BASF recommends cleaning coloring equipment thoroughly — once annually at a minimum. While doing so, Sahara® X and Second Harvester® mulch coloring equipment owners should inspect the belly, liners, and weirs of the machine for wear.

- Using a hammer, tap on the top side of the unit to gauge a sound of the thickness of the steel based on the sound pitch.
- Then work your way down the side of the U-shaped belly and listen closely for any changes in pitch. A higher-pitch sound is an indication that the liner is thinning, due to wear.
- Outside in/out movement of the belly is also an indication that the liner is worn.
- You can also measure the liner: Standard liners are 1/4-inch AR400 steel plates — so if the liner measurements are less than 1/16- to 1/8-inch thick, you should consider replacing the liner.
