fingers, squeeze upward on the finger
grip and hold.
4. While holding the finger grip up you
can raise or lower the cutting height.
The mulcher has eight blade height
adjustment positions. Refer to the
scale and pointer (see Figure 4) at the
front of the mower. The pointer will
give you the height setting for cutting
your lawn. This setting can be a
reference for the next time you want to
cut your lawn at the same height.
When you have the mulcher at the
height you would like, simply release
the finger grip to lock the height adjust.
Note: To ensure that the deck is securely
locked in one of the eight positions,
press down on the palm rest after
releasing the finger grip.
Your mower is equipped with a special
switch. To operate the switch, insert your
finger into the opening (A) in figure 5 and
push the lever out so that you can grab it
with your other hand. Pull the lever back
to turn the unit on and hold it against the
mower handle to keep it running. To turn
the mower off, just release the lever. The
spring loaded "SNAP ACTION" lever will
quickly turn the mower off.
CAUTION: NEVER ATTEMPT TO
OVERRIDE THE OPERATION OF THIS
& Rear Door
This safety shield (Figure 6) is designed
to minimize the throwing of stones or
other objects by the mower blade
backward from under the mower deck.
The shield, along with the rear door
minimize the possibility of accidental foot
contact with the blade. DO NOT operate
mower without the safety shield and rear
door in place.
WARNING: For your own safety DO NOT
use this mower without either the
grasscatcher or mulch insert in operating
WARNING: Do not operate the
lawnmower if the rear door is not under
spring tension. Take your lawnmower to
the nearest service center or depot for
1. 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 blades.
2. Place most of the extension cord close
to the electrical outlet, out of the path
of the mower (Figure 7). CAUTION:
Do not plug extension cord into
receptacle outlet while standing in
water or when hands are wet.
3. Begin mowing in the area closest to
the outlet and mow in a back and forth
manner (Figure 7). Note that cord is
kept on cut portion of lawn.
Other Mowing Tips
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 switch to turn mower "OFF"
when crossing any graveled area
(stones can be thrown by the blade).
3. Set mower at highest cutting height
when mowing in rough ground or in tall
4. From time to time turn off mower and
wait for the blade to come to a
complete stop. Then unplug the power
cord 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. If a grass catcher is used
during the fast growing season, the
grass may tend to clog up at the
discharge opening. Turn the switch
"OFF" and disconnect the power cord
plug. 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. Clean often in wet,
5. If mower should start to vibrate
abnormally, turn mower "OFF" and
unplug power cord. Check immediately
for cause. Vibration is a warning of
trouble. Do not operate mower until a
service check has been made.
6. ALWAYS TURN THE SWITCH OFF
AND UNPLUG THE MOWER WHEN
LEAVING IT UNATTENDED EVEN
FOR A SHORT PERIOD OF TIME.
Your new mower is designed to re-cut the
grass clippings many times and reduce
them in size so that, as they fall into the
lawn, they will disperse into the grass and
not be noticed. Also, the mulched grass
will biodegrade quickly to provide
nutrients to the lawn.
Your mower was shipped with the Mulch
Insert installed from Black & Decker.

Mulching Mowing Tips
For best performance, keep the mower
housing free of built-up grass and trash.
Clean after each use. See CLEANING in
the maintenance section of this manual.
Avoid cutting the lawn when it is wet. Wet
grass tends to form clumps and they
interfere with the mulching action. The
best time to mow your lawn is in the early
afternoon. At this time the grass is dried
and the newly cut area will not be
exposed to the direct sun. For best
results, adjust the lawnmower cutting
height so that the lawnmower cuts off only
the top one third of the grass blades. If
the lawn is overgrown it will be necessary
to increase the cutting height to reduce
the pushing effect and reduce overloading
the motor. For extremely heavy mulching
make narrower cuts and mow slowly.
Certain types of grass and grass
conditions may require that an area be
