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

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: Ifyou 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.
