Maintenance Instructions

[A] CASTERS
Some casters are equipped with Zerk grease fitting so that they may be easily lubricated with a grease gun. Recommended lubrication is at least once every six months.  Lubrication will be required more frequently if carts are cleaned with hot water or a steam cleaning system. Casters with special bearings are recommended for frequent cart wash or steam cleaning situations.

[B] LATCHES
Check frequently to insure that all door latches are secure. Latches may become “sticky” due to residue buildup from daily use and cleaning. Lubricate latches regularly with
D-40, silicone spray, graphite, or other commercial lubricants for stainless steel products. Do not use oil.
