1.4 Marking plate
In compliance with the Machine Directive 2006/42/CE on vacuum cleaners, the machine is fitted with CE
plates.
When contacting the manufacturer or dealer, always quote the details shown on the vacuum cleaner plate.
www.kruger.es

Information Section
1.5 Intended uses
These specific vacuum cleaner models have been designed, built and protected for vacuuming specifically
liquids, dusts solid materials, using special filters.
Warning!
Always use specific filters for the type of dust or materials to be vacuumed.
Any other use is considered IMPROPER.
The vacuum cleaner is in any case intended for professional industrial use.
1.6 Allowed environmental conditions
To ensure the correct operation of the vacuum cleaner, this must be positioned protected against
atmospheric agents (rain, hail, snow, fog, dusts in suspension, etc.) with an environmental running
temperature between 5°C and 45°C and relative humidity not above 70%.
The work environment must be clean, well-enough lit and devoid of explosive atmosphere.
1.7 Noise level
Noise level readings were taken in accordance with the provisions of Machine Directive 2006/42/CE
standards.
Sound tests performed on this specific vacuum cleaner model have been taken from a distance of 1 meter
and from a height of 1,60 meters, showing an acoustic pressure no higher than:
78 dB (A)
The vibrations transmitted by the machine are lower than 2,5 m2/s.
Attention!
Pursuant to articles L.D. 81/08, workers exposed to sound pressure levels above 85 dB (A) must be
protected by special individual protection devices.
It is therefore necessary, if such working conditions exist, to provide workers with such approved
individual protection devices and to inform them of the risks relating to noise exposure.
1.8 Storage
Remove the filter and clean it, empty the container and store the vacuum cleaner in a place protected
against atmospheric agents with a temperature between 0°C and 40°C. Cover with a nylon sheet to prevent
accumulation of dust.
1.9 Scrapping
In case of scrapping, all the component parts of the vacuum cleaner will have to be disposed of through
adequate disposal channels in accordance with applicable legislation.
Before scrapping, all plastic and rubber parts will have to be separated from the electrical material. Parts
made of plastic, aluminium and steel only may be recycled if collected by special centres.

Safety Section
2.1 Safety details
The person in charge of safety shall be responsible for informing workers about the risks associated with
vacuum cleaner operation.
The obligation also exists of training workers so they are able to protect themselves and others.
Failure to observe basic safety regulations and Warnings could cause accidents during vacuum cleaner
operation, maintenance and repair. Accidents can often be avoided by recognising potentially dangerous
situations before these occur. Operators should be aware of potential hazards and be trained and skilled
enough. They should also have the tools necessary to perform these duties properly.
KRÜGER TECHNOLOGY S.L. shall under no circumstances be deemed liable for accidents or damage caused
by use of the vacuum cleaner by personnel not properly trained or who use it in an improper manner, as
well as by even partial failure to comply with the safety regulations and intervention procedures indicated
in this manual.
The safety Warnings and warning notices are indicated in this manual and on the product.
Unless these hazard messages are heeded, the operator could become involved in accidents with
serious consequences for him/herself and for other people.
The safety messages are highlighted by the following symbols:
Attention!
Unless these messages are heeded, operator injuries could occur.
Warning!
Unless these messages are heeded, vacuum cleaner damage could occur.
KRÜGER TECHNOLOGY S.L. cannot foresee all possible circumstances capable of representing a
potential hazard. The warnings in this manual and on the products should not therefore be deemed
exhaustive. In the event of tools, procedures, work or machining methods being used that are not
explicitly recommended by KRÜGER TECHNOLOGY S.L., make sure no hazards exist for operators and
others.
Only ever use original KRÜGER TECHNOLOGY S.L. spare parts.
KRÜGER TECHNOLOGY S.L. declines all liability in the event of non-original spare parts being used.

Safety Section
2.2 Safety warnings
Attention!
The following indications are, by themselves, not enough to fully protect against all the hazards that
could arise during vacuum cleaner operation. These will have to be integrated with common sense and
the experience of the operator, both of which are crucial factors for preventing accidents. Each section of
this manual lists further specific safety warnings for the various operations.
Maintenance jobs must always be performed with the power plug detached from the power point.
The employer must inform and train the user according to the provisions of applicable laws.
Before using the machine, prepare and train yourself by reading this manual carefully. Use of the machine
by untrained and unauthorised persons is forbidden.
Using the machine to vacuum toxic substances is forbidden unless this has been equipped with special
filters required for the specific type of dusts. Such filters must be explicitly requested by you.
If the machine is used to vacuum toxic-harmful substances, the container must be emptied and the filters
cleaned using adequate individual protection devices, selected according to the type of substances to be
vacuumed.
Do not vacuum flammable materials or substances or which could cause explosions (fuels, solvents, etc.). To
vacuum such materials, the machine must be built with Anti-explosion Motor and Electric System and this
must be requested by you explicitly.
Do not vacuum corrosive substances unless the machine is equipped with containers suitable for this
purpose (Stainless-steel AISI 304).
Use of the machine without the supplied filters is not recommended.
If the filters are correctly fitted, the machine will not eject any objects.
Never rest miscellaneous materials on the horizontal protection guard.
The machine casing containing moving parts must not be removed by the user.
When using the machine, mind other people, especially children.

Safety Section
2.4 Outstanding risks
Careful analysis of risks performed by the manufacturer and stored in the technical file has made it possible
to eliminate most of the risks associated with vacuum cleaner operation.
The manufacturer advises carefully following the instructions, procedures and advice contained in this
manual as well as applicable safety regulations, including the use of the envisaged protection devices, both
those integrated in the cleaner and individual.
Outstanding risks associated with the vacuum cleaner could be:
Electrical maintenance risks caused by the need to work under power.
Pursuant to Presidential Decree 81/08, only trained personnel should work on the machine with the power
supply connected and this must have double earth insulation.
Risk of improper use in the presence of explosive and flammable substances.
The vacuum cleaner must not be used in environments containing substances in the form of liquids that
could vaporise at room temperature and flammable dusts and gas.
Risks of operation in humid environments.
Keep to the limits shown in this manual at chap. 1.6 Allowed environmental conditions.
Risk of erroneous interpretation of the safety pictograms.
Having identified the various outstanding risks, the manufacturer has affixed to the cleaner a number of
hazard labels in compliance with regulations relating to the graphic symbols to be used. The user must
immediately replace any safety plates that become illegible due to wear or damage.
Attention!
Removing the safety plates on the vacuum cleaner is strictly forbidden. The manufacturer declines all
liability in relation to vacuum cleaner safety in the event of failure to comply with the above indications.

Installation Section
3.1 Handling
The machine is supplied in a strong cardboard box secured with straps.
Transport the package using a fork-lift truck of adequate lifting capacity and make sure it is stable and that
weight is properly distributed on the forks.
Before starting to move, make sure the transit area is free and that there are no moving objects on the
packaging.
During movement, keep the load low for greater stability and safety.
When starting up the vacuum cleaner, move this by means of the wheels supplied.
The appliance must never be moved using fork-lift trucks or other equipment that lifts it off the floor.
If for any reason the need arises to lift and transport the vacuum cleaner, this operation must be performed
under the responsibility of the user. The user is therefore invited to secure the load as he best thinks fit to
ensure the operation is performed in total safety.
