6. MaintenanceFor normal operation, annually re-lubricate both motor bearings with approximately ten (10) drops of5W-30 oil. The gears of the gearbox assembly are lubricated with a special high temperature, food gradelubricant (SPD-2109) at the time of manufacturing. The level of grease in the gearbox should be checkedannually and will not normally require further lubrication unless seal breakage occurs. After the grease hassettled to the bottom of the gearbox, the grease level can be checked. The grease level should not be morethan 1/4" below the vent plug. (See Figure 6A.) It may be necessary to insert a wire through vent plug holeto determine the grease level. The grease level also can be checked by removing motor and viewinggrease level through the hole for the motor pinion gear.Inspect seals annually for signs of leakage (check bearings annually for tightness).In the event the motor fails to start, check power supply to the motor. If power supply exists and motor stillfails to start, disconnect power and check blade for freedom of rotation. If power does not exist, check forblown fuse or flipped circuit breaker.If motor stops operating for no apparent reason, wait approximately 5 minutes for the automatic overloadprotection device to reset and reattempt operation. If problem continues, check power supply for voltageand check blade of unit for freedom of rotation.If motor pinion requires removal for any reason, it must be properly installed and located, as shown in theparts assembly on Page 18.Figure 6A The gear box assembly showing grease level.WARNINGDisconnect power supply before attempting any type of service. The motor isprotected with a self-resetting overload protection.DANGERFailure to disconnect power can result in serious injury or death.16 PNEG-258 Scattergrain Grain Spreader
7. Troubleshooting GuideCorrect Spreading PatternGrain is slightly depressed in thecenter. Grain flow is centered andthe spreader is level.Trouble Probable Cause IllustrationLarge doughnut shaped ring caused bygrain hitting high on bin wall.Tilt blade downward, decrease bite.Remove blade extension.Spreader blade too flatGrain is high in center of bin, smalldough nut.Flatten blade, increase bite, decrease grainflow to spreader. Add blade extension.Spreader blade too steepGrain is high on one side of bin.Level spreader, correct grain flow tospreader, (never allow grain to flow intospreader at an angle or off center).Not level, not centeredPNEG-258 Scattergrain Grain Spreader 17
