REMARK
• It is recommended to use a nozzle having a diameter and a length specified by ISO 22241-4 and an auto
stop function to add DEF. When the specified nozzle is used, the magnet installed inside the filler port of the
tank cancels the wrong fluid addition prevention device, and you can add DEF. This mechanism prevents
addition of DEF into the fuel tank, addition of fuel into DEF tank, and spill of DEF from the filler port.
• When using a nozzle which is not conformed to ISO 22241-4, hold it in your hand and add DEF carefully
while checking the sight gauge.
• Add only DEF in clearly marked DEF tanks that have the blue cap.
METHOD FOR CHECKING TIRE PRESSURE
Measure the inflation pressure with tire pressure gauge while the tires are cool, before starting work.
Check the tires and rims for damage or wear, check the hub nuts (bolts) for loosening.
Proper inflation pressure varies with the contents of work, etc. For detail, see “TIRE PRESSURE”.
METHOD FOR CHECKING WINDOW WASHER FLUID SPOUTING OUT
Operate the window washer and check that the washer fluid spouts out normally.
• If the fluid does not spout out normally, clean the washer nozzle hole with a fine wire such as a safety pin.
• If the condition does not become normal, ask your Komatsu distributor to perform inspection and repair.
METHOD FOR CHECKING WIPER FUNCTION
Operate the wiper in the “Intermittent”, “Low”, and “High” mode and check that it operates and wipes normally.
• Operate the window washer to wet the glass, and check the operation of the windshield wiper.
• If the wiper does not wipe normally, the glass needs to be cleaned or the wiper blade needs to be replaced.
• If the condition does not become normal, ask your Komatsu distributor to perform inspection and repair.
