MODEL 66-80 VIBRATORY DRIVER/EXTRACTOR
IV. MAINTENANCE AND ADJUSTMENTS
G. LUBRICATION (CONTINUED)
New power units are shipped with CHEVRON Clarity AW46 hydraulic oil. This oil
exceeds the requirements of both the E.P.A. and U.S. Fish and Wildlife Service for
non-toxicity and is inherently biodegradable. Adding any other oil from the list that
follows, will contaminate the Clarity oil and the system will no longer be
environmentally friendly.
Should the customer choose to use an alternate oil, the following
recommendations may be used when replacing oil in the hydraulic system. (See
page IV-6)

Whenever oils from the second preference group are used, it is necessary to test
the oil more often to insure that viscosity remains within recommended limits while
in servJ&M. Using oils from the third preference group requires even a more
discerning inspection than use of oils from the second group. Third Group oils may
be used when temperature variations are less than those listed below.
The recommended oils were chosen based on the hydraulic system operating
temperature range being 5°F (-15°C) (cold ambient start-up) to 160°F (71°C)
(maximum operating).
