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 responsible for underst anding 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

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 safet y standards, especially regarding the electrical disconnect (see the National Electric Code). Prom inently post s afety informati on, including signs showing the source of electrical disconnect.

ËPersonnel

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.

—Inform personnel about hazard avoidance and the importance of care and common sense. Provide

ËSafety Devices

Do not allow machine to be used with any missing guard or cover. Service any failing or malfunctioning device before operating the machine.

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

—Ensure that no one eliminates or disables any safety device on t he machine or in this facilit y.

ËMaintenance

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.

—Ensure the machine is inspected and serviced in accordance with the norms of good practice and

ÊHazards During Installation

ELECTROCUTION HAZARD—Contact with high voltages can kill or seriously injure you.

☞ All electrical connections must be made by a competent electrician.

EQUIPMENT DAMAGE HAZARD—Machine can be damaged if shipping restraints are improperly utilized. These include various bolts, brackets, and safety stands (painted red), brake blocks and the vibration safety switch (tie wrapped).

☞ DO NOT remove shipping restraints until installation is complete. ☞ DO remove all shipping restraints before operating machine.

ÊHazards During Service and Maintenance

ELECTROCUTION HAZARD—High voltage is present inside electric boxes, motors and many other components. Power switches on machine control panels disable only control circuit power in certain boxes. You can be killed or seriously injured on contact with high voltage.

☞ Lock OFF and tag out power at the wall di sconnect before ser vici ng, except w her e spe-

cifically instructed otherwise in this manual.

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 specifical ly instr ucte d otherwis e in this manua l.

☞ Insure belt guards are in place during service procedures.

MULTIPLE HAZARDS—Failure to maintain machine in proper working order can result in

fatal or serious injury to operators and/or damage to property. DO NOT permit operation under any of the following circumstances:

☞ Malfunctioning door interlock mechanism. ☞ Malfunctioning limit switches. ☞ Malfunctioning two hand inching. ☞ Any evidence of cylinder damage. ☞ Missing or removed guards, covers, or side panels. ☞ Malfunctioning tilting components, including but not limited to safety limit switches,

electrical interlocks, and operator controls.

☞ If any of these conditions occur:

• The machine makes a sound like skidding automobile tires as it comes out of extract.

• The wash or drain clutch does not disengage or it reengages during extract.

• V-bel ts jum p off at the start of, during, or at the end of extract.

• A strange whining sound occurs at any time during extract.

BURN HAZARD — Machines equipped with heat exchangers and their associated piping may be hot enough to burn body parts on contact.

☞ Provide safety guards, fences, restraints, or covers as required to isolate hot

surfaces.

ÊAdditional Hazards During Tilting Machine Maintenance

CRUSH/SEVER HAZARD—Tilting mechanisms 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 ins tal led.

CRUSH/SEVER HAZARD—Tilting machines with tilt wheels/cradles may lunge forward or rearward and even fall ove r if the tilt wheels at the non-tilted end are r aised out of their cradles—killing/ injuri ng 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 hydraul ic

valves.

☞ NEVER permit operation with malfunctioning tilt limit switches.

About the Forces Transmitted by Milnor® Washer-extractors

About the Forces Transmitted by Milnor Washer-extractors

During washing and extracting, all washer-extractors transmit both static and dynamic (cyclic) forces to the floor, foundation, or any other supporting structure. During washing, the impact of the goods as they drop imparts forces which are quite difficult to quantify. Size for size, both rigid and flexibly-mounted machines transmit approximately the same forces during washing. During extracting, rigid machines transmit forces up to 30 times greater than equivalent flexibly-mounted models. The actual magnitude of these forces vary according to several factors:

• machine size,

• final extraction speed,

• amount, condition, and type of goods being processed,

• the liquor level and chemical conditions in the bath preceding extraction, and

• other miscellaneous factors. Estimates of the maximum force normally encountered are available for each Milnor

and size upon request. Floor or foundation sizes shown on any Milnor on-grade situations based only on previous experience without implying any warranty, obligation, or responsibility on our part.

Rigid Machines

Size for size, rigid washer-extractors naturally require a stronger, more rigid floor,

foundation, or other supporting structure than flexibly-mounted models. If the supporting soil under the slab is itself strong and rigid enough and has not subsided to leave the floor slab suspended without support, on grade installations can often be made directly to an existing floor slab if it has enough strength and rigidity to safely withstand our published forces without transmitting undue vibration. If the subsoil has subsided, or if the floor slab itself has insufficient strength and rigidity, a deeper foundation, poured as to become monolithic with the floor slab, may be required. Support pilings may even be required if the subsoil itself is “springy” (i.e., if its resonant frequency is near the operating speed of the machine). Above-grade installations of rigid machines also require a sufficiently strong and rigid floor or other supporting structure as described below.

Flexibly-mounted Machines

Size for size, flexibly-mounted machines generally do not require as strong a floor,

foundation, or other supporting structure as do rigid machines. However, a floor or other supporting structure having sufficient strength and rigidity, as described in section 3, is nonetheless vitally important for these models as well.

How Strong and Rigid?

Many building codes in the U.S.A. specify that laundry floors must have a minimum live

load capacity of 150 pounds per square foot (732 kilograms per square meter). However, even compliance with this or any other standard does not necessarily guarantee sufficient rigidity. In any event, it is the sole responsibility of the owner/user to assure that the floor and/or any other supporting structure exceeds not only all applicable building codes, but also that the floor and/or any other supporting structure for each washer-extractor or group of washer-extractors actually

has sufficient strength and rigidity, plus a reasonable factor of safety for both, to support the

weight of all the fully loaded machine(s) including the weight of the water and goods, and including the published 360º rotating sinusoidal RMS forces that are transmitted by the machine(s). Moreover, the floor, foundation, or other supporting structure must have sufficient rigidity (i.e., a natural or resonant frequency many times greater than the machine speed with a reasonable factor of safety); oth erwise, the m enti oned 360º ro ta ting sinuso ida l RMS forces can be multiplied and magnified many times. It is especially important to consider all potential vibration problems that might occur due to all possible combinations of forcing frequencies (rotating speeds) of the machine(s) compared to the natural frequencies of the floor and/or any other supporting structure(s). A qualified soil and/or structural engineer must be engaged for this purpose.

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.
