5. Always blow out the air line before using to clear the line
of dirt.
Do not operate the tool unless the chisel is against
the work since this will cause premature wear of
parts and reduce the vibration isolation properties
of the tool.
6. Always break material to the point of "give." Cracking
does not result in a complete break. Clear away rubble
as it is broken since uncleared rubble blocks the point
of "give."
7. Always take the right size "bite" with the tool. When
working new material, experiment to find the right size
"bite" required for breaking that material efficiently.

If "bites" are too big, the operator will try to pry
with the tool. This could break the chisel. The tool
is designed for demolition, not prying. Always use a
pick for prying.
If "bites" are to small, the operator will be working
too slowly.
8. If the chisel or accessory should become stuck, do not
use excessive force or mechanical means on the tool to
pull out the chisel. Break out the stuck chisel with a
spare chisel or tool.
