Setting drilling depth
To drill several holes to the same depth, use
the depth stop (10). Insert a drill bit in the
rotary hammer as described.
Loosen the support handle (9) and insert the
straight end of the depth stop into the hole
on the support handle.
Get the tip of the depth stop � ush with
the tip of the drill bit. Push the depth stop
back as far as the required hole depth, then
secure it in place by retightening the support
handle.
Fitting drill bits/chisels
The rotary hammer is equipped with an SDS
drill chuck for � tting SDS accessories, such as
chisels, bits, or the accompanying drill chuck
with toothed rim.
Clean the accessory and apply a little engine
grease to the shaft before � tting it.
Insert the accessory's shaft into the SDS
drill chuck and turn it half a revolution
anticlockwise so that the accessory locks in
place.
Check that the tool is in the centre of the SDS
chuck and is secure.
If you intend to drill or chisel into a ceiling
or above shoulder height, put the dust cap
(16) over the accessory's shaft so that no dust
gets into the SDS drill chuck.
Removing tools
Pull back the collar on the SDS chuck, hold it
open and remove the tool.
