nism by turning the handle in a counterclock-
wise direction. Pivot the auxiliary handle into
the desired position.
Adjust the guide ruler to the desired drill-
ing depth” X “. Tighten the auxiliary handle

direction.
8. SET THE OPERATING MODE
With the operating mode selector knob, select
the operating mode of the machine. To change
the operating mode turning the operating
mode selector knob to the desired position un-
til you hear “click” to latch.
WARNING: Change the operating mode
only when the machine is switched off. Other-
wise, the machine can be damaged.
For drilling in steel or
wood, for tighten the
screws.
For hammer drilling in
concrete or stone.
Non-working position
used only to rotate a
flat chisel into the de-
sired position.
For light chipping and
chiseling applications.
In this mode the tool
can also be used as a
lever to free a jammed
drill bit.
9. TRIGGER CONTROLS
WARNING: To make sure you can control
the switch freely and keep it off before plug-
ging drill.
1) Intermittence work;
Start: Press the trigger.
Stop: Release the trigger.
2) To vary the drilling speed;
Simply increase or decrease pressure on the
trigger. The further the trigger is pressed, the
greater the drilling speed.
Reduced speed of the machine facilitates the
starting of holes (e.g., on smooth surfaces such
as tiles), prevents the slipping of drill and the
splintering of the drilled hole.
Recommended Speed Ranges:
• High speed for hammer drilling and chiseling
in concrete or stone.
• Medium speed for drilling in metal.
• Low speed for tighten the screws.
APPLICATION
WARNING: To reduce the risk of explosion,
before any work check the utility lines electric-
ity, gas or water supply line are hidden in the
work area.
WARNING: When working at low tempera-
tures:
The hammering mechanism begins to operate
only when the tool has reached a minimum op-
erating temperature.
Press the tip of the hammer bit briefly against
the work surface while the tool is running.
Repeat this procedure if necessary until the
hammering reaches the minimum operating
temperature.
1. HAMMER DRILLING
WARNING: Do not use tools without SDS
plus for hammer drilling!
Tools without SDS-plus and their holder and
drill chuck would be damaged by hammer drill-
ing. When working with tool without SDS-plus,
set the operating mode selector knob to posi-
tion “
”.
2. CHIPPING AND CHISELING
Before inserting the chisel, set the operating
mode selector knob to the “hammering only”
position.
Insert the appropriate chisel. To adjust the
head of the chisel to the desired angle, set the
operating mode selector knob to the “bit ro-
tation”
position and rotate the chisel by
hand. Return the mode selector to the “ham-
mering only”
