ÈABOUT THIS MANUAL

ËScope—This instruction manual is intended to provide preventive maintenance, service procedures, an d

mechanical parts identification for your machine. See the safety manual for safety instructions before installing,
servicing, or operating this machine. See the installation guide for facility requirements, installation instructions,
and assembly instructions. See the operator guide for operator instructions. See the reference manual for program­ming, operating, and troubleshooting instructions. See the schematic manual for electrical parts identification and
electrical troubleshooting.

ËManual Number/Date Code (When To Discard or Save)—The manual number/date code is lo-

cated on the inside front cover, upper right corner just above the manual name. Whenever the manual is reprinted
with new information, part of this number changes. If the date code after the “/” changes, the new version applies

to all machines covered by the old version, but is improved— thus the old version can be discarded. If the

manual number before the “/” changes, the new manual covers only new machines. Example: Discard MAT-
MODELAE/8739CV when MATMODELAE/8739DV is received (minor improvements). Also, discard MAT­MODELAE/8739DV when MATMODELAE/8746AV is received (major improvements). But keep
MATMODELAE/8746FV when MATMODELBE/8815AV is received, since the new manual no longer applies to
machines originally shipped with the old manual.

ËDocuments and Change Bars —The individual documents comprising this manual use the same revision

criteria as the manual. Text documents also display change bars. Example: When section MSOP0599AE/9135BV
becomes MSOP0599AE/9135CV, change bars with the letter “C” appear next to all changes for this revision. For
a major rewrite (e.g., MSOP0599AE/9226AV), all change bars are deleted.

ÈINSTALLATION AND SERVICE SAFETY FOR SUSPENDED

WASHER-EXTRACTORS AND CENTRIFUGAL EXTRACTORS

ÊGeneral Safety Requirements

(specific warnings, next page and throughout manual)

Incorrect installation, neglected preventive maintenance, abuse, and/or improper repairs or changes to 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 responsibl e 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 instructions to a Milnor® dealer or the Mil­nor® Service department.

Most regulatory authorities (including OSHA in the USA) hold the owner/user ultimately responsible for
maintaining a safe working environment. Therefore, 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

—Provide a supporting floor that is strong and rigid enough to support--with a reasonable

safety factor and without undue or objectionable deflection--the weight of the fully loaded machine 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 C ode). Prominently pos t safety inform ation, including
signs showing the source of electrical disconnect.

ËPersonnel

—Inform personnel about hazard avoidance and the importance of care and common sense. Provide
personnel with the safety and operating instructions that apply to them. Verify that pers onnel use proper safety and
operating procedures. Verify that personnel understand and abide by point-of-hazard tags on the machine and pro­cedure-specific precautions in the instruction manuals.

ËSafety Devices

—Ensure that no one eliminates or disables any safet y device on the machine or in this facil ity.
Do not allow machine to be used with any missing guard or cover. Service any failing or malfunctioning device
before operating the machine.

ËMaintenance

—Ensure the machine is inspected and serviced in accordance with the norms of good practice and
with the preventive maintenance schedule. Replace belts, pulleys, brake shoes/disks, clutch 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, shell, or frame cracks; drive components 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.

Service and Maintenance

MSSM0201CE/9 84 0A V (1of 11 )

ÈLUBRICATION AND PREVENTIVE MAINTENANCE

FOR HYDRO-CUSHION

®

MACHINES

ÊGeneral Requirements

Maintenance procedures require:

• A hand operated grease gun.

• The correct lubricants (see “LUBRICANTS FOR MILNOR MACHINES,” in the Table of Contents).

ÊLubricant Requirements

To achieve the optimum performance and service life from th e Milnor® machine and as a warranty require-

ment, the machine must be lubricated in strict accordance with the instructions in this section.

ENTANGLE AND CRUSH HAZARD—Belts and pulleys can entangle and crush
body parts.

☞ Lock OFF and tag out power at the wall disconnect before servicing, except

where specifically instructed otherwise in this section.

☞ Insure belt and pulley guards are in place during service procedures.
☞ Permit only qualified maintenance personnel to perform these procedures.

