Instruction & User Manual

Mode Selector

Drilling Mode 

Use the correct specification of drill bit for 
the material and power tool you are working 
with. Incorrect selection may cause damage 
to the tool, workpiece or bit.

WARNING!

Check that the drill bit is correctly inserted 
into the chuck before starting the power 
tool.

NOTE

m

If loose, clamp the work piece. The work 
piece should lie flat on a workbench, and/or 
be securely fixed.

m

Mark out the position of the hole by suitable 
means. 

m

Use a suitable drill bit for your material.

m

Ensure all drill bits are sharp.

m

When drilling in metal, make sure that the 
drill bit is always sufficiently cooled with a 
non-flammable liquid.

m

Start drilling at low speed.

m

If you are drilling large holes, pre drill with a 
small drill bit and then finish off with a large 
drill bit.

m

Do not force the power tool - do not press 
too hard on the drill bit.

The drill bit can jam in deep holes. Release 
the power switch immediately if the drill bit 
jams. Switch to anticlockwise rotation and 
run the drill bit loose at low speed.

NOTE

Hammer Drilling Mode 

m

Set the mode selector switch to this mode 
to enable the hammer function alongside 
drilling. The hammer drilling function allows 
more effective drilling into hard, brittle 
materials such as concrete, brick and stone.

Percussion Chiselling Mode 

m

Set the mode selector switch to this mode 
to enable the percussive hammer function 
without rotating the tool. The percussion 
chiselling function allows fast removal of 
hard, brittle materials such as concrete, brick 
and stone.

Chisel Adjustment Mode 

m

Chisel adjustment mode unlocks the chuck, 
allowing the user to rotate the attached tool 
to the required position.
