OPERATION MANUAL
Before any maintenance is carried out on the machine, disconnect it from the electrical supply by re-
moving the plug or switching off the main switch! Failure to comply may cause serious injury.
Lubrication
The milling machine is equipped with a “one-shot” lubrication system. The system lubricates the lead
screws and ways. Grease cups on the mill head provide lubrication for the spindle bearings and back
gear mechanism. Refer to Fig. 26 for lubrication requirements and Fig. 28 for lubrication points.

Periodic Maintenance Requirements
During operation, periodically vacuum and brush
chips and debris from the machine.
Periodically operate knee and table lead screws
through full range of movement to evenly distrib-
ute lubricant (particularly when applied using the
“one-shot” system.
Periodically apply light machine oil to work table
and other exposed metal surfaces to prevent rust
or corrosion.
BM-23A Periodically remove vent panels to check
pulleys and belts for unusual wear or grooving.
BM-53VE, BM-63VE Operators should vary speed
occasionally to prevent formation of grooves on
the pulley surfaces.
When using the coolant pump, periodically clean
the sump in the machine base to extend pump
life and promote efficient cutting. Change coolant
regularly at intervals recommended by the coolant
supplier.
