Adjusting the Cutting Height
Note: Stop and release the switch lever, then wait
for the motor to stop before adjusting height. The
blades will continue to spin after the mower has
been switched off, and these blades can still cause
injury.
For the first cutting of the season, a high cutting
adjustment should be selected. The mower can be
set to 6 different cutting heights between 25mm
and 75mm high. Press the height lever inwards, then
lift or push down the mower until the desired height is selected.
Operations
Usage Tips
Under normal conditions, the battery should run for approximately 30 minutes
on a single charge. This operation time and the area that can be mown on a
charge is dependent on several factors. These are:
Type of lawn: Battery-powered lawnmowers are
suitable for lawns which are mown frequently.
For example, battery-powered mowers are not
suitable for infrequently-mown meadows or
overgrown thickets or similar. To produce a
well-maintained lawn, we recommend mowing
the lawn as often as you can, once a week if possible. This would mean that you
are only cutting 1 to 2 inches (20mm to 50mm) of grass each mowing session
(see image to right). Trying to cut more than 2 inches (50mm) will drastically
reduce the charge life of the battery and quality of the cut. After relatively long
intervals between mowing (holiday lawn), firstly cut in one direction with the
cutting height as high as possible, then cut in the crosswise direction at the
cutting height required.
Lawn structure: The area that can be mown decreases in proportion to the
density of the grass. The mowing capability is lowest on extremely dense grass,
(e. g. golf greens, which are not suitable for battery-powered lawn mowers to
mow).
Law n condition: Tall, thick, or damp grass make the Mower work harder, causing
the battery to discharge faster. Under normal mowing conditions the run time is
around
30 minutes. To mow longer, consider purchasing a second battery and
keep it fully charged. Before starting the mower, adjust the cutting height so
that you only cut 1 to 2 inches (20 mm to 50mm) of grass at a time. Cut thicker
grass at a higher cutting height, or cut a narrower swath. Do not force the
mower forward in tall, thick or wet grass.
