ON/OFF sWITCH
Depress the On/Off switch to start and release it to stop your drill.
The on/off switch is fitted with a brake function which stops your
chuck immediately when you quickly release the switch.
It is also a variable speed switch that delivers higher speed and
torque with increased trigger pressure. Speed is controlled by the
amount of switch trigger depression.
Warning: do not operate for long periods at low speed
because excess heat will be produced internally.
sWITCH LOCK (see Fig. B)
The on/off switch trigger can be locked in OFF position. This helps to
reduce the possibility of accidental starting when not in use. To lock
the on/off switch, place the rotation control in the center position.
ReVeRsIBLe (see Fig. B)
For drilling and screw driving use forward rotation marked “ ” (lever
is moved to the left). Only use reverse rotation marked “ ” (lever is
moved to the right) to remove screws or release a jammed drill bit.
Warning: Never change the direction of rotation when the
chuck is rotating, wait until it has stopped!
CHUCK AdJUsTMeNT (see Fig. C)
To open the chuck jaws rotate the front section of the chuck. Insert
the drill bit between the chuck jaws and rotate the front section in
the opposite direction. Ensure the drill bit is in the center of the chuck
jaws. Finally, firmly rotate the front chuck section in the opposite
directions. Your drill bit is now clamped in the chuck.

sIGHT LIGHT
The sight light allows you to keep a clear view under less illuminated
circumstances. To turn on the light simply press the on/off switch.
When you release the on/off switch, the light will be off.
AUTOMATIC sPINdLe LOCK
The automatic spindle lock allows you to use it as a regular
screwdriver. You can give an extra twist to firmly tighten a screw,
loosen a very tight screw or continue working when the battery
energy has expired. For manual screwdriver purposes, the chuck is
automatically locked when the tool is off.
dRILLING (see Fig. d)
When drilling into a 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 bit at the point to be drilled. Depress the switch trigger to start
the tool. Move the drill bit into the workpiece, applying only enough
pressure to keep the bit cutting. Do not force or apply side pressure
to elongate a hole.
Tungsten carbide drill bits should always be used for
concrete and masonry. When drilling in metal, only use Hss
drill bits in good condition. When screw-driving, apply a small
quantity of liquid soap or similar to the screw threads to ease
insertion.
