That section contains important information for getting the best performance and efficien- cy from your machine. 3.5A General The shakerhead assembly contains two sorting decks surfaces called screens. Certain application will require you to change screen sizes for better results.
3. OPERATION 3.5B Loading Procedure S0010 When loading material into the hopper, keep the bucket as low as possible (fig. S0010). Allow the material to slide down the high side of the hopper plate onto the top screen deck. Hopper high Check tailings for size.
3. OPERATION 3.5C Removing Finished Material S0004 After each load is placed into the hop- per, check the finished and tailing piles. Allow adequate area to retrieve finished material from under the hopper and shaker deck area (fig. S0004). For best efficiency, allow at least a full bucket of material to accumulate before retrieving.
3. OPERATION 3.5D Removing Tailings Do not allow the tailing to pile up high- er than the shaker deck area. Remove tailings by pushing the materi- al from the side of the machine (fig. S0007). Do not use the machine as a back stop CAUTION (fig.

3. OPERATION 3.5E Screening Selection / Combinations Proper screen selection S0001 The top plate or screen is used to absorb the impact of heavier material and discharge or separate the larger material to a separate pile. The bottom screen further separates materials and dictates the actual final size of product.
3. OPERATION 3.6 TRANSPORTING Check wheels, tires and axle grease Before transporting the machine, per- form the following checks: Tire pressure 120 PSI (830 kPa). Wheel nuts torque 500 - 550 ft/lbs (680-748 Nm). Check the wheel nut torque and tire pres- sure again after 50 hours.

Keep the screen properly tensioned. See section 4.3A. The screens must be kept tight enough to prevent unwanted movement between the shaker deck and screen material. The screens should be rotated 180º occasionally to allow the wear to be shared evenly on both ends of the screen. For screen selection assistance, contact Thomas Equipment: 1-800-538-0187.
This is if you are using both decks to achieve your end product. The maximum size wire cloth opening you can use with the ProTough 900 would be 7" if using both top and bottom screens.
