Manual test: Test of wheel motors
1. Click on the Wheel motors > button.
Click on the right arrow or left arrow to
increase respective reduce the force. One click
represents a 5% increase/reduction. 100%
wheel force gives maximum speed.
2. Read the values in respective boxes and bars.
3. Click on Wheel motors < to reverse the direction
of the wheel motors.
4. Click on Stop to end the test.
IMPORTANT INFORMATION
Lift up the rear wheels on the mower before
starting the wheel motors. Otherwise the
mower will drive off and may damage the
service cable.
Manual test: Testing the blade motor
WARNING
The blade disc rotates during the test
of the blade motor. Keep your hands
and feet at a safe distance.
1. Click on the Blade motor > button.
2. Read the value in the box and on the bar.
The value/blade motor speed should be about
2,500 rpm.
3. Click on the Blade motor button> to start the
mower in the opposite direction.
Manual test: Testing the charge
If charging works well, the horizontal bar with Battery
current is green. When the mower is maintenance
charged, the charging current can be negative and the
battery bar red. Press the Charging on button (1 min)
to switch on charging at full current.
The solar panel on Solar Hybrid can supply
600-700 mA in the most favourable operating
conditions. This means outdoors, during the summer,
in the middle of the day, with a clear sky and at right
angles to the sun. In order to create a repeatable test it
is recommended to use a 500 W halogen construction
When testing the wheel motors:
• Increase the force to 80% and block
respective drive wheels in at least ten different
positions over the wheel revolution. Check
that the motor starts again once blocking is
released.
• Increase the force to 100% and check that
the speed of each wheel is at least
45 cm/seconds (60 cm/seconds for 230 ACX).
• 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
fromthe 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.
