Be sure to maintain the dust collector at regular intervals. This is important to prevent the
machine’s failure or accident and keep it serving you for many years to come. During the
maintenance work, always turn off the power supply to the machine and when replacing the filter
cloth use protective goggles and gloves and a dustproof mask.

Maintaining the FR unit
Discharge the drainage before the bowl is
filled by turning the drain cock of the FR
unit.
In case a large amount of drainage is
generated, replace the FR unit with a
commercially available auto-draining
version or install a dryer on the midway of
the upstream side of the air piping.
Clean the filter at regular intervals by
washing them with detergent. To do this,
detach the filter by turning off the bowl and
the baffle.
When disassembling the FR unit, be sure to release the residual pressure of compressed air.
