SAFETY Accumulator This machine is equipped with an accumulator charged with high-pressure nitrogen gas. Before servicing the accumulator, observe the following precautions: Do not dissemble the accumulator. Do not expose the accumulator to high heat or an open flame. Do not weld on the accumulator. Do not drill or cut the accumulator. Do not strike or crush the accumulator. When replacing or disposing of the accumulator, always release the nitrogen pressure from the chamber. Critical Parts Periodically some parts must be replaced due to safety purpose.
Even if these parts seem to be in good condition and operating properly they may fail at some point causing possible injury to the operator or pedestrian. Listed are some of the systems containing these components that may fail under extended use: Seat belts. Fuel supply and delivery hoses. Hydraulic system: main delivery hoses and tubing. Hydraulic hoses: all the hoses that feed and return the hydraulic fluid to and from the work equipment. For additional information: See “WEAR PARTS LIST” on page 3-8.
High Voltage When the engine is running or immediately after it has stopped, high voltage is generated at the injector terminal and inside the engine controller, so there is danger of electrocution. Never touch the injector terminal or the inside of the engine controller. If it is necessary to touch the injector terminal or the inside of the engine controller, please contact your Komatsu distributor.
