e) LUBRICATION AND CLEANING OF MACHINE
1) Head ball bearings (fig. 15) are the r.lost delicate part of the ma
chine and require a special care.
Lubrication is to be carried out on each ball bearing housed in the
mobile cylinder through the two lubricators (A), by means of the
appropriate grease gun, squeezing twice against the lubricating
holes.
Eccessive grease causes overheating of ball bearings during first
revolutions: spontaneous overflow reduces temperature to normal
values.
A part from the intervals we have already mentioned, ball bearings are
to be gr:J:Jsed whenever they overheat.
For this operation it is suggested to use the special ESSO BEACON
325 grease for high speed ball bearings.
2) Cyl inder jacket (fig. 16)
Is to be lubricated with normal "Stauffer" grease by filling and then
by squeezing the lubricator (A).
CAUTION: when the machine is still cold, the cylinder's friction is over
normal values, but after approximately ten minutes running it becomes
smooth again.
3) Air lift (fig. 17)
Lubrication is to be done with the appropriate oil gauge (A) located
at the air inlet.
Check the oil level and eventually restore it with 3" Engler oil at 50·C
Make sure that the drops fall at a rate of one every 5 strokes of the
cylinder.
For the eventual adjustment of the drops' fall, operate the screw (B) .
