Evaluating cutting efficiency
The best way to determine whether a blade is
cutting efficiently is to observe the chips formed by
the cutting.
•
If chip formation is powdery, then the feed rate
is too light, or blade is dull.
•
If the chips formed are curled, but colored –
blue or straw colored from heat generated
during the cut – then feed rate is excessive.
•
If chips are slightly curled and not colored by
heat, then the blade is sufficiently sharp and is
cutting at its most efficient rate.

Maintenance
Before doing maintenance on
the machine, disconnect it from the electrical
supply by pulling out the plug or switching off
the main switch. Failure to comply may cause
serious injury.
Use a brush to loosen accumulated chips and
debris. Use a shop vacuum to remove the debris.
Make sure the chip brush on the lower band wheel
is properly adjusted.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
Wipe off the rubber tires, and clean the tables after
each day’s use.
