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 service. Using oils from the third preference group requires even a more
discerning inspection than use of oils from the second group.
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).
When operating in arctic conditions, it is recommended to use an immersion heater
to pre-heat the oil prior to starting . Contact J&M for other arctic operating
procedures. It may also be necessary in extremely cold or hot climates to use a
different viscosity oil which is better adapted to adverse conditions. Contact the
nearest oil supply representative for suggested procedures.
CHEVRON Clarity AW46 hydraulic oil is available from J&M in five gallon cans.

K. DRAINING AND FILLING HYDRAULIC OIL RESERVOIR
1. The Hydraulic reservoir is drained by removing a plug on the bottom of the
reservoir.
2. The hydraulic reservoir is filled by the manual pump mounted on the back
(engine side) of the reservoir. All oil is pumped into the reservoir through the
return filter (F2) to insure no dirt enters the hydraulic system.
