Replacing The Frame With A Mesh; Maintenance - Metra Electronics SGC Operating Manual

10. REPLACING THE FRAME WITH A MESH

Replacing the frame with a mesh is as follows:
• Disconnect SGC from the electricity network;
• Carry out cleaning of SGC;
• Disassemble SGC from the grain cleaner;
• Put SGC on the side where the electric motor is located;
• Unscrew the fastening from below that connects the frame with the mesh with the
crank mechanism (Picture 1);
• Disconnect the carabiner connections located on the edges of the frame with the
mesh (Picture 2);
• Unscrew the fasteners connecting the frame with the mesh to the rubber damper
cloth (Picture 3);
• Dismantle the frame with the calibration mesh by pulling it out from under the rubber
sheet;
• Install a mesh with a frame of the required caliber;
• Check the correct installation of the frame with the mesh and the reliability of fastening
the mechanisms;
• Switch on SGC without feeding grain. Make sure that the movement of the frame with
the mesh occurs smoothly without obstacles.

11. MAINTENANCE

SGC CLEANING:
During operation, it is necessary to clean the SGC, monitor the condition of the calibration
mesh, preventing its excessive sagging, check and timely replace lubricating materials,
monitor the condition of the frame with the mesh, crank mechanism and bearings.
ATTENTION! All cleaning works must be performed only after SGC is switched
off from the electricity network!
SGC cleaning should be carried out regularly, depending on its clogging, but not less
often than once every three working days.
• Disconnect the SGC from the electricity network.
• Remove dust and dirt from the body of the unit.
• Remove all remaining material from the mesh.
• Make sure that the movement of the frame with the mesh is smooth and without
obstacles.
• Before sending the SGC for storage or preservation, it is necessary to clean the SGC,
check the reliability of the fastening of the moving parts and mechanisms of the SGC,
and, if necessary, tighten the fasteners.
• After SGC storage or preservation, it is necessary to remove dust and mud deposits
with a soft cloth, check the smoothness of the calibration frame with a mesh, and, if
necessary, perform maintenance on the electric motor.
