Maintenance
Replace Radiator Hoses Replace Radiator Hoses
Radiator hoses should be replaced if worn or frayed.
Access the radiator from the top access panel.
NOTE: Inspect the radiator and oil coolers daily. If
needed, wash out using a low-pressure water
hose once the engine has cooled down.
Dirty or plugged radiators and oil
coolers will cause engine or hydraulic overheat
conditions.
This procedure should only be
performed when the machine is not running.
DO NOT remove the radiator cap while
the engine is still hot. The radiator is under pressure
serious injury can occur if removed while hot.
1. Raise the hood following instructions on Page 5-5.
2. Turn off ignition, remove key, and allow the engine to
cool down.
3. Carefully remove the radiator surge tank cap.

Fuel System
Fuel TankFuel Tank
The fuel level is indicated on the digital display fuel
gauge. Use only low-sulfer diesel fuel and always ll the
fuel tank at the end of the work day to prevent conden-
sation. The green fuel cap is located on the left side of
the paver. (Figure 5-24)
Fill up with low-sulfer diesel fuel at the
end of the day to reduce condensation in the tank.
Diesel fuel is highly FLAMMABLE.
DO NOT smoke while lling the fuel tank. Fill the
fuel tank in a designated area that provides proper
ventilation with a re extinguisher available.
Explosion Hazard! Never ll the fuel
tank near an open ame, or near equipment that can
create sparks. Never check fuel level or fuel system
components near an open ame.
