally, release bail handle to

turn mower off and remove safety key. Check immediately for
cause. Vibration is a warning of trouble. Do not operate mower until
a service check has been made. Refer to troubleshooting guide in
manual.

6. ALWAYS RELEASE BAIL HANDLE TO TURN MOWER OFF AND

REMOVE 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:

1. Slow down in areas where the grass is especially long or thick.

2. When mulching, avoid cutting more than 1-1/2 inches off the length
at any one time.

3. Avoid mowing when the grass is wet from rain or dew-soaked.

4. Cut your lawn frequently, especially during high growth periods.

NOTE: IT IS RECOMMENDED THAT YOUR MOWER BE
RECHARGED AFTER USE. FREQUENT CHARGING WILL NOT
HARM YOUR BATTERY, AND WILL ENSURE THAT THE BATTERY
IS FULLY CHARGED AND READY FOR ITS NEXT USE.

MULCHING MOWING TIPS

Your mower was shipped from Black & Decker with the mulch insert
installed.
While mulching, your new mower is designed to cut the grass clippings
into small pieces and distribute them back into the lawn. Under normal
conditions, the mulched grass will biodegrade quickly to provide
nutrients to the lawn.

Please review the following recommendations for optimum mulching
performance.

1. Avoid mowing when the grass is wet from rain or dew. Wet grass
may form clumps which interfere with the mulching action and
reduce run-time. The best time to mow grass is in the late afternoon
when the grass is dry and the newly cut area will not be exposed to
direct sunlight.

2. For best mulching performance, set the cutting height to remove
about one third of the grass blade length, ideally no more than

1-1/2 in. at one time. If the lawn is overgrown, it may be necessary
to increase the cut height to reduce the pushing effort and prevent
overloading the motor. For extremely heavy mulching, it is advisable
to first cut at a high cut height setting, and then re-cut to the final
cut height. Otherwise, make narrower cuts and mow slowly.

3. For best performance, keep the mower housing free of built-up
grass. From time to time release bail handle to turn mower off and
wait for the blade to come to a complete stop. Then remove the
safety key and turn mower on its side. Using an object such as a
stick, wipe out any accumulation of grass in the blade area. Be
careful of the sharp edges of the blade. Clean often in wet, spring
grass, and always after every use.

4. Certain types of grass or grass conditions may require that an area
be mulched a second time to fully disperse the grass throughout the
lawn. If cutting a second time, it is advisable to cut perpendicular
(across) the first cut pattern. DO NOT CHANGE CUT PATTERN IN
ANY WAY THAT WOULD CAUSE MOWING DOWN A HILL.

5. Change your cutting pattern from week to week. This will help
prevent matting of the lawn.

MAINTENANCE

IMPORTANT: To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment (including brush inspection and
replacement) should be performed by BLACK & DECKER Service
Centers or other qualified service organizations, always using
Black & Decker replacement parts. When servicing use ONLY
IDENTICAL REPLACEMENT PARTS.

insulator for damage and replace if necessary.

5. When replacing sharpened or new blade on shoulder of fan O-5,
make sure the “GRASS SIDE” on the blade will be facing the
ground when the mower is returned to its normal upright position.
After installing blade O-4, place blade insulator O-3 on blade such
that the raised lips on one side engage the edges of the blade.
Then install the blade spacer O-2 so that it sits inside the raised lips
on the other side of the blade insulator. Be sure to align the flats in
the hole of the blade spacer with the flats of the shaft, rotating the
blade and blade insulator together as necessary. Position piece of
wood P-1 to keep blade from turning as shown in figure P. Install
flange nut with the flange against the blade spacer and securely
tighten.

BLADE SHARPENING

KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A
DULL BLADE DOES NOT CUT GRASS CLEANLY OR MULCH
PROPERLY.

WEAR PROPER EYE PROTECTION WHILE REMOVING,
SHARPENING, AND INSTALLING BLADE. ENSURE THAT SAFETY
KEY IS REMOVED.

Sharpening the blade twice during a mowing season is usually
sufficient under normal circumstances. Sand causes the blade to dull
quickly. If your lawn has sandy soil, more frequent sharpening may be
required.

REPLACE BENT OR DAMAGED BLADE IMMEDIATELY.

WHEN SHARPENING THE BLADE:

1. Make sure blade remains balanced.

2. Sharpen blade at the original cutting angle.

3. Sharpen cutting edges on both ends of blade, removing equal
amounts of material from both ends.

TO SHARPEN BLADE IN A VISE:

1. Be sure the bail handle is released, the blade has stopped and the
safety key removed before removing the blade.

2. Remove blade from mower. See instructions for removing and
installing blade.

3. Secure blade L-1 in a vise L-2.

4. Wear proper eye protection and gloves and be careful not to cut
yourself.

5. Carefully file the cutting edges of the blade with a fine tooth file L-3
or sharpening stone, maintaining the original cutting edge.

6. Check balance of blade. See instructions for blade balancing.

7. Replace blade on mower and tighten securely.

BLADE BALANCING

Check balance of blade by placing center hole in blade M-1 over a nail
or round shank screwdriver M-2, clamped horizontally in a vise M-3. If
either end of the blade rotates downward, file that end. Blade is
properly balanced when neither end drops.

LUBRICA

TION

No lubrication is necessary. Do not oil the wheels. They have plastic
bearing surfaces which require no lubrication.

CLEANING

RELEASE BAIL HANDLE TO TURN MOWER OFF, LET THE BLADE
COME TO A STOP AND THEN REMOVE SAFETY KEY. USE ONLY
MILD SOAP AND A DAMP CLOTH TO CLEAN THE MOWER. CLEAN
OUT ANY CLIPPINGS WHICH MAY HAVE ACCUMULATED ON THE
UNDERSIDE OF THE DECK. AFTER SEVERAL USES, CHECK ALL
EXPOSED FASTENERS FOR TIGHTNESS.

HERE ARE SOME HELPFUL HINTS TO GET THE MOST FROM
YOUR BLACK & DECKER CORDLESS MOWER...AND KEEP 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.

PREVENTING CORROSION

Fertilizers and other garden chemicals contain agents which greatly
accelerate the corrosion of metals. If you mow in areas where
fertilizers or chemicals have been used, the mower should be cleaned
immediately afterward as follows: (1) Release bail handle to turn
mower off and remove safety key. (2) Wipe all exposed parts with a
damp cloth.

CAUTION: DO NOT POUR OR SPRAY WATER ON THE

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.

TRANSPORTING AND ST

ORAGE

DANGER: Rotating blade can cause serious injury. Release bail

handle to turn mower off and remove the safety key before lifting,
transporting or storing the mower. Store in a dry place.

OFF-SEASON STORAGE

1. In warmer climates to ensure optimal performance, it is
recommended that the battery be maintained on constant charge.

2. The mower may be stored with the charger disconnected if all of
the following conditions are met.

-the mower is fully charged before storing.

-the average temperature of the storage location is below
10°C (50°F)

-Storage duration is less than 6 months.

TTERY 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

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
perform short cutting tasks, but we don’t recommend this be done
frequently. The battery and mower perform much better if charged
fully.
