Gearbox
The hydraulic oil in the
gearbox has the same specifi-
cation as the engine oil.
When you change to hydraulic
bio-oil, drain the previously
used oil and purge twice.
Allow the gearbox to cool
down before you start mainte-
nance work. The temperature
during maintenance work
should not be higher than
51° C.
Check the
gearbox oil level
before each
startup and after every
25
operating hours - oil
dipstick and oil-filling orifice (1). With the ma-
chine in a horizontal position, the oil level must
be between the
max.
and
min.
marks.
•
Unscrew the oil dipstick, wipe it with a clean
cloth, and screw it back in.
•
Unscrew the oil dipstick and check the oil
level. Top up oil if necessary (refill volume
between min. and max. = 1 l).
Change the gearbox oil
after the first
50
operating hours and then after every
200
operat-
ing hours.
•
Tilt the machine forward on the connecting
flange.
•
Unscrew the oil filter (5) and replace it. Mois-
ten the sealing ring of a new filter with oil.
•
Dispose of the used oil filter properly.
Change the gearbox oil oil
and the oil filter
after the first
50
operating hours, and afterwards
every
600
operating hours when the oil is at
operating temperature.
•
Thoroughly clean oil filler plug (1) and oil
drain plug (4) and their environment to pre-
vent dirt from getting into the gearbox.
•
Open the drain plug, collect the used oil in a
suitable container, and dispose of it proper-
ly.
•
Clean the drain plug. It is equipped with a
magnetic core that attracts metallic particles.
•
Check the sealing rings (2) and (3). Replace
them if necessary.
•
Screw in and tighten the drain plug with
sealing ring.
•
Fill in fresh gearbox oil up to the "max."
mark.
•
Oil filing volume and oil grade see "Tech-
nical data".
•
Close the filling hole with the plug/dipstick.
