invite accidents.
 Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
 Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
 Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
 Avoidbodycontactwithearthedorgroundedsurfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
 Do not expose power tools to rain or wet conditions.
 Do not abuse the cord. Neveruse the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges and moving parts.Damaged
or entangled cords increase the risk of electric shock.
 When operating a power tool outdoors, use an exten-
sioncord suitablefor outdooruse. Use ofa cord suitable
for outdoor use reduces the risk of electric shock.
 If operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.

Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus tools are re-
quired that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drill bits with cylindrical shank). For thesetools, a
keyless chuck or a key type drill chuck are required.
Inserting/Removing the Key Type Drill Chuck
