etc). Clean or replace as required
CORD AND PLUG

bent or broken. Inspect cord wiring for integrity at termination points by
qualified service personnel. Make sure the cord sheathing extends into
the cabinet interior. If wires are showing on the outside of the cabinet,
remove the unit from use and have repairs made before using the unit.

Vinyl which has been dislodged from the channel due to severe bumping
or scraping can be pried back into place with a common screwdriver.
TENSION SPRINGS

bases/plates and checking to for proper functioning. If bases/plates do not
index properly, and the unit is not overloaded, adjust or replace the
springs. The springs provided with our dispensers are designed to provide
years of use. If replacement springs are needed, they may be ordered
from Carter-Hoffmann. Contact our parts department at 800.323.9793.
