4 Place the boom and hammer in the breaking
position. Quick and careless boom movements
could result in damage to the hammer.
5 Place the tool perpendicular to the surface of the
object. Keep the feed force aligned with the tool.
Avoid small irregularities on the object which will
break easily and cause either idle strokes or an
incorrect working angle. When demolishing
vertical structures (e.g. brick walls), place the
tool perpendicular to the wall.
6 Press the hammer firmly against the object. Do
not pry the hammer with the boom. Do not press
too hard or too gently with the boom.
7 Start the hammer.
Depress button (8) to activate the hammer
function.
Release the button to deactivate the hammer
function.
NOTE!
Listen to the sound of the hammer when you are
using it. If the sound becomes weaker and the
impact less efficient, the tool is misaligned with the
material and/or there is not enough feed force on
the tool. Realign the tool and press the tool firmly
against the material.
