6.1 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.
6.2 Changing the jaws
Keep clean with wire bush to avoid slippage. To replace jaws:
� Unplug machine
� Remove spindle cover
� Remove jaw retaining rings and slide jaws off shaft
If machine has been used for only right hand threading, reverse jaws and remount on jaw shafts
so that the unused side faces spindle opening.
� Inspect jaw shaft keys for wear.
� Install replacement jaws so that single row jaws (1) are the opposite of each other and
doubles (2) are opposite each other. Also alternate single and double jaws between front (3)
and rear chucks (4).
6.3 Daily inspection
Attention! Before starting the lubrication-works the power plug has to be
taken out of the power source.
� Check the mains plug, mains cable and extension cable to ensure they are undamaged.
� Correctly filled oil trough
� Adjust the oil screw if necessary
� Clean the oil tank if there are impurities in it.
