Cleaning Sensors and Wheels
Cleaning sensors
Þ
Clean (blow or wipe) the three sensors with the included clean-
ing brush or a cotton swab.
If sensors are severely contaminated, wipe with a moistened
cotton swab.
Do not wipe directly with water, and do not use benzene or
alcohol to clean sensors.
Cleaning wheels
Þ
Clean wheels using the brush.
To clean the front wheel, remove the screws and remove the wheel, and clean it with the brush.
To clean the two main wheels, clean them with the brush while rotating slightly by hand.
Remove foreign objects such as hair that obstruct the wheel’s operation.
