BUCHI Mixer B-400
Fitting and dismantling the beaker holder
Pull out button ቢ, press the beaker holder up and pull it out.
To fit the beaker holder, slide it into the rail and press down until
button
ቢ clicks into place.
Compulsory inspection and maintenance
All regulations aimed at keeping the Mixer in good working order
must be observed. They include cleaning the Mixer at regular
intervals and examining it for any signs of damage. Each time
the Mixer is repaired, the customer must first make sure that it
only works when the guard door is closed. He must then check
that the cutter is decelerated automatically when the process is
completed, and that the cutter runs in the proper direction (see
Figure 13).
Maintenance of the drive spindle
From 1st Jan. 1996 all B-400 mixers will be supplied with a
CTV spindle nut. The spindle nut enables the drive spindle to be
used without maintenance, so it must not be lubricated.
Replacement of the driving belt for raising / lowering
Remove the rear panel of the apparatus. From outside, insert a
Pozidrive screwdriver (screwdriver for recessed-head screws)
through the holes in the bottom of the apparatus and loosen
both the screws in the drive motor retaining plate. Place the
new belt over the driving pulleys and tension it by means of the
retaining plate. 5mm of slack is allowed for the belt between the
belt pulleys. Then retighten the two retaining plate screws.
