SECTION IV
MODEL 560 OPERATING INFORMATION
OIL
Each engine oil tank has an oil filler neck with a cap assembly. Oil is added to each engine directly
through the filler neck and quantity is measured on the sight gage in U.S. quarts. An accurate check of oil
quantity can only be made when the engine is hot, within approximately 10 minutes after engine shutdown.
CAUTION
PERSONS WHO HANDLE ENGINE OIL ARE ADVISED TO MINIMIZE SKIN
CONTACT WITH USED OIL, AND PROMPTLY REMOVE ANY USED OIL FROM
THEIR SKIN. A LABORATORY STUDY, WHILE NOT CONCLUSIVE, FOUND
SUBSTANCES WHICH MAY CAUSE CANCER IN HUMANS. THOROUGHLY WASH
USED OIL OFF SKIN AS SOON AS POSSIBLE WITH SOAP AND WATER. DO NOT
USE KEROSENE, THINNERS OR SOLVENTS TO REMOVE USED ENGINE OIL. IF
WATERLESS HAND CLEANER IS USED, ALWAYS APPLY SKIN CREAM AFTER
USING.
BP TURBO OIL 2380, EXXON TURBO OIL 2380, CASTROL 5000, AEROSHELL TURBINE OIL 500,
AEROSHELL TURBINE OIL 560, ROYCO TURBINE OIL 500, ROYCO TURBINE OIL 560, MOBIL JET OIL
254 and MOBIL JET OIL II are all approved oils. Normally different brands of oil should not be mixed;
however, if oil replenishment is required and oil of the same brand as tank contents is not available, follow
procedures set forth in Section I of this manual under OIL. The type of oil used in each airplane is noted in
the engine logbook as well as on a placard inside the filler access door.
The latest revision of Pratt and Whitney Canada Inc. Service Bulletin 7001 may also be consulted for
approved oils.
HYDRAULIC
Servicing the main hydraulic reservoir requires equipment capable of delivering hydraulic fluid under
pressure and is normally performed by maintenance personnel. The reservoir should be serviced with one
of the approved fluids, SKYDROL 500A, B, B-4, C or LD-4; or Hyjet, Hyjet W, III, IV, IVA, or IVA Plus.
The hydraulic brake reservoir can be serviced by removing the right baggage compartment aft liner to
allow access to the reservoir. The filler plug can then be removed and the reservoir filled to within one-half
inch of the opening. The brake reservoir should be serviced with one of the approved fluids, SKYDROL
500 B or equivalent.
OXYGEN
The oxygen filler valve is located just inside the access door in the tailcone compartment. Oxygen
servicing should be done by maintenance personnel using breathing oxygen conforming to MIL-O-27210,
Type I. Refer to the cockpit gage while servicing to prevent overfill.
Oxygen pressure will vary with ambient temperature. In very cold ambient temperatures the oxygen
pressure indication may appear low, but may in actuality be appropriate for the temperature condition.
NOTE
Refer to Chapter 12 of the Airplane Maintenance Manual, Oxygen Service
Requirements, Pressure Variations Chart.
