5.2 Weekly maintenance
Check on the loosening of the hammer bolts.
It is advisable to check, at regular intervals, possible loosening of the bolts and particularly:
-
The screws fixing the head/bracket.
-
The screws fixing the flanges/hose joints.
5.2.1 Machine stop
a) Take down the tool in order to determinate possible
chippings or cracks in the bush and on the surfaces of
the pin for tool.
These marks are proof of insufficient lubrication, use of
unsuitable oil or improper use of the hammer.
With the help of a sanding disk, polish the trimmings that can
be seen on the surface between the tool and the retainer pin
for tool (see points B in the picture).
b) Check the wear of the retainer pin for tool; in the case of
excessive wear, invert the assembly or change it.
c) Check the wear of the tool bushings; if the inside diameter
is bigger than the value indicated in the technical
specifications, contact the technical assistance to change the
bushes.
Stop at the end of a work with a hot hammer
During the night, drive the hammer vertically into the ground,
so that the condensed water can easily be emptied through
the prominent part of the piston, thus avoiding oxidation.
Long term stop
When the hammer is disconnected from the excavator boom
and is left standstill for a long time, it is necessary to:
Remove the tool, push the piston (with a tube) as higher as
possible, grease abundantly and re-install the tool.
This operation prevents the piston terminal from rusting.
Keep the hammer in a close place sheltered from bad
weather.
