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 7)
Your mower is equipped with a special switch. To operate the switch,
insert your finger into the opening (Figure 7) 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.
WARNING: NEVER ATTEMPT TO OVERRIDE THE OPERATION
OF THIS SWITCH.

EXTENSION CORD TO ELECTRICAL OUTLET (FIGURE 8)
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 8)
3. Avoid mowing in circles as cord will be harder to manage.

WHEEL HEIGHT ADJUSTMENT (FIGURE 9)
1. BEFORE MAKING ANY ADJUSTMENTS, TURN OFF, WAIT FOR
BLADE TO STOP AND UNPLUG MOWER.
2. Your mower features the Black & Decker single lever wheel height
adjust system. This system will adjust all four wheels at the same
time. Mower adjusts from 1 to 3 1/2 in. (25.4mm - 88.9mm) with six
increments.
3. Place your left hand on the height adjust handle and your right hand
on the lower handle as shown in Figure 9.
4. Pull height adjust handle away from mower, and re-set in the
desired height adjust position. (See recommended cutting height by
grass type under OPERATING INSTRUCTIONS) Rotating the
height adjust towards the front of the mower lowers the cutting
height, and rotating towards the rear raises the cutting height.

MULCHING TIPS
In the mulching configuration your new mower is designed to re-cut
the grass clippings into short lengths.
These clippings, which are dispersed as you mow will biodegrade
quickly and provide nutrients for the lawn.
• Set mower at highest cutting height when mowing in rough ground or
in tall weeds.
• Do not cut the lawn when it is wet. Wet grass tends to form clumps
with the mulching action. The best time to cut your lawn is in the
afternoon.
• For best results, adjust the mower cutting height so that the mower
cuts off only the top third of the grass blades.
• If your lawn is overgrown it may be necessary to increase the cutting
height to reduce the pushing effect and prevent overloading the motor.
• For extremely heavy mulching make narrower cuts and mow slowly.
• Change your cutting pattern from week to week. Mow north to south
one week and east to west the next week. This will help prevent
matting and graining of the lawn.
