3 DECAL LOCATIONS 3.1 Safety Decal Locations The types of safety decals and locations on the equipment are shown in the following illustra- tions. Good safety requires that you familiarize yourself with the various safety decals, the type of warning and the area, or particular function related to that area, that requires your SAFETY AWARENESS.

Good operation requires that you famil- iarize yourself with the various operational decals, the type of warning and the ar- ea, or particular function related to that area, that requires your AWARENESS.
4 OPERATION 4.1 To the New Operator or Owner The Renn Mill is designed to receive dry grain from an auger, process it, and deposit it via the discharge auger. Be familiar with the machine before starting. In addition to the design and configuration of equipment, hazard control and accident preven- tion are dependent upon the awareness, concern, and prudence of personnel involved in the op- eration, transportation, maintenance and storage of equipment and in the use and maintenance of facilities.
4 OPERATION Setting up the Roller Mill 4.4.1 Roll Setting Figure 4.1 Figure 4.2 Loosen the wing nuts holding down the top hopper (Figure 4.2) and tip it over center, rotating on the hinge pin until it hits the stoppers. If using flat rolls to roll dry grain, set the rolls a very small distance apart.
4 OPERATION 4.4.2 Roll Gap Adjustment The cam control ( Figure 4.4) serves as a mechanism to make roll gap adjustments accurately and quickly using a 3/4” wrench or socket. The cam positional indicator is set at the factory to the “1”...
4 OPERATION 4.4.3 Feed Gate Control Set the friction knob (Figure 4.6) so that it supports the weight of the feed gate and yet allows the gate to be opened and closed by hand. Note that the setting of the feed gate helps to spread the feeding of grain evenly across the face of the roll.
4 OPERATION 4.4.6 Roll Drive Belt Tension To increase belt tension, loosen the jam nut and turn the tensioning bolt until approximately 15lbs of force at the center of the longest belt span causes a 3/8” deflection. Reset the jam nut to lock the adjustment bolt in place.
4 OPERATION 4.4.9 Transfer Auger Set Up A) Remove the top or bottom lynch pin on the auger rest holding the transfer auger to the mill trailer (Figure 4.12). B) Slide the auger retaining rod off the auger rest (Figure 4.13). Figure 4.12 Figure 4.13 Once the retainer ring is removed, swing the auger out of the auger rest and use the hydrau-...
4 OPERATION Use the hydraulic controls to unfold the transfer auger into the working position. Use the over center latch and safety pin to secure the two sections together. Figure 4.16 Note: When setting up the auger, use the hydraulics in a slow and steady manner, watching for any components that can get caught in between and damaged while swinging into position.
Page 25
4 OPERATION B) When unfolding the auger, check if the locking mechanism (Figure 4.19) or anything else is in the way. C) Upon completion of unfolding the auger, use the catch assembly to clamp the auger in posi- tion (Figure 4.20) Unlocked position Locked position Figure 4.19...
4 OPERATION E) Hold the transport lock up along the discharge auger tube, lining up the holes in the middle of the transport lock with the tabs on the discharge auger tube (Figure 4.23). F) Insert the lock pin and lynch pin to secure the cylinder lock to the auger tube (Figure 4.24). The angle of the discharge auger can now be adjusted using the hydraulics.
4 OPERATION C) Hang the hoses on the hanger. D) Place the lock plate and the pin back on. 4.5 Operating the Roller Mill 1. Make sure to read and understand all of the safety items in Section 2. 2. Ensure that the feed gate is closed (Figure 4.6) before starting the mill. Even a few grains will keep the rolls from turning.
4 OPERATION 4.6 Roller Mill Break-in It is recommended that the mill be run at moderate to full operational speed and at 1/2 to 2/3 capacity during the first hour of operation. This allows the frictional forces to diminish signifi- cantly within the auger tube, and allows the free flow of grain to approach acceptable levels in the system.

5 SERVICE AND MAINTENANCE 5.3 Removal Of Rolls For Servicing 1. With the power disconnected, loosen the jam nuts on each of the spring push bolts and re- lieve all pressure from the spring (see section 4.4.8). 2. Relieve the tension on the roll drive belts and remove. 3.
6 PDI SETUP Your Renn Roller Mill is shipped fully assembled. Take all necessary precautions when moving and operating the equipment. Note: • Practice proper safety procedures when lifting heavy objects. • All hoses should be on the hose hanger when not in use. NOTE: Do not grease the Over Running Clutch when you receive the Mill as they are already greased at the factory.
7 TRANSPORTATION 1. Check with local authorities regarding mill transportation on public roads. Obey all appli- cable laws and regulations. 2. Always travel at a safe speed. Use caution when going around corners or meeting traffic. 3. Make sure an SMV (Slow Moving Vehicle) emblem and all the lights and reflectors that are required by local highway and transportation authorities are in place, are clean and can be seen clearly by all overtaking and oncoming traffic.
8 STORAGE 8.1 Placing in Storage At the end of the operating season, the machine should be thoroughly inspected and prepared for storage. Repair or replace any worn or damaged components to prevent any unnecessary down time at the beginning of the next season. Follow this procedure: 1.
