LED WORK AREA LIGHT
The machine is equipped with LED light (3) to illuminate
the work area and improve visibility when drilling in areas
with insufficient light. To turn the LED light on press the
trigger of switch (5). LED light will automatically turn off 5
seconds after releasing the trigger of switch (5).
Electronic control may turn off the excessively overload-
ed machine in order to protect it. This mode is signalled
by blinking LED work area light (3). The power tool can
be used for its intended purpose after switching it on
again.
REVERSING (FIG. 3)
The extreme position of lever (4) to the right (viewed from
the rear) is equivalent to anti-clockwise rotation, the ex-
treme position to the left - to clockwise rotation. When
the ON/OFF switch (5) is depressed lever (4) can not be
actuated.
WARNING: Reversing can be performed
only when the spindle is not rotating!
Drilling and tightening screws are performed with lever
in extreme position to the left. Removal of screws is per-
formed with lever in extreme position to the right.
SWITCHING ON - SWITCHING OFF
Switching on: press ON/OFF switch (5).
Switching off: release ON/OFF switch (5).
The power tool is equipped with a brake. The spindle
stops rotating immediately after releasing the switch le-
ver.
MAX. TIGHTENING TORQUE PRE-SELECTION
Speed and tightening torque are directly correlated. The
lower the speed, the lower is the tightening torque.
The tightening torque can be adjusted in two ways:
- By pre-selecting the speed and max. tightening torque;
- By smooth adjusting the speed / tightening torque.

Battery capacity: 60 - 100%
Battery capacity: 30 - 60%
Battery capacity: < 30%
Battery capacity: < 20%. The battery
must be recharged.
Problems with battery. The display is
activated upon pressing the trigger of
the switch. It may show one of the fol-
lowing battery states:
▪ Low battery ► Battery has to be
recharged;
▪ Temperature protection has been
actuated ► Battery must be cooled
down prior to resuming operation;
▪ Damaged or unrecognized battery
► Battery has to be replaced
Pre-selecting the speed and max. tightening torque can
be accomplished by pressing button (7). Upon pressing
button (7) once, indicator (6) shows the selected setting.
Repeatedly pressing the button (7) will change the three
settings for maximum torque and this will be indicated by
one, two or three LEDs on indicator (6). One LED corre-
sponds to the lowest speed / torque, and three LEDs - to
the highest speed / torque.
The selected range is being saved even if the machine
has been switched off or the battery has been removed.
SMOOTH ELECTRONIC SPEED / TORQUE
CONTROL
Light pressure on ON/OFF trigger switch (5) results in
low rotation speed, further pressing the switch results in
smooth increase of the rpm to maximum upon reaching
the extreme position.
INSERTING AND REMOVING BITS
WARNING: Remove the battery or set the
forward/reverse switch (4) in central (neutral) position.
GUR 18Li HD (Fig. 4):
Inserting the bit:
1. Pull the locking sleeve (1) forward.
2. Insert the bit into the hexagonal socket of the tool
holder (2)
3. Release the locking sleeve. It will return in its initial
position and secure the bit.
WARNING: If the locking sleeve does not re-
turn to its original position, then the bit has not been
installed properly. Move the bit slightly back and forth
until the locking sleeve returns back in initial position.
When inserting the bit into the hex connector, make sure
it is inserted and locked in position before using the tool.
A bit not inserted and locked in position could exit the
connector during initial rotation and would be dangerous.
Removing the bit:
Pull the locking sleeve forward and keep it in this position
to remove the bit
GUR 18SLi HD:
Inserting the bit: Align the square opening of the socket
bit to the tool holder (2) and press it firmly.
Removing the bit: Pull the socket out to remove it.
OPERATING THE TOOL
Impact operation starts automatically when the load ex-
ceeds certain level. Pushing the trigger switch at no load
will result only in change of speed.
The fastening torque depends on the duration of impact
operation. Generally, maximum torque is achieved after
5 seconds of impact operation. Further operation will
result only in slight torque increase. Prolonged impact
operation may cause motor damage or burning.
The torque depends on the length, grade and diameter
