7. Remove the cover film from the Teflon fabric belt. Stick the Teflon fabric belt
over the silicone rubber and the strip heater.
8. Insert the sealing bar into the machine and install the wiring.
Lubrication
Only if the appropriate lubricant is applied and the lubrication intervals are kept,
can the lubricant meet the requirements (good lubricating film, reduction of wear
and tear, corrosion protection, noise absorption, heat emission, sealing etc.).
This contributes considerably to achieving a good performance, reducing failures
and ensuring an adequate service life of the machine.
Synthetic lubricants must not be mixed with mineral ones!
In general, fixed intervals for changing the lubricant and relubrication cannot be
indicated as they depend on different factors. The respective operating condi-
tions such as ambient conditions, operating time and load are decisive.
Quality and quantity of the lubricant required in case of a change of lubricant are
indicated in the table of lubricants. Usable lubricants are indicated in the operat-
ing instructions of the respective manufacturers included in the annex.
Change of lubricant of geared motors
The geared motors are filled with the indicated lubricant at the factory. The inter-
vals for changing the lubricant are indicated in the manufacturer's operating in-
structions.
Before commissioning, pay attention to the manufacturer's operating instructions
and the information on the rating plate!
Anti-friction bearings
The machine's anti-friction bearings are supplied completely assembled includ-
ing grease filling. The maintenance intervals for the anti-friction bearings differ
from each other, depending on the number of revolutions, ambient temperature,
loads etc. The respective intervals for check and lubrication are indicated in the
inspection list.
Under normal operating conditions, the Y-bearing units are maintenance-free.
They should be re-greased in case of high humidity and excessive dirt. Due to
the operating conditions varying from case to case, fixed relubrication intervals
cannot be indicated.
Before relubrication, the lubrication point must be cleaned thoroughly. The
grease should be pressed in slowly until fresh grease comes out of the bearing.
Excessive pressure may damage the seal.
For changing the grease, the anti-friction bearings and the housing are to be
cleaned with a slightly volatile solvent or petroleum. When refilling, it must be
ensured that only 1/3 of the cage's and casing's space is filled with the recom-
mended anti-friction bearing grease (according to the lubrication instructions). A
