Robomower RL500/RL550/RL800/RL850
Safety Features
1. Child Guard / Safety Guard
This menu option offers a safety feature to help prevent children or others not familiar with the
safe operation of the mower to operate it freely.
2. Lift Sensor
There is a sensor located on the front caster wheel of the mower. In the event the front of the
mower is raised approximately 1-inch from its resting position on the ground during blade
operation, the blades will stop rotating immediately (< 1 second).
3. Sensor Equipped Bumpers
The front and rear bumpers are equipped with contacts that will activate when the mower
strikes a solid, fixed object when that object is at least 6-inches in vertical height from the
supporting surface of the mower. When the bumper sensor is activated, the mower will stop
movement in that direction and reverse itself away from the obstacle. In manual blade
operation, bumper activation will stop the rotation of the blades immediately (<1 second).
4. Emergency Stop Switch
Located on the top outer surface of the manual controller, red in color. Pressing this button at
any time during operation will stop all mower movement and stop the rotation of the blades
immediately (<1 second).
5. Automatic Mode Recognition
The Robomower is designed so that it cannot be operated in the manual mode while the
Manual Controller is in its' pocket and it cannot operate in the automatic mode while the
Manual Controller is removed.
6. Two-Step Operator Presence Control
While in manual mode, it requires two independent finger actions in order to engage the
mower blades. Once engaged, the mower blade button must remain depressed to continue
blade operation. Once released, the two-step engagement process must be repeated.
7. Electronically Controlled Charging System
The Robomower is equipped with an on-board charge control system. This allows you to
keep the charger connected at all times, even after the battery is fully charged. The contror
system will prevent an overcharge to the battery and keep it fully charged and maintained for
the next use.
8. Sealed Power Pack
The power pack that operates the Robomower is completely sealed and will not leak any type
of fluids, regardless of position. In addition, the power pack contains a one-time-use fuse in
the event of a short-circuit or power malfunction.
