People with health problems or under the inuence of medicaon,
drugs, alcohol or exhauson must not operate this device.
The Pellet Press may only be operated by authorised persons and serv-
iced or repaired by trained specialists. All commissioning, maintenance
and repair work may only be carried out by technically qualied per-
sonnel. Qualied personnel are persons who, because of their educaon,
experience and training as well as their knowledge of relevant standards,
regulaons, accident prevenon guidelines and operang condions, are
authorised by those responsible for the safety of the machine to carry
out the required work and are able to recognize and avoid possible haz-
ards as dened for skilled workers in IEC 364.

2.2.1 Operang principle
The pellet press is a manually-operated hydraulic press. The device is
ed with a piston pump. This has a sucon and pressure valve, a pres-
sure liming and stop valve. The pressure liming valve is set for a max-
imum oil pressure of 350 bar, and may not be adjusted. The stop valve
must be closed before the pressing process. The hydraulic oil is kept in an
oil reservoir. This is closed o using a locking screw (9) with an integrated
vent screw. The screw is used for lling and automac venng of the oil
reservoir. It prevents a vacuum being created inside. The locking screw
(9) is protected by a plasc ring. The workspace is surrounded by a Plexi-
glas jacket. There is a door with handle at the front of the jacket. The
pressure cylinder piston (6) is located in the centre of the workspace. It is
protected by a pressure plate. A spindle (4) with hand wheel (3) is used
to create the counterpressure and to clamp the pressing tool. A pressure
gauge (7), which displays the pressure during the pressing process, is
located at the front of the housing.
2.3 Obligaons of the operator
Before using the Pellet Press, this manual is to be carefully read and
understood. The use of the Pellet Press requires technical knowledge;
only commercial use is permied.
The operang personnel must be familiar with the content of the oper-
ang manual. For this reason, it is very important that these persons
actually receive the present operang manual. Ensure that the operang
manual is always near the device.
The Pellet Press may exclusively be used within the scope of applicaons
set down in this manual and within the framework of guidelines put forth
in this manual. In case of non-compliance or improper use, the customer
assumes full liability for the funconal capability of the Pellet Press and
for any damage or injury arising from failure to full this obligaon.
By using the Pellet Press the customer agrees with this and recognizes
that defects, malfuncons or errors cannot be completely excluded. To
prevent risk of damage to persons or property or of other direct or indi-
rect damage, resulng from this or other causes, the customer must
implement sucient and comprehensive safety measures for working
with the Pellet Press.
Neither compliance with this manual nor the condions and methods
used during installaon, operaon, use and maintenance of the Pellet
Press can be monitored by Fritsch GmbH. Improper execuon of the
installaon can result in property damage and thus endanger persons.
Therefore, we assume absolutely no responsibility or liability for loss,
damage or costs that result from errors at installaon, improper opera-
on or improper use or improper maintenance or are in any way con-
nected to these.
The applicable accident prevenon guidelines must be complied with.
Generally applicable legal and other obligatory regulaons regarding
environmental protecon must be observed.
