Fill the Reservoir
Material Cleanliness
The lubricant used to fill the system must be clean. If
there is doubt about cleanliness, the lubricant should be
filtered before using in the system. System life and con-
sistent operation will both be improved by using clean
lubricant.
After filtering the lubricant, protect the lubricant supply
from debris.
On all pump packages, the lube piston diameter is very
close to the diameter of the chamber in the pump body.
Contaminants in the lubricant could cause scoring,
resulting in erratic pump operation and costly parts
replacement.
Temperature Effects
Flow characteristics of the lubricant may change due to
drastic temperature changes. Choose a lubricant that
flows properly at all temperatures expected in the sys-
tem environment.
Overhead Supply Adapter Assemblies Only
The recommended inlet pressure is 15 psi (0.103 MPa,
1.03 bar) or less.
Fill Oil Reservoir Model
The reservoir on oil models has a fill cap (30) and filter
screen (31).
1. Clean the area around the fill cup to avoid contami-
nation during filling.
2. Open the fill cap (30) and slowly pour oil into the
reservoir (11) through the filter screen (31).
NOTE: The filter screen (31) removes any large par-
ticles present in the oil.
3. When filling is complete, close the fill cap (30) and
clean up any spillage.
