3.5 First use 

WARNING! 

Staff and equipment may be endangered if the drilling machine is first used by unexpert 

staff. We do not take responsibility for damage caused by incorrect commissioning. 

Power supply 

Connect the main plug of the drilling machine to the power supply. 

Check the fuse protection of your power supply to the technical data for the power consumption 

of the engine. 

ATTENTION! 

Please pay attention that all three phases (L1, L2, L3) for 400V - drilling machines are 

connected correctly. 

Most engine failures result from incorrect connection, for instance the neutral connector 

(N) is being connected to a phase. 

This might lead to the following results: 

• The engine does get quickly very hot. 

• The engine noise increases, i. e. becomes louder. 

• The engine has no power. 

When the phases are connected incorrectly, the guarantee is null and void. 

ATTENTION! 

Drilling machines with frequency converter should not be operated with a CEE plug. Connect 

the machine permanently to a connection box (see EN 50178/5.2.11.1) 

INFORMATION 

The frequency converter (driving regulator) might release the FI protected switch of your electrical 

supply. In order to avoid any malfunctioning, you either need an FI protected switch sensitive 

for pulse current or and AC / DC sensitive one. 

In case of a malfunction or release of the FI protected switch, please check the type installed. 

The following signs indicate if you have one of the FI protected switches described above. 

FI protected switch sensitive to pulse current 

FI protected switch sensitive to AC/DC 

Typ A 

Typ B 

300 mA 300 mA 

© 2007 

We recommend you to use an FI protected switch sensitive to AC/DC. FI protected switches 

sensitive to AC/DC (RCCB, type B are adequate for 1 phase and 3 phase fed frequency converters 

(driving regulators). 

An FI protected switch type AC (only for alternating current (AC)) is not appropriate for frequency 

converters. FI protected switches type AC are no longer used.

4.5.2 Disassembly of the drill chuck 

4.6 Cooling 

WARNING! 

Disassemble the drill chuck only when the drilling machine is disconnected from the 

electrical power supply. 

Disconnect the drilling machine from the electrical power supply. 

The conical connection can be separated with a plastic or a rubber hammer. 

The friction generated during rotation can cause the edge of the tool to become very hot. 

The tool should be cooled during the drilling process. Cooling the tool with a suitable cooling 

lubricant ensures better working results and a longer edge life of the tools. 

This is best realized by a separate cooling equipment. If there is no cooling equipment included 

in the delivery volume, you can cool by means of a spray gun or a washing bottle. 

ATTENTION! 

Danger of injury due to brushes getting caught or pulled in. 

Use a spray gun or a washing bottle for cooling. 

INFORMATION 

Use a water-soluble and non-polluant drilling emulsion which can be obtained from authorized 

distributors. 

Make sure that the cooling agent is being collected. 

Respect the environment when disposing any lubricants and cooling agents. 

Follow the manufacturer’s disposal instructions. 

4.7 Before starting the working process 

Before you start working, select the required speed. It is depending on the drilling diameter and 

on the material used. 


© 2007 GB

Handling 



„Speed table“ on page 27 

WARNING! 

For drilling jobs, it is necessary to clamp the workpiece firmly to prevent the bit catching 

on the piece. Example of suitable clamping devices include a machine vice or clamping 

jaws. 

Put a wooden or plastic board beneath the workpiece to avoid drilling through to the work table, 

vice, etc. 

If necessary, adjust the required drill depth by means of the drill depth stop in order to achieve a 

constant result. 

Use a dust remover unit while working with wood. Sawdust can be health hazardous. Also use a 

suitable protective mask for any work which generates dust. 

4.8 During the working process 

The spindle sleeve feed is being performed by the star grip. Make sure that the feed is being at 

a regular pace and not too fast. 

The reset of the spindle sleeve is being performed by a track recoil spring. 

WARNING! 

Danger of clothing and / or long hair getting caught. 

• Make sure to wear a well-fitting work suit during drilling work. 

• Do not use gloves. 

• If necessary, wear a hairnet. 

ATTENTION! 

Danger of collision by the levers of the star grip. 

Do not let the star grip get loose when resetting the drill sleeve. 

Thin bits break easily. 

In case of deep drilling, remove the bit from time to time, to remove drilling chips from the bore 

hole. Some drops of oil reduce friction and ensure a longer edge life of the bit. 

CAUTION! 

Danger of crushing! Do not place your hand between the drill head and the spindle 

sleeve.

Malfunctions 



Malfunction 

Cause/ 

possible effects 

Solution 

The temperature of the 

spindle bearing is too 

high 

Ratteling of the working 

spindle when working 

with rough workpiece 

surfaces 

• The bearings are worn out 

• The pretension of the bearings is 

too high 

• Working with high drilling revolutions 

for a long period of time 

• Clearance of the bearing too 

wide 

• The working spindle moves up 

and down 

• The adjusting gib has come loose 

• Clamping chuck is loose 

• Tool is blunt 

• Workpiece is loose 

• Replace 

• Reduce clearance in the bearing 

for (taper roller bearings) 

• Reduce drilling revolutions / feed
