WARNING: Always check the direction of rotation before operating the tool.
The tool must be set for forward or clockwise rotation only. Failure to obey this caution
may cause property damage.
WARNING:Always wear safety goggles or safety glasses with side shields and
unplug the tool before changing accessories or making adjustments. Failure to obey this
warning may cause serious personal injury.
WARNING:Be prepared for a sudden and tremendous twisting force or kick
back exerted by the tool. The tendency for the drill to grab or kick back in the opposite
direction is caused by hole breakthrough, the hole becoming clogged with chips or
concrete/masonry dust, or by striking hidden reinforcing bar embedded in the concrete.
WARNING: Always maintain a firm grip on both the auxiliary handle and switch
handle during drilling and hammer drilling operations. Failure to be prepared may result
in loss of tool control and possible serious injury.
