position that moulding onto the button of two speed selector.
The drill has a two-speed gear train designed for drilling at 1 (LOW) or 2 (HIGH) speed. A gear
selector is located on top of the drill to select either low or high speed. When you push the
button forward and select low speed range, the speed will decrease but will provide more
power and torque. When using drill in the high speed range. Speed will increase but will
provide less power and torque. Use low speed for high power and torque application and high
speed for fast drilling applications.
Important: NEVER adjust this two speed selector whilst the drill is running.
Always let it come to a complete stop first.

LED light (Fig 7)
The LED work-light can light prior to motor running if you press the switch lightly, which keep
the work area to be lighted for checking clearly at first, and it lights also during your operation.
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.
10 DRILLING
10.1
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.
10.2
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
shintered edges on the back side of the hole.
10.3
Metal drilling
For maximum performance, use high speed steel bits for metal or steel drilling. . Turn the
function mo
de selector on the drill mode “
”. Begin drilling at a very low speed to prevent the
bit from slipping off the 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
