8. Electric safety
Improper connection of the equipment-grounding conductor can result in a risk
of electrical shock. Check with a qualified electrician or service person if you are
in doubt as to whether the outlet is properly grounded.
Do not modify the plug provided with the machine. If it will not fit the outlet, have
a proper outlet installed by a qualified electrician.
Before using the machine, make sure that the power & voltage corresponds with
the voltage shown on the machines rating plate.
Do not leave machine when plugged in. Unplug cord from outlet when not in
use and before cleaning or servicing machine.
Cables damaged through crushing or splitting can be dangerous if used and
should be replaced immediately. Risk of personal injury.
Do not use with damaged cord or plug. If the machine is not working as it should,
has been dropped, damaged, left outdoors or dropped in water. Make sure it is
repaired by a qualified person.
Do not pull or carry by cord, use cord as handle, close a door on cord, or pull
cord around sharp edges or corners. Do not run the machine over cord. Keep
cord away from heated surfaces.
Do not unplug by pulling on cord. To unplug, grasp the plug. Not the cord.
Do not handle plug or machine with wet hands.
Regularly inspect cord and plug for damage. If cord is damaged, it must be
replaced by a qualified person in order to avoid hazard.
Turn off all controls before unplugging.
If using an extension cord make sure the cord rating is suitable for this machine.
Connect to a properly grounded outlet only. See grounding instructions.
9. Thermal protection
The dust extractor is equipped with a safety thermal protector to prevent motor from
overheating. Should thermal protector activate, turn off machine, unplug power
cord and check for full dust bag, vacuum hose clog or filter blockage. It may take
up to 45 minutes for the thermal protector to reset.

page- 10
Operating Manual G12/G18/G22/G32
2020 rev. 4.0
10. Grounding instructions
The dust extractor must be grounded. If a dust extractor malfunctions or
breakdowns, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. The dust extractor is equipped with a cord having
an equipment-grounding conductor and grounding plug. The plug must be inserted
into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
11. Service
When cleaning and servicing the machine, you must switch off the machine and
remove the plug from the outlet.
Don’t clean the machine with a high pressure cleaner. If necessary, do not
direct at the openings on the machine, especially the opening for cooling air.
Before moving the machine from the work area, the machine must be cleaned.
Proper personnel protective equipment must be used while replacing the main
filter or the HEPA filter. If possible, use a special suitable room.
All parts which are contaminated after service must be properly disposed of in
plastic bags according to all regulations.
If the machine has to be used for other purposes, it is extremely important that
the machine is cleaned, to avoid the spread of hazardous dust.
Do not puncture the HEPA filter. Risk of dust dispersion.
12. Operating Instructions
1) Vacuuming process
Before starting a vacuuming process,
make sure the machine is properly connected to a grinder or a floor tool via
the provided hose and fittings.
chek the power cable and the plugs are in a good condition.
make sure the power voltage corresponds to that on the rating plate and
connect correctly the power plug to a power socket
Turn on the power switch to start a vacuuming process.
During the vacuuming process, dust-laden air is sucked through the flexible hose
and inlet valve at a high speed. The air is then slowed down by the cyclone, and
coarse dust particles are separated out partly by centrifugal force and partly by
gravity. Air and finer particles pass through the main filter at the first and the
HEPA filter at the final stage where separation is made.

page- 11
Operating Manual G12/G18/G22/G32
2020 rev. 4.0
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.

page- 12
Operating Manual G12/G18/G22/G32
2020 rev. 4.0
Assemble the holder onto the machine and strap the opening facing upwards
with the belt.
Pull down the outside end and close it using a zip tie.
Before changing a fold bag or a regular bag, make sure the filter cleaning cycle
has been completed.
13. Filter change
Unhealthy dust can be spread during filter change. Accordingly, the user should
wear protective glasses, protective gloves, and a breathing mask conforming to
protection class FFP3.
WARNING! Remember to switch off the machine and pull the plug out of the outlet
before servicing.
1) Change of main filter
Loosen the 3 hooks and remove the top cover. Take out a new filter from its
bag. Lift out the used filter from its chamber and place it gently into the filter
bag. This bag must be closed and diposed properly.
Insert a new filter.
Put back the top head and close the 3 hooks properly.
IMPORTANT! If you are removing the main filter in order to clean it. Hitting the
filter with force or use of compressed air will destroy the filter. It can handle water,
but high pressure water cleaning will destroy it.
2) Change of HEPA filter
Loosen the 2 nuts on each filter cover. Take out a new filter from its bag. Lift out
the used HEPA filter from its chamber and place it gently into the filter bag.
This bag must be closed and diposed properly.
Insert a new filter to the filter chamber.
Put back the filter cover and close the 2 nuts properly.
IMPORTANT! HEPA filters can’t be cleaned, trying this might destroy it. When
installing the replacement filter, make sure not touch the inside of the filter. Any
kind of force/damage on the inside of filter media will destroy the new filter.

14. Problem solving
The machine is designed and manufactured for a specific severe environments and
tasks. Its filter, seals, attachments, and fittings are customized or selected specifically
