additional safety instructions
for hammer drills
concealed items. drilling into con-
cealed items can cause personal injury
or property damage. always make sure
the area of drilling is free from items other
than masonry material, such as rebar,
wire mesh, water or gas pipes, electrical
conduit or wires, etc.
holding hammer drill. the ham-
mer drill produces significant torque dur-
ing operation. to maintain control of the
tool, always firmly hold the grip with one
hand and the auxiliary handle with the
other before starting the tool and during
operation.
drill bit. if the bit is not firmly locked
in the chuck, it could be thrown from the
tool and cause personal injury or property
damage. always make sure the bit is prop-
erly locked in the chuck and is against the
workpiece before starting the drill.
holding hammer drill. the ham-
mer drill produces significant torque dur-
ing operation. to prevent injuries from
loss of control, always firmly hold the grip
with one hand and the auxiliary handle
with the other before starting the tool and
during operation.
removing bit. drill bits can become
extremely hot during operation. always
use a rag or heavy work gloves to protect
your hands when removing hot drill bits.
disconnect tool. to avoid unexpect-
ed start-up, always disconnect the drill
from power before changing bits. never
leave the tool connected to power when
left unattended.
removing bit from hole. if the
drill stops rotating while it is in the hole,
it could become stuck and difficult to
remove. always remove the bit from the
hole while it is still rotating and turn the
tool
OFF just as the bit leaves the hole.
personal protective eQuipment
(ppe). dust and flying debris could cause
respiratory, eye, or skin injuries. the noise
caused by the hammer drill could cause
hearing loss over time. always wear an
approved respirator, safety glasses and
face shield, heavy work gloves and long
sleeves, and hearing protection when
using the hammer drill.
electrical cord. to avoid electrical
injuries or cord damage, always make
sure the electrical cord of the drill and
any extension cords are trailing behind
the tool clear of the drilling area, and kept
away from wet areas. immediately replace
cord if damaged.
rest periods. Long-term exposure to
vibration from operating the hammer drill
could cause hand and arm injuries. to
reduce this risk, take frequent breaks that
are at least as long as the period of opera-
tion. Comfortably move fingers and hands
around to increase circulation during the
rest periods.
sparKs. sparks produced during normal
operation could ignite flammable materi-
als or fumes. do not operate the hammer
drill near flammable material or fumes.
if there are excessive sparks, stop the
hammer drill immediately and resolve the
issue before continuing.
