l Only trained mechanics should repair or disassemble the hydraulic breaker. Be sure you understand a service procedure before beginning any work; if you are uncertain, contact your RockAge representative.
l Avoid unauthorized machine modifications – never substitute alternate parts not intended for the application. This could create hazardous situations or machine failure. RockAge Engineering must approve all machine modifications; they can affect product reliability and machine stability.
l Before performing any work on the machine, attach a DO NOT OPERATE or similar tag in the operator`s tag in the operator`s cab to alert others of service work being performed. Remove
engine key and master key switch. Unexpected machine movement can cause serious injury.
l The cushion chamber (back head) is charged with nitrogen (N2)-a non-explosive inert gas. Only use N2 when refilling it. Charging it with any other gas could trigger an explosion and lead to serious or possibly fatal injuries.
l Relieve all gas pressure in the cushion chamber before beginning disassembly procedures to avoid the potential for accidents or injury. It remains under pressure even after the hydraulic system is depressurized. Refer to the Maintenance section of the manual.
l Stay clear of the tool when charging the breaker cushion chamber. Gas pressure may cause unexpected piston movement and force the tool to jump against the tool retainer pins.
l Use only lifting devices with sufficient capacity to safely support the expected weight you are
lifting.
l All lifting devices (straps, slings, chains, ratchet blocks, etc.) must comply with applicable local regulations and certifications. RockAge cannot accept responsibility for the use of sub- standard equipment and work practices.
l When lifting or supporting the breaker or its parts, use equipment with a sufficient lifting capacity.
l Use the lifting eyes or lifting points that are located on certain breaker components.
l Do not work under a hanging or suspended load!
l If a jack is used, the floor or ground must be flat and of sufficient strength to support the expected load.
