The green zone indicates that hydraulic fluid is properly filtered and flowing unrestricted through
the filter and head assembly back to the reservoir. As the filter traps harmful debris and contaminants,
the indicator will move into the red zone.
When the indicator is in the red zone, it is indicating filter is clogged and fluid is bypassing the ele-
ment to return to the reservoir. The filter head is equipped with a built in bypass valve to prevent a
clogged filter from developing a leak due to excess hydraulic fluid pressure inside a clogged filter.
The filter is rated at ten micron*. Change the filter before the built in sight gauge is operating in the
red zone. This will ensure the hydraulic fluid is properly filtered.
Filter number: Parker IN HC 5720 (ten micron)
*One micron is one millionth of one meter.
Hydraulic Reservoir
The hydraulic reservoir, located in the engine compartment, is made from aluminum so the tank
will not be affected by moisture that may condense. The oil level in the reservoir should be checked
when the hydraulic fluid is at operating temperature. This should be done every 6,000 miles or three
months. The oil dipstick/oil fill is located on top of the reservoir. The oil level should be kept between
the full and add marks on the dipstick. When performing fluid level checks, inspect fittings and hoses for
signs of leakage. Look underneath the motorhome for signs of fluid leakage. Avoid untimely and costly
failures by having leaks repaired. Change the hydraulic oil filter every 15,000 miles or once a year.
NOTE:
Use Dexron III
®
transmission fluid when adding oil.
