2.1 Safety details
The person in charge of safety shall be responsible for informing workers about the risks associated with
dust collector 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 dust collector
operation, maintenance and repair. Accidents can often be avoided by recognizing 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.
NFE shall under no circumstances be deemed liable for accidents or damage caused by use of the dust
collector 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:
Warning!
Unless these messages are heeded, operator injuries could occur.
Caution!
Unless these messages are heeded, dust collector damage could occur.
NFE 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 NFE, make sure
no hazards exist for operators and others.
Only ever use original NFE spare parts.
NFE declines all liability in the event of non-original spare parts being used.

2.2 Safety warnings
Warning!
The following indications are, by themselves, not enough to fully protect against all the hazards that
could arise during dust collector 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 source.
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 unauthorized 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 Longopac® bag 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 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 emit any dust.

How to Use the Table
1. Determine your supply voltage.
2. Determine the total length of your cord including all extension cords.
3. Determine the maximum amp draw for your machine.
4. Trace your voltage across the top of the table to the first length that is greater than or equal to your
cord length.
5. Follow the column down to the first row that contains a maximum amp draw greater than or equal to
yours.
6. This cell contains the minimum wire size for your application.
Example
Application: Max Amps = 11A, Length = 80ft, Voltage = 230V 1ph
Solution: 80ft is between the 50ft and 100ft columns, so the
larger of the two columns is chosen. Likewise, 11A is between the
10A and 12A rows, so the larger of the two rows is chosen. 14
AWG (2.5mm2) is the minimum wire size for this example.
Extension Cord Sizes
Note: The table is based on a ˂10% voltage loss, data from the U.S. National Electrical Code Tables 400.5(A)
& 400.5(B) and typical resistances for copper wire.
