REFUELLING PUMP
When adding fuel, never spill the fuel or let it overflow. It will cause a fire.
If any fuel has spilled, wipe it up completely. If the fuel has spilled over soil or sand, remove that soil or
sand.
Fuel is highly flammable and dangerous. Never bring flames near fuel.
Ensure that the machine is parked on level ground during refuelling operation.
Do not leave machine unattended during refuelling and monitor.
Following any over filling or spillage of fuel, inspect machine to ensure no fuel remains near electrical
or high temperature components.
Do not run refuel pump dry. Monitor fuel level in barrel during refuelling to prevent pump running dry.
The fuel pump is protected by an in-line blade fuse. If the pump fails to function - check the fuse.
Ensure the strainer on the hose end is clean.
When not in use, fully close the hose strainer valve cap to prevent leakage or spillage.
If there is any malfunction of the refuel automatic shut-off system, consult your Komatsu distributor and
do not use the system until the problem is rectified.
