When applying impact, push chisel against the
impact surface and operate so that the chassis
rises approx. 50 mm (2 in) off the ground. Do
not let the machine come further off the ground
than this amount.
Always keep the chisel pressed against the
impact surface properly to prevent using the
impact force when there is no resistance.
Adjust bucket cylinder at all time, always keep
chisel pushed perpendicularly against the
