1. Safety instructions
1.1 Sphere of application
Two versions of the continuous vacuum ller are available:
• HP25E / HP30E in the form of a portioning machine
• HP25E / HP30E in the form of a portioning and linking machine (opti-
onal)
It can also be tted with special attachments (optional).
1.2 Use in accordance with purpose
The HP25E / HP30E continuous vacuum ller is designed and built for
lling, portioning and linking sausages in natural, collagen and cellulose
casings. Standard sausage meats are suitable as the product for lling
to make fresh sausage, salamis and boiled sausage. The ller can also
be used for grinding and separating meat for processing. Other products
may only be processed with the express agreement of VEMAG.
The machine is designed exclusively for industrial use and must not be
operated by persons under 14 years. The respective country-specic
industrial safety regulations must be observed. Apprentices may only
operate the machine under supervision.
The machine is designed for industrial applications.
The machine must not be used in an explosive atmosphere.
Raw materials may be processed at a temperature of between -4 °C and
+ 50 °C.
The vacuum ller requires ambient temperatures between +0.5 °C and
+25 °C.
The vacuum ller is designed for one operator. The operator must have
been trained on site by VEMAG specialists or one of their representa-
tives.
The vacuum ller may only be cleaned by trained cleaning sta󰀨.
The vacuum ller may only be serviced by trained maintenance sta󰀨
(tters or electricians).
The manufacturer’s assembly, commissioning, operating and mainte-
nance instructions must be followed to satisfy the conditions of ”use in
accordance with purpose”.
The HP25E / HP30E continuous vacuum ller is built in accordance with
the state of the art and, in the condition in which it is delivered, complies
with machinery directive 2006/42/EC.
Nevertheless, the machine may present residual hazards if it:
• is not used in accordance with purpose
• is not used in accordance with these operating instructions,
• is used by untrained sta󰀨
• is not carefully cleaned and maintained to specication.

1.4 General safety instructions
• Any person working on or with the machine must have read and un-
derstood these operating instructions, in particular the safety instruc-
tions.
• Store the operating instructions in a safe place for future reference.
• The machine may be used only by trained and authorised sta󰀨.
• Responsibilities during operation must be clearly assigned and obser-
ved.
• The machine may only be serviced by trained sta󰀨 authorized to do
so.
• The machine may only be used if it is in perfect working order. In the
event of changes, such as loss of oil or unusual noises starting, the
machine should be stopped immediately and your in-house mainte-
nance department or VEMAG Customer Service informed.
• The machine may not be operated without the housing cover.
• Route mains cables and data cables (e.g. remote control cable) so as
to avoid tripping hazards.
• Sockets which are not being used must be rmly sealed with the
appropriate protective cap to prevent the penetration of moisture.
Corrosion at the contacts can lead to switching errors.
• It is prohibited to remove, switch o󰀨 or override safety devices. In the
event of damage to safety devices, inform VEMAG Customer Service
immediately.
• Warning signs on the machine may not be removed or painted over.
• Conversions, attachments and other modications to the machine not
approved by VEMAG are not permitted.
• In all cases, generally-applicable and in-house safety and accident
prevention regulations apply in addition to these safety instructions.

1.5 Special safety instructions
Danger!
To prevent injury, switch o󰀨 the machine before any work (assembly, dis-
mantling, cleaning, maintenance, repair). Then switch o󰀨 the main switch
to disconnect the machine from the mains.
Danger!
To prevent injury in the area of the double screws, switch o󰀨 the machi-
ne before undoing the locking nut. Then switch o󰀨 the main switch to
disconnect the machine from the mains. The lling horn holder, grinder
(optional) or linking gear (optional) may only be tted or removed with the
machine switched o󰀨.
Before starting up the machine, always perform the following steps:
• Check that the machine is in proper condition. Leaking oil indicates
leaks which must be eliminated immediately. In this case, inform your
in-house maintenance department or VEMAG Customer Service
immediately.
• Check that the safety devices on the hopper and lling horn holder are
working properly.
Section 5
If you notice any damage, inform VEMAG Customer Service immedi-
ately.
Danger!
To prevent injury, switch o󰀨 the machine before doing any work on the
hopper. Then switch o󰀨 the main switch to disconnect the machine from
the mains. Do not climb onto the machine to check the hopper/hopper
contents, use only the step provided. Under no circumstances use a lad-
der or other aid to get at the hopper of the machine.
Danger!
No-one may stand in the area of the lifting/tipping device (optional). Do
not put any objects in this area.
Only trolleys to DIN 9797 with a capacity of 200 l or 300 l (optional) are
permitted.
200 l: Max. total weight incl. trolley 240 kg
300 l: Max. total weight incl. trolley 350 kg

2.2 Brief description
2.2.1 Hopper
The ller is equipped with a hopper for pouring in product for lling. The
hopper is tted with a safety device which switches o󰀨 the machine when
the hopper is open. A mirror attached to the hopper allows the contents to
be checked.
Danger!
To prevent injury, switch o󰀨 the machine before doing any work on the
hopper. Then switch o󰀨 the main switch to disconnect the machine from
the mains. Do not climb onto the machine to check the hopper/hopper
contents or for cleaning and maintenance purposes, use only the step
provided. Under no circumstances use a ladder or other aid to get at the
hopper of the machine.
The hopper is tted with cushioning as a partial counterweight to prevent
the hopper falling shut under its own weight.
Danger!
Proceed especially carefully when opening and closing the hopper to
prevent injury (risk of crushing). Grasp the hopper only at the ange to tip
it over carefully. Do not open the hopper as long as the lifting and tipping
device (optional) is in its top limit position.

2.2.2 Feed screw
The product is compressed in the hopper by the feed screw (1) and fed to
the thread of the double screws with the aid of the vacuum. Spiral stopper
(2) improves product feed. The scraper (3) attached to the feed screw
completely empties the hopper. The scraper is easy to remove for clea-
ning.

2.2.3 Double screws
The double screws ensure that the product is conveyed gently and evenly
to the outlet. The same volume is conveyed with each rotation of the dou-
ble screws. In this process, the proportion of air in the product for lling is
reduced by the vacuum applied. The double screws feed until completely
empty. The speed of the double screws and thus the quantity of product
portioned can be innitely adjusted.
The product for lling can be portioned either continuously or in individual
portions. If portioning individually, the number of double screw rotations is
a measure of the weight of the individual portion. Individual portions can
be linked in the pauses between individual portions (optional).

2.2.4 Filling horn holder
The machine is tted with a lling horn holder (1) at the outlet as standard
and this is locked at the outlet by the locking nut (2). The lling horn (3)
is attached to the lling horn holder with the aid of the lling horn nut (4).
The product is ejected through the lling horn by the double screws.

2.2.5 Linking gear (optional)
The linking gear (1) is attached to the housing of the machine with the aid
of two bearing journals (2) and swivelled in front of the outlet. It is locked
in position at the outlet with the locking nut (3) like the lling horn holder.
The linking horn (4) is attached to the linking gear with the aid of linking
nut (5).
Danger!
To prevent injury, do not use linking horns with sprung heads. Use only
completely straight, undamaged linking horns and check the selected
linking horn with the relevant test program before production starts.

Behind the cover is main switch (1) which is used to switch the power
supply to the machine on and o󰀨.
Attachments and additional devices (optional) can be connected to the
power supply of the machine via equipment socket (2). Instead of blind
