StoppingtheMotorandBlade

WARNING: The blade continues to rotate for a

few seconds after the motor is shut off. If the motor

does not come to a stop when the motor/blade

control handle is released, contact an authorized

service dealer.

To stop the motor and blade from spinning:

Release the motor!blade control lever from its

position against the upper handle and the blade

and motor will quickly come to a stop.

NOTE: A high pitched noise may occur as the electric

motor decelerates and some sparking may occur also

at the same time. This is normal behavior when the

motor and blade is disengaged.

MowingYourLawn

NOTE: A sharp blade will greatly increase the

performance of the lawn mower, especially in

conditions of higher grass. Be sure to check the blade

and sharpen it at least once a year as outlined in the

Maintenance section.

Be sure that lawn is clear of stones, sticks, wires, or

other objects which could damage the lawn mower

or motor. Such objects could be accidentally thrown

by the mower in any direction and cause serious

personal injury to the operator and others.

To prevent electric shock, do not operate the

mower in damp or wet conditions.

Always start from the point closest to the power

source where the cord is connected. Never mow

around the lawn in circles; travel back and forth

across the lawn, starting from the point closest to

the outlet and then moving away from the outlet so

the cord lies in the cut portion of the lawn, out of the

way. See Figure 10.

Figure 10

Do not allow the extension cord to wrap around

trees, shrubs or other obstacles. When picking up

the extension cord, wind the cord in a series of

equal loops on each side of your hand to prevent

snarling.

When cutting heavy grass, reduce walking speed to

allow more effective cut and proper collection of the

clippings. For a healthy lawn, always cut off one-

third or less of the total length of the grass. The

average lawn should be approximately 1-1/2 to 2

inches during the cool season, and over 2 inches

during hot months. For a healthier and better

looking lawn, cut more often and after moderate

growth. The lawn should be cut in the fall season as

long as there is growth.

WARNING: If you strike a foreign object, stop

the motor, and unplug from the power supply

circuit. Thoroughly inspect the mower for any

damage, and repair the damage before restarting

and operating the mower. Excessive vibration of

the mower during operation is an indication of

damage. The unit should be promptly inspected

and repaired.

NOTE: For rough or uneven lawns, move the wheels to

a position which will give a higher cutting height.

WARNING: Always stop the motor and

disconnect from the power source before cleaning,

lubricating or performing any repairs or

maintenance on the lawn mower.

This mower has three cutting height positions as shown
