Operating Guidelines 

Air Chicago (Standard/XW/XL/XXL)

3-14

Number of Operators

Generally,  only  one  operator  is  needed  to 

operate the Air Chicago. Its design and operation 

allows one operator to efficiently feed towels and 

other items and to retrieve folded pieces from the 

return conveyor for proper storage. This labor-

saving feature means other operators are free for 

other work.

Post the Standards

When  the  correct  standards  have  been 

established for each item, post them. Make up a 

chart that shows each item with:

The name or measurements that are 

commonly used to describe the item.
SIZE SELECT button to press.
Note if this item requires that one of 

the CHI panels functions be changed 

manually.
Whether to feed this item in the middle 

of the unit or centered on the edge of a 

primary fold ski.

By following posted standards, all operators 

will  use  the  best  techniques  for  maximum 

productivity.


Work Habits

Once  the  supervisor  has  established  the 

proper standards for using the Air Chicago, it is 

necessary to implement them. Maximum safety 

and productivity happens when operators:

Think safety first

Sort items into the established categories

Follow the standards for each category

Use good feeding technique at all times

Safety

The first priority of everyone in the laundry 

must be safety. The air permeable barrier and all 

safety guards and covers must be in place when 

the machine is operating. No one should ever put 

a hand into the machine while the power is on.

Sort Into Categories

The Air Chicago works best when one size 

is done at a time. Follow the posted standards 

and  sort  the  goods  into  the  size  categories 

established.

Standards for Each Category

The supervisor will post standards for each 

item to be processed.
