About the Manual Identifying Information on the Cover
The front cover displays pertinent identifying information for this manual. Most important, are
the published manual number (part number) /ECN (date code). Generally, when a replacement
manual is furnished, it will have the same published manual number, but the latest available ECN.
This provides the user with the latest information applicable to his machine. Similarly all
documents comprising the manual will be the latest available as of the date the manual was
printed, even though older ECN dates for those documents may be listed in the table of
contents.
When communicating with the Milnor factory regarding this manual, please also provide the
other identifying information shown on the cover, including the publishing system, access date,
and whether the document ECN’s are the latest available or exact.

ÈSETTING LIMIT SWITCHES
ÊLimit Switches—Including Microswitches—
Will Be Damaged If Over-actuated!
Any limit switch will be damaged if it bottoms out forcefu lly. This can ben d the rotary shaft or damage
internal components and may cause the switch to stick in one position either permanently or intermittently. Be
aware that an intermittently sticking switch can be mistaken for a malfunctioning microprocessor!

Limit switches must function properly to ensure the safe operation of the machine.
☞ Inspect switches regularly.
☞ Never operate a machine with a malfunctioning limit switch.

ËTravel of Rotary Lever or Plunger
—Set switch and target so that after the switch contacts close (as determined by an ohmmeter), the lever or plunger will then move approxim atel y half of i ts addi ti onal availabl e travel
(see FIGURE 2).
NOTE: It is impossible to determine by feel, sound, or experience at what point the switch contacts make.
The only reliable method is to use an ohmmeter. Switches may also be bench-tested, and the plunger or
rotary shaft scribed to mark this point.

ËFree Position of Rotary Lever

—Attach the rotary lever to the shaft so that, in the free position, the lever
is at a right angle to the direction of relative movement between the switch and target (see FIGURE 3).
RIGHT!

ËAngle of Switch
—Set a plunger switch so that the target and plunger move parallel to each other. It will be
approximately correct when properly installed on its mounting bracket, but may require fine adjustment.
RIGHT!

ÎPlunger Switch Angle
With a roller plunger switch, mak e sure that the roller rotates i n the direction that will accommodate
4
the movement of the target (not at a right angle to the target movement). Also, be sure that a replacement switch
has the roller oriented the same way as the switch it replaces (see FIGURE 5).
RIGHT!
Roller can’t absorb sideways movement
of target (wrong switch used).

ÈPRESS SAFETY FOR INSTALLATION AND SERVICE
ÊGeneral Safety Requirements
(specific warnings, next page and throughout manual)
Incorrect installation, neglected preventive maintenance, abus e, and/or i mproper repairs or changes t o
the machine can cause unsafe operation and personal injuries, such as multiple fractures, amputations, or
death. The owner or his selected representative (owner/user) is responsible for understanding and ensuring
the proper operation and maintenance of the machine. The owner/user must familiarize himself with the
contents of all machine instruction manuals. The owner/user should direct any questions about these instruc-
tions to a Milnor® dealer or the Milnor® Service department. Most regulatory authorities (including OSHA
in the USA) hold the owner/user ultimately responsible for m aintaining a safe working environm ent. There-
fore, the owner/user must do the following:
• recognize all foreseeable safety hazards within his facility and take actions to protect his personnel,
equipment, and facility
• require that personnel are familiar with all functional and safety aspects of the machine
• ensure safety devices installed on the machine are in place and properly maintained
• ensure all machine parts and assemblies are properly maintained.
ËLaundry Facility
sonable safety factor and without undue or objectionable deflect ion--the weight of the fully loaded machi ne
and the forces transmitted by it during operation. (For washer-extractors, see “ABOUT THE FORCES
TRANSMITTED BY MILNOR® WASHER-EXTRACTORS.”) Provide sufficient clearance for machine
movement. Provide any safety guards, fences, restraints, devices, and verbal and/or posted restrictions necessary to prevent personnel, machines, or other moving machinery from accessing the machine or its path.
Provide adequate ventilation to carry away heat and vapors. Ensure service connections to installed machines meet local and national safety standards, especially regarding the electrical disconnect (see the National Electric Code). Prominently post safety information, including signs showing the source of electrical
disconnect.
☞ Safety fence inclosing machine movement areas,
☞ Lockable electric interlocks on all gates, properly interfaced as shown on ma-
chine schematics, to disable machine movement when any gate is opened,
☞ Signs to alert personnel to these hazards, placed prominently around the fenced
area.
—Provide a supporting floor that is strong and rigid enough to support--with a rea-
COLLISION, CRUSHING, AND PINCH HAZARDS—Serious bodily injur y or
death can result to personnel in proximity to machinery/systems that
traverse, elevate, extend, pivot, and/or tilt. The following mandatory minimum safety requirements mu st be ins t al le d wit h t he ma chinery system:
☞ Local codes may require additional precautions.
ËPersonnel
6
Provide personnel with the safety and operating instructions that apply to them. Verify that personnel use
proper safety and operating procedures. Verify that that personnel understand and abide by point-of-hazard
tags on the machine and procedure-specific precautions in the instruction manuals.
—Inform personnel about hazard avoidance and the importance of care and common sense.
ËSafety Devices
facility. Do not allow machine to be used with any missing guard or cover. Service any failing or malfunctioning device before operating the machine.
ËMaintenance
practice and with the preventive maintenance schedule. Replace belts, pulleys, brake shoes/disks, cl utch
plates/tires, rollers, seals, alignment guides, etc. before they are severely worn. Immediately investigate any
evidence of impending failure and make needed repairs (e.g., cylinder, s hell , or frame cracks; drive com ponents such as motors, gear boxes, bearings, etc., whining, grinding, smoking, or becoming abnormally hot;
bending or cracking of cylinder, shell, frame, etc.; leaking seals, hoses, valves, etc.) Do not permit service
or maintenance by unqualified personnel.
—Ensure that no one eliminates or disables any safety device on the machine or in the
—Ensure the machine is inspected and serviced in accordance with the norms of good
ÊDanger From a Descending Press Main Bell
CRUSH HAZARD—Descending main bell will crush anyone under it. Bell
can descend even with power off.
☞ NEVER crawl or reach under the press main bell.
☞ Lock OFF and tag out power and secure factory-supplied safety supports in place
before crawling or reaching under the bell to perform service or maintenance.
☞ ALWAYS ensure all personnel are clear of the press and receiving conveyor be-
fore returning power to either machine for service or maintenance.
ÊDanger From Exposed Electrical Components
SHOCK HAZARD—Contact with high voltage inside electrical boxes or
from other exposed electrical components can kill or seriously injure
you.
☞ Lock OFF and tag out power at wall disconnect before opening any
electrical control boxes.
☞ ALWAYS employ the services of a licensed, qualified electrician when trou-
bleshooting the electrical system.

power is locked OFF and tagged out, and then only for maintenance.
CRUSH HAZARD—Devices in and above the press move without warning
and can entangle, crush, or sever limbs on contact.
☞ NEVER touch or reach into assemblies in or above press fram e unless
and all press side doors are closed and guards are in place before returning
power to either machine.
