USING VACUUM CLEANER
The random orbit sander can also work with
FLEX vacuum cleaner model FX5221 to
conduct dust extraction.
Connect one end of the power-tool adapter
(included with the vacuum cleaner) to the nozzle
pipe of the vacuum cleaner, and the other end
into the dust port of the sander (Fig. 5).
Make sure the sander and the cleaner are firmly
connected.
