SECTION 6: MAINTENANCE

Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person-
al injury.

Schedule

Ongoing
To maintain a low risk of injury and proper
machine operation, if you ever observe any of the
items below, shut down the machine immediately
and fix the problem before continuing operations:
• Loose mounting bolts or fasteners.
• Worn, frayed, cracked, or damaged wires.
• Guards or covers removed.
• Emergency Stop/RESET button not working
correctly or not requiring you to reset it before
starting the machine again.
• Oil level not visible in the sight glasses.
• Damaged or malfunctioning components.
Daily, Before Operations
Check/add headstock oil (Page 60).
•
Check/add gearbox oil (Page 62).
•
Check/add apron oil (Page 62).
•
Lubricate the bedways (Page 63).
•
Clean/lubricate the leadscrew (Page 63).
•
Add oil to the ball oilers (Page 63).
•
• Disengage the feed selection lever on the
apron (to prevent crashes upon startup).
• Ensure carriage lock bolt is loose.
• This machine has two fans for the VFD in the
electrical box. Make sure that one fan draws
air in and the other fan pushes air out. Make
sure fan filter screens are clean and air flow
is not blocked. An overheated VFD and/or
electrical box will shorten the life of the VFD.

Cleaning/Protecting

Because of its importance, we recommend that
the cleaning routine be planned into the workflow
schedule.
Typically, the easiest way to clean swarf from the
machine is to use a wet/dry shop vacuum that is
dedicated for this purpose. The small chips left
over after vacuuming can be wiped up with a
slightly oiled rag. Avoid using compressed air to
blow off chips, as this may drive them deeper into
the moving surfaces or cause sharp chips to fly
into your face or hands.
All unpainted and machined surfaces should be
wiped down daily to keep them rust free and in
top condition. This includes any surface that is
vulnerable to rust if left unprotected (especially
parts that are exposed to water soluble cutting
fluid). Use way oil to prevent corrosion.
