3. Cleaning / Maintenance
Always unplug the unit from the wall outlet
before beginning any cleaning or mainte-
nance tasks.
Examine the power cord regularly, but at
least annually, for damage or signs of
aging. Immediately replace damaged power
cords.
3.1 Seals
To ensure the proper function of the dust extractor, it
is vital that the following three seals:
• Profile seal on the dust drawer (Fig. 12a);
• V-ring seal on the dust drawer (Fig. 12b);
• Seal on the upper front panel (Fig. 20);
are not damaged.
Inspect these seals when replacing the associated
filters and replace them if they are found to be
damaged (refer to the spare parts list).
3.2 Replacing the Dust Bag
The dust extractor may only be operated with a
complete filtration system. The dust bag must be
immediately replaced with a new one as soon as the
“Change Filter” indicator goes on.
Failure to replace the dust bag may result
in it’s rupturing. Depending on the material
in the bag, this may lead to hazards for the
operator. In addition, the dust extractor may
be damaged.
• Pull the front panel forward and off (Fig. 8).
• Pull the dust drawer out towards the front (Fig. 9).
• Leave the dust bag in the dust drawer and take it to
the disposal location.
• Remove the dust bag from the drawer.
• Take off protection film, cover filter opening
(Fig. 10).
• Dispose the dust bag accordingly.
Always comply with all local ordinances
governing proper disposal and accident
prevention!
Depending on the filter contents, protective
clothing may be required.
• Insert the new dust bag into the dust drawer, being
careful to ensure that the dust bag is properly
aligned in the guide grooves and the glue lap faces
up (Fig. 11).
Use only original Renfert dust bags
(refer to the spare parts list).
• Inspect the dust drawer seal for damage and
replace it, as required (Fig. 12a, b).
• Insert the dust drawer, making sure it is straight,
and push it fully against its stops. Make sure the
dust drawer is seated correctly on the guide
(Fig. 13).
• Install the front panel on the bottom hooks first
(Fig. 14), then push it into the upper lock bolts,
pressing firmly until it locks in place (Fig. 15).

NEVER operate the dust extractor without
