ASSEMBLY

FEATURES (FIG. 1)
The D25980 Pavement Breaker has been designed for professional heavy-duty demolition,
applications in concrete, brick, stone and other masonry materials.
ON/OFF Switch
The weight of the hand will active/deactivate the ON/OFF switch. Firmly grasp pavement breaker
while applying pressure with the right hand to turn the pavement breaker on. To turn the tool off,
remove the right hand to relieve pressure from the switch.
Soft Start
Holding tool by both handles depress the ON/OFF switch (A). The Soft Start feature allows the
impact rate to build up more slowly preventing the bit or point from bouncing around on the sur-
face. To stop the pavement breaker pull up on hand to relieve pressure from the switch to turn
the tool OFF.
SHOCKS™ – Active Vibration Control
The active vibration control (F) helps absorb the vibration transmitted to the user. This improves
user comfort and safety during operation.
Hold the tool firmly with one hand on the left side handle (C) and the other hand on the right
side handle (B). Using the right hand apply weight to the ON/OFF switch (A) to turn on. Apply
only enough pressure to the work area to engage the active vibration control. Applying too much
pressure will not make the pavement breaker chisel faster and the active vibration control will
not engage.
OPERATION
CAUTION: Always hold tool with both hands to maximize control. Allow the hammer to do the
work. Excessive added force shortens the life of the hammer and the accessory.
