FEATURES (FIG. 1)
I
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 surface. 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.

before installing and removing accessories, before adjusting or when making repairs. An

work. Excessive added force shortens the life of the hammer and the accessory.
