children) suffering from diminished physical, sensory or
mental abilities; lack of experience, knowledge or skills

Soft Start Feature
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
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.
