• Check to make sure that the motors' gearboxes do
not slip by blocking respective wheels. When
blocked the speed should be 0 cm/second.
NOTE! If you need to help the wheel by hand in
order for the wheel motor to start and the wheel
motor stops as soon as the wheel is blocked, the
fault is in the control box.
NOTE!
When a motor does not start and is
extremely difficult to turn by hand, except from the
wheel motor, the control box may be faulty.
• Inspect the cabling and electrical connectors on
the wheel motors and to the mower's control box.

WARNING
The blade disc rotates during the test
of the blade motor. Keep your hands

Four values are shown on the display:
• Current: xx
= an indication value of how much power is
needed to sustain 2,500 rpm. In idling mode the
normal value is approximately 40-60.
• Average current: xx
= same type of indication value as above, but
measured as an average value during
approximately 8 hours of mowing time. A high
value indicates that the blade disc is blocked.
The current and average current are the values
compared and the difference between them
determines whether the Automower should start
square mode cutting or not.
• Speed: xxxx rpm
The normal speed is approximately 2,500 rpm.
• Voltage xxV
The battery voltage should be at least 18V in order
to evaluate the function of the cutting motor.
