Warning! The hammer must be secured from rolling over when disconnecting
from the carrier. Only use a skilled operator to position the carrier for hammer
removal!
Warning! Hydraulic pressure inside the hammer must always be released
before opening hose connections!
Warning! Hot hydraulic fluid can cause severe injuries!
1. Position hammer horizontally on the floor. If the hammer is going to service,
remove the tool.
2. Stop the carrier engine. Operate boom and hammer controls to release pressure
trapped inside hoses. Wait ten minutes for oil pressure to drop.
3. Close hammer inlet and outlet lines. If quick couplers are used, disconnection
automatically closes hammer lines. If hammer line includes ball valves, please
make sure that they are closed.
4. Disconnect hoses. Protect environment from oil spills. Plug the hoses and the
hammer inlet and outlet ports.
5. Remove bucket pins and other parts.
6. The carrier can be moved aside.
1. Install hammer in the same manner as mounting a bucket. Install bucket pins.
2. Connect hoses. Hammer inlet port is marked on the valve body with "IN" and
outlet port with "OUT". An installation inspection must be carried out after the
product has been mounted on the carrier. In the installation inspection certain
specifications (such as operating pressure, oil flow) are checked so that they are
within given limits. See “Hammer specifications” on page 66.
