Electronic Speed and Impact Control
(Fig. A, C)
The electronic speed and impact control
advantages:
- use of smaller accessories without risk of breakage;
- minimised break-out when chiselling or drilling in soft
or brittle materials;
optimal tool control for precise chiselling.

Torque Limiting Clutch

WARNING: The user must always maintain a firm grip on
the tool when in operation.
The torque limiting clutch reduces the maximum torque
reaction transmitted to the operator in case of jamming of
a drill bit. This feature also prevents the gearing and electric
motor from stalling.
Anti-Rotation System (Fig. C)
Ant-Rotation System offers increased user comfort and safety
through an on-board, anti-rotation technology capable
of detecting if the user loses control of the hammer. When a jam
is detected, the torque and speed are reduced instantly.
This feature prevents self rotation of the tool reducing
the occurrence of wrist injuries.
Service Indicator LEDs (Fig. A, C)
The yellow brushwear indicator LED
carbon brushes are nearly worn out to indicate that the tool
needs servicing within the next 8 hours of use.
The red service indicator LED
button 2 is used in any mode except the chipping mode.
On models fitted with Ultimate Torque Control, the red LED
indicator 16 lights up if the anti-rotational device is activated.
The red indicator starts to flash if there is a fault with the tool or
the brushes have completely worn out (refer to Brushes under
Maintenance).
Fully Vibration-Dampened Main Handle
(Fig. A)
The dampers in the main handle
transmitted to the user. This improves user comfort during
the operation.
ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
Fitting the Side Handle (Fig. B)
The side handle 3 clamps to the mounting area
case and may be rotated 360˚ to permit right- or left-hand use. The
side handle must be tightened sufficiently to resist the twisting
action of the tool if the accessory binds or stalls. Be sure to grip the
side handle at the far end to control the tool during a stall.
To loosen side handle, rotate counterclockwise.

1. Clean the bit shank.
2. Pull back the locking sleeve
3. Turn the bit slightly until the sleeve snaps into position.
4. 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.
5. To remove a bit pull back the tool holder locking sleeve/
collar 11 and pull the bit out of the tool holder

Setting the Electronic Speed and Impact
Control Dial (Fig. A, C)
Turn the dial 7 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.
