SELECTING A DRILLING MODESee Figure 14.To adjust for type of drilling, slide the mode selector onthe side of the motor housing to hammer mode, screwmode, or drilling mode.Select screw mode for driving screws. Screw modeoperates with user adjusted torque. (See AdjustableTorque Clutch.)Drill mode is for full torque operations only and bypassesthe clutch setting. Select drill mode when drilling withtwist drills, hole saws, etc., in soft materials, or when theapplication calls for full torque of the drill.Select hammer mode for masonry, brick, tile, andconcrete. For maximum performance, use carbide-tippedimpact masonry bits.To use the hammer mode:[] Rotate the mode selector to the hammer mode.[] Apply light pressure and medium speed for best resultsin brick.[] Apply additional pressure and high speed for hardmaterials such as concrete.[] When drilling holes in tile, practice on a scrap piece todetermine the best speed and pressure.NOTE: The hammer drill has not been designed forreverse hammering.TO DECREASETORQUETOINCREASETORQUETORQUEADJUSTINGRiNGMODESELECTORFig. 14DRILLINGSee Figures 15- 16.Levels are located on the top and end of the motorhousing to help keep the drill bit level during use.[][][][][]Fig. 15Check the direction of rotation selector for the correctsetting (forward or reverse).Secure the material to be drilled in a vise or withclamps to keep it from turning as the drill bit rotates.Hold the drill firmly and place the bit at the point to bedrilled.Depress the switch trigger to start the drill.Move the drill bit into the workpiece, applying onlyenough pressure to keep the bit cutting. Do not forcethe drill or apply side pressure to elongate a hole. Letthe tool do the work._IL WARNING: Be prepared for binding at bitbreakthrough. When these situations occur, drill hasa tendency to grab and kick opposite to the directionof rotation and could cause loss of control whenbreaking through material. If not prepared, this lossof control can result in possible serious injury.[] When drilling hard, smooth surfaces, use a centerpunch to mark the desired hole location. This willprevent the drill bit from slipping off-center as the holeis started.[] When drilling metals, use a light oil on the drill bit tokeep it from overheating. The oil will prolong the life ofthe bit and increase the drilling action.16
