Filter Care - DeWalt DWV902L User Manual


WARNING: For user servicing, the machine must be
dismantled, cleaned and serviced, as far as is reasonably
practicable, without causing risk to the maintenance staff
and others. Suitable precautions include, decontamination
before dismantling, provision for local filtered exhaust
ventilation where the machine is dismantled, cleaning of
the 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 the filter 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.
• For dust extractors it is necessary to provide for an
adequate air change rate L in the room if the exhaust
air is returned to the room.
(NOTE: Reference to National Regulations is
necessary.)

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
and unplug cord from outlet.
2. Release canister latches 4
from canister. Place vacuum head on a level surface upside
down.
3. Turn each filter 9 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

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.
To install Filters
