B. Grease Lubrication <br />The greatest cause of bearing failure is over greasing rather than under greasing. <br />For this reason, HSI does not recommend use of permanently installed grease <br />fittings as they invite overgreasing. <br />A special high speed grease is required in grease -lubricated machines. Use of any <br />other type of grease without explicit approval of HSI Service Department will <br />automatically VOID THE MACHINERY WARRANTY. <br />GREASE SPECIFICATIONS <br />NGLI GRADE ...................................................

If a months or more have elapsed since <br />shipment from the factory, remove bearing housing covers and inspect for moisture due <br />to condensation. <br />,W To add grease during operation: <br />i. Remove plugs from top and bottom of bearing housing <br />(see diagram on page 30) <br />ii. Bring blower/exhauster up to a stabilized operating temperature. <br />iii. Add grease through the top opening in the specified amount <br />(see diagram on page 30) <br />iv. Reinsert plug in top opening <br />V After thirty minutes wipe off expelled grease and reinstall bottom plug. <br />22 <br />Indian River Landfill O&M Proposal Page 11 www.scsengineers.com <br />
