DIFFERENTIAL OIL LEVEL CHECK
The dipstick for the differential oil is located under the operator’s seat. Add 90W gear lube if necessary, to
bring the oil level up to the indentation in the dipstick (approximately 1 inch / 2.57 cm from the tip).

WHEEL MOTOR - CARBON BRUSH INSPECTION
The carbon brushes in the wheel motor should be checked every 1000 hours of operation. To check the
carbon brushes, tip the operator’s seat forward and carefully remove one of the brushes from the motor. If the
brush is worn to a length of 3/8 inch (10 mm) or less, remove the motor from the machine and replace all the
brushes.
