When changing the cutting height from an established
setting to a lower setting, the grass may appear ragged
or uneven until the grass adjusts to the new established
cutting height and regains its normal appearance.
•
When cutting grass over six inches (15 cm) tall, use a
conventional lawn mower first, then mow again with
the robotic lawn mower at the desired setting for the
best lawn appearance. If the grass is too long, the
robotic lawn mower may leave clumps on top of the
lawn or even plug and stall.
•
When mowing a large plot (greater than 2500 sq. ft.
(250 sq. m), an extra battery pack is helpful,
effectively doubling the work time of the lawn mower.
Remember to activate the perimeter switch because it
shuts off automatically after approximately five hours.
For a battery-powered lawn mower, the condition of the
grass will affect the how long the battery pack will run on
a single charge at each mowing. The following are some
things that affect the battery pack run time:
•
Moisture content of the grass—The more moisture
there is in the grass, the faster the battery pack will run
down.
•
Cutting height—If the battery pack is running down
too fast, raise the cutting height one level.
•
Blade Sharpness—Maintain sharp blades throughout
the cutting season. Periodically file down any nicks on
the blade. To remove the blades, refer to Replacing the
Blades on page 23.
If the finished cut lawn appearance is unsatisfactory, try
one or more of the following:
•
Replace the blades.
•
Raise the cutting height.
•
Cut the grass more frequently.
•
Set the cutting height on the front wheels one notch
lower than that of the rear wheels.
