Safety instructions

The Virax 162120 threading machine is an electro-mechanical machine which presents certain

hazards. It is therefore important to obey the following instructions to avoid causing yourself or

others possible serious injuries or lesions.

General safety instructions

Choice of tool

Use a suitable tool. Do not use low-power adaptable tools or devices for carrying out heavy work.

Do not use tools for purposes other than those for which they have been designed.

Maintenance and storage

Store your tools in a safe place. Unused tools must be stored in a dry, closed location out of the

reach of children.

Maintain your tools carefully. Maintain your own tools so that you can work better and in greater

safety. Observe maintenance indications as well as those relating to the changing of accessories.

Keep handles dry and free of oil and grease.

Check whether the tool is damaged. Before using the tool, always carefully check that all the

parts are operating correctly. Check that the parts move correctly, that they do not seize and that

other parts are not damaged. All the components must be installed correctly and full the

conditions needed to ensure that the tool is in perfect working order. All safety devices, switches

or other damaged or defective parts must be appropriately repaired or replaced by a qualied

technician.

Warning! Be sure to use the tool and its accessories in accordance with the safety instructions.

Consider the range of options for the tool taking into account the working conditions and the task

to be carried out. It can be dangerous to use the tool for tasks for which it is not intended.

This tool complies with current safety regulations. All repairs must be carried out by qualied

professionals using original spare parts, failing which the tool may become dangerous to use

and the warranty will be nullied.

Safety instructions for the user

Keep children away. Do not allow other people to touch the tool; keep them away from your

working area.

Wear appropriate working clothes. Do not wear loose clothing or jewellery; they could be caught

in the moving parts.

When working in the open air, you are recommended to wear rubber gloves and shoes with

nonslip soles. If you have long hair, tie it back with a hair net.

Do not increase your range. Avoid adopting a posture which you nd tiring; make sure you have

a rm footing and always maintain your balance.

Always concentrate. Look at your work, use your common sense and do not use the tool when

you are tired.

–

Safety instructions relating to the work area

Keep your work area tidy. Untidiness increases the risk of an accident.

Take into account the environment around your work area. Do not expose electric power tools to

the rain. Do not use electric power tools in a damp or wet environment.

Make sure the work area is well lit. Do not use electric power tools in the neighbourhood of

inammable liquids or gases.

Prohibited uses

The machine is not intended for tightening or loosening joints.

You may be tempted to use the power of the machine for tightening or loosening joints. Doing

this is prohibited as the force of the motor is much greater than the force exerted by the hand

holding the joint whether directly or using a spanner. When loosening, you risk fracturing your

hand or forearm or having the spanner thrown at you or one of your colleagues. (Moreover, when

loosening, if the joint has not been released, you will subject the motor to a force which may

damage it.)

The machine is not a winch.

You may be tempted to use the force of the motor to raise or lower loads. This use is prohibited

as the machine could topple over and jettison its load. (Moreover, you may damage the motor).

The machine is not intended for coating the threads with sealing paste.

As the paste is naturally applied by hand, this exposes the operator to the risk of being cut.

Important: Virax may in no respect be held liable for accidents which occur arising from the

machine being used for purposes other than those for which it was intended.

Do not use tools other than those designed for use with the machine.

Only the cutting, reaming and threading tools designed for the machine may be mounted on the

machine.

Important: Virax may in no respect be held liable for accidents which occur arising from the use

of tools other than those specically intended for use with the 162120.

Handling and working instructions

Transporting the machine

The machine weighs about 60 kg. So two people are needed to carry it. Two handles

are provided at either end of the frame for this purpose.

To move the machine using a hoist or crane, proceed as indicated in page 14.

In addition, a trolley has been especially designed for transporting the machine.

(This is described on page 15).

–

Instructions relating to the machine electrical power supply.

The machine must be provided with a 230V electrical power supply.

The plug and any extension lead must have a grounding pin connected to a ground

connection in the workshop.

Do not pull the machine by its power cable. (This is not a rope!). Likewise, do not

disconnect the machine by pulling on the cable.

–

Instructions relating to your protection and the protection of those around you

It is essential to place the tube on one or more pipe holders, also called benches. (Virax part

numbers: pipe holder without feet: 161100 ; pipe holder with feet: 161110).

If the free length of the tube behind the machine is too long (typically more than 1m empty), you

risk the tube starting to oscillate (which you may not realize in time as your attention will be on

the tube being machined) which then causes the machine to become unstable causing it to

topple towards you.

–

Do not wear a tie, scarf, pendants, loose clothing, chain bracelets, rings etc.

or wear your hair long... any of which could be caught by the rotating parts of the

machine.

–

Wearprotectivegoggles toprotectyour eyesfrom oilspatter and,most importantly,

from any metal turnings which are thrown up. In the case of oil spatter, wash your

eyes copiously with water and consult an ophthalmic doctor if you experience any

problems with your vision. If a metal turning is thrown up, do not try to remove it or

have it removed by anyone else but consult a specialist service immediately.

–

It is essential to wear a helmet with ear defenders.

In compliance with standard EN 61029-1 (refer to the standard published in your

language) and standard ISO 3744, laboratory tests have given the following

results:

Acoustic power level: LwA = 92 dB(A)

Acoustic pressure at the user’s ears: LpA = 84 dB(A)

LpMaxPeak < 130 db(C)

–

Be careful not to cut yourself on contact with sharp items, in particular: cutter

wheel, thread dies, reaming cone, internal edges of the tube.

–

Wear gloves for handling metal turnings: these can cause bad, ne and deep

cuts.

Wear gloves if you are allergic to lubrication oil.

–

Pay attention to crushing hazards, in particular when lowering the tube cutter, the

die head or the reamer and when the saddle is moving.

–

Wait for the motor to stop before carrying out any work.

Disconnect the machine when carrying out assembling, dismantling and cleaning

operations in order to guard against the risks of the machine being accidentally

started up: you or one of your work colleagues could accidentally step on the control

pedal or press the start button while your hands are in the machine.

Warning: The machine is protected against accidental starting by a relay. After the

electrical power is cut, you can only start the machine by pressing the start button.

You must not under any circumstances short circuit the start button under the

pretext of «helping you with your work».

Likewise, you must not use a machine whose start or stop button is not

working.
