MAINTENANCE PROCEDURES
AB18EJ&18HJ Maintenance Manual 5-11 © Oct 2020
NOTICE
• Do not apply sealing additive to the cooling
system, otherwise it will cause blockage to the
low-fludity area, radiator and engine oil cooler, or
damage the water pump sealing.
• Do not apply soluable engine oil to the cooling
system, otherwise it will corrode the brass and
copper, damage the surface of heat exchanger,
sealings and hose.
• The water added into the coolant must meet the
requirements of calcium and magnesium less
than 170ppm and sulphur less than 100ppm.
Excessive calcium and magnesium can lead to
scale formation, and excessive chloride and
sulfate can corrode the cooling system.
A-10 Inspect Engine Belt (AB18HJ
only)
Maintaining the engine belt in good condition is vital to
good machine performance and service life. The
machine should not continue operation with the engine
belt being loose or deficient, or it will result in
component damage.
NOTICE
Shut off the engine before inspection.
Inspect the engine belt for：
• Crack or breakage
• Wear or misalignment
• Peeling-off
• Glazing or hardening
• Improper tensioning (press at the middle position of
the mostly extended belt between the pulleys to
check the tensioning condition, the press-down of
belt should not exceed 13mm [0.5 in.].)
