Drive System Maintenance; Changing The Transmission-Oil Filter; Checking The Rear Wheel Alignment - Toro 02750 Operator's Manual

WARNING
Incorrect battery cable routing could damage the
machine and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
Check the battery condition weekly or after every 50 hours
of operation. Keep the terminals and the entire battery case
clean because a dirty battery will discharge slowly. To clean
the battery, wash the entire case with a solution of baking
soda and water. Rinse it with clear water. Coat the battery
posts and cable connectors with Grafo 112X (skin-over)
grease (Toro Part No. 505-47) or petroleum jelly to prevent
corrosion.

Checking the Rear Wheel
Alignment
Service Interval: Every 500 hours
To prevent excessive tire wear and ensure safe machine
operation, the rear wheels must be correctly aligned to 3 to
8 mm (0.12 to 0.31 inches).
1. Set the rear wheels in the straight ahead position.
2. Measure and compare the distance between the front
sidewalls and the rear sidewalls at the wheel center
height (Figure 41).
Note: The distance between the front sidewalls must
be set 3 to 8 mm (0.12 to 0.31 inches) less than the
distance between the rear sidewalls.
