Due to modern mass production techniques, it is unlikely
that your GMC Power Tool is faulty or that a part is missing.
If you find anything wrong, do not operate the tool until the
parts have been replaced or the fault has been rectified.
Failure to do so could result in serious personal injury.
Another feature of the drill/battery pack is the low voltage
cut out feature. This feature operates when the voltage
drops below a pre set value. When this occurs the tool will
automatically stop operating. To correct the situation you
need to either insert another charged battery into the drill
or recharge the existing battery, and then proceed with the
drilling/driving application.
Important information – Product care
This drill driver uses Lithium Iron Battery Cells. Care
MUST be taken to ensure both the safety and life of the
pack is maintained. Ensure you have read all of the safety
notes in the previous pages before using the drill/driver.
Note: Attempting to restart the tool in this condition without
either recharging the battery or installing a battery with
charge will lead to drill restarting and then stopping again
after only a few seconds of operation.
Safety devices and circuitry for this tool are located in
the battery pack of this tool. The battery pack is a vital
component, not just for the power source, but also for
the full safety control for both the charging and also the
tool operation. Treat the battery pack with care and within
the guidelines of this manual. If the pack does become
immersed in water or any fluids, or is subject to a sever
drop etc, or it does not operate within the guidelines of

CAUTION. Do not continue to overload the drill and
constantly reset the overload. Doing this will cause the
battery cells to over heat.
Using the drill
Trigger switch
Use the forward/reverse switch (4) to select the direction
of rotation, then pull the trigger (3). This trigger switch is an
electronic variable speed control which enables the user to
vary the speed continuously. The speed varies according
to how far the trigger switch is depressed. The further it is
depressed the faster the chuck will rotate and the lighter it
is depressed, the slower it will rotate.
Temperature Cut Out
If the drill is constantly overloaded, or the drill is used
constantly at maximum rating in high ambient conditions,
the battery cells may over heat causing the battery pack
to shut down.
The yellow indicator on the battery pack will stay illuminated
in this condition. When this occurs you will need to
immediately stop drilling and allow the battery cells to
reduce the temperature.
To stop the drill, release the trigger switch.
To reduce the temperature of the cells remove the battery
pack from the drill and place the battery pack in a free air
environment, out of direct sunlight or any other heat source.
DO NOT force cool the pack in any way. Do not place in
refrigerators or freezers.
When the battery pack has cooled down it can again
be used to operate the drill, as long as the load or the
conditions causing the original excessive temperature
has been corrected.
Note. The variable Speed control fitted to this drill is NOT
intended to be used for long periods of time during the
operation of the task being performed. Use the variable
speed to start drilling and screwing tasks, and then fully
depress the trigger once the task has started.
Low voltage cut out
The battery pack used on this tool is fitted with a low
voltage cut out feature within the circuitry.
CAUTION. Extended use of the variable speed under
load will overload and then permanently damage the
speed control.
The low voltage cut out feature operates when the voltage
drops below a pre set value. This feature automatically
stops the drill from operating (similar to that of the over
load condition). When this condition occurs you will need
to either insert another battery into the drill or recharge the
existing battery.
Drill Overload
This drill is fitted with an overload protection. If the drill is
excessively forced, or the task being performed is too great
for the drill, the drill will automatically go into an overload
mode. When the drill goes into overload, the drill will
automatically and suddenly STOP. To reset the overload,
simply release the trigger. When the trigger is pressed
again, the drill will restart. Resume work after the overload
has been reset, but reduce the load by using a smaller drill
bit or re-sharpen the existing drill bit and reduce the amount
of force placed on the drill.
The low voltage cut out feature has been added to
maximise the tools life. When this occurs, recharge the
battery pack by following the battery charging section in
this manual.
Note: Attempting to restart the tool without either recharging
the battery or installing another battery (with charge) will
lead to drill restarting and then stopping again, after only a
few seconds of operation.

This switch (4) will allow you to
change the direction of the motor
while the trigger switch is not
depressed.
Inserting and removing bits
This drill has a keyless chuck,
which means that a chuck key
is not needed to secure a bit in
the drill.
Drilling uses the forward mode. The reverse mode is
intended for the removal of screws and assisting to remove
jammed drill bits.
1. Open the chuck by holding
the rear section of the chuck
firm and rotating the front
section in a anti-clockwise
direction, sufficiently enough
to allow the drill bit required
to fully enter the jaws of the chuck.
Adjustable torque
This drill is equipped with 21
torque settings plus one drill
setting which are controlled
by the torque collar (8). All of
the torque settings are clearly
identified on the torque collar.
To adjust the torque setting you
rotate the torque collar. Rotate
the torque collar clockwise to
increase the torque setting and
rotate it anti-clockwise to decrease the torque setting.
2. Ensure the drill bit is fully inserted, so that the chuck
jaws grip the straight section of the bit.
3. Holding the rear section of the chuck firmly, rotate the
front section of the chuck clock-wise until the jaws tighten
on the drill bit. The front section of the chuck needs to be
tightened firmly to ensure the drill bit is held securely.
Controlling the torque allows for better control when using
the drill on specific tasks and prevents over-fastening and
over-tightening.
4. To remove the drill bit, hold the rear section of the chuck
firmly and rotate sharply the front section of the chuck in
a anti-clockwise direction, sufficiently enough to allow the
drill bit to be removed.

Chuck replacement
Drilling metals
The chucks of reversible drills are always fixed by a screw
with a left-hand thread. The screw, which is located in the
centre of the chuck, must be removed before the chuck can
be removed. To remove the screw, turn it in a clockwise
direction. The chuck can now be removed by unscrewing it
anti-clockwise. If you have trouble removing the chuck take
the drill to your nearest authorised service centre for chuck
replacement.
