SAFETY GUIDELINES
Work area safety
• Keeptheworkareacleanandwelllit.Cluttered or dark areas 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
• Theplugonthepowercord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.
• Avoidbodycontactwithearthedorgroundedsurfaces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.Water entering a power tool will increase
the risk of electric shock.
• Donotabusethecord.Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
• Whenoperatingapowertooloutdoors,useanextensioncordsuitableforoutdooruse.Use of
a cord suitable for outdoor use reduces the risk of electric shock.
• Ifoperatingapowertoolinadamplocationisunavoidable,useaground-faultcircuitinter-
rupter (GFCI) protected supply. Use of a CFCI reduces the risk of electric shock.

OPERATING INSTRUCTIONS
Fastening with screws (g 5)
g 5
The procedure shown will enable you to fasten materials together with your screwdriver without
stripping, splitting, or separating the material.
1. Clamp the pieces together and drill the first hole 2/3 the diameter of the screw. If the mate-
rial is soft, drill only 2/3 of the proper length. If it is hard, drill the entire length.
2. Unclamp the pieces and drill the second hole the same diameter as the screw shank in the
first or top piece of wood.
3. If a flat head screw is used, countersink the hole to make the screw flush with the surface.
Then, simply apply even pressure when driving the screw. The screw shank clearance hole
in the first piece allows the screw head to pull the pieces tightly together.
2. Drill the same
diameter as
screw shank.
1. Drill 2/3 diameter and 2/3 of
screw length for soft materials,
full length for hard materials.
Screw Apply a slight
even pressure
when driving
screws.
3. Countersink the same
diameter as screw.
