SAFETY NOTICE

The  warnings  in  this  operator  and  maintenance  manual  are  not  all-
inclusive.  Though  every  effort  has  been  taken  to  ensure  a  detailed
coverage, REMU cannot anticipate every possible circumstance that might
involve a potential hazard. If operation or maintenance is not performed as
specifically  recommended  by  this  manual,  you  must  ensure  that  it  is  safe
for you and others. You must also ensure that the REMU Screening Bucket
will not be damaged or made unsafe by the method you choose.

APPLICATION WARNING

REMU occasionally modifies some REMU Screening Buckets specifically
at the request of the customer to meet the special application needs.

It should be noted that these modifications totally change the performance
and  operation  characteristics  on  the  "Normal  standard  REMU"  unit  and
these characteristics must be fully understood by the user.

Owners and operators are hereby advised that the use of modified REMU
Screening  Buckets  in  applications  for  which  they  were  not  intended  is
strictly prohibited.

If the bucket is operated in conditions for which it was not designed, severe
damage  will  occur  to  the  drive  mechanism.  Damage  caused  by
inappropriate applications will not be supported by REMU’s warranty.

Owners and Operators are hereby warned to check with the distributors or
manufacturers to ensure the particular screening unit will meet the desired
application.
