4. USE
4.2 Using the timer
The lawn should not be cut too often to obtain the
best mowing result. Use the timer function (see
6.3
Timer (1)
to avoid a downtrodden lawn and to get the
maximum life from your R40Li. When setting the
timer, calculate that R40Li mows around 30 m
2
per
hour and day. For example; if the working area is 300
m
2
, the mower must operate for 10 hours a day.
The factory setting for the timer is 07:00-22:00 and it
can operate every day of the week. This setting is
suitable for a working area of about 400 m
2
.
The R40Li has an inbuilt standby period of at least 11
hours a day. The standby period provides for instance
a good opportunity to water or play games on the
lawn.
If the timer setting is divided into two work hours, the
standby period can be divided into a number of
periods. The maximum operating time can however
be a maximum of up to 13 hours. When in operation,
the mower alternates between mowing and charging.
Example 1
Work hour 1: 07:00 - 22:00
Week days: All days
The factory setting ensures that the mower
begins cutting the lawn at 07.00. The mower is
parked in the charging station from 22.00 and
rests until it starts cutting again at 07.00.
Example 2
Work hour 1: 06:00 - 16:00
Work hour 2: 20:00 - 23:00
Week days: All days
The mower will operate between 06:00 and
16:00. It will begin again at 20:00 but stop
running at 22:00 to rest until it starts again at
06:00.
Example 3
Work hour 1: 20:00 - 06:00
Weekdays: Monday to Saturday
The mower will operate from Monday 00:01 to
Saturday 23:59. As this work hour entails an
operational period of 10 hours a day, there is no
need to stop operations to obtain the correct
standby period.
The above times are approximate. The times depend
for instance on grass quality, knife sharpness and
battery age.
If the size of the working area allows it, the quality of
the grass can be further improved if it is cut every other
day instead of a few hours every day. In addition, the
grass benefits from resting completely during at least a
three-day period once a month.
