ambient temperature requirement.
Chassis grease
Grease added in each part should use 2
#
lithium base lubricant (suitable for temperature within the
range of -30~ +120
℃
).
Vehicle with centralized lubrication should use 0# lithium base lubricant.
Water tank coolant
Long life anti-freezing and antirust fluid should be added to water tank. The coolant could be general
used both in winter and summer without adding and draining water in winter and it can prevent forming scale
and corroding cooling system. Freezing point of the coolant should be noticed to 5
℃
lower than the lowest
environment temperature. Different type of coolant should not be mixed using.
Replacing period of the coolant is 2 years.
For specification of the coolant please see the section "filling up coolant” in the chapter "maintenance and
