Never drive the chisel into the ground:
If the advance is too large and the chisel is not rocked to release the
dust, the chisel will be driven into the material without breaking the
material. This causes the chisel tip to glow red-hot and lose its hardness
As a result, the chisel wears out more quickly. Operating in this way is
not permitted.
Dust dampens impact power, when the chisel is inserted into the ground,
and reduces the efficiency of the hammer. Tilt the hammer slightly
backward and forward, not more than 5°, while operating so that the dust
can escape. Do not rock the hammer at angles greater than 5° or the
chisel will be broken.
Never use as a lever:
Do not use the chisel as a lever; e.g. crowbar, as this will cause the
chisel to break.
Under any circumstances, operating in this way is not permitted.
Most of bending failure of the chisel may be caused by lever action in
stone that is inside hard or frozen ground. Be careful and stop operating
if you feel sudden resistance under the chisel.
Never use for transport purposes:
The hydraulic hammer is not designed to lift or transport loads. Never
use the chisel as a lifting point.
This is dangerous and could damage the hammer or the chisel.
