Before Starting Work
To ensure safe working with the dry diamond drilling
systems, the following points must always be
observed before each use:
•
Read through all safety instructions and
warnings in this instruction manual.
•
Wear protective clothing such as hard hat, face
protection or safety goggles, safety gloves and if
necessary an apron.
•
The voltage on the rating plate must be identical
with the mains voltage.
•
Before each use, check the machine, connection
cable, plug, secure fit of the diamond core drill
bit and the fixing of the drill stand.
•
Always note follow the thread dimension of the
diamond core drill bit arbour. The thread of the
diamond core drill bits must fit on the thread of
the drive unit (G½" internal thread or 1¼" UNC
external thread) without any clearance. Do not
use reducers or adaptors for fitting the diamond
core drill bits.
•
Visually inspect the condition of the diamond
core drill bit.
NOTE
Damaged diamond core drill bits may not be used
and must be replaced immediately.
•
Only use the diamond core drill bits
recommended by OTTO BAIER GmbH for the
respective area of use.
NOTE
The diamond core drill bit can become irreparably
damaged by overheating or jamming in the drill
core hole (Page 43, "Handling diamond core
drill bits").
If harmful dust is produced during the work, a
suitable dust extractor must be connected to the
drive unit.
•
Connect a suitable dust extractor.
