COOLING SYSTEM
Always check the coolant level before operating and
add more coolant if needed. The radiator cap and
coolant ll cap is located on top of the of the paver.

• Wash out the radiator with a low-pressure water hose
ONLY when the engine is cool as needed.
• Check radiator hoses and clamps every six months for
leaks or damage, ensuring hose clamps are securely
tightened. If radiator hoses are swollen, hardened or
cracked, replace them immediately.
Plugged or dirty radiators and oil
coolers will cause engine or hydraulic overheating.
Damaged radiators hoses or coolant leaks also
cause overheating.
Replace radiator hoses and clamps
every two years, or sooner if needed.
If the coolant temperature warning icon illuminates, or
steam emits from the radiator or overow pipe, turn off
the load but idle the engine at least ve minutes to
cool down gradually and check the following items:
• Inspect for any coolant leaks, obstacles or debris
around the air inlet or outlet, dirt or dust between
radiator ns and tube, or clogged water pipe.
• Check the fan belt as described in previous section.
• Check that radiator cap is properly tightened. A gap
between the cap and seal accelerates coolant loss.
• Check for any internal blockage in the radiator hose. If
scale forms on the hose, clean with scala inhibitor (or
equivalent).
• Check engine cooling fan for damaged or bent blades.
Replace if damaged.
DPF ServiceDPF Service
The DPF (Diesel Particulate Filter) is designed to burn
trapped particulate matter automatically or via operator-
induced regeneration. The longer the DPF runs, the
more ash (burnt residue) is collected on the lter. Too
much residue adversely affects DPF performance,
therefore, see your authorized dealer for professional
cleaning (or replacement) if needed.
Do not be alarmed if you notice white exhaust from the
exhaust pipe at start-up or when speeding up. White
exhaust or water may come out during cold weather or
after long-hour idling due to condensation.
If DPF regeneration occurs frequently, i.e., ve hours
or shorter, on a routine basis, change the oil. If this
condition continues after an oil change, contact your
authorized dealer for service. (Refer to your Engine
Operator’s Manual for service information.)
Don’t idle machine any longer than
necessary as too much idling can cause soot to build
up in the Diesel Particulate Filters (DPF), requiring
more frequent regeneration.
To reduce the amount of soot and
maximize DPF efciency, use API-CJ4 (or ACEA-E9
European equivalent) engine oil. Running the
engine at 1800 RPMs will also provide more efcient
operation and allow automatic regeneration more
efciently while paving.
