The depth gauge should be maintained at a
clearance of 0.635 mm (0.025"). Use a depth
gauge tool for checking the depth gauge
clearances.

Use a flat file and a depth gauge jointer to lower all
gauges uniformly. Depth gauge jointers are
available in 0.5 mm (0.020") to 0.89 mm (0.035").
Use a 0.635 mm (0.025") depth gauge jointer. After
lowering each depth gauge, restore original shape
by rounding the front. Be careful not to damage
adjoining drive links with the edge of the file.
Depth gauges must be adjusted with the flat file in
the same direction the adjoining cutter was filed
with the round file. Use care not to contact cutter
face with flat file when adjusting depth gauges.
