It sits on a sturdy Sweed stand that moves from area to area on stout caster wheels. Both the stand and hopper are sold separately.

How does it work ?
-
-
- Start the machine and give it some time to get to the working RPM. (mostly 15 sec)
- Grab the material you want to chop and give it to the infeed opening on the machine.
- For your own safety, stand to the side.
- The machine will pull and chop the material you have entered until it ends.
After chopping, the nuggets will fall out underneath the chopper in the collecting bin of your choice.
Health and safety
An emergency stop will shut off the machine after you pressed it.
This model has limited pulling forace so you could not get hurt or injured.
The level of noise production is very hard to determine because it depends a lot on the conditions of use. If you work steel or pet, it's different than when you chop material that has a resonance. The type of collecting bin is important. If the chopped material falls into a cardboard box it will not make as much noise as when it falls into steel container but when the latter becomes filled up with material its noise level will go down.
No specific dust emission could be determined but it needs to be said that - depending on the material you chop - it could produce dust.
Maintenance
This chopper uses knives (blades) which can be turned over 4 times before replacement becomes necessary .
To rotate or change a knife, the manual shows it to you step by step with the help off full color pictures .
It's not easy for us to know how long a knife can last because again every customer is different . In a general way we can say that the majority of our customers rolls the knives over once / year . Customers running big piles of rusty straps or customers who cut very thin material will have to change their knives faster than customer who have no dust and working brittle material .
Regular greasing and cleaning is a must .
Environment
option # 1 : a customer working steel straps :
You will no longer drive around with trucks to carry more air than material
option # 2 : a customer who work PET - straps:
Making new material for straps from recycled material saves up to 75% off the Co2 cost for energy . With every kilogram of PET brought back to make new, it saves 4.3 kg CO2 which is equal to driving a car for 40 km .
