Pfaff 463 User Manual

Since the use of sealed-fcr-IIfe bearings does not require the machine to be
oiltight, the incorporation of various feeding mechanisms can be easily
accomplished. This feature opens a practically unlimited Fteld of application
to this high-speed sewing machine.
The incorporotion of sealed-for-life boll ond needle bearings requires the use
of 0 reservoir oiling system merely for the sewing hook. From o reservoir built
into the machine arm, oil is fed to the sewing hook through a plastic oil tube.
The oil flow is controlled by shut-off valve V which is built into the oil tube.
When the machine is running, the stud of centrifugal switch F on the hook
shaft actuates the valve stem and opens hook lubrication shut-off valve V. The
same valve prevents oil from seeping out when the machine is inoperative.
The oil level con be inspected through the oil sight glass. If it is below the mark
on the oil sight glass, the reservoir should be refilled by inserting the spout of
an ordinary oil can into the small hole v above the oil sight gloss.
The flow of oil to the sewing hook con, in addition, be regulated by screw w
(Fig. 8). Turn this screw in for less oil, or out, for more oil.
The correct setting con be obtained through the following test:
Remove needle plate and feed dog and place a sheet of paper over the open
ing. Run the machine for about ten seconds. The setting is correct if two thin
lines of spray oil have appeared on the paper. Adjust the flow of oil at screw w
to suit special operating conditions (Fig. 8).
