Unpacking 

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).

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.

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).

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.
