Following are the lubricants recommended for oven maintenance:
1. To lubricate the conveyor chain use: A. Biral BIO30 -synthetic high temperature oil (highly recommended). B. DuBois 2848 -synthetic high temperature oil. C. Tower Oil & Technology Co.-Molyfilm 4AA or 4B Hi-Temp Oils. Note: It is important that a synthetic high temperature oil be used specifically designed to lubricate oven conveyors. The specifications for this oil is unique and automotive synthetics do not comply. Also non-synthetic oils are not to be used as they leave carbon deposits detrimental to the reflow process and chain life.
2. To lubricate the lead screw rail adjusts use: A. Loctite Moly Spray (item number 24378)(highly recommended). B. Biral Antiseize Spray (no number).
3. To lubricate the rail adjust gears and spline shaft drive bearings. A. Alpha Grease & Oil Inc. –H.T.-600 Non-Melt Synthetic Grease (highly recommended). B. Biral -No Melt Grease. Note: The grease is also synthetic, does not bleed off under high temperatures and is specifically designed to be used in an oven atmosphere.
