Step 1 Prepare necessary tools: Drill, impact driver, drill bit PH2, hammer, rubber mallet, metal clippers, ratchet, Allen wrench 5 –...
  • Page 3 Step 3 After removing the boards, take out everything in the box The tandem, gearbox, and body of the machine have to be removed from the box using a forklift The red arrow shows the location where to fixture the parts with the belt Gently place all the items from the box on the floor on either cardboard or bubble wrap so they don’t get damaged.
  • Page 4 Step 4 We start the assembly with the tandem Attach it to the fork lift and hold it slightly above the ground We will attach the wheels next Step 4.1 Before attaching the wheels, assemble them. Use the Long M19 socket on your impact driver. Each tandem has the nuts for assembly on its axle.
  • Page 5 First place one washer on the screw and then screw a nut onto the screw To tighten the nut, use the M32 socket on the impact driver Make sure not to tighten the nut completely. The tandem has to have some room to still move. Tighten it just enough, so that the wheels can still copy the terrain freely To secure the nut use one pin from the bag and...
  • Page 6 After you’re done with that, slide the rubber sleeve over the nut and partly over the bushing of the tandem you just fixtured, to seal it Repeat the same procedure of fixturing the tandem on the other side using the remaining parts from the bag Step 6 Installation of the gearbox in the tandem.
  • Page 7 Step 6.2 After oiling the shaft, the gearbox should slide into place Step 6.3 Secure the gearbox on both sides using the Allen wrench 5 on the 2 screws on the sides. Remove the screws completely and apply thread glue to them.
  • Page 8 Step 7 Now we will attach the gearbox to the body of the machine. To start, you’ll need to lift the body with a forklift and bring it closer to the gearbox Before attaching one to the other, remove the 4 bolts that are attached to the front side of the gearbox, where the drive shaft is coming out The bolts should come out without any problems,...
  • Page 9 Step 7.1 For easier assembly, we will also remove the 2 shafts on both sides on the rear of the body of the machine They are located next to the springs Remove the bendable pin and slide the shaft out of the hole.
  • Page 10 Step 7.3 Take the bolts (together with the washers that were attached to them) and apply some thread lock glue on the thread. First lightly screw all 4 bolts into place. Before we tighten the bolts we have to first check if both ends of the body are leveled.
  • Page 11 Step 8 Now we will attach the drawbar to the body. Prepare the drawbar and place it close to the body of the machine. Step 8.1 Remove the securing pin from the shaft under the cylinder in the front of the machine. Use the 10mm pin punch to extract the shaft from the hole.
  • Page 12 Step 8.2 Right under the shaft you just extracted is a smaller one. Take out the security pin from it and remove this shaft also. Make sure to reinstall the plastic distance rings if they fall out during extraction of the shaft. The plastic ring is marked on the picture with an arrow Step 8.2...
  • Page 13 Lock the cylinder in place using the washer and nut we removed from the drawbar shaft. Use the M36 socket on your impact driver to tighten it Make sure it’s not too tight, so it can still move without friction when adjusting it. Step 8.3 Now we will fit the bushing of the drawbar into the slots we just removed the shafts from...
  • Page 14 Install the shaft back into place Use a hammer to install it but make sure not to damage the greasing nipple in the process On the other side place the washer from the shaft and lock the shaft in place with its security pin Step 8.5 Align the lower bar of the drawbar with the hole (shown with arrows on the picture) where the...
  • Page 15 Step 8.6 Support leg and hydraulics installation Attach the support leg to the drawbar by sliding it over the bushing on the side and securing it with the security pin on the chain For installing the hydraulics, take the hose coming out of the cylinder on the tandem and run it through the hole in the shaft of the gearbox, so that it comes out on top and runs through the...
  • Page 16 Take the hose and run it along the top of the body of the machine. Fixture it in the clamps on the body by unscrewing the bolts holding the top covers and then clamping the hose. After the hose is secured, tighten the bolts back in place.
  • Page 17 Step 8.7 Tensioning the spring between the body of the machine and the drawbar. Attach a belt to one side of the spring. Attach to it the belt with the tensioner. Place one hook through the loop of the belt and the other hook through the hole of the most front part of the drawbar.
  • Page 18 Take off the nuts from the bolts and run the bar through the hole. The bar has holes drilled into its side. Align the holes with the holes you just removed the screws from and put the screws back into place, securing the bar.
  • Page 19 Step 9.1 Installing the barriers Start with the right side barrier. To distinguish between the sides of the barriers look at how they are constructed. The right side barrier has a little square metal sheet welded to it (marked with arrow) When mounting the barrier, that metal square should be facing the rear of the machine Step 9.1...
  • Page 20 For easier installation of the barrier, lock the front part of it with the transport lock. Pull back the pin and fit the hole into the slot as shown in the picture Also, remove the shaft located at the front of the machine (the front U-profiles) so you can mount the barrier.
  • Page 21 Step 9.2 Repeat the same action on the other side of the barrier Finish by inserting the thin washer and locking the shaft with a dowel pin The installation of the left barrier follows the same instructions Remove the shaft under the transport lock Attach the spring and for easier installation, lock the barrier with the transport lock Insert both shafts on the front and back side using a...
  • Page 22 Insert the 4 screws into the holes and screw in the nuts with the washers from the bottom using a M13 wrench and the M13 socket on the impact driver Step 9.4 On the right barrier install the red reflective triangle. Remove the screws from it and install it through the holes on the metal square sheet on the right barrier.
  • Page 23 Step 10 Install the rake arms For the 11-arm rake insert the arms in the following order: 3 bendable arms Followed by 3 rigid arms Then 3 bendable arms And then 2 rigid arms Make sure the rakes face the ground when aligning the mounting holes with the holes on the gearbox arms Take the dowel pins from the bag that was attached to the bar we mounted in step 8.8...
  • Page 24 Step 11 The machine is fully assembled now You should be left with a PTO shaft and a few yellow tarps. The tarps are to be used on the bendable arms when you place the machine in the transport position After installing the PTO shaft in front of the machine, it’s ready to be used The marking on the shaft shows which side of it should...
