WARNING: Do not stare directly at the light beam. Never aim the beam at any person or
an object other than the work piece.
Do not deliberately aim the beam at personnel and ensure that it is not directed towards the
eye of a person for longer than 0.25s.
3.7.15 USING
(1) Drilling
Before use for drilling, the function mode selector should be set on drill position "
When drilling hard smooth surface, use a center punch to mark the desired hole location. This will prevent
the drill bit from slipping off center as the hole is started. Hold the tool firmly and place the tip of the drill or bit
into the work piece, applying only enough pressure to keep the bit cutting. Do not force or apply side
pressure to elongate a hole.
(2) Wood drilling
For maximum performance, use high speed steel bits for wood drilling. Turn the function mode selector on
the drill mode "
". Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
Increase the speed as the drill bit bites into the material. When drilling through holes, place a block of wood
behind the workpiece to prevent ragged or sintered edges on the back side of the hole.
(3) Metal drilling
For maximum performance, use high speed steel bits for metal or steel drilling. Turn the function mode
selector on the drill mode "
starting point. Maintain a speed and pressure which allows cutting without overheating the bit.
Applying too much pressure will:
-Overheat the drill
-Wear the bearings
-Bend or burn bits
-Produce off-center or irregular shaped holes
When drilling large holes in metal, it is recommended that you drill with a small bit at first, then finish with a
large bit. Also, lubricate the bit with oil to improve drilling action and increase bit life.
(4) Driving screw
-For maximum performance, use good quality bits for driving screws, turn the function mode selector on the
screwdriver mode position "21".
-Fix the torque setting low enough to allow a safety margin. Use a very low torque setting
when first driving small screws into soft materials. Then adjust the setting as the proper force required is
determined.
NOTE: The torque setting required depends on the item being driven. In the case of screws,
consider the size, length, and type of material.
(5) Hammer Setting
-For maximum performance, use a good quality masonry bit for hammer drill, turn the function mode selector
on the impact mode position "
". Begin drilling at a very low speed to prevent the bit from slipping off the
".
