Adjustable torque settings
Your cordless drill features 19+1 torque settings for
driving different types of screws into different types of
materials. The output torque increases as the torque ring
(A) Fig.5 is rotated from 1 to 19. Correct torque settings
are as follows, setting 1-2 is ideal for driving small
screws, setting 3-4 is ideal for driving medium sized
screws into soft material, setting 5-6 is ideal for driving
screws into soft and medium density materials, setting 7
is ideal for driving screws into hardwood, setting 8 is ideal
for large screws. Using the highest setting (final torque
setting 20, indicated by a drill bit) allows you to perform
heavy duty drilling operations.
Speed selector
Before an operation, set the speed selector switch (B) Fig.5 to the desired speed. Slide the
speed selector towards the rear for high-RPM operation or towards the front for low-RPM
operation. It is recommended to use the low-RPM setting for drilling large holes or driving
screws, use the high-RPM setting for drilling small holes.
Warning! Do not attempt to change the speed setting during an operation, damage to the
gear may result.
Electric brake
This cordless drill is equipped with an electric brake. If
the tool consistantly fails to stop quickly after the trigger
is released, have the tool serviced.
LED light
Your cordless drill features a LED light system (A) Fig.6
which gets activated by pressing the trigger. This feature
is ideal when working in partially lit work environments.
Installing drill bit in keyless chuck
To open the keyless chuck jaws, turn the chuck sleeve
(A) Fig.7 counterclockwise. To close the chuck jaws, turn
the chuck sleeve clockwise.
For small drill bits, open chuck jaws enough and insert
the drill bit up to the flutes. For larger drill bits (B) Fig.7,
insert the bit as far as it will go. Centre the bit as you
close the jaws of the keyless chuck by hand. This
positions the drill bit properly, giving maximum contact
between the chuck jaws and the drill bit shank.
Pay Attention! Drill bit must be properly inserted in keyless chuck with all three jaws
holding the drill bit centred in the chuck. If not, this could cause the drill bit to be thrown
from the chuck resulting in possible serious injury.
Warning! Before removing drill bit after any operation, let the drill bit cool down before
attempting to remove it and touching it with your fingers, risk of burning!

OPERATION
Operational steps-drilling
When drilling metal, it is recommended to use a light oil on the drill bit to keep it from
overheating.
1) Make sure the drill bit is firmly locked in the keyless chuck and set the direction of
rotation using the forward/reverse switch.
2) Set the torque setting ring to the highest setting.
3) Secure workpiece in vise or other type of support. Hold the drill firmly with both hands,
place the point of the drill bit at the point to be drilled and depress trigger to start the
drilling operation. Always use the higher speed setting for drilling small holes, use the
lower speed setting for drilling larger holes.
4) Move the drill bit into the workpiece applying only enough pressure to keep the drill bit
cutting. Do not force the drill bit or apply sideways pressure.
Operational steps-driving screws
1) Make sure to use the correct screwdriver bit that correctly fits the screw being driven.
2) Fasten screwdriver bit into the chuck, making sure the flat of the bit are gripped by the
chuck jaws.
3) Set the torque setting ring to the appropriate setting as described in the adjustable
torque setting section.
Drilling wood or plastic
If backup material is not used, ease up on the pressure just before the bit breaks through
the wood to avoid splintering. Finish the hole from the opposite side after the point breaks
through. If it binds, reverse the drilling operation to help remove the bit from the work.
Drilling metal
Make a centre punch in the metal to be drilled for easier starting. Use just enough
pressure to keep the bit cutting. Do not apply great pressure on this tool when drilling
metals. When drilling large holes, it is faster and easier on your power pack to first make
a smaller hole and to then enlarge it to the size desired. Lubricate the tip of the bit
occasionally with light oil for easier metal drilling. If it binds, reverse the drilling operation
to help remove the bit from the work. It is not recommended to drill holes larger than 3/8"
diameter through soft steel thicker than 1/8". Drilling through metal rapidly drains energy
from your battery.
Fastening with screws
The illustration Fig.8 on the next page illustrates how to fasten materials together with your
cordless drill without stripping, splitting or separating the material being drilled.
1) Clamp the pieces together and drill a hole 2/3 the diameter of the screw to be used. If
the material is soft, drill up to 2/3 of the length of the screw to be used and for hard
material drill the entire length of the screw.
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, coutersink the hole to make the head of the screw flush with
the surface of the piece of wood. Then, apply even pressure when driving the screw.
The screw shank clearance hole in the first or top piece allows the screw head to pull
the two pieces together.
