The IC-280 is factory filled with hydraulic oil for the -l5° to 110°F (-26° TO 43°C) range. If signif-
icant portions of time are spent operating below 20°F (-7°c) or above 100°F (43°C), the oil
should be replaced with an extreme temperature oil.
The oils shown are compatible with and may be combined with SAE 10W or SAE 20W-20 motor
oil, if it is necessary to add oil between changes, and the recommended oils are not available.
These motor oils are not suitable substitutes when changing hydraulic oil because they lack cer-
tain additives that are needed for hydraulic system use.
C A U T I O N
Never add kerosene or other “thinners" to hydraulic oil. These fluids have low aniline
points and consequently will cause rapid deterioration of certain packings and seals in
the hydraulic system.
C A U T I O N
Serious damage to the pump will result if it is run with the shut-off valve closed or with
insufficient oil level in the reservoir.
Observe the operation of the machine. If the oil is too cold, the machine will be sluggish and
should be warmed up further to prevent damage before sustained hard work is attempted. If the
oil is too hot, leakage will increase, pump efficiency will go down, and moving parts will not be
properly lubricated. If operating temperature is excessive, rapid deterioration of the oil will result
and moving parts and seals will wear more quickly. The cause of the excess heat should be
determined and corrected. A possible indication of excessive oil temperature is a control valve
lever that becomes hard to operate, or sticks instead of returning to NEUTRAL.
