For best vibration control, hold the tool with one
hand on the main handle (h) and the other hand on
the side handle (e). The hammer only needs enough
pressure to engage the internal active vibration
control. Applying too much pressure will not make
the tool drill faster and active vibration control will not
engage.

OPERATION
Instructions for Use
WARNING:
• Always observe the safety instructions
and applicable regulations.
•
Be aware of the location of pipework
and wiring.
•
Apply only a gentle pressure to
the tool (approx. 5 kg). Excessive
force does not speed up drilling but
decreases tool performance and may
shorten tool life.
•
Do not drill or drive too deep to
prevent damage to the dust cover (o).
•
Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly mounted.
WARNING: To reduce the risk of
serious personal injury, turn tool
off and disconnect battery pack
before making any adjustments or
removing/installing attachments or
accessories.
Proper Hand Position (fi g. 1, 6)
WARNING:
To reduce the risk of
serious personal injury,
ALWAYS
use proper hand position as shown
in figure 6.
WARNING:
To reduce the risk of
serious personal injury,
ALWAYS
hold
securely in anticipation of a sudden
reaction.
Proper hand position requires one hand on the
main handle (h), with the other hand on the side
handle (e).
Drill Operation (fi g. 1)
WARNING:
To reduce the risk of
serious personal injury, turn tool off and
disconnect tool from power source
before making any adjustments or

firmly. If drilling thin material, use a wood
“back-up” block to prevent damage to
the material.
