When operating a power tool outdoors, use an  
outdoor extension cord suitable for outdoor use.  
Use of a cord suitable for outdoor use reduces the  
risk of electric shock.  
Safety instructions  
WARNING. Read and understand all instructions. Failure to  
follow all instructions listed below may result in electric  
shock, fire and/or serious injury. The term “power tool” in  
all of the warnings below refers to your mains-operated  
(corded) power tool or battery-operated (cordless) power tool.  
Personal safety  
Stay alert, watch what you are doing and use  
common sense when operating a power tool. Do  
not use a power tool while you are tired or under the  
influence of drugs, alcohol, or medication. A moment  
of inattention while operating power tools may result in  
serious personal injury.  
Use safety equipment. Always wear eye protection.  
Safety equipment such as a dust mask, non-skid  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
Save these instructions  
Work area  
Keep work area clean and well lit. Cluttered and dark  
areas invite accidents.  
Do not operate power tools in explosive  
atmospheres, such as in the presence of flammable  
liquids, gases, or dust. Power tools create sparks which  
may ignite the dust or fumes.  
Keep children and bystanders away while  
operating a power tool. Distractions can cause you  
to lose control.  
Avoid accidental starting. Ensure the switch is in the  
off-position before plugging in. Carrying power tools  
with your finger on the switch or plugging in power  
tools that have the switch on invites accidents.  
Electrical safety  
Power tool plugs must match the outlet. Never  
modify the plug in any way. Do not use any adapter  
plugs with earthed (grounded) power tools.  
Unmodified plugs and matching outlets will reduce  
risk of electric shock.  
Avoid body contact with earthed or grounded  
surfaces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of electric shock  
if your body is earthed or grounded.  
Do not expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of  
electric shock.  
Do not abuse the cord. Never use the cord for carrying,  
pulling or unplugging the power tool. Keep cord away  
from heat, oil, sharp edges or moving parts. Damaged  
or entangled cords increase the risk of electric shock.  
Remove any adjusting key or wrench before turning  
the tool on. A wrench or a key that is left attached to  
a rotating part of the power tool may result in  
personal injury.  
Do not overreach. Keep proper footing and balance at  
all times. This enables better control of the power tool  
in unexpected situations.  
Dress properly. Do not wear loose clothing or jewellery.  
Keep your hair, clothing and gloves away from moving  
parts. Loose clothes, jewellery or long hair can be  
caught in moving parts.  
If devices are provided for the connection of dust  
extraction and collection facilities ensure that these  
are connected and properly used. Use of these devices  
can reduce dust-related hazards.

Power tool use and care  
Service  
Do not force the power tool. Use the correct power  
tool for your application. The correct power tool will  
do the job better and safer at the rate for which it  
was designed.  
Have your power tool serviced by a qualified repair  
personnel using only identical replacement parts.  
This will ensure that the safety of the power tool  
is maintained.  
Do not use the power tool if the switch does not  
turn it on and off. Any power tool that cannot be  
controlled with the switch is dangerous and must be  
repaired.  
Disconnect the plug from the power source before  
making any adjustments, changing accessories, or  
storing power tools. Such preventive safety measures  
reduce the risk of starting the power tool accidentally.  
Store idle power tools out of the reach of children  
and do not allow persons unfamiliar with the power  
tool or these instructions to operate the power tool.  
Power tools are dangerous in the hands of  
untrained users.  
Maintain power tools. Check for misalignment or  
binding of moving parts, breakage of parts and any  
other condition that may affect the power tool’s  
operation. If damaged, have the power tool repaired  
before use. Many accidents are caused by poorly  
maintained power tools.  
Additional safety rules for screwguns  
Remove the plug from the socket before carrying out  
any adjustment, servicing or maintenance.  
Fully unwind cable drum extensions to avoid potential  
overheating.  
When an extension cable is required, you must ensure  
it has the right ampere rating for your power tool and  
is in a safe electrical condition.  
Ensure your mains supply voltage is the same as your  
tool rating plate voltage.  
Your tool is double insulated for additional protection  
against a possible electrical insulation failure within  
the tool.  
Always check walls, floors and ceilings to avoid hidden  
power cables and pipes.  
After long working periods external metal parts and  
accessories could be hot.  
Do not put pressure on the screwgun, such that it slows  
the motor down. Allow the screwgun bit to cut without  
pressure. You will get better results and you will be  
taking better care of your tool.  
Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges are  
less likely to bind and are easier to control.  
Use the power tool, accessories and tool bits etc.,  
in accordance with these instructions and in the  
manner intended for the particular type of power  
tool, taking into account the working conditions  
and the work to be performed. Use of the power tool  
for operations different from intended could result in a  
hazardous situation.  
Always switch off before you put the screwgun down.  
Before operating, check that there is sufficient  
clearance for the screw under the workpiece.  
Only use accessory bits in good condition.  
Rags, cloths, cord, string and the like should never  
be left around the work area.  
If possible, always use clamps or a vice to hold  
your work.  
Ensure that the lighting is adequate.

Keep the area free of tripping hazards.  
Do not let anyone under 18 years operate this tool.  
Do not touch the bit after operation. It will be very hot.  
Keep your hands away from under the workpiece.

