500 Series
7. Hydraulic oil level
Hydraulic oil tank ller is located on the front of the boom,
under a hatch.
Hydraulic oil level can be checked with the dipstick in
the ller. Lock the boom with the boom service support
to access the ller opening. Do not let any contaminants
enter the hydraulic oil tank when you open the ller cap.
Remember to use the service
support (page 30)
The oil level should be approximately at the lower mark of
the dipstick (1) when the loader boom is up.
Tighten the dipstick on its threads for measurement. Rell
when necessary, but never exceed the upper limit mark
(2). Overll can cause oil to overow when lowering the
boom.
1 Target marker. Fill to this
mark when hydraulic system
is cold.The area highlighted
in the adjacent gure shows
approximately the acceptable
level.
2 The second mark on the
dipstick indicates the max
level of hydraulic oil. Oil can
reach this level when the
hydraulic system is hot.
Never overll the hydraulic oil
tank. Oil can ow over, or foam
inside the tank.
There is a breather lter inside
the dipstick cap which should
be cleaned or changed once a
year.
8. Attachment and its locking
Check the locking of attachment and function of the
locking pins of the attachment quick coupling plate.
• Both pins must move and come through the lower
brackets of the attachments.
• To check the correct function of the attachment
and itsadditional coupling instructions, see the
Operator’smanual of the corresponding attachment.
Do not operate the loader if the coupling pins do not
lock down. Always keep the Operator’s manual of each
attachment available.
