2 Safety Instructions

WARNING

Read all safety information and instructions supplied with the drill stand and drill or drive units. Failure to observe the safety instructions and precautions can cause serious injuries.

You must always comply with the currently valid version of the general accident prevention / health & safety regulations.

Keep all safety instructions and precautions for future reference.

2.1 Operating personnel requirements

a) People below the age of 18 may not use the unit.
b) Store drill stands out of the reach of children when not in use. Do not allow people to use the tool unless they are familiar with it, or if they have not read this instruction manual. Drill stands are dangerous if they are used by inexperienced people.
c) Always work carefully, attentively and sensibly when using this tool. Do not use the unit if you are tired or are under the influence of drugs, alcohol or medication. A moment of inattention while using the tool can result in serious injuries.

2.2 Workplace safety

a) Keep your work area clean and well illuminated.
Untidiness and unlit work areas can result in accidents.
b) Watch out for open and concealed electricity cables, and water and gas pipes. Use suitable detectors to find concealed utility pipes and cables, or contact the local utility company for advice.
Contact with electricity cables can cause fires and an electric shock. Damage to a gas pipe can cause an explosion. Penetrating a water pipe causes damage to property or could cause an electric shock.
c) Inform and consult the responsible structural engineer, architect or the responsible site engineer about planned drilling.
Cut through reinforcement only with the approval of a structural engineer.

2.3 Electrical safety

a) Before use, check all water-carrying parts – including those of the accessories – for perfect working order and leaks.
Leaking water increases the risk of an electric shock.

2.4 Safety of people

a) Wear personal protective equipment and always wear goggles.
The wearing of personal protective equipment, such as dust mask, non-slip safety shoes, helmet or ear protectors, depending on the type and application of the power tools, reduces the risk of injuries.
b) Avoid abnormal postures when working. Ensure you are standing firmly and maintain your balance at all times.
This will enable you to control the tool better in unexpected situations.
c) Wear suitable clothing. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.
Loose clothing, jewellery and long hair can get caught in moving parts.
d) If dust extraction and collection devices can be installed, ensure that these are connected and are used correctly.
Use of a dust/water extraction system can reduce hazards caused by dust.
e) Don't be lulled into a false sense of safety and do not break the safety rules for drill stands even if, after much use, you are familiar with the drill stand.
Careless action can cause severe injuries within fractions of a second.
f) When carrying out drilling work that requires the use of water, route the water away from the work area or use a liquid collection device.
Such precautions keep the work area dry and reduce the risk of an electric shock.

2.5 Using and handling the drill stand

a) Before mounting the drill or drive unit, set up the drill stand correctly in accordance with these instructions. Correct assembly is important to ensure proper, faultless functioning of the stand.

EN

b) Fasten the drill stand securely on a firm, flat surface using the specified and undamaged installation materials.

If the drill stand can slip or wobble, the drill or drive unit cannot be guided uniformly and safely.

c) Disconnect the plug of the drill or drive unit from the socket before mounting the drill or drive unit on the drill stand, make any unit settings or change accessory parts.

Unintentional starting of drills or drive units causes accidents.

d) Fix the drill or drive unit securely onto the drill stand as specified before starting work.

Slipping of the drill or drive unit on the drill stand can cause loss of control and injuries.

e) Remove all setting tools, spanners and installation materials not required before switching on the drill or drive unit.

Setting tools, spanners and installation materials located in/on a rotating part of the tool can result in injuries.

f) Do not overload the drill stand and do not use it as a ladder or scaffolding.

Overloading or standing on the drill stand can cause the centre of gravity of the drill stand to move upwards and the drill stand overturns.

g) Keep the handles and gripping surfaces dry, clean and free from oil and grease.

Slippery handles and gripping surfaces prevent safe operation and control of the drill stand in unforeseen situations.

h) When fixing the drill stand on the workpiece using anchors and screws, ensure that the anchoring used is able to hold the machine safely during use.

If the workpiece is not resistant or is porous, the anchor can be pulled out, which causes the drill stand to detach from the workpiece.

i) If fixing the drill stand on the workpiece by means of a vacuum plate, ensure that the surface is smooth, clean and not porous.

Do not fix the drill stand onto laminated surfaces, such as tiles and facings of composite materials.

If the surface of the workpiece is not smooth, flat or adequately fixed, the vacuum plate can detach from the workpiece.

NOTE

The above safety instruction only applies if it is planned to use the tool with a vacuum plate.

j) Before and while drilling, ensure that the vacuum is sufficient.

If the vacuum is insufficient, the vacuum plate can detach from the workpiece.

NOTE

The above safety instruction only applies if it is planned to use the tool with a vacuum plate.

k) Never carry out overhead drilling and drilling, if the drill stand is fixed on the machine by means of a vacuum plate only.

In the event of loss of vacuum, the vacuum plate detaches from the workpiece.

NOTE

The above safety instruction only applies if it is planned to use the tool with a vacuum plate.

Use RAWL anchors with diameter 20 mm / M12 for fixing onto walls.

I) Do not use any accessories that have not been especially provided and recommended for this drill stand by the manufacturer.

Just because you can attach accessories to your drill stand is not a guarantee of safe use.

m) Additional signs or other, non-BAIER-specific parts must not be screwed or riveted onto the drill stand.

This could damage the drill stand and cause malfunctions to occur.

n) Note and follow all safety and work instructions for the accessories used.

o) Never place the feed crank handle on the hexagon of the tapered shaft to tighten it.

Excessive torques could damage it.

2.5.1 Service / Maintenance / Repair

a) Maintain the unit with care in accordance with the stipulations of the instruction manual. Check whether moving unit parts are in proper working order and do not jam, whether parts are broken or damaged in such a way that they impair the function of the unit. Many accidents are caused by poorly maintained tools and accessories.
b) Repair and maintenance work may only be carried out by an authorised service centre of OTTO BAIER GmbH. Otherwise, all liability and warranty claims against OTTO BAIER GmbH expire.
c) Ensure that original BAIER spare parts and original BAIER accessories only are used when needed. Original parts are available from authorised dealers. Use of non original parts can cause damage to the machine and an increased risk of accidents.

2.5.2 Explanation of the pictograms on the drill stand
