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 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,
and cause undue wear of hammer parts,
and result in eventual tool retaining pin
failures, see page 54.
