Normal Operation
Guards:
Take measures to ensure that the machine can only be operated in a safe and functional
condition. Only operate the machine when all guards and safety-related devices such as
- detachable guards, emergency stop system, sound insulation, suction device etc.
are present and in working order. Always work with all available protection devices!
Workpiece:
Before machining, inspect the workpiece for foreign inclusions, knots, twists, objects
and other irregularities.
Working area:
An obstacle-free work area around the machine is essential for safe operation.
The floor should be level, well maintained and free from debris such as chips and cut-off workpieces.
Rotation speed:
The speed must correspond to the drilling bit and the respective operation.
Do not start drilling before the motor has reached full speed.
Drilling range during operation:
Never attempt to remove splinters, chips or other parts from the cutting
area while the machine is running! Never remove splinters and chips by hand!
- Clamp the drilling bit as deep as possible
Special tools:
For certain operating phases and operations it is necessary to use special tools, e.g. work-
piece stop, frame stop, mitre fence and dowel drilling unit.
Single pieces / samples:
Always use all protective devices and appropriate tools!
Workpiece machining:
Only process workpieces that can be safely placed and clamped on the table top.
Workpiece clamping:
The eccentric clamp or the optional pneumatic safety clamping cylinder must be used
for all drilling work. The eccentric clamp or the optional pneumatic safety clamping cylinder must be
clamped as close to the bore as possible.
Clamping round workpieces:
Attach a template with guide trough to the machine table; clamp and ma-
chine the workpiece. When using pneumatic safety clamping cylinders, set the smallest possible stroke.
Clamping long workpieces:
For the safe support of long workpieces, the appropriate equipment (e.g. sup-
port facilities such as roller blocks or table extensions) must be used for all drilling work.
Drilling depth / mortise length:
Only set the drilling depth and mortise length when the tool is stationary
and use suitable measuring equipment.
Extraction:
The machine must be connected to an effective extraction system. This requires a flow velocity
of at least 20 m/s for dry chips and 28 m/s for moist chips (moist 18 % or more).
Machine condition:
Check the machine for externally visible damage and defects at least once per shift!
Any changes that have occurred (including those in the operating behaviour) must be reported immedi-
ately to the responsible office or person! If necessary, stop and secure the machine immediately!
Damage:
Damaged parts must be replaced immediately. Repair work may only be carried out by author-
ised specialists and with the main switch locked.
Motor braking time:
The machine is equipped with a mechanical motor brake. If the drilling spindle does
not come to a standstill within the prescribed braking time (10 sec.) despite the brake being adjusted (re-
fer to section
15.4) the customer service must be contacted
.
Work interruptions:
Switch off the machine even during short interruptions! Never leave the machine
running unattended!
