Direct the hydraulic breaker in a position 90°
♦
towards the object.
♦ Start near the edge and work your way in towards
the middle. Never start in the middle of large
objects.

♦ Use the correct feed pressure. When the feed
pressure is correct the hydraulic breaker is working
at its best and the vibrations are at a minimum.
Also the wear on the bushing and tool is kept to
a minimum.
♦ Listen to the sound from the hydraulic breaker.
The sound changes if there is any bending
between the tool and bushing.
♦ Never run the breaker with the boom cylinders at
their end positions. It may cause damage to the
carrier.
Avoid idling strokes; it causes wear on both
♦
working tool and tool retainers.
