PREVENTIVE MAINTENANCE PROCEDURES

Procedure 1: Lubricate Transport Conveyor Chain

(Interval - 2 weeks)

NOTE: This procedure is automatic on Ovens equipped with the Computer Controlled Chain Lube option

On systems equipped with the Edge/Rail conveyor system, check the conveyor transport chain for lubrication.

The chain should be lubricated if it looks dry or the chain links do not move freely over the sprockets, Use

“Darmex” 773ND lubricant or equivalent. Remove the chain guards at the offload end of the system; apply the

lubricant with a small brush at the opening of the chain plates. Avoid getting lubricant on the product transport

pins. Apply the lubricant sparingly, do not soak the chain or apply it such quantities where the lubricant drips off.

Make sure the factory exhaust system is on and operating properly, as you may notice some fumes when the

heaters are turned on.
