Sharpener Maintenance
DANGER!
Swarf (metal filings) must be cleaned and removed from
the oil pan and filter magnets every 8 hours of operation to avoid possi-
ble fire. Failure to do so may result in death or serious injury.
Daily (after end of the shift):
Remove the blade, wipe the sharpener dry, lower the head, close the guard and unplug the
machine after each day’s use.
Clean the sharpener. Remove any rust and metal filings. Clean sediment from the oil pan and
filter magnets.
Regularly unbolt the moving clamp plate and clean out any buildup that might cause the clamp
to not clamp the blade firmly.
Weekly:
Clean the viewfinder window and the diode lamp.
Remove any buildup and metal filings from the oil filter pan and magnets.
Clean any sediment from the coolant drip pans.
Keep the oil at such a level that the pump strainer is completely covered with the oil. The oil
level should be 120-150mm (4.724" - 5.905") measured from the bottom of the tank. Replace
the oil completely every six months. Dispose of worn-out oil in compliance with applicable
regulations.
Check the sharpener head stop function (stop bolt).
Monthly:
Inspect the bearings of the grinder motor, spindle, cam and indexer drive assembly, sharpener
head lever.
Check motor and indexer brushes.
Check all plugs and switches.
Check the radial run-out and the axial run-out of the spindle shaft at the location where the
grinding wheel is mounted. Do it once a month with a dial indicator mounted on a magnetic
stand. The maximum allowable run-out must be no greater than +/- .01mm (0.000393").
Inspect the carbide cutting plate of the deburr assembly.
