Assembly and adjustment
Prior to assembly and adjustment always
unplug the tool.
Inserting and removing SDS-max® accessories
(fig. C1 & C2)
This machine uses SDS-max® chisels (refer to the inset
in fig. C2 for a cross-section of an SDS-max® bit
shank).
• Clean and grease the bit shank.
Only apply a slight amount of lubricant to the
bit shank. Do not apply lubricant to the
machine.
• Insert the bit shank into the tool holder (6), and press
and turn the bit slightly until the sleeve snaps into
position.
• Pull on the bit to check if it is properly locked. The
hammering function requires the bit to be able to
move axially several centimetres when locked in the
tool holder.
• To remove a bit pull back the tool holder locking
sleeve (6) and pull the bit out of the tool holder.
Indexing the chisel position (fig. D1 & D2)
The chisel can be indexed and locked into 8 different
positions.
• Press the safety lock (5) and rotate the mode
selector (4) until it points rearward. Release the
safety lock.
• Rotate the chisel in the desired position.
• Press the safety lock (5) and rotate the mode
selector (4) back to the forward position indicated by
the hammering symbol.
• Release the safety lock and check that the mode
selector switch is locked in place.
• Twist the chisel until it locks in position.

Setting the electronic speed and impact control
dial (fig. B)
• Turn the dial (3) to the desired level. The higher the
number, the greater the speed and impact energy.
With dial settings from "1" (low) to "7" (full power) the
- tool is extremely versatile and adaptable for many dif
ferent applications. The required setting is a matter of
experience. E.g.:
- when chiselling soft, brittle materials or when
minimum break-out is required, set the dial to "1" or
"2" (low);
- when breaking harder materials, set the dial to "7"
(full power).
Assembling and fitting the side handle (fig. E)
The side handle (8) can be mounted on either side of
the machine to suit both RH- and LH-users.
Always operate the tool with the side handle
properly assembled.
• Snap the steel ring (13) over the collar (7) behind the
tool holder (6). Squeeze both ends together, mount
the bush (11) and insert the pin (12).
• Place the side handle (8) and screw on the clamp
knob (9). Do not tighten.
• Rotate the side handle mounting assembly to the
desired position.
• Lock the side handle mounting assembly in place by
tightening the clamp knob (9).
Instructions for use
• Always observe the safety instructions and applicable
regulations.
• For your own safety, always use the tool with both hands.
• Be aware of the location of pipework and wiring.
• Apply a pressure of approx. 20 kg to the tool.
Excessive force does not speed up chiselling but
decreases tool performance and may shorten tool life.
Switching on and off (fig. F)
• To switch on the tool, press the on/off switch (1).
• For continuous operation, depress the lock-on
button (14) on the on/off switch.
• To stop the tool, press the on/off swith again.
