OPERATION
OPERATING TECHNIQUES & PRECAUTIONS
PRELOAD THE TOOL BEFORE
STARTING
Press the tip of the demolition tool
vertically against the object to be broken.
Be sure the object is stable before
activating the NPK HYDRAULIC
HAMMER.
APPLY DOWNFORCE ON THE
TOOL
Raise (
104
) the front of the machine
slightly by applying down force on the
demolition tool.
Press the control lever or the foot pedal to
start the NPK HYDRAULIC HAMMER.
Applying excessive force to the hammer
will raise the carrier too high and jolt
the operator when the material breaks.
Let the NPK HYDRAULIC HAMMER do
the work.
AVOID BLANK HAMMERING
As soon as the material is broken, release
the control lever or pedal to prevent
unnecessary blank hammering.
Blank hammering is continued hammer
operation after the material is broken.
This will overheat the hydraulic system,
cause undue wear, and result in
eventual tool retaining pin failures, see
page 33.
