torque adjustment ensures machine utilization
as a screwdriver.
PRIOR TO INITIAL OPERATION
▪ Make sure the power supply voltage corre-
sponds to the value indicated on the name
plate with technical data of the tool.
▪ Always check the position of ON/OFF switch.
The power tool must be connected to the
power supply socket only when this switch is
in OFF position. If the plug is connected to
a receptacle while the power switch is in the
ON position, the power tool will start operat-
ing immediately, which could cause a serious
accident.
▪ Make sure that the cord and the plug are in
order. If the replacement of the supply cord is
necessary, this has to be done by the manu-
facturer or his agent in order to avoid a safety
hazard.
WARNING: Always switch off and
unplug the power tool prior to any adjustment,
servicing or maintenance.
▪ In case the work area is remote from the pow-
er source, use as short as practicable exten-
sion cord with proper cross-section.
▪ Check that the auxiliary handle is properly
mounted and reliably tightened.
WARNING: Prior to operation always
check the direction of rotation. Shift the
reversing switch only when the spindle has
come to a complete stop. Reversing prior to
final spindle halt may damage the power tool.
SWITCHING ON - SWITCHING Off
Brief activation
▪ Switching on: press ON/OFF switch 10.
▪ Switching off: release ON/OFF switch 10.
Continuous operation
▪ Switching on: press ON/OFF switch 10 and in
pressed position lock it by button 11.
▪ Switching off: press ON/OFF switch 10 once
and release it immediately.
TWO-SPEED SELECTOR SWITCH
Rotate switch 12 to 180° clockwise or anti-clock-
wise, in order to select one or the other speed
range. The direction of rotation for switching is
shown on the switch.
Original instructions
TRIGGER SPEED CONTROL
BUR2 350E
Set the maximum speed necessary by rotating
thumbwheel 9 in position A - G. Position A cor-
responds to minimum rpm, position G - to maxi-
mum rpm.
Light pressure on ON/OFF switch 10 results
in low rotation speed, further pressing the trig-
ger results in smooth increase of the rpm to the
pre-selected maximum by thumbwheel 9 upon
reaching the extreme position.
BUR2 350CET
The necessary speed can be pre-selected by ro-
tating thumbwheel 14 in position À - G. Position
A corresponds to minimum rpm, position G - to
maximum rpm.
Light pressure on ON/OFF switch 10 results
in low rotation speed, further pressing the trig-
ger results in smooth increase of the rpm to the
pre-selected maximum by thumbwheel 14 upon
reaching the extreme position. Thus optimum
mode for drilling in different materials (metal,
wood, plastics, etc.) is achieved.
REVERSING (BUR2 350E,
BUR2 350CET)
The extreme position of lever 8 to the right is
equivalent to clockwise rotation, the extreme
position to the left - to anti-clockwise rotation.
When ON/OFF switch 10 is depressed lever
8 can not be actuated. Reversing can be per-
formed only when the spindle is not rotating!
only when the spindle is not rotating!
TORqUE CONTROL (BUR2 350CET)
Select the toque by regulator 13:
- Position I corresponds to minimum torque.
- Position III corresponds to maximum torque.
- Position IV (after pos. III) - regulator 13 is
switched off.
When the reversing lever 8 is in left position,
regulator 13 is switched off.
Use maximum torque for normal drilling. Do not
operate the machine continuosly at low speed
and high torque.
LED INDICATION
A. Green LED pos.15 - Indicates the spindle ro-
tation direction:
- Constant glow: the machine is supplied from
the mains, right rotation direction of the spindle;
- Blinking glow with frequence f=1Hz: the ma-
chine is supplied from the mains, left rotation
