Basic
Preventative Maintenance For Class 80800 Machines
Union Special Corporation’s
Class 80800 bag closing sewing machines close bags filled with
grains, pet foods, outdoor products and many other miscellaneous
products.
However, Class 80800 machines
do not have an automatic enclosed lubrication system. As a result, it
must be lubricated by hand. Following are the proper procedures for
maintaining this rugged, reliable equipment.
-
The machines have
to be cleaned and lubricated at the points indicated on Figure
1 twice a day, before morning and afternoon start. The
sight feed oiler has to be refilled before 2/3rds of the oil is used
up. For lubrication we
recommend "Mobil Oil DTE Medium" or Spec. 175, Mobil Oil
Prorex 39 which can be purchased from Union Special Corporation in 1
pint containers under part number 28604R, or in 1 quart containers
under part number
28604S. Before
operating a new machine for the first time, the needle bar guard, E,
Figure 1, and the sight feed oiler, which are two of the
accessories that come with the machine, have to be screwed in. The
sight feed oiler has to be adjusted. And all lubricating points
indicated on the diagram, Figure 1,
have to be oiled. For
adjusting, fill the sight feed half way with oil and turn the
metering pin, A, Figure 1, a
little bit out. Then turn it in until you get an oil flow rate of
approximately 2 drops per minute. This can be checked on the sight
glass, B, Figure 1, Secure the
setting of the metering pin with lock nut, C,
Figure 1. Fill the oiler.
Repeat oiling of a new machine after 10 minutes of operation.
