4.2 Before You Begin Unloading a bag using the Renn Bag Unloader can be a better experience if a number of things are kept in mind before beginning and while operating. The first consideration is something to be taken into account when beginning bagging. Sealing the end of the bag by tying a knot before you begin to fill it can seem like a good idea, but it can cause problems later on in the process.
4.3 Pre-Operational Checklist The efficient and safe operation of the Renn Unloader requires that each operator read and un- derstand the operating procedures and all related safety precautions outlined in this section. A pre-operational checklist is provided for the operator.
4 OPERATION 4.4 Attaching/Unhooking Tractor/Unloader Follow this procedure when attaching the unloader to the tractor: 1. Make sure that all bystanders, especially small children, are clear of the working area. 2. Make sure there is enough room and clearance to safely back up to the machine. 3.
4 OPERATION 4.6 Controls 4.6.1 Hydraulics 1. The flow control valve (A) allows the operator to meter the amount of flow to the cylinders and rewind motor. It is recommended to closely match the hydraulic flow from the tractor to the required flow of the cylinder to maintain adequate ground speed (i.e. the valve should normally operate in the ‘3’...

4 OPERATION 4.7 Break-in (cont’d) COLD WEATHER OPERATION Colder weather will raise the viscosity of hydraulic oil in tractors. The result is thicker oil and an increase in hydraulic pressure. The unloader will perform at its best when the tractor is supplying 4~5 GPM of warm oil.
Page 28
4 OPERATION 4.8 Running The Bag Unloader (Cont.) Lower the power roll hand brake lever to release the brake band from the power roll to allow the power roll to be turned by hand. (Brake shown as fully engaged.) Pull the bottom section of the bag under the sweeps and through the knife under the axle. Hook the bottom half of the bag onto the top set of the power roll teeth.
Page 29
4 OPERATION 4.8 Running The Bag Unloader (Cont.) Turn the power roller by hand and make sure the bag is held tight evenly around the power roll. Below pictures shows how it would look like after first few stokes of the ratchet cylinder, if done properly.
Page 30
4 OPERATION 4.8 Running The Bag Unloader (Cont.) 11) Without engaging the PTO, provide a continuous hydraulic flow to the ratchet system. This system develops pressure as it operates, so a secondary locking device may be required on the tractor control.
Page 31
4 OPERATION 4.8 Running The Bag Unloader (Cont.) 15) With the tractor in neutral and any parking brake disengaged, start the PTO and bring it up to full operational speed. Do not exceed 540 RPM. Do not run the system on idle, espe- cially when breaking in the machine.
4 OPERATION 4.9 Stopping The Unloading Process When the power roll is almost full of plastic, think ahead and be sure to have ample free space in a truck to empty the grain from the discharge auger to clear the machine. Disengage the power drive roll (ratchet) system.
4 OPERATION 4.10 Using The Bag Rewind System When the bagging process has finished, or you have cut the bag at the point at which you would like to begin the rewind process, disengage the brake and cylinder cogs on the ratchet wheel, leaving it free to turn under pressure from the rewind system (section 4.9).
Page 34
4 OPERATION 4.10 Using The Bag Rewind System (Cont.) Start rewinding the plastic without the hand brake pulled on. Make three to four wraps and then use the power roll brake handle to apply friction to control the rewind wrapping tension. The brake friction will need to be reduced as the size of the plastic roll grows.
Page 35
4 OPERATION 4.10 Using The Bag Rewind System (Cont.) 10) Loosen and remove the reel lock retain- ing nut (T-handle). 11) Remove the reel lock bracket. 12) Fold the 4 spokes in towards each other, collapsing the attached reel plates. The plastic roll should slide off of the reel easily.
4 OPERATION 4.11 Hose Hanger A) Open the quick pin that’s holding the lock plate and the front panel of the hose hanger. B) Rotate the Lock plate counter clockwise. If the lock plate is too tight, loosen the bolt at the bottom of the lock plate.
