Cleaning the Machine
Maintenance Service Interval | Maintenance Procedure |
---|---|
After each use |
|
After each use, wash the machine with mild detergent and water. Do not pressure wash the machine. Avoid excessive use of water, especially near the shift-lever plate, the InfoCenter, the power center, and the machine power connector. Clean the motor to provide proper cooling during operation. Also, keep the battery pack as clean as possible so that it maintains a white color. This reflects sunlight and keeps the battery from overheating in the sun.
Important: Do not use brackish or reclaimed water to clean the machine.
Important: Always store or park the machine out of direct sunlight, as heating from the sun reduces the battery-pack life span.
