# Six Month Maintenance

- Lubricate conveyor table leadscrews and sprockets. (fig 3) 
    - Clean the leadscrews, chain, and sprockets with a soft wire brush.
    - Apply 1–2 pumps of grease from a grease gun onto the sprockets and leadscrew threads. Adjust the conveyor up or down to spread the grease thoroughly throughout the mechanisms.
    - Avoid adding too much grease, which attracts sawdust
