FILTER MAINTENANCE
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off machine
and remove key.
The filter is one of the machines main components. It
is essential for the best results from your machine. If
you notice that dust forms when the machine is at
work, check the filter by performing the following
steps:
1. Press and release the filter shaker lever. The
lever operates a rod that will unclog the filter.
Repeat this operation 5 or 6 times (Figure 3).
2.
Apart from the filter shaker, it is advisable every
now and again to remove the machine’s filter and
clean it out with a blast of air or a vacuum cleaner.
For this purpose, the filter is removed as follows:
a.
Unlatch and turn rear bin latches inward.
b.
Remove the rear bin.

NOTE: The filter features an arrow that shows you the
direction in which it should be fitted.
DUSTY ENVIRONMENTS: If you are using the
machine in a particularly dusty environment (cement
factories, sawmills, marble processing factories), it is
wise to use the filter shaker more frequently.
3.
Every 200 hours of work, the filter must be
replaced. Follow the operations listed in step 2.
After the filter has been remounted, make sure the
gasket and filter are dust tight.
ATTENTION: Waste must be disposed of strictly in
accordance to the law.
