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.
When the wheels rotate forwards a positive
value is shown in the value box and a negative
value is shown when they rotate backwards.
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.
4. Autocheck, Service program
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.
• 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.
