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” 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 switch lever 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.
PLEASE REFER TO DIAGRAMS (A, B, C...) AND ITEM NUMBERS
(1, 2, 3...) AS NOTED THROUGHOUT MANUAL. FOR EXAMPLE,

REMOVING
AND INST
ALLING BLADE
1. RELEASE SWITCH LEVER TO TURN MOWER OFF, WAIT FOR
THE BLADE TO STOP, AND REMOVE SAFETY KEY.
2. Cut a piece of 2x4 wood N-1 (about 2 feet long) to keep blade from
turning while removing flange nut.
3. Turn the mower on its side. Wear gloves and proper eye protection.
Be careful of sharp edges of blade. Position wood and remove
flange nut N-3 with 3/4” (19mm) wrench N-2 as shown in Figure N.
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.
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 switch lever 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.
LUBRICATION
No lubrication is necessary. Do not oil the wheels. They have plastic
bearing surfaces which require no lubrication.
CLEANING
RELEASE SWITCH LEVER 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.
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
