Initial Start-up And After Repairs
Before operating the machine, make sure that the drive is
filled with clean oil, approximately 0.2 US gallons(.8 L). An
accurate oil level is determined by the oil level plug, which
should be removed before oil fill.
With the gear case filled to their proper levels, start the
machine and allow sufficient time for run-in at moder-
ate pressure and speed before running at full speed.
After 4 hours of operation, recheck oil level.Mainte-
nance
Daily: - Check for oil leakage
Weekly: - Check oil level
Monthly: - Check mounting bolt torque
Oil Change Interval-Gear Drive
1. Perform the first oil change after approximately 150
hours.
2. Subsequent changes, every 1500 hours or annually,
