Stop Immediately When
․ The Hydraulic Hoses Jerk Violently.
Abnormal surging means the nitrogen
accumulator is empty. Stop the hammer
immediately and repair the accumulator.
․
The Tool Does Not Drop.
If the visible length of the tool does not
change, it usually means the tool has seized
in the bushing. Remove the tool and check
the bushing. If obvious signs of seizing are
present, remove the marks from the tool
and bushing or replace as necessary. Then
clean and lubricate the shank for installation of the tool.
․
Tension Bolt is Loose Or Broken.
Tighten it properly or replace it. You can tell if it is broken or loose by tapping on the
bolt and listening for a distinctive high pitched sound.
2. Rules to Remember
1) Avoid Blank Hammering At All Times.
If this happens, the piston will strike the
tool shank with full impact, forcing the tool
against the retainers and causing premature
wear and failure to the tool, tool retainers,
piston, chuck housing, tension bolts and the
hammer itself. And since there is no material to
absorb the energy, the shock waves will bounce
back up the tool, meeting other waves coming
down the tool in violent collisions. These collisions create a disorganized mass of energy,
causing extensive wear and tear to the tool and other hammer components.
