themselves and the upper part of the boom as shown in the photo.
• COOLING SYSTEM
If you need to replace the engine cooling liquid, proceed as follows:
DISCHARGE OF THE COOLING SYSTEM
-
Place the machine on a flat surface
-
Stop the diesel engine and let it cool off
-
Using a strong piece of cloth, loosen pressurised cap "B" and release the
system pressure.
WARNING!
Never remove the pressurised filling cap "B" if the diesel engine is still hot,
as the cooling liquid, still under pressure, could flow out in a dangerous
manner.
Also, make sure that, during the system discharge/filling phases, the
cooling liquid does not get in contact with any body part. Always refer to
the information on the used product label.
To use the machine in maximum safety conditions, always use the supplied
pressurised cap. If this is lost or damaged, contact Merlo Technical
Support Service and request it as a spare part.
-
remove clamp "C" and disconnect duct "D" from the radiator
-
remove drain plug "E" of the engine block located in the inner part of the
engine compartment.
-
drain the system completely
-
check the duct and clamp wear level; if necessary, replace them (it is
advisable to perform a visual inspection of both ducts and clamps every 500
hours to check for any sign of wear)
-
if necessary, rinse the system with clean water mixed with a detergent
FILLING UP OF THE COOLING SYSTEM
-
close drain plug "E" of the engine block
-
put in place duct "D" and tighten its clamp "C"
-
slowly fill the cooling system (use the coolant shown in the engine manual)
until the coolant is visible inside expansion tank "A"
-
the level inside expansion tank "A" shall fall within the "MIN" and "MAX"
marks shown on the indicator plate
-
close the expansion tank with its pressurized cap
-
start the Diesel engine and let it run for a few minutes
-
check for any leak in the system
-
check that the coolant level always falls within the two marks shown on the sticker applied on the expansion tank; if this is
not the case, fill up coolant
NOTE! For further information, refer to the attached engine manual.
