OPERATING INSTRUCTIONS
Mowing tips
Note: A sharp blade will greatly enhance the performance of the mower, especially when cutting
high grass. Be sure to check the blade and to sharpen it at least once per year, as described in
the Care and Maintenance section.
Verify that the lawn is free of stones, sticks, wires, and other objects that could damage the
blades or the motor. These objects could be accidentally thrown by the mower in any
direction, and could cause serious personal injury to the operator and to others. In order to
prevent electric shock, do not operate the mower in damp or wet conditions.
Do not mow in circles. Travel back and forth across the lawn.
When cutting thick grass, reduce walking speed in order to allow for a more effective cut and
a proper discharge 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 long during cool months, and
between 2 to 3-1/4 in. long during hot months. If there is growth, the lawn should be cut in
the fall.
Mulching tips
Note: Inspect the area where the mower is to be used and remove all stones, sticks, wires,
bones, and other debris that might be thrown by the rotating blade.
Release the bail lever to turn the mower OFF when crossing any graveled area (stones can
be thrown by the blade).
Set mower to the highest cutting height when mowing on uneven ground or in tall weeds.
For effective mulching, do not cut wet grass, because it tends to stick to the underside of
the deck, preventing proper mulching of grass clippings. New or thick grass may require a
narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing
has been delayed and the grass has been allowed to grow longer than 4 in. (10 cm), mow
the lawn twice in order to reduce the grass height to a maximum of 3-1/4 in. (8.3 cm).
Walk at a steady pace. Overlap the cutting rows. Do not let the grass get too tall. If the grass
gets too long, start at the highest cutting position and work down to the desired cutting height.
WARNING
If you strike a foreign object, stop the motor and remove the battery. Thoroughly inspect the mower
for any damage. Repair any damage before operating the mower. Excessive vibration of the
mower during operation is an indication of damage. Thoroughly inspect the mower and repair any
damage before operating the mower.
6. Emptying the grass catcher bag
Stop mower, allow blades to completely stop, and
remove the battery.
Lift the rear discharge cover.
Lift the grass catcher bag by its handle to remove from
mower.

catcher bag as described earlier in this manual.
