Once per week, unless rigorous operating conditions make more frequent lubrication necessary. These conditions include long “dwell” times, extremely dirty or dusty environments, and hot (+80°C) environments. Use commercially available ball bearing grease that is free of molybdenum disulfide (MoS2 -Free). Apply by cleaning the shaft and using a rag to spread the grease thinly and evenly. Using a brush or oil can, apply 90W oil to the reversal mechanism. Be sure to oil the spring coils, insertion points and center ring carrier.
