REPLACE FUEL MAIN FILTER CARTRIDGE

After the engine has been operated, all parts are at high temperature, so do not replace the filter immediately. Wait for all parts to cool down before starting the operation.

High pressure is generated inside the engine fuel piping system when the engine is running.

When replacing the filter, wait for at least 30 seconds after stopping the engine to let the internal pressure go down before replacing the filter.

Do not bring any fire or flame close.

Genuine Komatsu fuel filter cartridges use a special filter that has highly efficient filtering ability. When replacing the filter cartridge, always use a genuine Komatsu part.

The common rail fuel injection system used on this machine consists of more precise parts than the conventional injection pump and nozzle.

CHECK, REPLACE STEERING A ARM MOUNTING BOLT

Check and replace the A arm mounting bolts, lock plate, and holder.

Please consult your Komatsu distributor when checking and replacing.

Warning: The parts and oil are at high temperature after the engine is stopped, and may cause burns. Wait for the temperature to go down before starting the work.
