Active Vibration Control (Fig. 1)
D25223, D25323 AND D25324 ONL Y
The active vibration control r educes rebound vibration fr om the hammer mechanism. Reducing
hand and arm vibration allows for more comfortable use for longer periods of time and extends the
life ofthe unit.
For best vibration control, hold the tool with one hand on the main handle (B) and the other hand
on the side handle (I). Apply just enough pressur e so the hammer is approximately mid-str oke.
The hammer only needs enough pressur e to engage the active vibration control. Applying too much
pressur e will not make the tool drill or chip faster and active vibration control will not engage.
T orque Limiting Clutch
All rotary hammer drills ar e equipped with a torque limiting clutch that r educes the maximum
torque r eaction transmitted to the operator in case of jamming of a drill bit. This feature
also prevents the gearing and electric motor fr om stalling. The torque limiting clutch has been
factory-set and cannot be adjusted.
Side Handle (Fig. 2)
WARNING: T o reduce the risk of personal injur y , AL WA YS operate the tool with the side handle
properly installed and securely tightened. Failure to do so may result in the side handle slipping
during tool operation and subsequent loss of control. Hold tool with both hands to maximize control.
A side handle comes assembled with this rotary hammer . The side handle (I) can be fitted to suit
both right-hand and left-hand users.
TO ADJUST THE SIDE HANDLE
1. Loosen the side handle (I) by turning it counterclockwise.
2. Rotate the side handle to the desir ed position.
3. Tighten the side handle by turning it clockwise.
TO CHANGE SIDES
For right-hand users: slide the side handle clamp over the chuck, handle at the left.
For left-hand users: slide the side handle clamp over the chuck, handle at the right.

T o start the rotary hammer , depress the trigger switch (A). T o stop rotary hammer , release the
switch.
NOTE: Use lower speeds for starting holes without a centerpunch, drilling in metal, plastics or
ceramics, or driving screws. Higher speeds ar e better for drilling in masonry for maximum efficiency .
V ARIABLE SPEED
The variable speed trigger switch (A) permits speed control. The farther the trigger switch is
depressed, the higher the speed of the drill.
Lock-on Button (Fig. 1)
D25123, D25330
WARNING: Be sure to release the locking mechanism before disconnecting the plug from the
power supply . Failure to do so will cause the hammerdrill to start immediately the next time it is
plugged in. Damage or personal injury could result.

WARNING: T o reduce the risk of serious personal injur y , turn tool off and disconnect tool
from power source before making any adjustments or removing/installing attachments
or accessories.
WARNING: T o reduce the risk of personal injur y , AL WA YS ensure workpiece is anchored
or clamped firmly . If drilling thin material, use a wood “back-up” block to prevent damage to the
material.
Press mode selector button (E) and turn the mode selector (D) to the drill bit symbol for drilling, to the
hammer symbol for hammering or to the hammerdrill symbol for hammerdrilling.
DRILLING OPERA TION
1. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For MET AL, use high-
speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The
exceptions are cast ir on and brass which should be drilled dry . For MASONRY , use carbide-
tipped bits or masonry bits. A smooth, even flow of dust indicates the proper drilling rate.
2. Always apply pressur e in a straight line with the bit. Use enough pressur e to keep the drill bit
biting, but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to contr ol the twisting action of the drill.
WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip
the drill firmly with both hands to control the twisting action and avoid injury .
4. IF DRILL ST ALLS, it is usually because it is being overloaded. RELEASE TRIGGER
IMMEDIA TEL Y, remove drill bit fr om work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN A TTEMPT TO ST AR T A ST ALLED DRILL – THIS CAN
DAMAGE THE DRILL.
5. T o minimize stalling or breaking through the material, r educe pressur e on drill and ease the bit
through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to center punch the point to be drilled. Use a slow
speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
