WARNING
Quickly dispose of the dust without letting it accumulate.
Even if the dust is non-flammable, the dust could catch fire or explode
depending on the particle size, concentration, or other conditions, so be
careful when removing any kind of dust.
Since an unexpected problem could occur in the disposal of mixed
collected dust, we ask that the customer be responsible for making this
determination.
CAUTION
To prevent a fire accident, always check the dust after conducting work
that generates sparks, etc., and inspect the unit before concluding the
work for the day.
If the front cover is not attached properly, the vacuum force could drop
or overloading could cause the motor to burnout, so make sure the
cover is attached properly.
Turn off the operation switch and make sure the fan has completely stopped
rotating. Not doing so could result in the collected fine dust being blown
around.
Unlock the thumb lock and take off the front cover.
Remove the internal filter unit.
Remove the filter unit dust.
Dispose of the dust in the draw tray.
Install the filter unit back in its original location.
Insert the front cover and completely close the thumb lock. If the front cover
is not properly installed, it could cause the vacuum force to drop or overload
the motor and cause it to burn out.
