Before starting to work:

1. Caution: When working with the tool, it must
be always held with both hands. Make sure that
you have a good foothold at all times. When drilling,
always use the side handle. Make sure the side
handle is correctly mounted and properly tight-
ened. Hold side handle at outermost end (fig. 6)
and stay alert. The drill bit can bind anytime.
2. Check that the electric supply is the same as
on the nameplate.
3. Don't press excessively on the tool. This
does not increase the hammering power. Simply
position and guide the tool.
Read the enclosed Safety Precautions.
Fig. 1: The connection end should be regularly
cleaned and lubricated sparingly with Hilti grease.
Shorten the start-up time in cold conditions by
jolting the drill bit, chisel etc. once briefly against
the work surface when switching on.

Electric tools must comply with the respective
safety regulations. Servicing, therefore, must only
be carried out by a skilled electrician or electrical
specialist. The use of original Hilti components
will provide an optimum of safety.
