2.3 SAFETY TRAINING
1. Safety is a primary concern in the design and man-
ufacture of our products. Unfortunately, our efforts
to provide safe equipment can be wiped out by a
single careless act of an operator or bystander.
2. In addition to the design and conguration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, con-
cern, prudence and proper training of personnel
involved in the operation, transport, maintenance
and storage of this equipment.
3. It has been said, "The best
safety feature is an informed,
careful operator." We ask you
to be that kind of an operator.
It is the operator's responsibility
to read and understand ALL Safety and Operating
instructions in the manual and to follow these.
Most accidents can be avoided.
4. Working with unfamiliar equipment can lead
to careless injuries. Read this manual, and the
manual for your auxiliary equipment, before
assembly or operating, to acquaint yourself
with the machines. If this machine is used by
any person other than yourself. It is the ma-
chine owner's responsibility to make certain
that the operator, prior to operating:
