9. Note: Listen to the hammer's sound when you are using it. If the sound becomes
weaker and the impact less efficient, the tool is misaligned with the material
and/or there is not enough down force on the tool. Realign the tool and press the
tool firmly against the material.
10. Do not strike in one spot for more than 15 seconds at a time. If the object does
not break, or if the tool does not penetrate, stop the hammer and change the
position of the tool. Working too long in one spot will create stone dust under
the tool. Dust dampens the impact effect and produces heat.
11. Do not let the tool move outwards from the hammer when it penetrates. Keep
the down-pressure on the hammer while breaking.
12. To use the hammer most efficiently when breaking, concentrate on small steps
from the outer edge towards the middle.
13. When breaking hard or frozen ground, use the benching method. Start with
clearing a small area from the edge. Then continue by breaking material
towards the open area.
