1. Hammer drilling

 WARNING:

 Do not use tools without SDS-

 WARNING:

To work with tools without 

SDS-plus (e.g., drill with cylindrical shafts), 

a suitable drill chuck must be used.

Screw the SDS-plus adapter shaft (accessory) 

into a ring-gear or quick clamping drill chuck. 

Clean the adapter shaft and lightly grease the 

insertion end before inserting.
Insert the shaft of the assembled drill chuck 

with a twisting motion into the tool holder until it 

can be heard to lock.
The adapter shaft locks itself. Check the 

locking by pulling on drill chuck.
To remove the drill chuck, pull the plastic 

sleever to the rear, hold in this position and 

remove the drill chuck from the tool holder.

mode selector knob to the “hammering only” 

 position.

Insert the appropriate chisel. To adjust the 

head of the chisel to the desired angle, set 

the operating mode selector knob to the “bit 
rotation”   position and rotate the chisel 

by hand. Return the mode selector to the

Hold the tool firmly with both hands, Turn 

the tool on and apply slight pressure on the 

tool so that the tool will not bounce around, 

uncontrolled. Pressing very hard on the tool will 

not increase the efficiency.
