Safety precautions
1.4. Safety precautions
Safety for customers, machine attendants, and service technicians is paramount in the design and con-
tinuing development of the
ULTRA
. Read this manual carefully, and follow all of the safety rules that it
provides.
Warning!
Never use an extension cord to supply power to the
ULTRA
. The
ULTRA
must be plugged into a proper receptacle. If you do not have the correct
receptacle or if it is damaged, notify store personnel.
Warning!
Never service the electrical components while they are powered on.
Always follow the technical data when servicing the electrical compo-
nents.
Warning!
Mechanical components in the
ULTRA
weigh up to 400 pounds.
Always use lifting devices to remove or replace components.
Warning!
To prevent accidental operation that can cause serious injury, only one
person at a time is permitted to work on or near the
ULTRA
during test-
ing or maintenance.
Warning!
Always remove the keys from the machine when you are done with ser-
vice. If untrained people open the machine, they could be seriously
injured.
Warning!
Do not reach into the In-Feed unit while the machine is in operation. If
you must reach into the machine, open the top door first. Opening a
door activates the safety interlock, which stops all moving parts.
