unplug the tool.
DW541/DW545 - Setting the electronic speed
and impact control dial (fig. B)
• Turn the dial (2) to the desired level. The higher
the number, the greater the speed and impact
energy. With dial settings from "1" (low) to "7" (full
power) the tool is extremely versatile and
adaptable for many different applications. The
required setting is a matter of experience.
E.g. when using smaller diameter bits or when
drilling into ceramic or brittle materials, set the
dial to position "1" (low).
Selecting the operating mode (fig. B)
Your Rotary Hammer can be used in two operating
modes:
Hammer drilling:
simultaneous rotating and impacting - for
all concrete and masonry drilling
operations.
