SAFETY
2.3 General safety advices
Warning signs and stickers on the machine, which are illegible or removed, have to be replaced
immediately!
The following recommendations are NECESSARY to avoid malfunctions, damages, and health
impairments:
The working space and the floor around the machine have to be
free
of oil, grease and material tailings!
Look after a sufficient illuminated and cleaned working space!
Don’t use the machine outside!
For your own safety it’s forbidden to use the machine if you’re tired,
distracted or if you took any medicine, alcohol or drugs!
Climbing on the machine is forbidden!
Serious injures caused by falling of or tilting of the machine are
possible!
The drilling machine is only allowed to be operated by skilled workers.
Unauthorized and unskilled persons, especially children, should
maintain a safety distance to the machine!
While working on the machine, don’t wear any loose jewellery, wide
clothes or loose hair.
Loose objects might get caught by the rotating drill bit and so
cause injuries!
Wear suitable protection clothing (protection gloves, protective
goggles, eae protection,…) while working on the machine!
Never let the running machine unattended! Before leaving the
workplace turn off the machine and wait until the drill stops!
10

SECURITE
Before performing maintenance or setting changes the machine has to
be disconnected from the electricity supply! Before disconnecting from
the electricity supply you have to turn the main circuit breaker off.
Never use the power cord for transportation or to manipulate the
machine!
Always fix the work piece with a suitable tool. Never fix the work
piece with your hand!
Heavy injuries to your hand caused by sharp edges are possible, while
the work piece is rotating because of the drill are possible.
Remove the chips only with a hand brush, a brush or a swarf hook.
Never remove the chips with your hand or blow them away!
Don’t use damaged drills or damaged work pieces!
The tool change should be carried out only when the drill is stagnated!
Withdraw the drill chuck key before starting the machine!
Check the precautionary measures and the components for
damages before the start-up!
Don’t remove any mechanical or electrical precautionary measures!
2.4 Autocollants d‘avertissements
This sticker remembers the worker to read the users manual before
starting the work and to familiarize oneself with the machine.
This sticker refers to the electrical converter of the machine.
Before opening the casing cover, the electricity supply has to be
effectively disconnected. Pull out the power plug!
11

SAFETY
2.5 Remaining risk
Keep in mind these remaining risks even if you observe the precautionary measure and the
flawless employment:
• Risk of injury of hands and fingers caused by the rotating drill
• Risk of injury caused by sharp edges of the work piece, especially if you don’t fix
it correctly.
• Loose Hairs and wide clothes might get caught by the rotating drill! Heavy risk of injury!
Precautionary measures have to be observed!
• Risk of injury caused by the contact with energized components
• Risk of cuts, if the borehole isn’t deburred.
• Risk of injuries caused by flying pieces even if you wear protective goggles.
(the protector minimizes the risk)
These risks can be minimized, when all precautionary measures are observed, the machine is
correctly maintained, neat and only used by skilled workers.

ASSEMBLY
3 ASSEMBLY
3.1 Scope of delivery/Workplace
After receipt of the delivery, look if all parts are present and in working order:
• drilling machine
• power cable with converter
• compressed air hose
• workpiece holder
• socket wrench
The workplace
Choose a suitable place for the machine.
Observe the safety requirements of Chapter 2 and the dimensions of the machine from
Chapter 1.
The selected location has to ensure an appropriate connection to the electrical grid
and to a compressed air supply
13

ASSEMBLY
3.2 Electrical connection
ATTENTION
Working at a not earthed machine:
Heavy injuries caused by a current pulse in case of a
malfunction are possible!
For this reason, you have to observe:
The machine has to be earthed and powered by earthed
plug socket.
• Check, if the needed voltage corresponds with the voltage of the local
power supply system!
• Too high tensions can cause critical injuries.
• The use of a source of power with higher or lower voltage can lead to serious
damages to the engine.
• The electrical connection of the machine is designed for the operation with
earthed plug sockets!
• The plug has to be connected with correctly installed and earthed plug sockets!
• It‘s not allowed to change the provided plug! If the plug doesn‘t fit or is damaged;
the electrical engineer is the only one authorized to replace it!
• In case of a repair or exchange it’s not allowed to connect the grounding connector with
a tensioned plug socket!
• Check with a skilled electrician or service technician if the grounding connector
instructions are understandable and if the machine is earthed!
• Damaged cables have to be removed immediately!
Extension cable
Make sure that the extension lead is in a good condition and suitable for power transmission.
An undersized cable can minimize the power transmition and will heat up. The following table

ASSEMBLY
3.4 Work preparation
• Use the drilling machine only if it’s correctly installed and if you read the user’s manual.
• Make sure that the protector of the machine is closed and secured before turning on.
• Check if the drill is correctly installed and not damaged before turning on.
• Check if the drill is suitable for the material and work.
• Never drill without checking, if the work piece is sufficiently fastened.

WARNING
All setting changes etc. only after separation of the machine
from the power supply!
4.1 Adjusting of the rotational speed and cutting rate
The cutting rate is conditioned by the rotational speed of the drill spindle and the drill diameter.
The correct choice of the feed and the rotational speed is crucial for the service life of drills.
Set appropriate speed:

BETRIEB
5.2 Drill selection
Depending on material and property there are three drill types with different lead angles.
(DIN 1414).
Type N is used for normal materials, type H for brittle materials and type W for soft materials.
Besides, you can arrange the drills in shank drills and Konsubohrer.
Shank drills are fixed in the drill chucks, while Konusbohrer can be directly inserted in spindles.
