 Use
electrical drills appropriate for the core drill used.
Be sure to turn off the
main switch of the drill and disconnect the power supply plug from
the socket before attaching and detaching the core drills.
Do not touch the core drill,
the shavings, or the drilled hole because they may be hot.
Wear working clothes suitable
for the operation, including eye protection equipment to prevent shavings
from getting into your eyes.
Prepare the working environment
before starting jobs.
Read carefully the instruction
manual for the electrical drill used before use. |