CRUSH/SEVER HAZARD—Tilting mechanism can crush or sever parts of your
body caught in them.

☞ Install the safety stands before performing maintenance under a tilted ma-

chine.

☞ NEVER test or operate (manually or automatically) any machine function

with any portion of a person’s body under the tilted machine—even if the
safety stands are inst al le d.

CRUSH/SEVER HAZARD—Tilting machines with tilt wheels/cradles may lunge
forward or rearward and even fall over if the tilt wheels at the non-tilted end are
raised out of their cradles—killing/injuring personnel and/or damaging prop­erty.

☞ NEVER manually tilt (lift) both ends of the machine at the same time. One end must

always be seated in it s cradle.

☞ ALWAYS visually inspect the tilt wheels to be sure they are all fully seated in their cra-

dles before each manual tilt up.

☞ Hydraulic valve manual operation must be done by trained competent maintenance per-

sonnel who thoroughly understand the system and all the consequences of manual
operations.

☞ ALWAYS understand beforehand all the consequences of manually operating hydraulic

valves.

☞ Never permit operation with malfunctioning tilt limit switches.

ÊCorrect Grease Gun Procedures

1. Do not use a pneumatic grease gun. Pump grease slowly, taking 10-15 seconds to complete each stroke.

A grease gun can build up extremely high pressure which will force seals out of position and cause them to
leak, even though both the seal and the bearing housing are equipped with spring loaded relief plugs.

2. Apply quantity of grease called for in the checklist. Over-lubrication can be as damaging as under-lubrica-

tion. Where quantities are stated in strokes, one stroke of the grease gun is assumed to provide .0624 fluid
ounces (1.77 grams) (by volume) of grease. Therefore, one fluid ounce (28.3 grams) of grease would be pro­vided by 16 strokes of the grease gun. Determine the flow rate of your grease gun by pumping one ounce
into a calibrated container. If fewer than 16 strokes are required, all quantities in strokes in the chart should
be reduced accordingly, and if more than 16 strokes are required, the number of strokes should be increased.
Before starting lubrication, make sure your grease gun is working and that you get a full charge of

grease with every stroke.

3. Do not pump grease in until it oozes out of the spring loaded relief plugs. Plugs bleed out excess grease

and help prevent abnormal pressures from building up in the housing during operation (especially when the
machine is first commissioned and after each lubrication). Plugs will not protect against over-lubrication.

4. Do not over-lubricate motors. Over-lubrication of a motor can seriously damage it by forcing grease into

motor windings. Over-lubrication of the extract motor can force grease into the centrifugal switch causing it
to malfunction.

5. Do not allow grease to drip on the brake disk or clutch tire/drum during lubrication. This will reduce

the braking action considerably, and may permit the cylinder to creep while loading and unloading.

NOTE 3: All v-belts are not alike. “Super” or “High Capacity” v-belts frequently have

considerably higher capacities than “Standard” belts. Sometimes, one brand of

v-belt is more suitable than another brand of v-belt, although both v-belts are

“interchangeable”. It is always best to purchase replacement belts from the

original manufacturer of the equipment. Purchasing exact replacements of the

original belts is the best way to assure belt life equal to the original set.

Occasionally, Milnor

®

will change a belt specification to improve belt life.

Belts purchased from Milnor

®

are as currently specified.

NOTE 4: Once a month or once every 200 operating hours, whichever occurs first.

NOTE 5: Main bearings and jackshaft bearings (if so equipped) are prepacked with

lubricant at the factory. Do not add grease for thirty days. During the first

month’s operation, some grease will ooze out of the automatic grease fittings

at the bottom of the housing(s). This is normal. These grease fittings allow

excess grease to escape, thus avoiding over-heating. This escaping lubricant

need not be replaced. Every time these bearings are lubricated, the surplus

grease will come out of the spring loaded relief fittings after a few hours

running time.

NOTE 6: Bearings can run hot enough to make it extremely uncomfortable for a

person to hold his hand on the bearing housing for more than a few seconds.

This is normal.
