Using inserted tools that do not fulfil the criterias
mentioned below, will result in a longer time to
complete a task, and may result in higher levels of
vibration exposure. A worn tool will also cause
increased working time.

►
not worn out and of the proper size.
► Always use a sharp tool in order to work efficiently.

Checking for wear on the tool shank

Use the gauge that corresponds to the insertion tool's
shank dimension. See section "Technical data" for
correct tool shank dimensions.
The moil point is only used for
making holes in concrete and
other types of hard materials.
The wide bladed chisel is used
in soft materials, such as
asphalt and frozen ground.
