2. Safety instr ctions
2.1 Care obligation of c stomer
The core drill grinding machine ERM.100/3 was designed and produced after giving due
consideration to danger analysis and after careful analysis of appropriate harmonized
standards, as well as the further technical specifications. t conforms to the status of the
latest technology and guarantees maximum possible safety.
However, the specified safety level can only be achieved if the necessary measures are
taken during operation. The care obligation of the customer includes planning these
measures and controlling their execution.
The customer must especially ensure that:
-The machine is used properly according to the specification (please refer chapter 1.
Production description)
-The machine should only be operated in faultless and functionally sound condition.
n particular the safety devices are to be checked for proper functioning regularly
-These original instructions need to be available in full and legible condition at the
location where the machine is operated.
-Personnel handling the machine need to be provided with adequate instructions on
work safety and environment protection on a regular basis. The operator needs to
have read and understood the operating instructions document and the safety
measures defined in them in particular.
-All the safety and warning signboards near the machine are not to be removed and
are maintained in readable condition.
2.2 Explanation of the sed safety signs
The following safety signs have been used in the present operating instructions document:
These signs are supposed to attract the attention of the reader to the text of the adjacent
safety instruction. These signs indicate that there is danger to the life and health of persons.
Use eye protection
Protection to eyes against
flying particles during the
grinding process
General danger
Please pull the power plug
out before replacing the disk
or changing the location of
the machine
Danger of laser rays

2.3 Basic safety meas res
Use eye protection
Wear protective glasses without exception
while performing grinding jobs with the
ERM.100/3. Dust from the grinding
operation can damage your eyes seriously.
Remove the grinding disk protection only
while replacing the grinding disk. Otherwise,
the protection should always be there on
the machine. The ERM.100/3 has a laser
beam generating device. Eyes should never
be exposed to the laser rays, as they may be
damaged seriously. Avoid exposing the
optical system directly to sunrays to avoid
the danger of fire.
Please pull the power plug out of the mains
socket before replacing the grinding disk or
changing the location of the machine.
Laser protection clauses: The laser source
corresponds to the Laser Protection Class
according to D N EN60825-1/94. No
additional protection measures are
therefore necessary.
2.4 Operating staff req irements
The machine should be operated only by staff who have read this operating instructions
manual, and who observe them in practice.
2.5 Special types of dangers
You must perform the following activities before each start up:
-Check the machine for visual damages and repair any identified defects immediately
-The machine should only be operated in faultless condition
Check electrical fittings regularly:
-Reattach or tighten loose connections
-Ask an electrician to replace damaged wires or cables without any delay
- Never clean electrical fittings with water or similar liquids
Modifications to the machine:
-For security reasons, do not make any modifications in the machine on your own.
-Use only original spare parts consumables and accessories as they are designed
specifically for the machine.

5.2 Adj sting and installing the machine
5.2.1 Replacing the index plate
The index plate of the core drill grinding machine determines the precision of the grinding of
core drills with various numbers of teeth.
As standard the machine is supplied including index plate 8/10 for use with cutters with 4, 5,
8 and 10 teeth. See chapter 7. Accessories for optionally available index plates.

Replacing the index plate
Select the appropriate index plate for your core drill. To replace the index plate turn the
knob in the clockwise direction until the grub screw in the index plate is facing upwards.
Tighten the edge screw (refer to Figure a). Turn the knob in anti-clockwise direction. Loosen
the grub screw (Allen key 2.5) and remove the index plate.
Inserting the index plate
Place the selected index plate on the shaft. Make sure one of the grooves on the side you
want to use is placed against the spring-loaded selector.
Tighten the grub screw lightly and turn the knob in the clockwise direction and tighten it.
Then fully tighten the grub screw on the index plate.

5.2.2 Aligning a core drill
While performing the adjustments, please note that the drill cutters are very
sharp and you can suffer physical injuries easily. Always wear safety gloves.
1) Set the core drill holder at 90 degrees.
2) Switch on the laser beam with the red button on top of the laser beam housing
3) Direct the laser beam with the help of the laser guidance rod to align it above one of
the teeth.
4) Rotate the core drill in the holder until the laser beam only just touches the tip of the
selected tooth.
