2.1.1. General Safety Requirements—Vital Information for

Management Personnel

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 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 and CE in Europe) hold the owner/user ultimately responsible for maintaining a safe working environment. Therefore, the owner/user must do or ensure the following:

• recognize all foreseeable safety hazards within his facility and take actions to protect his personnel, equipment, and facility;

• work equipment is suitable, properly adapted, can be used without risks to health or safety, and is adequately maintained;

• where specific hazards are likely to be involved, access to the equipment is restricted to those employees given the task of using it;

• only specifically designated workers carry out repairs, modifications, maintenance, or servicing;

• information, instruction, and training is provided;

• workers and/or their representatives are consulted.

[Document BIUUUS04]

Work equipment must comply with the requirements listed below. The owner/user must verify that installation and maintenance of equipment is performed in such a way as to support these requirements:

• control devices must be visible, identifiable, and marked; be located outside dangerous zones; and not give rise to a hazard due to unintentional operation;

• control systems must be safe and breakdown/damage must not result in danger;

• work equipment is to be stabilized;

• protection against rupture or disintegration of work equipment;

PELLERIN MILNOR CORPORATION

Chapter 2. Safety

• guarding, to prevent access to danger zones or to stop movements of dangerous parts before the danger zones are reached. Guards to be robust; not give rise to any additional hazards; not be easily removed or rendered inoperative; situated at a sufficient distance from the danger zone; not restrict view of operating cycle; allow fitting, replacing, or maintenance by restricting access to relevant area and without removal of guard/protection device;

• suitable lighting for working and maintenance areas;

• maintenance to be possible when work equipment is shut down. If not possible, then protection measures to be carried out outside danger zones;

• work equipment must be appropriate for preventing the risk of fire or overheating; discharges of gas, dust, liquid, vapor, other substances; explosion of the equipment or substances in it.

2.2. Prevent Damage From Chemical Supplies and Chemical Systems

This document uses Simplified Technical English. Learn more at http://www.asd-ste100.org.

All Milnor® washer-extractors and CBW® tunnel washers use stainless steel with the AISI 304 specification. This material gives good performance when chemical supplies are correctly applied. If chemical supplies are incorrectly applied, this material can be damaged. The damage can be very bad and it can occur quickly.

Chemical supply companies usually:

• supply chemical pump systems that put the supplies in the machine,

• connect the chemical pump system to the machine,

• write wash formulas that control the chemical concentrations.

The company that does these procedures must make sure that these procedures do not cause damage. Pellerin Milnor Corporation accepts no responsibility for chemical damage to the

machines it makes or to the goods in a machine.

2.2.1. How Chemical Supplies Can Cause Damage

2.2.1.1. Dangerous Chemical Supplies and Wash Formulas—Some examples that can

cause damage are:

• a very high concentration of chlorine bleach,

• a mixture of acid sour and hypo chlorite,

• chemical supplies (examples: chlorine bleach, hydrofluosilicic acid) that stay on the stainless steel because they are not quickly flushed with water.

The book “Textile Laundering Technology” by Charles L. Riggs gives data about correct chemical supplies and formulas.

2.2.1.2. Incorrect Configuration or Connection of Equipment—Many chemical systems:

• do not prevent a vacuum in the chemical tube (for example, with a vacuum breaker) when the pump is off,

• do not prevent flow (for example, with a valve) where the chemical tube goes in the machine.

Damage will occur if a chemical supply can go in the machine when the chemical system is off. Some configurations of components can let the chemical supplies go in the machine by a siphon (Figure 2). Some can let chemical supplies go in the machine by gravity (Figure 3).

2.2.2. Equipment and Procedures That Can Prevent Damage

2.2.2.1. Use the Chemical Manifold Supplied.—There is a manifold on the machine to attach

chemical tubes from a chemical pump system. Figure 3 shows examples. The manifold has a source of water to flush the chemical supplies with water.

Figure 4: Examples of Manifolds for Chemical Tubes. Your equipment can look different.

PELLERIN MILNOR CORPORATION

Chapter 2. Safety

2.2.2.2. Close the line.—If the pump does not always close the line when it is off, use a shutoff valve

to do this.

2.2.2.3. Do not let a vacuum occur.—Supply a vacuum breaker in the chemical line that is higher

than the full level of the tank.

2.2.2.4. Flush the chemical tube with water.—If the liquid that stays in the tube between the

pump and the machine can flow in the machine, flush the tube with water after the pump stops.

2.2.2.5. Put the chemical tube fully below the machine inlet.—It is also necessary that

there is no pressure in the chemical tube or tank when the system is off. Figure 5 shows this configuration.

Schematic View Legend

I. Chemical inlet on the

machine

L. Chemical tube P. Pump T. Chemical tank

2.2.2.6. Prevent leaks.—When you do maintenance on the chemical pump system:

• Use the correct components.

• Make sure that all connections are the correct fit.

• Make sure that all connections are tight.

3.1. Routine Maintenance—36- and 42-series, Rubber Spring-hung Washer-extractor

This document uses Simplified Technical English. Learn more at http://www.asd-ste100.org.

