To use the HDC300 with larger
SDS-max combination rotary or
demolition only hammers, the
attachment comes with a total
of 3 hammer adaptors. Use the
appropriate size adaptor for the
appropriate size hammer (Fig.
4).
To change the hammer
adaptor, remove the adaptor
from the metal extension arm
by using a flat edge screwdriver
and wedging it between the
metal arm and the adaptor.
Insert the desired hammer
adaptor into the slot on the
metal arm (Fig. 5). Follow steps
to install on to the hammer.

Chiseling only: The HDC300 is designed to be
used for chiseling in masonry and concrete
materials with either SDS-max or Spline chisels.
The dust extraction attachment should be
positioned approximately 3" from the tip of the
bit for best dust extraction results (Fig. 6). You
can adjust the positioning of the attachment by
opening the clamping band lever and sliding the
attachment forwards or backwards on the
hammer tube. For extending the adjustment,
the extension arm can be moved forwards or
backwards within the clamping band
mechanism. When complete, close the
clamping band lever to re-secure the
attachment to the tool (Fig. 7).
