BM-20 PLUS Operator’s Manual10
To obtain the maximum bevel width
(21 mm, 13/16’’) in two passes, the bevel after
the
first pass should be about 14 mm (9/16’’) wide, while for three passes about 12 mm
(1/2’’) wide after the first pass and about 16 mm (5/8’’) wide after the second one.
If the maximum permitted motor load is exceeded, resulting from, for instance,
too fast feed, the red overload lamp will light. Continuing the operation in such a case
will trigger the safety circuit and shut down the motor. If as a result of an overload the
motor will shut down, separate the machine from the working edge, turn off the power
by setting the power switch in position ‘O’, and after the red overload lamp turns off,
power on the machine again.
Operating near the overload condition (with the red lamp flashing) is allowed,
however, never allow the motor temperature to exceed 85°C (185°F) as this can lead
to damage of the motor windings. After every one hour of operating under full load,
stop the motor for 10–15 minutes. Never cool the motor by running it without load as
it will become heated even faster than when working with load.
Once the work is finished, stop the motor using the STOP button and toggle the
power switch to the position ‘O’.
Clean the machine with a cotton cloth without using any agents.
