DANGER
SECTION 1—IN GENERAL
Safety Precautions
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury .
This safety alert symbol identifies important safety messages in this
manual. When you see this symbol, be alert to the possibility of personal
injury, and carefully read the message that follows.
CAUTION used without the safety alert symbol indicates a potentially haz-
ardous situation which, if not avoided, may result in property damage.
CAUTION
Efficient and safe machine operation depends on the development, implementation and enforcement of a safety pro-
gram. This program requires, among other things, the proper selection of point-of-operation guards and safety devices
for each particular job or operation and a thorough safety training program for all machine personnel. This program
should include instruction on the proper operation of the machine, instruction on the point-of-operation guards and
safety devices on the machine, and a regularly scheduled inspection and maintenance program.
Rules and procedures covering each aspect of your safety program should be developed and published both in an
operator’s safety manual, as well as in prominent places throughout the plant and on each machine. Some rules or
instructions which must be conveyed to your personnel and incorporated in to your program include:
DANGER
Never place your hands or any part of your body in this machine.
Never operate this machine without proper eye, face and body protection.
Never operate this machine unless you are fully trained and instructed and unless you have
read the instruction manual.
Never operate this machine if it is not working properly—stop operating it and advise your supervisor
immediately.
Never use a foot switch to operate this machine unless a point-of-operation guard or device is provided
and properly maintained.
Never operate this machine unless two-hand trip, two-hand control or presence-sensing device is installed
at the proper safety distance. Consult your supervisor if you have any questions regarding the proper safety
distance.
Never tamper with, rewire or bypass any control or component on this machine.
A company’s safety program must involve everyone in the company, from top management to operators, since only as
a group can any operational problems be identified and resolved. It is everyone’s responsibility to implement and com-
municate the information and material contained in catalogs and instruction manuals to all persons involved in machine
operation. If a language barrier or insufficient education would prevent a person from reading and understanding various
literature available, it should be translated, read or interpreted to the person, with assurance that it is understood.
FOR MAINTENANCE AND INSPECTION ALWAYS REFER TO THE OEM’S (ORIGINAL EQUIPMENT
MANUFACTURER’S) MAINTENANCE MANUAL OR OWNER’S MANUAL . If you do not have an owner’s
manual, please contact the original equipment manufacturer.
