Intended Use
Your breaker has been designed for professional heavy duty
demolition, chipping and chasing applications in concrete, brick,
stone and other masonry materials.
DO NOT use under wet conditions or in the presence of
flammable liquids orgases.
These breakers are professional power tools.
DO NOT let children come into contact with the tool.
Supervision is required when inexperienced operators use
thistool.
• Young children and the infirm. This appliance is not
intended for use by young children or infirm persons
without supervision.
• This product is not intended for use by persons (including
children) suffering from diminished physical, sensory or
mental abilities; lack of experience, knowledge or skills
unless they are supervised by aperson responsible for their
safety. Children should never be left alone with thisproduct.
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.
Fully Vibration-dampened Handles (Fig.A)
The dampers in the handles
2
absorb the vibrations transmitted
to the user. This improves user comfort during the operation.
Active Vibration Control
The active vibration control neutralises rebound vibration from
the breaker mechanism. Lowering hand and arm vibration, it
allows more comfortable use for longer periods of time and
extends the life of the unit.
