Maintenance
Keep the maintenance of the machine tool during the operation to guarantee the accuracy and
service life of the machine.
1. In order to retain the machine's precision and functionality, it is essential to treat it with care, keep
it clean and grease and lubricate it regularly. Only through good care, you can be sure that the
working quality of the machine will remain constant. Disconnect the machine plug from the
mains supply whenever you carry out cleaning, maintenance or repair work!
2. Lubrication all slideways lightly before every use. The leadscrew must also be lightly lubricated
with lithium base grease.
3. During the operation, the chips what falls onto the sliding surface should be cleaned timely, and
the inspection should be often made to prevent chips falling into sliding ways. Asphalt felt should
be cleaned at certain time. Do not remove the chips with your bare hands. There is a risk of
cuts due to sharp-edged chips.
4. After the operation every day, eliminate all the chips and clean different part of the machine and
apply machine oil to prevent rusting.
5. In order to maintain the machining accuracy, take care of the arbor, drawbar, the surface of the
worktable and the guide way and avoid mechanical damage and the wear due to improper guide.
6. If the damage is found, the maintenance should be done immediately.
