ENGINE AR-PRIMARY 2197591 - Caterpillar

Use the host machine's boom to press the hammer firmly against the object. Do not pry the hammer with the boom. Correct force is applied when the host machine starts to feel light.
Start the hammer.
When the hammer tool penetrates the object, do not allow the hammer tool to move outward from the hammer. Keep boom down pressure on the hammer.
Do not operate the hammer while you move the hammer from one area to another area.

Do not operate the hammer in one spot for more than 15 seconds at a time. If the object does not break, stop the hammer and change the position of the hammer tool. If the hammer tool does not penetrate the object, stop the hammer and change the position of the hammer tool. When you operate the hammer too long in one location, stone dust is formed under the hammer tool. Stone dust will dampen the effect of impact on the object. Stone dust will also produce heat. Stone dust can cause the point of the tool to become deformed.Note: Listen to the hammer's sound while you are using the hammer. If the hammer's sound is thinner and the hammer's impact is less efficient, the hammer tool is misaligned with the object. Also, there is not enough down force on the hammer tool. Realign the hammer tool and press the hammer tool firmly against the object.

Do not strike and do not pry with the hammer tool at the same time. The hammer tool may snap off. The hammer tool may be bent by stones inside hard ground or frozen ground. Be careful and stop striking if you find sudden resistance under the tool.
