The required setting depends on the bit size and hardness of
material being drilled.
•
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
9
will illuminate to indicate
status.
Anti-Rotation System and Service Indicator LED
(Fig. A)
Your rotary hammerdrill has two LEDs, indicating the Anti-
rotation system and a service indicator. Refer to the table for

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.
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
qs
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
qs
by rotating it
counterclockwise.
2. Slide the assembly onto the nose of the tool, through the
steel ring
qd
and onto the collar
2
, 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
qs
rotating it clockwise so
that the assembly will not rotate.
