[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 a hot
water or 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 WD-40, silicone spray, graphite or other commercial lubricants for
stainless steel products. Do not use oil.
