locking/unlocking lever 180°
counter-clockwise direction.
(FiG. 5).
Follow the same procedure for any
change of chisels.

of the breaker, it is possible
that the oil drains of the chisel
along the fixation system. this

- In some cases, it may be
necessary to hit the tip of the chisel
on the work surface in order to start
the percussion. This simply means
that the mechanism anti-impact
safety guard is working.
In other cases, for example in the
case where the material is very hard
to be demolished, it is necessary
to drill small holes to weaken the
material.
- Avoid overloading the engine by
pushing too hard the hammer onto
the surface to demolish. The force
applied to the hammer must not
affect the speed and impact force.
helP For Start
Sometimes, the demolition hammer
can not make impact movements,
although the electric motor
is running correctly, in particular
when the machine was stored
at temperatures below 10 °C.
This may be due to the fact that the
oil became very thick.
Work with the hammer for a few
minutes until it engages the drum
of the machine, to heat the interior
of the machine and make the oil
more fluid.
