Operation S 83 STD
14. Stop the hammer quickly. Do not allow the hammer to fall down and make idle
strokes when an object breaks. Frequent idle strokes have a deteriorating effect
on the hammer. If the hammer falls through, the housing wears out more quick-
ly.
15. When breaking concrete, hard or frozen ground, never strike and pry with the
tool at the same time. The tool may break. Bending may be caused by stones
inside hard or frozen ground. Be careful and stop striking if you find sudden re-
sistance under the tool.
16. Keep the tool at a 90 degree angle at all times. If the object moves or its surface
breaks, correct the angle immediately. Keep the feed force and tool aligned.
