accessories
(fig. C)
These models use SDS-max
®
drill bits and chisels
(refer to the inset in fig. C for a cross-section of an
SDS-max
®
bit shank).
• Unplug the tool.
• Insert the bit shank into the tool holder locking
sleeve (6) and turn the bit slightly until the sleeve
snaps in position.
• Pull on the bit to check if it is properly locked.
The hammering function requires the bit to be
able to move axially several centimetres when
locked in the tool holder.
• To remove a bit pull back the tool holder locking
sleeve (6) and pull the bit out of the tool holder.
Assembling and fitting the side handle
The side handle (8) can be mounted in front or in
rear position on either side of the Rotary Hammer to
suit both RH- and LH-users.
Always operate the Rotary Hammer with
the side handle properly assembled.
Mounting in front position (fig. D)
• Unscrew the side handle (8) and disassemble the
side handle clamp (20).
• Snap the steel ring (17) over the collar (7) behind
the tool holder (6). Squeeze both ends together,
mount the bush (18) and insert the pin (19).
• Place the side handle clamp (20) and screw on
the clamp wheel (9). Do not tighten.

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.
