ENGLISH
• 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.
Overload Clutch
In case of jamming of adrill bit, the drive to the drill spindle is
interrupted. Because of the resulting forces, always hold the
tool with both hands and take afirmstance. After the overload,
release and depress the trigger to re-engagedrive.
Mechanical Clutch
These tools are fitted with amechanical clutch. The indication
that the clutch has activated will be an audible ratcheting
together with increasedvibration.
Anti-Rotation System
In addition to the clutch, an anti-rotation system offers increased
user comfort 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 stopped
instantly. This feature prevents self rotation of the tool.
The anti-rotation system indicator
10
will illuminate to
indicatestatus.
Anti-Rotation and Service Indicator LED (Fig. A)
Your rotary hammer has two LEDs, indicating the Anti-rotation
(ADC) function and aservice indicator. Refer to the table for
more information on LEDfunctionality.

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. Be sure the
trigger switch is in the OFF position. An accidental start-up
can causeinjury.
Side Handle (Fig. A, B)

WARNING: To reduce the risk of personal injury, ALWAYS
operate the tool with the side handle properly installed.
Failure to do so may result in the side handle slipping
during tool operation and subsequent loss of control. Hold
tool with both hands to maximizecontrol.
The side handle
2
clamps to the front of the gear case and may
be rotated 360° to permit right- or left-hand use.
Mounting the Straight Side Handle (Fig. B)
1. Widen the ring opening of the side handle
2
by rotating it
anti-clockwise.
2. Slide the assembly onto the nose of the tool, through the
steel ring
14
and onto the collar
3
, past the chisel holder
andsleeve.
3. Rotate the side handle assembly to the desired position. For
hammerdrilling horizontally with aheavy drill bit, place the
side handle assembly at an angle of approximately 20° to
the tool for optimumcontrol.
4. Lock the side handle mounting assembly in place by
securely tightening the handle
2
rotating it clockwise so
that the assembly will notrotate.
Bit and Bit Holder

WARNING: Burn Hazard. ALWAYS wear gloves when
changing bits. Accessible metal parts on the tool and bits
may get extremely hot during operation. Small bits of
broken material may damage barehands.
The hammerdrill can be fitted with different bits depending on
the desired application. Use sharp drill bitsonly.
Inserting and Removing SDS MAX
Accessories (Fig. C)
This machine uses SDSMAX bits and chisels (refer to the inset in
FigureC for across-section of an SDSMAX bitshank).
1. Clean the bitshank.
2. Pull back the locking sleeve
7
and insert the bitshank.
3. Turn the bit slightly until the sleeve snaps intoposition.
