2) Filter cleaning process
The machine is designed for filter cleaning by reverse air “jet-pulse”.
The filter must be cleaned from time to time. This must be done before changing
the bag collection system and should also be done when work is completed or
whenever there is a poor suction.
Filter cleaning procedure:
Cover the inlet by lifting up the inlet valve and let the machine build up
vacuum for 4 to 5 seconds,
Quickly push down the filter cleaning handle and release it. Repeat the
procedure five times. It is important to let the machine rebuild the vacuum in
between every repetition,
Open the inlet again by pushing down the invlet vavle.
If suction remains poor, the conical main filter needs to be replaced. If suction
still remains poor afterwards, the HEPA filters needs to be replaced. See
instructions in chapter 13 Filter change.
3) Dust storage and release
The separated dust accumulates in the conic bottom during the vacuuming
process, and it drops through the bottom flap into the plastic bag when the
machine is switched off. In some extreme cases the adhesive ability of the dust
must be broken manually. This can be done by hitting the dust through the bag
or tapping the tank using i.e. a rubber hammer.
4) Dust collecting and bagging
The machine is equipped with a continuous fold bag system for an effective dust
collecting and bagging. The supplied fold bag is a 22 m long plastic tube that
will be divided into individual bags using the zip ties attached with the machine.
To assemble a new fold bag:
Release the belt holding the last bag and take off the bag holder.
Put in a new fold bag & pull out the inner end upwards.
