IMPORTANT

This machine may be equipped to handle hazardous dusts.  This is only possible if fitted
with a HEPA filter module.  Always take caution when emptying the machine as the dust
found in the container may be hazardous to your health.

If the machine will not run, check that the it is switched on and that power is available.  If
the machine stops in use and restarts after a time, the high temperature cut-off device
may be activated.  This may be indicative of blocked main filters, a blocked HEPA filter
or blocked hoses.

Servicing

Any servicing required should be carried out by qualified personnel.

Do not attempt to clean the microfilter cartridge.  If it becomes excessively clogged, fit a
new unit.  Take care when fitting the new cartridge not to handle or rupture the paper
element as this will affect the filtration efficiency of the machine.  Care should also be
used in disposing of the old cartridge.

Always use genuine Numatic parts for any repairs required.
