Procedure Information
The air line lubricator automatically dispenses 10 wt. non-detergent oil into the compressed air used to operate the
system. This oil is carried via the air lines to all air cylinders, valves and seals for the purpose of lubrication. The sys-
tem will operate at peak performance when the oil rate is set to one drop dispensed for every 2 complete press cycles
with all print stations and indexer operational.
As Required
Tools required: 1 - Standard blade screw driver (small)
1. Turn “ON” all print stations. Start the press and allow the
press to run with all print stations and index system opera-
tional for 5-10 minutes. After the press has run for 5-10 min-
utes, observe the oil flow rate at the sight dome on top of the
air line lubricator assembly. A proper rate of flow will be 1
drop of oil for every 2 complete press cycles.
2. Should the oil flow rate require adjustment, use the small
standard blade screw driver and adjust the small red colored
metering screw on top of the sight dome for the proper rate
of 1 drop for every 2 complete press cycles. Turn the meter-
ing screw clockwise to decrease the oil flow rate. Turn the
metering screw counterclockwise to increase the oil flow
rate. (See top view illustration at right)
