Issues > Check/Troubleshooting
Motor Breaker trips because of overload
  1. Too many runners in feed hopper
  2. Particles in feed hopper/cutter chamber
  3. Drive Bearings causing burns
  4. Drive Motors not working properly
  5. Drive Motor power cord is disconnected or connections are loose

1. Too many runners (i.e. unused mold parts) in feed hopper
If there are too manu runners, grinding will slow down and trip motor breakers
Always begin work after turning power off!
  1. Remove feed hopper clamps and slowly open hopper to proper side
  2. Remove runners if there are too many

2. Particles in feed hopper/cutter chamber
If there are parts that cannot be broken down (i.e. steel), the blades will not run and may cause the motor breaker to trip
Always begin work after turning power off!
  1. If there are dusts or particles (i.e. metal parts), the cutters will not rotate and trip the motor breakers
  2. Check for dusts or particles. Remove if necessary

3. Drive Bearings causing burns
If the bearings are worn by friction or are damaged, overload will happen during rotation, causing the motor breakers to trip.
Always begin work after turning power off!
  1. Remove feed hopper clamps and slowly open hopper to proper side.
  2. Check condition of bearings and replace if necessary.

5. Drive Motor power cord is disconnected or connections are loose
If power cord is disconnected or its connections are loose, operations will run single-phased, causing the motor breaker to trip.
Always begin work after turning power off!
  1. Check if there are abnormalities on power cord and connections.
  2. If there are any disconnections or loose connections, fix immediately
