8. Maintenance and inspection

General notes:
Maintenance, cleaning and repair work may only be
carried out after the machine is protected against
accidental starting by pulling the mains plug.
After each use, remove chips and sawdust.
Clean the machine regularly.
Periodically lubricate gently with grease:
-the drive splines (grooves) in the spindle
-the teeth of the quill
-the rack
Periodically apply a light film of oil to quill and column.
This will reduce wear, prevent rust and assure ease of
operation.
Exposed metal surfaces of table and base should be kept
clean and free of rust. Apply protective spray or paste wax.
Check that bolts all are tight
Check that electrical cords are in good condition.
Make sure the motor fan and fan cover are kept clear of
sawdust. Periodically blow out any dust.
Periodically check the proper function of the safety devices.
-Chuck guard limit switch
-Pulley cover limit switch
-E-stop button
Defective safety devices must be replaced immediately.
