Filling the Reservoir
Material Cleanliness
Make sure that lubricant used to fill the system is clean.
If there is doubt about cleanliness, lubricant should be
filtered before being introduced into the system. System
life and consistent operation will both be improved by
using clean lubricant.
After filtering the lubricant, make sure the lubricant sup-
ply is protected from debris.
On all pumps, the lube piston diameter is very close to
the diameter of the chamber in the pump body. Contam-
inants in the lubricant could cause scoring in this area,
resulting in erratic pump operation and costly parts
replacement.
Temperature Effects
Flow characteristics of the lubricant may change if the
area the unit is used in goes through drastic tempera-
ture changes. Choose a lubricant that will flow properly
at all temperatures expected in the system environment.
Overhead Supply Adapter Assemblies Only
The recommended inlet pressure is 15 psi (0.103 MPa,
1.03 bar) or less.
Filling Oil Reservoirs
Oil reservoirs have a fill cap (30) and filter (31).
1. Wipe 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) will remove large parti-
cles which may be present in the oil.
3. When filling is complete, close fill cap (30) and wipe
any spillage.
