Noise emission values in accordance with the DIN
EN 60745-1 standard:
Vibrations:
Note:
The measured values listed above depend on the
materials and operating procedures used and may
therefore be exceeded under other operating
conditions.
Using the machine to create bevels with a width
greater than that permitted will result in a
disproportionally large reduction in the machine’s
on-time and the service life of the indexable carbide
inserts. The vibration and noise emission values
will increase accordingly.
To prevent overloading the machine and to avoid
operator fatigue it is very important to observe the
maximum power-on periods especially when
machining wide bevels or high-strength materials.

K = 1,5 m/s²
Power-on time (POT):
To avoid damaging the machine, it is essential to
be monitor how long the machine has been
operating continuously (‘power-on time’).
All electric brushed motors generate large amounts
of heat in the rotor and stator. Although the machine
is fitted with a fan cooler that dissipates the heat
produced, if the machine is subjected to extreme
loads (e.g. milling large bevels, very hard or tough
materials) and/or is run continuously for a long
period of time, the cooling system may not be able to
cope with the amount of heat generated. If the
operator continues to use the machine, the rotor
(armature) may overheat to such an extent that the
winding insulation melts causing a short circuit.
(C=bevel width, POT=power-on time)
The power-on time is always expressed as a
percentage of one hour.
Example:
If the power-on time is specified as 50 %, then you
can use the machine to mill bevels for a maximum of
30 min. in an hour and must then leave the machine
to cool for 30 min.. If the machine is subjected to
heavy loads, the power-on time might be 20 %,
which means it can be used for 12 min. in any hour
and must be left to cool for 48 min.. Before
completely switching off the machine, we
recommend running the machine for one or two
minutes in idle mode (unloaded) so that fan can
continue to draw cool air through the machine.
Do not overload the machine!
The machine can become overloaded if, for
example, it continues to be used even though the
bevel being cut is too large for the material being
milled, or if the cutting inserts have become blunt
and therefore unable to penetrate the material.
Such conditions can lead to large machine vibrations
or even machine breakdown if the armature in the
motor is bent to such an extent that the rotor and
stator rub against each other, overloading the
windings and blowing the motor.
To prevent this sort of damage when milling large
bevels and/or hard materials, never try to machine
the bevel in a single pass, always use multiple
passes, and do not forget to change the carbide
inserts before they become blunt or worn.

Setting the bevel length:
The bevel length (a) is setting by adjusting the position
of guiding plate (1). The height setting can be read out at
the main scale (2) and the vernier collar (3). Loosen the
clamping lever (4) and rotate the guiding plate (1) until
the required bevel length has been set as shown by the
main scale (2) in combination with the verniere scale on
the collar (3). Retighten the clamping lever (4).
Once the bevel height has been set, a bevel should be
milled on a test sample to check whether further height
adjustments are required. These may be necessary
because the precision of the scale is approx. ± 1 mm.
The values above are experical values, no guarantee
values!
Some materials can harden on the edges of the
workpiece when working with flame cutting, plasma,
laser cutting. This can result in significant deviations
from the specified reference values.

ing plate. The lateral position of the radius on the work-
piece end face is determined by the guiding roll fitted and
cannot be altered.
Guiding plate set too low (radius incomplete).
Guiding plate set to high (radius cuts into material).
Guiding plate set correctly (radius fully formed with
smooth transition to workpiece surfaces.)

Operating mode
General:
Two-handed operation:
Whatever the position of the
machine, always use two hands to
control the machine.
When working with the machine, make sure that the
machine is always held with two hands (see red arrows)
and in such a way that both hands are kept away from
the machining point.
Ensure that the workpiece is securely clamped!
• for safety reasons
• to improve the service life of the
carbide inserts
• to prevent damage to the milling
machine
Important!
Before machining a workpiece, make sure that it is
securely clamped so that it cannot slip.
This should be done to ensure safe working so that the
workpiece does not slip or even fly off when being milled
and to prevent unnecessary vibrations in the workpiece
material.
The less vibration generated in the workpiece, the longer
the service life of the carbide inserts.
To became acquainted with the
machine, you must start by
machining a small bevel with a width
of no more than 2 mm and remember
to advance the machine slowly first.
Bevels of maximum width can only
be machined safely and reliably
once you have become used to
handling the machine.
Handling:
Damages caused by wrong power
supply!
• Check the supply voltage. The supply
voltage must correspondend with the
specifications on the type plate of the
machine.
Improper use can cause serious
injury!
• Make sure you always have a firm
footing when working with the
machine!
• Never touch the milling head when the
machine is running!
• Always lead the machine away from
body during working, never use the
machine above head height.
Risk of damage to equipment and
property!
• Working with worn or damaged
carbide inserts or milling heads will
cause the machine to fail!
• Avoid collisions when working with the
machine!
Working with the machine:
Press on-/off-switch (1) until it clicks into place!
Motor starts
Bring the machine slowly into
contact with the workpiece only
after the selected tool speed has
been reached.
Machining the workpiece (up-cut milling)
When milling a bevel always move the machine from left
to right against the direction of rotation of the milling head
(up-cut milling).
Switching off the machine
• remove the machine from the workpiece.
• press the on-/off-switch.
• once the motor is switched off, wait for it to come to a
standstill before placing the machine down on a
surface.

Maintenance
Before serving the machine always
disconnect the machine from the power
supply by removing the power cable
from the socket !
Repair must only be carried out by a
GERIMA trained technician!
Improperly repaired machines are
hazzard!
• Increased risk of injury
• Machine does not function correctly!
Hot carbide inserts and milling head!
• Burn hazzard!
• Wear protective gloves when replacing
the carbide inserts!
Maintenance plan:
Blunt tool can cause damage!
• Blunt tool can overload the machine!
• Inspect milling tools regulary for signs of
wear.
• Wear protective gloves when changing or
readjusting the carbide inserts!

Service 1:
To ensure that the machine can be cooled properly, the
ventilation slots must be kept clean. To avoid damaging
the motor winding it is important that no foreign matter
(e.g. chips) enter the motor compartment. Clean the
motor compartment regularly by blowing compressed air
through it.
Service 2:
Remove the screw for height clamping, lift the guiding
plate unit, clean the mounting thread, lubricate the thread
with teflon spray and then re-assemble in reverse order.
Disposal of components removed from the machine:
All machine parts, operating and auxiliary materials must be disposed of in accordance with
the applicable statutory provisions.
