a. Wear hearing protection when hammer drilling. The effect of noise can cause
hearing loss.
b. Use the additional handle(s). Loss of control can lead to injuries.
c. Support the power tool properly before using it. This power tool has a high torque.
Insufficient support of the power tool can lead to a loss of control and injuries.
d. Hold the electric tool exclusively on the insulated grip surfaces when performing
work in which the insertion tool may strike concealed power supply lines or its
own connecting lead. Contact with live lines can also charge metallic tool parts and
lead to an electric shock.
6.2 Safety directions for using long drill bits
a. Never work with a higher rotation speed than the maximum permissible
rotation speed for this drill bit. In case of higher rotation speeds, the drill bit might
warp slightly if it can rotate freely without touching the workpiece, and cause injuries.
b. Always start drilling at a low rotation speed and with the drill bit positioned on
the workpiece. In case of higher rotation speeds, the drill bit might warp slightly if it
can rotate freely without touching the workpiece, and cause injuries.
Do not exert excess pressure and only press in the longitudinal direction of the
drill bit. The drill bit can warp and break or lead to a loss of control and injuries.
