Central lubricating system

Proper lubrication of the spindle bearings and brake band
is essential for trouble-free operation and long life for the
machine. The central lubricating system makes this a very
easy procedure.

Check the reservoir and refill if necessary with SAE 30
weight lubricating oil into inlet.
Once a day, before starting the machine for the first
time, lift and release the lubricator plunger six times.
During normal operation, lift and release the plunger

four times every two hours of operation.
Replace filter element once a year on the central
lubricator pump.
