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.
  •  Always hold the tool firmly with both 
hands and ensure a secure stance 
(fig. 9). Always operate the tool with 
the side handle properly mounted.
Proper Hand Position (fi g. 9) 
   WARNING: To reduce the risk of 
serious personal injury, ALWAYS use 
proper hand position as shown. 
 
 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 
side handle (h), with the other hand on the main 
handle(b). 
  2. Replace the battery with the positive face 
pointing outwards.
  3. Close the battery compartment and secure the 
screw.

  1. Insert the required drill bit as described above.
  2. Press the depth rod button (i) and keep it 
depressed.
  3. Fit the depth adjustment rod (g) through the 
hole in the depth stop clamp.
  4. Adjust the drilling depth as shown.
  5. Release the depth stop clamp.
Reversing Lever (fi g. 7)
The forward/reverse lever(c) is used to reverse the 
rotation of the hammer for backing out fasteners or 
jammed bits in the drill-only function.
   CAUTION: When reversing to clear 
jammed bits, be ready for strong 
reactive torque.
To reverse the hammer, turn it off and align the 
forward/reverse lever(c) with the yellow arrow 
pointing backward.
To position the lever for forward operation, turn the 
hammer off and align the forward/reverse lever(c) 
with the yellow arrow pointing forward.
