6.15.8 To replace the tilt sensor
The tilt sensor is integrated in the motor control circuit
board. The sensor cannot be replaced separately. The
motor control circuit board must be replaced as one unit.
Refer to
To replace the motor control circuit board on
page 26
.
6.16 The battery system
WARNING: Use only original batteries
recommended by the manufacturer. Product
safety cannot be guaranteed with other
batteries. Do not use non-rechargeable
batteries.
The battery is considered to be fully charged when the
battery reaches 80% of the total capacity. To charge the
battery to 100% would take too long since the charging
current is low. The most rational way of using Li-ion
batteries is therefore to stop charging at 80%. The
maximum utilised capacity is thus 80% of the battery’s
total capacity.
The battery is maintenance-free, but has a limited life
span. The battery is expected to last for 3000 - 4000
charging cycles. The normal charging current is 1.3 A.
