Beating dust on the filter
CAUTION:
Do not turn the dial on the dust
case while the dust case is removed from the
dust collection system. Doing so may cause dust
inhalation.
CAUTION:
Always switch off the tool when
turning the dial on the dust case. Turning the dial
while the tool is running may result in the loss of
control of the tool.
By beating the dust on the filter inside the dust case,
you can keep the vacuum efficiency and also reduce
the number of times to dispose of the dust.
Turn the dial on the dust case three times after col-
lecting every 50,000 mm
3
of dust or when you feel the
vacuum performance declined.
NOTE: 50,000 mm
3
of dust equivalents to drilling 10
holes of ø10 mm and 65 mm depth (14 holes of ø3/8″
and 2″ depth).
