Weekly
a) Drain water from the Air Service unit (ASU) water filter.
b) Check welding bar for residues of polymer. clean with a piece of cloth while the
bar is hot. Should the bar need more frequent cleaning inspect the teflon
coating for damage. Replace if necessary.
Monthly
a) Check oil level in the ASU lubricator fill in with the recommended pneumatic oil.
If the oil consumption rate is faster check the screw adjustment for reducing the
dosing quantity. For slow operating machines (up to 5 packs per minute) the
feed should be 1 drop/15 operations. Machines operating at a faster rate
should receive 1 drop/40 operations. As a starting point for oil feed adjustment,
turn the adjusting screw clockwise to the end, then back off 1.4 to 1/2 turn.
b) Un-clip the Anvil Bar and check teflon shield as well as the silicon rubber strip
for signs of wear or damage. In most cases there will be remains of
polyethylene film if the teflon has worn of from the fibreglass substrate.
c) Remove the pusher assembly cover and lubricate the pusher linear bearings
with machine oil.
d) Check all film rollers for free spinning in order to keep the tension and free
movement on film pathways.
Every 3 months
a) Inspect the cutting edge of the knife for any damage and teflon coating.
Replace if such is evident.
Note! Maximum life expectancy is 6 to 12 months.
b) Unclip the anvil bar and change the teflon shield. Inspect the silicon rubber strip
if it has a deep (1mm) grove along the centre change the same.
Note! Maximum life expectancy on the teflon shield is from 1-6 months and for
silicon rubber from 2-6 months, this depends on the speed of operation and
thickness of film.
