EXPLODED PRODUCT VIEW, PARTS & ORDERING INFORMATION
Lubrication
Series 0823 and 1023:
These models use a constant level oiler. The
lubrication rate is determined by the temperature,
the vacuum or pressure at which the pump is
operating, and the siphon jar oil level
(determined by the vertical position of the tube in
the jar).
The lower end of the tube should be 1/4" from
the bottom of the oil jar for normal lubrication. To
reposition the tube, loosen the locknut and adjust
the sleeve up or down. Lock the new position
with the locknut. For faster lubrication, raise the
reservoir tube away from the bottom of the oil jar.
For slower lubrication, lower the reservoir tube
toward the bottom of the jar.
To replenish the oil, pull the reservoir upward out
of the adjusting sleeve and turn it over. Add oil
through the tube. When the upper reservoir is
filled, replace it through the adjusting sleeve and
firmly seat it against the top of the sleeve.
All Models:
The oil wick should be folded in half, with the two
ends submerged in the oil at the bottom of the
Jar, and the folded center inserted into the
connector approximately 3/8" past the two
breather holes in the connector (but not touching
the feed hole leading to the pump). Both the
breather holes and the feed hole must be
unrestricted.
