OIL LEVEL
The oil level should be checked when the vehicle is first
purchased and then once every two years. More often if
there is an oil leak in the system.
All jacks and any HWH room extension cylinders should be
completely retracted before checking the oil level. The oil
reservoir is part of the pump/manifold assembly. The oil level
Most breather caps have a dipstick.
NOTE: Overfilling the tank can cause leakage of oil
through the breather cap.
