Figure 12. Floor Drilling Application
WARNING
This core drill can whip violently if it comes in contact
with rebar or coarse material which would cause the
shaft to bind. Be extremely careful at all times when
drilling. The possibility exists of the core drill severely
twisting the wrist or striking the body with excessive
force.
CAUTION
ALWAYS be on the lookout for exposed wiring or buried
electrical connections when drilling.
NOTICE
ALWAYS drill with uniform pressure and keep the bit
straight. When drilling through steel rebar, reduce the
pressure to avoid overloading the motor.
NOTICE
NEVER use the adjustable shoulder stock to pull the
bit out of the ground if the bit gets stuck in the hole.