Unpacking  
Fitting a 1/4” shank bit  
1/4” Shank bits and bit holder  
extensions such as the one  
supplied as an accessory can  
be fitted into the magnetic hex  
shank bit holder (3) located  
inside the nose piece (1). The  
magnetic hex shank bit holder  
makes it easier and quicker to fit  
screw driving bits.  
When removing screws and other  
fasteners, make sure that the  
depth adjustment collar (2)  
is pulled all the way forwards  
towards the nose piece (1) and  
that forward/reverse switch (9) is  
positioned on the left-hand side  
of the tool (as viewed from the  
rear).  
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.  
Adjusting the driving depths  
The depth to which a screw is driven into the wall or other  
surface can be accurately set to suit the type of screw and  
the material being fastened.  
The driving depth is adjusted with  
the depth adjustment collar (2).  
1.Pull the depth adjustment  
collar forward towards the  
nose piece (1) as far as it  
will go.  
2.To increase the driving depth  
rotate the depth adjustment  
collar in a clockwise direction  
(viewed from the rear).  
3.To decrease the driving depth  
rotate the depth adjustment  
collar in an anti-clockwise  
direction (viewed from the  
rear).  
Switching on and off  
1.To switch the tool on, squeeze  
the variable speed trigger switch  
(7).  
2.The more pressure exerted on  
the switch the faster the motor  
will turn.  
3.Releasing the trigger switch  
stops the motor.  
CAUTION. Always maintain tight control of the tool when  
switching on and off and remember that the motor will  
continue to turn for a short while after switching off.  
4.When the driving depth has  
been correctly adjusted pull  
the depth adjustment collar backwards the rear of the  
tool until it touches the large hex nut (4) on the front  
of the tool housing.  
NOTE. It may be necessary to drive a number of screws  
into a test piece of material to establish the ideal driving  
depth adjustment.

Direction of rotation  
The direction of motor rotation  
is controlled by the forward/  
reverse switch (9).  
1.The bit rotates in a clockwise  
direction (viewed from the  
rear) when the forward/reverse  
switch is set to the right-hand  
side of the tool. This is the  
position required for driving  
screws and other fasteners.  
Speed selection  
The speed at which the motor turns when the trigger switch  
is fully depressed depends on the setting of the speed control  
(8).  
It is important to select the correct speed to suit the task. If  
necessary, trial the tool at different speeds to determine the  
optimum setting, start the trial at the slowest speed.  
1.Rotate the speed control in  
a clockwise direction (viewed  
from the rear) to increase the  
speed.  
2.The bit rotates in an anti-  
clockwise direction (viewed  
from the rear) when the  
forward/reverse switch is set to  
the left-hand side of the tool.  
This is the position required  
for removing screws and other  
fasteners.  
CAUTION. Never change the direction of motor rotation  
while the tool is switched on. Always switch off at the  
power point before operating the forward/reverse switch  
otherwise you could damage the motor.  
2.Rotate the speed control in an  
anti-clockwise direction (viewed  
from the rear) to decrease the  
speed.  
Operation  
When the tool is switched on and the motor is running,  
the magnetic hex shank bit holder (3) does not rotate.  
It is only when the bit or screw is pressed against the  
material being fastened that the screw bit turns.  
1.Fit the bit or bit holder extension into the magnetic hex  
shank bit holder (3) and ensure that the direction of  
rotation (forward or reverse) is correct.  
2.Switch on the tool. Ensure that the tool is held  
perpendicular to the head of the screw.  
3.Set the correct speed.  
4.Drive or unscrew the fastener by applying pressure  
to the screw head.  
Lock-on button  
The lock-on button (6) can be  
used to maintain the operation  
of the tool without having to  
constantly press the trigger switch  
(7).  
5.The magnetic hex shank bit holder will stop rotating  
when the pressure is released.  
1.Squeeze the trigger switch to  
set the desired speed of the  
motor.  
2.While holding the trigger switch depressed, push in the  
lock-on button (6). This holds the trigger switch in the  
on position without the need to constantly hold it.  
Belt clip  
The belt clip (4) permits the tool  
to be hung on a belt when not in  
use thus allowing the operator to  
use both hands for other tasks.  
When the tool is again required,  
it is conveniently available.  
3.To release the lock-on button, press and release the  
trigger switch.

Cleaning  
1. Keep your machine and its cord clean. The outside of  
the machine can be cleaned using a damp soft cloth  
with a mild detergent if required.  
2. Some maintenance products and solvents may damage  
the plastic parts; these include products containing  
benzene, trichloroethylene, chloride and ammonia.  
3. Excessive sparking generally indicates the presence  
of dirt in the motor or abnormal wear on the carbon  
brushes.  
4. Take special care to keep the ventilation inlets/outlets  
free from obstruction; cleaning with a soft brush  
followed by a compressed air jet will usually be  
sufficient to ensure acceptable internal cleanliness.  
5. Wear eye protection when carrying out cleaning.  
CAUTION. Do not use cleaning agents to clean the plastic  
parts of the drill.  
Power cord maintenance  
If the supply cord needs replacing, the task must be  
carried out by the manufacturer, the manufacturer’s  
agent, or an authorised service centre in order to avoid  
a safety hazard.
