Friendly Robotics Robomow RL350 Operating & Safety Manual page 36

The Power Pack should be fully charged before initiating any operation. In addition, you should have
examined the mower before operation to look for problems that may cause excessive energy consumption
and thereby less than optimum run-time. Examples include dull blades or heavy grass accumulation
around the blades. Other examples can be found in Chapter 6 Text Messages and Troubleshooting. First
and foremost, insure that the Power Pack is indeed fully charged before putting it to work. Only when the
LCD displays the message in Figure 4.5 is the Robomow fully charged and ready for mowing. And lastly,
use the Robomow for the job it was designed to do, cutting normal levels of grass growth.
The Robomow can operate under two different run-time scenarios; 1) operate the maximum time allowable
by the system, where this time is dictated solely on the remaining level of energy in the Power Pack and 2)
where the run-time is set to operate a fixed amount of time set by the user, such as one hour for example.
Maximum operation will always display 'Recharge Battery" after the cutting session and a fixed time will
display 'Time Complete' after the session. Under either of these operating scenarios it is important to
retrieve the Robomow and place it on the charger as soon as practical, preferably within 6 hours from the
time it stops operation.
The 'Recharge Battery' level has a higher priority in the power management system than 'Time
Completed' for the obvious reason that the Power Pack voltage is at a lower level. For this reason,
immediately following a 'Recharge Battery' message the Robomow will emit a buzzer sound every 30
seconds for the next 20 minutes in order to alert you that the mowing session is completed and it is now
time to re-connect the charger to the Robomow. If the Robomow is not connected to the charger within the
next 21 hours, a higher-level alarm will sound. If the charger is still not connected after this alarm series,
the mower will enter a deep sleep mode to conserve power. If the Robomow enters a deep sleep mode,
the Power Pack must be removed for 10 seconds and then re-inserted in order to wake up the Robomow.
However, if the mower reaches this level and the charger is not connected soon, you risk causing poor
performance and service life to the Power Pack.
Similar alarms will alert you to connect the charger if not connected after a fixed time, when operating
under fixed run-time settings. Lastly, if the charger is disconnected, even after the fully charged message,
the alert system will operate to remind you to keep the charger connected until ready to use for mowing.
4.4 Off-season storage
When preparing the Robomow for off-season storage, first fully charge the Power Pack and then store it
separately from the Robomow in a dry location where the temperature will not drop below -20 ºC (-4ºF).
Recharge the Power Pack every three months while in storage.
Important!
For more details regarding the winter storage please refer to section 8.8.
