2. Description of the B2 AIR

The B2 AIR device is only intended for the following activities:

The B2 AIR is solely intended for de-burring metal materials at the shop or the manufacturing

plant.

This entails a manual, hand-operated machine. The main advantages of this machine are its

ability to machine straight as well as shaped pieces, opening and pipes. The B2 AIR can also

perform the rounding of edges of pieces. A special cutting blade is necessary - see the text

below - for this application.

Use the machine only in an environment protected against rain, snow, and other unfavorable

effects of the environment.

3. Identifying Data

Identifying data of the B2 AIR machine are stated on the label attached to the body of the

machine.

4. Tests

The machine for removing corners is tested in our technical laboratory.

During this test, the correct function of de-burring of sheet metal and profiles of various types

and sizes.

Using other than original and producer approved spare parts and accessories for a given

model

Full or partial non-compliance with the instructions of this manual

Extraordinary events, natural calamities, or others

6. Safety Regulations

Caution:

To prevent an incident of injury by not upholding the following

Before machining, check whether the machine is or isn´t mechanically or otherwise damaged.

Commission the machine only in case that the intake pressure hose is in no way

damaged.

The pressure hose and air connectors are to be regularly checked. In the case of

damage, have them immediately replaced at the service center which is authorized to perform

such repairs. Contact your supplier.

The machine has a so-called lower exhaust system via the cutting device. This solution has the

advantage of cooling the device and expulsion of chips and it is, however, necessary to pay

attention to a heightened awareness and wear protective glasses.

The chips may catapult out against your face.

Personal Protection Preventing Injury

Use protective glasses while working, firm work footwear, protect hearing, suitable head

cover, respectively a protective helmet.

Connect machine to pressurized air lines only in the case that the release valve of the

machine is in the off position.

Before each use, check whether the equipment or the pressurized air input is damaged.

Don´t use machine in the case it is damaged in any way.

Protect the machine from humidity and don´t use in a damp environment.

Ensure good lighting at the worksite so as to prevent risk of possible injury or damage

to sight.

Caution, the machine (milling cutter) is sharp, with a risk of the danger of injury. When

replacing, use protective gloves, never touch the milling cutter when it is in

motion.

The material machined must always be firmly attached and in a horizontal position.

The optimal height of a workpiece is 900mm above the ground.

Watch the intake hose while working; it should always freely lay on the floor away from

the material being worked on, or other sharp objects.

After finishing work, disconnect the equipment from the input of pressurized air.

Don´t overload the motor of the machine. The machine works best when it isn´t

overloaded.

Hold the equipment firmly in hand - palm while working.

Beware of danger from injury by hot metal shavings.

Important:

In case of damage, have the machine repaired at a service center which is authorized to

perform such repairs. Contact your supplier for more information.

11. Use

Important:

The equipment may only be used if it is fitted with blade plates that are equipped by our

supplier, respectively The maker of the equipment. These are 3-sided blade plates. The

equipment is fitted with 3X blade plates. It is strongly recommended to never use other than

original plates.

11.1 Setting the size of the cut

Caution:

When adjusting use work gloves and additional means of personal protection.

Operations must be performed with the machine at rest and upon disconnection

from lines of pressurized air.

Disconnect the machine from the input of pressurized air.

Loosen the arresting screw setting (pic.10.0.1 position D)

Turn the guide plate (pic.10.0.1 position E) for setting the size of the cut. The current

setting can be subtracted from the integrated scale. The scale is only orientational and

the resulting cut may differ.

Upon setting, again tighten the screw (pic.10.0.1 position D).

Important:

The maximum cut is 2mm wide (the spot height P pic.11.1.1). This cut must be attained via

several steps. It depends on the firmness of the material. We recommend performing a test.

Start with a smaller cut and gradually raise the value up to the moment that work with the

machine is still comfortable, and the plates retain the ability of a smooth cut without increased

vibrations.

We recommend starting a work journal in which it is possible to record the measured values

and your own procedure for machining.

pic. 11.1.1

Important:

The machine was made for manual de-burring. Precision machining depends on the

corresponding preparation of machined edges. Unfortunately the material is often

so-called underburned or undercut. This imprecision will also certainly appear in the

results of the machining.

Important:

If it is difficult to cut a workpiece in one step, we recommend dividing the process

into several chips. The reason may be excessive wear of the cutting plates or more

difficult machine-ability of the material.

11.2 Machining

Connect the machine to the lines of pressurized air and set the value on the pressure

regulator to 5 - 6bar. Upon setting the optimal values we recommend conducting a test.

Set the complementary greasing the the middle setting.

Upon careful setting of the first cut, see section 11.1, firmly grip the equipment, release

the safety on the release valve and commission the machine.

Set the machine upon the material so that the pressure/contact plate (pic. 10.0.1

position E) is in contact with the material in the maximal possible surface area.

Slowly move the machine to the material, and you will feel that the milling cutter is

coming into the range of the cut. Caution!!! At this moment a jerking motion may

occur, so be careful.

Move the machine further in the direction towards the material up to the point when

the milling cutter is sunken into the material at the full profile of the set chipper. The

contact sheave must now touch the edge of the workpiece. The pressure plate´s

surface must lie on the material.

Now you must initiate machining in the direction from left to right. Slide the machine

gradually and only at such speed as for the milling cutter to be able to smoothly

remove the material in the set profile of the chipper. Otherwise the milling cutter will be

pushed from the material and the cut will be uneven.
