maintenance area and suitable personal
protection.
• The manufacturer, or an instructed
person, shall perform a technical
inspection at least annually, consisting
of, for example, inspection of filters for
damage, air tightness of the machine
and proper function of the control
mechanism.
• When carrying out service or repair
operations, all contaminated items
which cannot be satisfactorily cleaned,
are to be disposed of; such items
shall be disposed of in impervious
bags in accordance with any current
regulation for the disposal of such
waste.
• For Class M machines the
outside of the machine should be
decontaminated by vacuum cleaning
methods and wiped clean or treated
with sealant before being taken
out of a hazardous area. All the
machine parts shall be regarded as
contaminated when removed from the
hazardous area and appropriate action
taken to prevent dust dispersal.

FILTER CARE
The filters included with this vacuum are long life
filters. To be effective in minimizing dust recirculation,
the filters MUST be installed correctly and in good
condition.
WARNING: Appropriate personal
protective equipment like dust mask
and gloves should be used while
handling the filters.
To Remove Filters
1. Turn on/off/tool control switch (o) to the OFF
position (O) and unplug cord from outlet.
2. Release canister latches (d) and remove
vacuum head (c) from canister. Place vacuum
head on a level surface upside down.
3. Turn each filter (i) counterclockwise by gripping
it on the plastic end cover as shown, and
carefully remove from head, ensuring debris
does not fall into mounting hole.
NOTE: Use care to not damage filter material.
4 If the bottom side of the vacuum head (c) needs
to be cleaned, use a cloth dampened with
water and mild soap and allow it to dry. Dispose
of cloth in an appropriate container.
5. Inspect filters for wear, tears or other damage.
NOTE: If there is any doubt on the condition
of the filters they MUST be replaced. DO NOT
continue use if filters are damaged.
WARNING: Never use compressed
air or a brush to clean filters, otherwise
damage to the filter membrane will
occur which will allow dust to pass
through the filter. If needed, gently tap
against a hard surface or rinse with
room temperature water and let air
dry. Cleaning of the filters is typically
unnecessary, even if the filter is
covered with dust. The automatic filter
cleaning system will maintain maximum
performance and continue to function.
If visual damage to the filter membrane
exists, replace filters. Filters typically
last between six and twelve months
depending on use and care.
