Step 1

First, start by taking the two base bars and connect them together using the laser-cut powder-coated triangular plates. Connect these using the 4x M10 60mm Button Head Bolts. Make sure to place an M10 washer on either side of the assembly to prevent scratching of the paint and bolt together using 4x M10 Locking Nuts

Step 2

Next connect the 2 timber footplates adding the shorter 8x M10 30mm Button Bolts, adding an M10 Nut to each. Then add the optional drip plate using the 4x ½” screws provided. These holes may need to be piloted to prevent the splitting of the wood. Be Careful not to overtighten these bolts.

Step 3

Next take the large 30 x 60mm beam and connect the two 90deg base plates as shown in the diagram below. This time use 5x M10 60mm Standard Bolts with washers either side and M10 locking nuts like in the previous steps. The tighter the better for these bolts.

Step 4

You may want to take this opportunity to attach the anti scratch feed on the bottom of the machine.

Step 5

Next using the 2x laser cut plates with angles, sandwiching the barrel in between the two plates using the 5x M10 bolts. Make sure to do this process slowly, not trapping any cables or connections. It may be quite hard to alight the barrel protector with the lower slot highlighted in red.

Step 6

Next install the hopper, although, in this diagram the bolts are inserted from the inside out, it is actually easier to insert the bolts from the outside, adding the nut on the inside. Use the M5 16mm bolt to attach this. It will be tight, however, this is required to ensure a secure fit. If you find that a secure seal is not obtained at the bottom of the hopper against the barrel. Use the heat-resistant tape (supplied) near/around the barrel opening, to prevent any plastic from falling from the hopper. The gap is deliberated to prevent heat from creeping and melting plastic inside the hopper.

Step 7

Next add the two pull rods, lever and plunger using the remaining M10 bolts. Make sure to place a washer between the pull rods and the lever and the pull rods and the vertical bar. To ensure smooth motion.

Step 8

Finally add the electronics box, using the 3 M5 bolts.

Step 9

Finally, plug the two quick connection plugs into their respective colour-coded sockets on the electronics box. These should be pressed in and twisted to lock into place. Then connect the matching (IMPORTANT: DO NOT MIX THESE UP) thermocouple connectors for the barrel to the electronics box. You may have 3 yellows or 1 depending on your model.

Step 10

Now attach the power supply and you are ready to get started. Using the switch on the back of the electronics box to turn on and off the machine. 

Happy melting :)
