Your new WORX Rotary
Hammer Drill generates powerful forces
to get your job done quickly and effectively.
These forces may cause inferior quality
SDS bits to break and jam in the chuck, We
therefore recommend that only high quality
SDS bits be used with this tool.

wARNING: Do not use tools without
SDS-plus for hammer drilling or
chiseling!
Before mounting the drill bit, attaching the 13
mm keyed chuck, insert bit between the chuck
jaws as far as it will go. Ensure drill bit is in
the center of the chuck jaws. Using the chuck
key provided, there are three holes in which
the chuck key should be inserted. Tighten them
equally in turn at each of the three holes, not
just at one hole. Your drill bit is now locked
in the chuck. The bit can be removed by
reversing the above procedure (See Fig. B).
