Checking the exhaust system for leaks
Check the exhaust system for leaks and security (formation of cracks).
If the inspection is carried out when the engine is warm, there is a risk of burns at the exhaust
system.
If the exhaust system is leaky or loose, the excavator may only be taken into operation after the defects
are eliminated.
Checking the oil level of the hydraulic system
To exactly assess the oil level, all hydraulic cylin-
ders have to be extended half way (see figure), the
boom has to be in line with the excavator, the dozer
has to be lowered to the ground and the extendable
track width has to be set to standard track width.
Check the oil level in the sight glass (1). The oil level should
be half way up the sight glass. Carefully check the position
of the hydraulic cylinders again before topping up. For more
information, see the "Topping up hydraulic oil" section
(page 91).
