Warning: If hydraulic oil or grease is injected into the skin, it can cause
serious injury and death. Prevent your hands or body from approaching the
area of pressure oil leakage. Check for leaks with cardboard or paper. If
hydraulic oil accidentally injected into the skin, immediately seek for
medical attention.
Warning: To avoid burns, maintenance should be carried out only when the
hydraulic oil has cooled down or before daily work.
In order to prevent oil from spraying out, it is necessary to slowly rotate the
cover to release internal pressure when removing the fuel filler flange cover.
1. Check the oil level in the
hydraulic oil tank
Check the hydraulic oil tank level every 10
hours.
1) Park the machine on a level surface.
2) Start the engine to make each cylinder
reciprocate.
3) Retract the stick cylinder, extend the
bucket cylinder, and then the bucket falls
to the ground, the dozer blade shall be
placed on the ground and shut down. As
shown in the figure.
4) Observe the hydraulic oil level through
the oil gauge tube on the hydraulic oil
tank.
The liquid level of the hydraulic oil shall be
observed through the oil standard tube (as
①
in the figure).
The hydraulic oil level shall be clearly
seen on the oil leveler, and the oil shall not
be filled over much, otherwise the level
can not be seen through the oil leveler.
Since this may cause damage to the
hydraulic oil line or injection of oil. If the
refueling is too full, stop the machine and
drain the excess oil from the oil drain plug
