Wheel Hub Oil
Bonfiglioli Wheel Hubs
Each wheel hub should maintain a proper
oil level at all times. Less than that would
limit lubrication and overfilling would cause
overheating and machine damage.
To check the oil level:
NOTE: Check wheel hub oil level every 100
hours of operation.
1. Position wheel hub so the bottom (oil
drain) face plug is positioned at 6 o’clock
(A).
