4 IMPORTANT INSTRUCTION
•
The coring column must be fixed firmly and without play on the material to be worked.
•
For drilling above you with water cooling, always use a water collector. Otherwise water
may enter the electric circuit of the core drilling machine and constitute a danger for man
and machine. (The machine must always be connected via an earthed protection).
•
Use only diamond tools suitable for the material to be worked (do not use concrete drill
bits for wood, metal, etc.). Diamond drill bits that are not perfectly round cause extra load
on bearings and gears.
•
Work with care and concentration. Always avoid overloading.
•
Do not carry/carry the core drill by the power cord.
•
In the event of damage to the switch, cable, plug or housing, stop the machine
immediately.
•
Only put the machine into operation if the diamond drill can turn freely.
•
When replacing the diamond drill, always use a counter wrench (SW 32) for the core drill
head. Never use a hammer, because of the risk of damaging the sprockets.
•
Do not operate the machine for more than one minute without water supply. Otherwise,
the wear of the seals in the machine will increase considerably.
5 MAINTENANCE AND TROUBLESHOOTING
R
EMOVE THE PLUG FROM THE SOCKET BEFORE CARRYING OUT MAINTENANCE
OR CONTROL
.
Regularly clean the cooling grooves with compressed air. After 250 hours of operation,
replace the oil in the gearbox (80W90 max. 450 ml) and check the wear of the brushes of the
electric motor. If necessary, adjust the friction torque of the inner friction clutch (adjustment
torque see technical data). The above-mentioned interventions, as well as all other
electrotechnical repairs, are only reserved for a licensed professional (electrician). For
repairs/replacements, only use original Saint-Gobain Abrasives SA parts. The electrical part
must be checked regularly by a licensed professional electrician (about twice a year).
In the event of an oil or grease leak, take the machine out of service immediately. Oil or
grease leaks lead to a considerable increase in gear wear. The machine must be checked by
an authorized professional.
If water leaks from the spindle, take the machine out of service immediately. Leaking water
may enter the electrical circuit of the core drilling machine and pose a danger to man and
machine. The leak indicates poor condition of the seals. Have these gaskets replaced by a
licensed professional.
