Soft Start Feature
D25941
The soft start feature allows the impact rate to build
up more slowly, thus preventing the chisel or point
from “bouncing” around on the masonry when
startingup.
Active Vibration Control
D25941
The active vibration control neutralises rebound
vibration from the hammer mechanism. Lowering
hand and arm vibration, it allows more comfortable
use for longer periods of time and extends the life of
theunit.

voltage only. Always check that the power supply
corresponds to the voltage on the ratingplate.
