Note: Oils within this group are inter-
changeable.
IMPORTANT: Two groups of hydraulic oil are
specified to allow optimal operation of the
machine in a wide range of temperatures
encountered. The group 1 oils are a multi-
viscosity hydraulic oil that allow operation at
lower temperatures without the increased
viscosity associated with straight viscosity oils.

temperatures may result in decreased efficiency in
some hydraulic components compared to using the
Mobil DTE 26 type oils.
The Mobil DTE 26 type oils are straight viscosity
oils which remain slightly more viscous at higher
temperatures than the multi-viscosity oils.
Using the Mobil DTE 26 type oils in the lower
ambient temperatures may result in harder starting,
increased engine laboring while cold, sluggish or
non-operating valve spools while cold and increased
filter back pressure due to the higher oil viscosity.
Select the set of conditions (either ambient
temperatures above 21° C or below 38° C, and use
that type of oil throughout the year, rather than
changing oil types several times per year.
Group 3 Hydraulic Fluid (Biodegradable):
ISO VG 32/46 anti-wear Hydraulic fluid
Mobil EAL 224H
Note: This biodegradable hydraulic fluid in this
group is not compatible with the fluids in group 1 or
2.
Note: When changing from one type of hydraulic
oil to the other, remove all the old oil from the
system, because some brands of one type are not
completely compatible with some brands of the
other type of hydraulic oil.
IMPORTANT: Use only the types of hydraulic
oils specified. Other fluids could cause system
damage.
1.
Position the machine on a level surface, lower
the cutting units and stop the engine.
2.
Clean the area around the filler neck and cap of
the hydraulic tank. Remove the cap from the
filler neck.
3.
Remove the dipstick from the filler neck and
wipe it with a clean cloth. Insert it into the
filler neck; then remove it and check the fluid
level. It should be within 6 mm (1/4 inch) of