Do the maintenance in Section 3.1.2 “Maintenance Summary” to make sure that the machine is safe, keeps the warranty, and operates correctly. This will also decrease repair work and unwanted shutdowns. Speak to your dealer or Milnor if repairs are necessary.

WARNING 20 : Risk of severe injury—Mechanisms can pull in and mutilate your body.

• You must be approved by your employer for this work.

• Use extreme care when you must examine components in operation. Remove power from

the machine for all other work. Obey safety codes. In the USA, this is the OSHA lockout/tagout (LOTO) procedure. More local requirements can also apply.

• Replace guards and covers that you remove for maintenance.

3.1.1. How To Show the Maintenance On a Calendar

If you use software to keep the maintenance schedule for your plant, add the items in Section

3.1.2 to that schedule. If not, you can put marks on a calendar that work with the tables in Section

3.1.2. The marks are the numbers 2, 3, 4, 5, and 6. It is not necessary to show the number 1 (items

you do each day) on the calendar. The number 2 = items you do each 40 to 60 hours, 3 = each 200 hours, 4 = each 600 hours, 5 = each 1200 hours, and 6 = each 2400 hours. These are the "Mark" numbers at the top of the narrow columns on the left of each table in Section 3.1.2.

Table 1 shows where to put the marks on a calendar. For example, if your machine operates

between 41 and 60 hours each week, the first three marks are 2, 2, and 3. Put these marks on the first, second, and third weeks after the machine starts operation. If you do routine maintenance on a given day of the week, put the mark on that day of each week. Continue to put marks on the subsequent weeks. It can be necessary to do the 40 to 60 hour (2) maintenance more than one time each week. If the machine operates between 61 and 100 hours, put a 2 on two days of the week. If the machine operates 101 or more hours, put a 2 on three days of the week.

On each date with a 3, do the items with an x in the 3 or the 2 column of each table in Section

3.1.2. On each date with a 4, do the items with an x in the 4, 3, or 2 column. Continue this

pattern.

3.1.4. Lubricant Identification and Procedures

Table 9 identifies the lubricant for each lubricant code given in the maintenance summary. Get

these or equivalent lubricants from from your local lubricant supplier.

PELLERIN MILNOR CORPORATION

Chapter 3. Routine Maintenance

When you add grease, always use the procedures given in Section 3.1.4.1. When you add grease to motors, also use the procedures given in Section 3.1.4.3.

CAUTION 21 : Risk of damage—Bad lubricant will decrease the life of components.

• Make sure that all equipment and fittings used to apply lubricants are clean.

• Use only the given lubricants or equivalent lubricants that have the same specifications.

Application Example

3.1.4.1. Grease Gun Procedures

CAUTION 22 : Risk of damage—Hydraulic pressure can push out seals and push grease

into unwanted areas (example: motor windings).

• Use a hand grease gun. A power grease gun gives too much pressure.

• Know the quantity of grease your grease gun gives each cycle (each stroke).

• Operate the grease gun slowly (10 to 12 seconds for one cycle).

• Add only the specified quantity. Stop if new grease come out of a drain port or other opening.

• Remove spilled grease from belts and pulleys.

The tables give grease quantities in fluid ounces (fl oz) and milliliters (mL). You can also use grease gun cycles (strokes). A cycle is each time that you pull the trigger. One cycle is usually approximately 0.06 fl oz (1.8 mL). Your grease gun can give more or less than this. Measure the output of your grease gun as follows:

1. Make sure that the grease gun operates correctly.

2. Operate the grease gun to put grease into a small container with fluid ounce or milliliter increments. Pull the trigger fully and slowly.

3. Add a sufficient quantity of grease to measure accurately. Count the number of cycles of the grease gun (the number of times that you pull the trigger).

4. Calculate the quantity for each cycle of the grease gun.

Example: 2 fl oz / 64 cycles = 0.031 fl oz for each cycle

Example: 59 mL / 64 cycles = 0.92 mL for each cycle

3.1.4.2. Procedures for Bearing Components Connected to a Grease Plate—Your

machine has a grease plate on the machine housing or the shell. You add grease to components of the bearing housing at this location. The correct procedure is to add grease when the cylinder turns at wash speed, but obey these precautions:

• For all other grease maintenance, add grease with power removed from the machine.

• If the grease plate on your machine is not serviceable (if you must add grease at a different location), add grease with power removed from the machine.

• If you must remove a guard to get access to the grease plate, prevent access to the machine by other personnel.

PELLERIN MILNOR CORPORATION

Chapter 3. Routine Maintenance

If you obey these precautions, use the Manual mode to operate the machine at wash speed. Then add grease at the grease plate.

3.1.4.3. Procedures for Motors—If a motor on your machine does not have grease fittings, no

grease maintenance is necessary. If a motor on your machine has grease fittings, it is necessary to add grease. But the interval is usually longer than for other maintenance. Table 10 gives motor grease intervals and quantities for motors with specified frame sizes and speeds. You get this data from the motor nameplate. Use Table 6 in Section 3.1.2 to record the data for the motors on your machine.
