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.

Set the maximum speed necessary by rotating
Original instructions
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. (Fig. 4)
REVERSING
The extreme position of lever 8 to the right
(Fig. 5a) is equivalent to clockwise rotation, the
extreme position to the left - to anti-clockwise
rotation (Fig. 5b). When ON/OFF switch 10 is
depressed lever 8 can not be actuated. Revers-
ing can be performed only when the spindle is
not rotating!
WARNING: Do not overload the
machine while operating it at left run. There
is a danger of tearing the securing screw and
unwinding the chuck.
OPERATION MODE SELECTION
▪ Drilling in metal, wood, etc. The switch 4 is in
its extreme right position the symbol "drill bit"
being exposed. (Fig. 6a)
▪ Drilling in concrete, stone, etc. The ON/OFF
switch 4 is in its extreme left position and the
symbol "hammer" is exposed. (Fig. 6b)
Switching the operation modes can be per-
formed while the machine is operated.
INSERTING AND fASTENING DRILL
BITS
Through turning the collar of the chuck 1 clock-
wise or counter-clockwise the jaws are posi-
tioned so the drill bit shank can be inserted in-
side the choke (Fig. 7a). By turning the collar of
chuck 1 counter-clockwise (looking towards the
chuck) the jaws tighten the drill bit shank. Fix
the drill bit finally in the chuck by means of the
chuck key, tightening equally in all three bores
(Fig. 7b).
PROTECTIVE CLUTCH
The machine is equipped with protective clutch.
An audible click is heard upon actuating the
clutch and the spindle halts or barely rotates.
