Can the bale be ejected even if the ready bale-lamp does not indicate?
Yes – by opening the feed door/main door when the press ram is in lower position,
the press cycle can be interrupted and bale ejection be done.
It should only be done exceptional, and with extra caution.
This presumes that there is compacted material in the press chamber.
What is fuse of time delay type?
On ceramis fuses there is usually a snail, which means that the fuse is of time delay type.
At fuse problems, check that all three fuses are OK. For balers we always recommend fuses of time delay type, or MCB (miniature Circuit Breaker) class D, for uninterrupted operation.
Must the cartons be torn apart before compaction?
No, this should be avioded. The resultat might be a worse bale.
To tear the cartons is common when using a multi chamber press, where the feed volume is reduced.
This ”bad habit” could be hard to get rid of when changing into a front-loaded NP baler.
How many bales correspond to 10 m3 cardboard?
Ten (10) m3 means about 150-200 kg cardboard. How many bales this equals is of course depending on the size of baler but using an NP80 this means one bale.

Why is the bale weight increased when the press ram is stopped in lower position?
This applies especially at compaction of plastics, when more air is squeezed out of the material.
By means of the screw drive in our NP balers the material can be hold under pressure without using electricity!
We call this function ”Stay ´n Hold” and it can be programmed on all our newer balers, giving heavier bales.
How shall the cartons be placed inside the baler?
Put the boxes with bottom up and distribute them in the press chamber.
