HYDRAULIC SYSTEM SERVICING
HYDRAULIC FLUID LEVEL CHECK
Gain access through the panel located aft of the wing fairing (on both
sides of the aircraft). On the hydraulic fluid level indicator, make sure
the needle pointer is between the 4.5 and 5.5 liter marks (normal
range). The shaded region is the dispatchability range. If the pointer is
below the refill mark, fill the reservoir until you have the correct full
level mark. Low oil level in the reservoir can be a sign that there is a
leak in the system. After servicing the hydraulic system, close the
related hydraulic fluid reservoir access panel.
If level indicator is inoperative, it is still possible to check fluid level, but
a maintenance technician is required to do the job.
CAUTION: USE ADEQUATE GOGGLES AND RUBBER GLOVES
WHILE SERVICING HYDRAULIC SYSTEM. IN CASE
HYDRAULIC FLUID COMES IN CONTACT WITH THE
SKIN, FLUSH THE AFFECTED AREA WITH WATER. IN
CASE HYDRAULIC FLUID COMES IN CONTACT WITH
THE EYES, FLUSH THEM WITH WATER AND SEEK
MEDICAL ATTENTION.
