NOTE: The cut height range for your mower is

1-1/4” to 3-1/2”

WHEEL HEIGHT ADJUSTMENT (FIGURE 8)

1. BEFORE MAKING ANY ADJUSTMENTS, TURN OFF, UNPLUG MOWER AND

WAIT FOR BLADE TO STOP.

2. Your mower features the Black & Decker one touch wheel height adjustment

system. This system will adjust all four wheels at the same time.

3. To raise or lower the cutting height. See Figure 8. Rest the palm of your hand

on the palm rest and with your 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 8) 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.

INSTALLING MULCH INSERT (MULCHING)

1. UNPLUG MOWER, AND WAIT FOR BLADE TO COME TO A COMPLETE STOP.

2. Raise the rear discharge door and hold it up as shown in Figure 4A.

3 Slide the mulch insert into the discharge opening until it is firmly in contact with the deck.

OPERATING INSTRUCTIONS

NOTE: A lawnmower is a major appliance and should not be operated

simultaneously with other major appliances on the same house circuit.

Warning: Make sure that other persons and pets are at least 100 feet away.

Remove all stones, sticks, wire, bones,

and other debris which might be thrown

by the rotating blades

ATTACHING EXTENSION CORD TO MOWER (FIGURE 5)

DO NOT connect the extension cord to power source until you have finished

reading this manual and you are ready to start mowing.

1. The extension cord must be polarized and will only plug in one way, orient the

wide slot with the wide blade in the switch housing.

2. Loop the extension cord and push the loop up through the hole in the switch

housing.

3. Pull the extension cord on the side of the loop that is plugged into the switch

housing and remove all the slack in this section of the extension cord.

4. Place the loop over the strain relief tab on the switch housing and pull the

extension cord so the loop draws down around the strain relief tab as shown

in the detail. Double check to see that you did not loosen the extension cord.

SWITCH USE (FIGURE 6)

Your mower is equipped with a special switch. To operate the switch, insert your

finger into the opening (Figure 6) and push the lever out so that you can grasp 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.

EXTENSION CORD TO ELECTRICAL OUTLET (FIGURE 7)

1. Place most of the extension cord close to the electrical outlet, out of the path of

the mower. Attach extension cord to mower.

2. Start in direction where extension cord side of mower is closest to the outlet.

Begin mowing in the area closest to the outlet and mow in a back and forth

manner. Note the cord is kept on cut portion of lawn and out of the path of the

mower. (Figure 7)

3. Avoid mowing in circles as cord will be harder to manage.
