Safety informaon and use

- 5 -

2.2.1 Operang principle

The pellet press is a manually-operated hydraulic press. The device is

ed with a piston pump. This has a sucon and pressure valve, a pres-

sure liming and stop valve. The pressure liming 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 automac venng of the oil

reservoir. It prevents a vacuum being created inside. The locking screw

(9) is protected by a plasc 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 Obligaons of the operator

ang manual. For this reason, it is very important that these persons

actually receive the present operang manual. Ensure that the operang

manual is always near the device.

The Pellet Press may exclusively be used within the scope of applicaons

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
