VISCOSITY: Oils are available in various grades (vis-
cosities). The ISO (International Organization for Stan-
dardization) viscosity classification system is currently
being adopted. The ISO grade applies strictly to vis-
cosity and does NOT imply type of oil. (engine, anti-
wear, hydraulic, gear.etc.). A viscosity grade should be
selected that will meet the minimum start up tempera-
ture requirement and the maximum operating hydrau-
lic oil temperature.

HYDRAULIC OIL (Initial Fill)
KOEHRING SPEC 805 DATA
This machine is factory filled with Koehring spec
805 hydraulic fluid that is acceptable for start-up
at ambient temperatures of 20°F and should not
be operated above a hydraulic reservoir temper-
ature of 200°F. If these limits are exceeded dam-
age can result. For operation outside these
ranges, select the proper hydraulic fluid from the
charts on this and the following pages or from a
reputable supplier.
