without notice.

Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. They are
double-insulated in accordance with European Standard
and can, therefore, also be used from sockets without
earth wire.
Safety hints
For your own safety, please refer to the enclosed Safety
instructions.
SPECIFIC SAFETY RULES
GEB017-1
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict
adherence to screwdriver safety rules. If you use
this tool unsafely or incorrectly, you can suffer
serious personal injury.
1. Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
2. Always be sure you have a firm footing. Be sure
no one is below when using the tool in high loca-
tions.
3. Hold the tool firmly.
4. Keep hands away from rotating parts.
5. Do not touch the bit or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated
in this instruction manual may cause serious per-
sonal injury.
OPERATING INSTRUCTIONS
Removing or installing the bit (Fig. 1)
Important:
Always be sure that the tool is switched off and
unplugged before removing or installing the bit.
To remove the bit, first pull the stopper out of the locator.
Then grasp the bit with a pair of pliers and pull the bit out
of the magnetic bit holder. Sometimes, it helps to wiggle
the bit with the pliers as you pull. To install the bit, push
the bit firmly into the magnetic bit holder. Then install the
stopper by pushing it firmly into the locator.
Depth adjustment (Fig. 2, 3 & 4)
Push the locking sleeve in toward the motor and turn
slightly clockwise to lock it.
Turn the locator to adjust the depth. Initially, adjust the
locator so that the tip of the locator is flush with the base
of the screw head. One full turn of the locator equals 1.5
mm change in depth. After adjusting the locator, unlock
the locking sleeve. Turn the locking sleeve slightly so that
the protrusions on the locking sleeve engage in the
notches in the locator. Drive a trial screw into your mate-
rial or a piece of duplicate material. If the depth is not
suitable for the screw, continue adjusting until the proper
depth setting is obtained.
NOTE:
Before starting your job, always test-drive a sample
screw into a piece of the installation workpiece so that
you are sure to have the right depth and desired adjust-
ment.
Switch action (Fig. 5)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
To start the tool, simply pull the trigger.tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop. For continuous operation, pull the trig-
ger and then push in the lock button. To stop the tool from
the locked position, pull the trigger fully, then release it. A
speed control screw is provided so that maximum tool
speed can be limited (variable). Turn the speed control
screw clockwise for higher speed, and counterclockwise
for lower speed.
NOTE:
Even with the switch on and motor running, the bit will not
rotate until you fit the point of the bit in the screw head
and apply forward pressure to engage the clutch.
