3. When drilling into small work pieces secure the piece by clamping in a vise or otherwise securing it to the work surface so that the piece is not turned by the drill bit during drilling When driling into a structure that might contain electrical wiring be sure to know the location of the wiring and avoid driling into it The housing can carry electrical current from live electrical wires into which the drill is accidently drilled resulting in injury or death HAMMER DRILLING PERCUSSION Press the hammer drill bit against the work surface be fore squeezing the trigger Do not operate the drill before contacting the work surface When hammer driling do not exert heavy pressure on the tool Applying heavy pressure does not increase the drilling speed You need only press lightly When the drill is withdrawn from the work surface the percussion ac tion of the hammer drill stops CHISELLING Use the Bull point Chisel Bit for light duty chiselling work Press the hammer drill chisel bit against the work surface before squeezing the trigger As with hammer driling do not exert heavy pressure on the tool Press lightly The rotary motion of the hammer drill does not stop when chiselling The bull point chisel turns during chiselling When the chisel is withdrawn from the work surface the percussion action of the hammer dri stops Bull point chisels that become blunt can be sharpened grinding machine COL
