3. General & Preventive Maintenance

1.Maintenance Cautionary Notes

1.1 Important Precautions.

READ this manual before operating or servicing this equipment.

  • ALWAYS remove power and wait at least 30 seconds before connecting / disconnecting any internal harnesses. Failure to observe these precautions may result in damage to, or destruction of the equipment.

  • ALWAYS take proper precautions when handling static sensitive devices.

  • SAVE this manual for future reference.

  • DO NOT allow untrained personnel to operate, clean, inspect, maintain, service or tamper with this equipment. 

  • DO NOT connect or disconnect any digital or analogue components to the equipment with power connected or damage may result.

  • Do not use any chemicals to clean this equipment, unless otherwise stated in this manual.

  • When using compressed air to blow down this equipment, do not direct the air stream at electrical/pneumatics or other sensitive devices.  Ensure correct PPE is used appropriately.

  • Do not wet wash any of the equipment unless stated to do so.

  • Report all defects immediately to your supervisor or manager.

  • When first installed all surfaces must be cleaned of all foreign material.

 

Ensure all energy sources are isolated before attempting to clean this machinery. All loose products should be gently brushed off the machine components with a small hand brush. If a vacuum system is installed for cleaning purposes use a small application head to remove loose product from this equipment. 

 Where applicable, follow the manufactures instructions stated in the original equipment manual. All safety warnings and cautionary advice must be observed. 

 Cleaning should occur at the end of each day’s production or before maintenance work.  Cleaning of every station and work area on the process and line equipment is very important.

 Clean with a dry lint free cloth or soft brush; use a vacuum attachment if installed. 

 Include cleaning for these areas: 

  • All access points including guards.

  • All the floor area underneath and around the machine.

  • Sensors and switches.

  • Motors and gearbox units.

  • Pneumatic cylinders and fittings.

  • Internal and external surfaces and the dust extraction ducting including flexible tubing.

  • All product contact surfaces must be cleaned to an acceptable hygiene level.

 

If the product has been exposed to moisture and solidified a scraper with a hard plastic blade can be used. Under no circumstances is a metal blade scraper to be used. Once the hardened product has been removed the scraper and the cleaned area must be wiped down. Any wet areas after washing must be cleaned using a clean dry cloth. Wipe all areas afterwards using a clean dry cloth.

1.2 Personnel.

  • Only qualified personnel are permitted to operate, adjust, service or maintain `BRML' equipment.

  • Personnel are prohibited from interfering with machinery in any way when it is in operation.

 

1.3 Safety.

 

            WARNING

     

 Safety screens and covers must be maintained where fitted and replaced in the correct position after maintenance or servicing is completed.

1.4 Service, Repair & Adjustments.

 

  • Before servicing or repairing, stop the machine and disconnect all energy sources.

  • Maintenance and adjustments must be performed with all energy sources isolated unless otherwise specified in this manual.   

  • To isolate the machinery, refer to the “warning” page in this manual.

 

1.5. Pneumatic Supply.

  • High pressure pneumatic systems are dangerous.

  • Do not service or troubleshoot systems with the compressed air supply on.  Be sure to bleed off any trapped compressed air before working on components since it is possible to have high pressures trapped in the pneumatic or gas lines.
