INTRODUCTION
This chapter contains the following sections:
1.1 Warranty
1.2 Scope of Manual
1.3 Safety
1.4 Equipment Description
The Edge® and Edge® Blanket automatic spreader/feeders allow operators to feed wet sheets, tumble-
dried blankets, or other large pieces of flatwork into a flatwork ironer or automatic folder. Because
operators do not need to locate and clip one or more corners during loading, each operator can feed
substantially more pieces per hour than using a traditional automatic feeder.
Like the rest of the CHICAGO® product line, the Edge and Edge Blanket are designed, manufactured,
and assembled in Chicago, Illinois. Before the CHICAGO® nameplate is affixed to any machine, a final
inspection is performed, including thorough testing under load conditions.
Any questions concerning the installation, operation, or repair of the unit should be directed to a local
authorized CHICAGO® dealer or the Chicago Dryer Company factory Service Department at:

1.3 Safety
Safe operation and maintenance of the unit
must be the first priority of all supervisors,
operators and maintenance personnel. Safety
begins with safe work habits. In addition, the
unit is equipped with built-in features to promote
safety.
Safe Work Habits
During Daily Operation
Take the flatwork only after it has
cleared the unit. Do not pull on the
flatwork while it is still in the machine.
Post the “Operator Safety” reminders
in a place where everyone will see it.
Read these reminders and follow the
recommendations.
Read and follow all safety labels.
Keep hands and clothing away from
the moving parts of the spreader/feeder
while it is operating.
Always turn off the unit before clearing
a jam.
Operate the spreader/feeder only with all
guards and endframe doors in place and
all safety features operating correctly.
Never operate the unit with any safety
features bypassed.

Maintenance and Repair
WARNING
Always use extreme caution
when performing any repair
procedure that requires the
unit to be operating.
Keep hands and loose
clothing from coming into
contact with any of the
moving parts.
Serious Injury Could Result.
When the unit is running, one
person should be ready at a
STOP button at all times.
Before attempting any repair work, review
these safety steps and precautions to protect
yourself and the unit.
Safety should be the primary concern
of anyone performing corrective
maintenance.
Except where specifically directed, make
sure that the main disconnect switch to
incoming power is OFF.
It is recommended that all maintenance
procedures be handled by at least two
qualified persons. Using the “buddy
system” decreases the risk of an
accident.
Your site should have procedures that
comply with government regulations and
standards for equipment lockout/tagout
during maintenance and repair. Ask your
supervisor for specific information. It
is the users’ responsibility to make sure

Only qualified personnel
should troubleshoot and
repair this unit.
Safety Features
There are six general categories of safety
features:
Main Disconnect Switch
Safety Guards and Sensors
Safety Interlock Switches
Safety STOP Buttons
Safety Labels
Safety Messages in the Manual
Main Disconnect Switch
The main disconnect switch is located on the
outside of the right rear endframe. When turned
to OFF, the main disconnect switch locks out the
incoming electrical power to the unit.
Unless otherwise indicated, turn the main
disconnect switch to OFF before performing any
maintenance or repair work.
For more information on operating the main
disconnect switch, refer to the INSTALLATION
chapter, Installation Procedures section,
Electrical Connection procedure.
Safety Guards and Sensors
Safety guards cover the motor and other
moving parts inside unit. Doors cover the
endframes. These prevent fingers or hands from
coming into contact with moving parts. They also
serve to keep foreign objects from entering the
unit and damaging components.
Mass sensors at the inlet help protect operators
and keep foreign objects out of the unit by causing
the upper inlet arm to raise. Crossbeam sensors
automatically shut down the spreader/feeder
when triggered during machine operation.

Safety Interlock Switches
Safety interlock switches are located behind
each endframe door. Whenever any door is
opened, the interlock on that door is disconnected
and all rotating parts stop moving.
The safety interlock switches are not intended
to lockout the unit. Site management is responsible
for developing and implementing lockout/tagout
procedures that comply with government
standards for use when servicing the unit.
Figure 1-2: Safety labels remind operators and
maintenance personnel that care must
be taken when working near these
areas.
Safety STOP Buttons
There are six red safety STOP buttons arrayed
around the unit, one at each corner and one at
each operator station. Pressing any of these
buttons immediately stops all rotating and
moving parts, releases compressed air pressure,
and shuts down the machine. To reset a pressed
STOP button, twist it.
The preferred method of stopping the operation
of the unit is by pressing the red portion of the
START/STOP button located at each operator
station.
Safety Labels
Orange Warning and yellow Caution labels
(Figure 1-2) are placed at locations around the
unit to keep operators and maintenance personnel
alert in particular areas.
WARNING message labels alert personnel
that personal injury may result from not
following recommended procedures.
CAUTION message labels alert personnel that
the machine may be damaged if conditions,
practices, or procedures are not observed.
When training operators, take the time to
review, understand, and locate all areas where
labels are posted.
NOTE: Do not remove safety
labels at any time. If a label
needs to be replaced, contact
Chicago Dryer Company for free
replacements.

2.1 Site and Utility
Requirements
Figure 2-1 shows the clearances required for
the spreader/feeder. The dimensions noted are the
minimums recommended for efficient production
and service, as well as maintenance access. It is
strongly recommended that enough clear space
be provided around the spreader/feeder to allow
for efficient access.
NOTE: The correct location of
the spreader/feeder is of extreme
importance.
The site must have a level, sturdy floor capable
of supporting the spreader/feeder’s weight without
significant flexing. For weight specifications
and other technical information refer to the
APPENDIX, Technical Specifications.
No special foundation, floor grouting, or
installation of anchors is required. Generally, the
locking floor pads will hold the spreader/feeder
in position and still allow for repositioning when
necessary.
Floor grouting or installation of anchors
may be required to comply with local codes or
conditions, or aboard a ship.
NOTE: The floor must be level
for the optional Easi-Glide to
function properly.
