English
• Remove the pieces of the core as
described in paragraph 11. Start boring
again. If the vibration recurs, check the
machine mounting (see above).
Excessive drill wear
• If the water flow and pressure are
inadequate: use maximum flow for drill
cooling and lubrication.
• If using recycled water loaded with
abrasive material: use pure or decanted
water.
• If too much pressure is applied, the
diamonds will become detached causing
accelerated wear: reduce the boring
pressure.
• If the material to be bored is too abrasive:
use a special drill. Contact your supplier.
No progress
• Stop the motor immediately.
• Check the water flow.
• Remove the drill and check for wear or
polishing or that a part of the diamond
tipped strip has not become unwelded
and is turning with the drill at the base of
the hole.
If this happens, break and remove the
core (if the core has stayed in the hole -
see paragraph 11). Recover all the
diamond tipped segments and unscrew
the damaged drill for repair if possible.
Start boring again with a new drill.
If the segments cannot be recovered,
overbore.
• If the drill has wandered due to bad
centring, move the axis slightly or bore
with a larger drill (on the same axis).
• If there is a buried steel girder (100%
steel boring), a wooden joist (expanding
and jamming) or an elastic material
(rubber), bore in another place.

Item number
Quantity
For rapid delivery of spares and in order to
avoid any wasted time, it is necessary to
remind your supplier of the details shown
on the instruction plate on the machine with
each order, as well as the reference of the
part to be replaced.
• Clutch :
The geared motor has a mechanical
clutch which disengages to protect the
user only when the drill jams during
boring.

Using the geared motor
- Check the mixture for petrol engines.
It should be a 5% mixture with 100%
synthetic oil for 2-stroke engines.
• - for pneumatic engines check the
pressure (approx. 6 bars) and the flow
rate (50l/s).
• Speed changes
Operate the gear change knobs only
when the motor is fully stopped and
turn the shaft by hand to align the
pinions.
17
Repairs
• Retighten all nuts and bolts regularly.
• Check that the motor mounting surfaces,
the guides.
19
Scrapping
• Main materials :
Motor :
- Aluminium (AL) - Steel (AC),
Copper (CU) - Polyamide (PA)
Machine :
- Aluminium (AL) - Steel (AC),
Polyacetal (PA)
Never use pliers or other tools to
change speed.
In the event of deterioration and
scrapping of the machine, the
following items must be disposed
of in accordance with the
requirements of the legislation in
force.
The manufacturer declines all
responsibility for loss or damage
resulting from misuse or any
modification, alteration or
powering that does not conform
to the manufacturer's original
specifications.
At the work station, the sound
pressure level may exceed 85 db
(A)
In this case individual protection
measures must be taken.
