3. Never tamper with safety devices. Check their proper operation  
regularly.  
• USE OF EXTENSION CORDS  
Make sure the extension cord is in good condition before using. Always  
use the proper size extension cords with the tool – that is, proper wire  
size for various lengths of cord and heavy enough to carry the current  
the tool will draw. Use of an undersized cord will cause a drop in line  
voltage resulting in loss of power and overheating. For proper size  
cords see chart below.  
4. Keep mower free of grass, leaves, or other debris build-up. Allow  
mower to cool before storing.  
5. If you strike a foreign object, release bail handle to turn mower off,  
wait for the blade to stop and remove the safety key and then  
inspect the mower. Repair, any damage, before starting and

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.  
4. Remove square metal blade spacer O-2, square plastic blade  
insulator O-3, and blade O-4 as shown in figure O. Examine blade  
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.  
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 BLADE SHARPENING  
into small pieces and distribute them back into the lawn. Under normal  
conditions, the mulched grass will biodegrade quickly to provide  
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A  
nutrients to the lawn.  
DULL BLADE DOES NOT CUT GRASS CLEANLY OR MULCH  
PROPERLY.  
Please review the following recommendations for optimum mulching  
performance.  
WEAR PROPER EYE PROTECTION WHILE REMOVING,  
SHARPENING, AND INSTALLING BLADE. ENSURE THAT SAFETY  
KEY IS REMOVED.  
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.  
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.  
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.  
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:  
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.  
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.  
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.  
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.  
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

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.  
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.  
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.  
-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.  
BATTERY SERVICE AND INSTALLATION  
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.  
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.  
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.  
THE RBRC™ SEAL (Battery Recycling)  
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.  
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  
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  
perform short cutting tasks, but we don’t recommend this be done  
frequently. The battery and mower perform much better if charged  
fully.
