Hammering only:
for chiselling and demolition applications.
In this mode the tool can also be used as
a lever to free a jammed drill bit.
1. To select the operating mode, rotate the mode
selector switch (f) until it points to the symbol of
the required mode.
It may be neccessary to twist the tool holder (l)
slightly to allow the mode selector switch (f) to
pass the position.
2. Check that the mode selector switch (f) is
locked in place.
Indexing the Chisel Position
(fi g. 5)
The chisel can be indexed and locked into 24
different positions.
1. Rotate the mode selector switch (f) until it points
towards the position.
2. Rotate the chisel in the desired position.
3. Set the mode selector switch (f) to the
"hammering only" position.
4. Twist the chisel until it locks in position.
Setting the Electronic Speed and
Impact Control Dial (fi g. 1, 3)
Turn the dial (g) to the desired level. Turn the dial
upwards for higher speed and downwards for
lower speed. The required setting is a matter of
experience, e.g.
– when chiselling or drilling in soft, brittle materials
or when minimum break-out is required, set the
dial to a low setting;
– when breaking or drilling in harder materials, set
the dial to a high setting.

NOTICE: Always turn the tool off before
changing torque control settings or
damage to the tool may result.
Move the torque control lever (t) to setting 40 Nm or
80 Nm as needed for application.
• Clutch Setting 40 Nm (u) is designed for most
drilling applications and is designed to easily
clutch out when the drill bit encounters re-bar or
other foreign substances.
10
• Clutch Setting 80 Nm (v) is designed for higher
torque applications such as core-bits and deep
hole drilling and is designed to clutch out at a
higher torque threshold.
NOTE: If it is not possible to select position 80 Nm
run the unit under load and try again.
Each time the tool is plugged in, it will automatically
default to clutch setting 1 into clutch setting 40 Nm
(u), the most sensitive setting.
OPERATION
Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing set-
ups or when making repairs. Be sure
the trigger switch is in the OFF position.
An accidental start-up can cause injury.
WARNING: Tool bits may be hot and
gloves should be worn when changing
or removing them to avoid personal
injury.
WARNING:
• Be aware of the location of pipework
and wiring.
• Apply only a gentle pressure to the
tool (approximately 20 kg). Excessive
force does not speed up drilling but
decreases tool performance and may
shorten tool life.
• Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly assembled.
NOTE: Operating temperature is -7˚ to +40˚ C (19˚
to 104˚ F). Using the tool outside of this temperature
range will decrease the life of the tool.
Proper Hand Position (fi g. 6)
WARNING: To reduce the risk of
serious personal injury, ALWAYS use
proper hand position as shown.
WARNING: To reduce the risk of
serious personal injury, ALWAYS hold
securely in anticipation of a sudden
