Maintenance
User Maintenance:
The paper bags should be replaced after every 3 hours
of use, minimum. Paper bags may need to be replaced
more often with heavy cutting and softer wood types.
NOTE: Before paper bags are replaced, the machine
must be vacuumed to remove all dust and the cloth filter
must be cleaned to remove accumulated dust. ( See the
DTV-7 Operator’s Manual for instructions on how to
clean the cloth filter)
When changing the sanding paper or screen, the foam
and dual lock “velcro” on the sanding pads should be
checked for any frays, wear, or damage.
