INFORMATION
This numeric value had been measured on a new machine under conventional operating conditions. Depending on the age or wear of the machine, the noise behavior of the machine might
change.
Furthermore, the extent of the noise emission is also depending on manufacturing
influence factors, such as speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is an emission level and not necessarily a safe
working level.
Unless the degree of noise emission and the degree of noise disturbance are depending on one
another it is not possible to use it in ord er to reliably determine if it is necessary to take further
preventive measures or not.
The following factors influence the actual degree of the noise disturbance of the
operator:
• Characteristics of the working chamber, e.g. size or damping behavior,
• Other noise sources, e.g. the number of machines,

lified personnel.
We do not take responsibility for damage caused by incorrect commissioning.
ATTENTION!
OPTIMUM
MASCHINEN - GERMANY
The geared drill will be delivered without operating material (oil, coolant). First fill in oil
and coolant.
„Lubricant table“ on page 45
3.5.1 Power supply
Connect the main electrical power.
Use the technical information regarding the total connection rate of the machine.
ATTENTION!
Imperatively make sure that all 3 phases (L1, L2, L3) are connected correctly.
Most of the defects on motors are resulting from wrong connections. For instance, if a
motor phase is not correctly clamped or connected to the neutral conductor (N)
This may cause:
• That the motor is becoming hot very rapidly
• Increased motor noises.
• The motor has no power.
ATTENTION!
Make sure that the direction of rotation of the drive motor is correct. If the rotational
direction switch is switched to the position to perform clockwise rotations (R) the drill
spindle needs to rotate clockwise. If necessary, exchange two phase connections.
If your connector plug is equipped with a phase inverter, this is done by turning it by
180°.
If the machine is incorrectly connected the warrantee will become null and void.

4.7 Working with the machine
4.7.1 Preparation
WARNING!
During drilling work you must secure the piece to be drilled firmly, in order to ensure that
it is not moved by the bit. Examples of a suitable securing tool include a part-holder bolt
or securing clamps.
Put a wooden or plastic board beneath the piece so that you do not drill through to the work
table or the part-holder bolt.
If necessary, adjust the required drilling depth using the depth stop to obtain a constant result.
Make sure to use a dust collection unit when working with wood, as sawdust can be a health
hazard.
Use a suitable protective mask for any work that generates dust.
First, select the speed of the bit. This will depend on the diameter of the bit being used and
the material.

5.3 Examples to calculatory determine the required speed for your drilling
machine
The necessary speed is depending on the diameter of the drill bit, on the material which is being
machined as well as on the cutting material of the drill bit.
Material which needs to be drilled: St37
Cutting material (drill bit): HSS spiral bit
Set point of the cutting speed [
v
] according to the table: 40 meters per minute
c
Diameter [d] of your drill bit: 30 mm = 0.03 m [meters]
Selected infeed [f] according to the table: about 0.35 mm/rev
Speed
Set a speed on your drilling machine which is less than the determined speed.
INFORMATION
In order to facilitate the production of larger drill holes they need to be pre-drilled. This way, you
reduce the cutting forces and improve the guiding of the drill bit.
The pre-drilling diameter is depending on the length of the
chisel edge. The chisel edge does not cut, but it squeezes
the material. The chisel edge is positioned at an angle of 55°
to the major cutting edge.
As a general rule of thumb it applies: The pre-drilling
diameter is depending on the length of the chisel edge.
Recommended working steps for a drilling diameter of 30 mm
2014
US
Example:
1st working step: Pre-drilling with Ø 5 mm (0.2").
2nd working step: Pre-drilling with Ø 15 mm (0.6").
3rd working step: Drilling with Ø 30 mm (1.2").

ATTENTION!
Properly-performed regular maintenance is an essential prerequisite for
• safe operation,
• fault-free operation,
• long service life of the machine and
• the quality of the products you manufacture.
Installations and equipment of other manufacturers must also be in optimum condition.
ENVIRONMENTAL PROTECTION
During work on the drilling head, make sure that
• collector vessels are used, with sufficient capacity for the amount of liquid to be collected.
• Liquid and oils are not spilt on the ground.
Clean up any liquid or oils immediately using proper oil-absorption methods and dispose of them
in accordance with current legal requirements on the environment.
Cleaning up spills
Do not re-introduce liquids spilt outside the system during repair or as a result of leakage from
the reserve tank: collect them in a collecting vessel to be disposed of.
Disposal
Never dump oil or other pollutant substances in water inlets, rivers or channels.
