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.

Switch

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

SWITCH.

Safety Shield

& 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

position.

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

repair.

MOWING PROCEDURE

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

weed.

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,

spring grass.

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.

Mulching

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.

See section of manual for removing

mulch insert.

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
