1
Remove the material from the TrueBlend SB-4 extruder hopper.
2
Disconnect the load cell wiring that extends into the control box (see wiring dia-
gram).
3
Remove the two screws that are used to mount the TrueBlend SB-4 extruder
hopper to the load cell.
4
Remove the TrueBlend SB-4 extruder hopper.
5
Remove the two screws that are used to mount the load cell to the hopper
frame.
6
Place a small amount of removable strength Loc-tite™ onto the two screws and
re-install the load cell and TrueBlend SB-4 extruder hopper back onto the hop-
per frame. Make sure that the load cell and hopper are mounted square with the
hopper opening exit and tighten the screws to a value of 10 Nm.
Do NOT use excessive force. Forces that are exerted on the load cell from outside when
attaching and removing the TrueBlend SB-4 extruder hopper load cell may damage the
very sensitive load cell.
✐
NOTE: A set screw positioned below the load cell is used as a stop for the load cell to prevent
damage if over weighting occurs. If this bolt was not loosened during removal or installation, it
should not need adjusted. If it was loosened, the gap needs to be reset so the load cell contacts
the bolt when the weigh bin is loaded full with material. A .020" feeler gage could be used to set
the gap.

High voltages can cause life-threatening currents in the body and injury from elec-
tric shock. Allow only trained and qualified electrical technicians to work on the
electrical system. Before any electrical work, disconnect the unit from the power
supply and lock-out to prevent unauthorized persons switching it on.
