4.9 Manual Bleed Valve
(Figure 15)
The manual bleed valve is used in small piston models where oil movement and hydraulic instabilities are
minimal. To operate this valve, loosen the valve a slight amount until the oil is seen coming out. Leave the valve
loosened for a few strokes of the pump and then retighten.
4.10 Lubricating Instructions
PULSAlube is a custom blend of oil with additives for lubrication and hydraulic transfer service (For emergency
requirements, a list of acceptable commercial oils is available). The diaphragm on the cover of the gear box
assembly generally protects the oil from contamination for extended periods of time. A periodic six month check
should be made for oil level and possible contamination.
Under sustained conditions of high humidity or if wear is present, the oil can become emulsified and take on a
yellowish color. Change the oil immediately if this occurs and examine the make-up valve and other parts for
corrosion. A suction pump similar to a grease gun is useful for removing oil from the chambers, or it may be
drained from the ports at the side of each chamber.
To establish a maintenance record and routine procedure, check lubricant and drive mechanism at three and six
month intervals. At the first six month interval check the condition of the inlet and outlet check valves. These
items along with oil seal inspection should be part of a routine service procedure.
