INSTALLATION AND REMOVAL OF THE DEMOLITION HAMMER
INSTALLATION
For the installation of the demolition hammer it is necessary to connect
the mechanical constraints of the backhoe bucket as described in:
“CHANGING THE BACKHOE BUCKET” on page 2-41. To carry out
hydraulic connections, proceed as follows:
1. Stop the engine and neutralize all the hydraulic controls to relieve
all pressure in the system.
2. Press the hammer control pedal to release the pressure in the
hydraulic piping for the hammer.
3. Remove the cap plugs from the hydraulic piping and hoses.(use a
32, 36, 38 and a 41mm wrench)
4. Connect the right coupling and then the left coupling.Make sure the
connections all match
5. Be careful not to get impurities between the couplings when
installing them.
6. Once connected and tight, start the engine and raise the ham-
mer positioning it vertically.
7. Stop the engine and lubricate all points on the hammer.
8. Before starting work operations, check for any leaks.
.When removing or installing the hammer, always wear eye and hand protection. Before carrying our
removal or installation relieve all hydraulic pressure first
