Introduction
This manual provides important information to familiarize you with safe operating
and maintenance procedures for your SAKAI roller. Even though you may be
familiar with similar equipment you must read and understand this manual before
operating or servicing this unit.
Safety is everyone’s business and it is one of your primary concerns. Knowing the
guidelines presented in this manual will help provide for your safety, for the safety
of those around you and for the proper operation and maintenance of the machine.
Improper operation is dangerous and can result in injury or death.
Sakai Heavy Industries cannot foresee all possible circumstances or varying
conditions to which the operator, serviceman or machine may be exposed to that
might lead to a potential hazard. Therefore, the warnings and cautions listed in
this manual and those placed on the machine are not intended to be all inclusive
and liability for personal injury or damage to equipment or property cannot be
assumed.
All information, specications and illustrations in this publication are based on
the product information available at the time that the publication was written. The
contents may change without prior notice due to modications of the model.
