Disconnect main power supply before performing maintenance.

Lockout/tagout the spiral according to your company’s lockout/tagout before performing maintenance.


NEVER expose plastic belts and chains to a potential source of ignition. Flames resulting from burning plastics may emit toxic smoke and gasses as well as cause serious injuries and property damage.

Fire detection, fire alarm and fire suppression systems are STRONGLY RECOMMENDED in areas around ovens or other high temperature processes where conveyed products may be burning or hot enough to ignite plastic belts and chains.

ALWAYS comply with National Fire Protection Association (NFPA) standards as well as building codes and ordinances regarding fire protection.

SPECIAL CARE MUST BE TAKEN when maintenance or other processes require WELDING OR SIMILAR “HOT WORK” near conveyors with plastic belts and chains. ALWAYS train welders and use observers with fire extinguishers as required by the Occupational Safety & Health Administration (OSHA) and other safety regulations and policies. Cover and protect all exposed plastic components from flames, sparks and heat

Lubricate Recommedation


G&F Systems recommends only applying 100% pure food grade silicone which can be purchased directly from G&F Systems.



Spiral belt lubrication should be done periodically to maintain and help eliminate wear on the spiral belt. A lubrication schedule should be devised to suit your application and maintenance schedule.

Automatic Spiral Belt Lubrication:

  1. Each spiral conveyor system comes with an Automatic Spiral Belt Lubrication system which consists of a fill canister, solenoid valve and dispersion applicator.

  2. The Automatic Spiral Belt Lubrication system is mounted on the return belt path. Always inspect the location of the return tracks and ensure the applicator is aligned with the tracks.

  3. For conventional low tension spiral systems, ONLY apply belt lubrication to the outside and middle track. NEVER lubricate the inside track as this can reduce the frictional relationship needed between the belt and spiral cage potentially increasing system tension.

  4. For Direct Drive Belt Spiral Systems, all tracks can be lubricated as this belt system does not rely on a frictional relationship between the belt and spiral cage to drive the belt.

Manual Spiral Belt Lubrication:

  1. At times the spiral belt will need to be lubricated manually. This manual application may occur after system cleaning or system maintenance.

  2. The recommended method to apply belt lubrication manually is via rags. Tie rags to the underside of the belt (above each track – NOTE – outside and middle tracks only for conventional spiral systems).

  3. Prior to applying the rags to the underside the belt, saturate each rag in food grade silicone.

  4. Turn spiral system on. Rags will be carried over the UHMW track wearstrip dispersing food grade silicone directly to the track wearstrip as the rags travel.

  5. STOP THE SYSTEM PRIOR TO THE RAGE ENTERING INTO THE TAKEUP TOWER. The rags cannot engage the belt drive shaft sprockets.

  6. Personnel will need to remove rags from belt manually at this point.

Inspection and maintenance intervals

Time interval What to do?  
  • Daily
  • Check lubrication canister silicone level.
  • If silicone level is too low an indicator alert will appear on HMI screen.
  • Weekly
  • Check lubrication flow hoses for blockage.
  • Check for water inside lubrication canister.
  • Monthly
  • Check inventory for silicone quantity.
  • If inventory is low, purchase 5 gallons from G&F
  • Depending on the operating conditions
  • Begin frequency rate of automatic spiral belt lubrication at 1 drop per minute.
  • Adjust this rate as required. Adjustment is made manually via a needle pin valve at the canister
