11. DRILLING
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 on/off switch 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.
If you want to activate the drill function (For
drilling metal wood or plastic), turn the torque
adjustment ring on the drill position.
If you want to activate the impact function(For
masonry or concrete), turn the torque adjustment
ring on the hammer position.
Tungsten carbide drill bits should always
be used for concrete and masonry.
When drilling in metal, only use HSS drill bits
in good condition. Always use a magnetic
bit holder (not included) when using short
screwdriver bits. When screw-driving, apply a
small quantity of liquid soap or similar to the
screw threads to ease insertion.
12. OVERLOAD PROTECTION
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately and
release the on/off switch. Then you can restart
the tool soon.
13. TEMPERATURE DEPENDENT OVERLOAD
PROTECTION
When using as intended for the power tool
cannot be subject to overload. When the load
is too high or the allowable battery temperature
is too hot, the electronic control switches off the
power tool until the temperature is in the optimum
temperature range again.

14. PROTECTION AGAINST DEEP
DISCHARGING
The Li-ion battery is protected against deep
discharging by the "Discharging Protection
System". When the battery is empty, the machine
is switched off by means of a protective circuit:
The inserted tool no longer rotates.

PROBLEM SOLUTION

1. WHY DOES THE DRILL NOT TURN ON
WHEN YOU PRESS THE SWITCH?
The forward/reverse rotation control, which is on
top of the on/off switch, is positioned in the lock
function. Unlock the forward/reverse rotation
control by putting it into the required rotation
position. Push the on/off switch and the drill will
start to rotate.
2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?
Verify the torque position of the torque adjusting
ring, you can find the torque-adjusting ring
between the chuck and the drill body. Position
1 is the lowest torque (screw driving force) and
position 22 is the highest torque (screw driving
force). Position
is for hammer drill operation. Regulate the
torque adjusting ring to a higher position to reach
the best result.
3. I CANNOT FIT THE BATTERY INTO THE
BATTERY CHARGER. WHY?
The battery can be inserted into the charger only
in one direction. Turn the battery around until it
can be inserted into the slot.
4. REASONS FOR DIFFERENT BATTERY
PACK WORKING TIMES
Charging time problems, as above, and having
not used a battery pack for a prolonged time will
reduce the battery pack working time. This can
be corrected after several charge and discharge
operations by charging & working with your drill.
Heavy working conditions such as large screws
into hard wood will use up the battery pack
energy faster than lighter working conditions. Do
not re-charge your battery pack below 0
above 45 C as this will affect performance.
