2.1. Safety—
2.1.1. General Safety Requirements—Vital Information for
Management Personnel[Document BIUUUS04]
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.
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;
12

Chapter 2. Safety
PELLERIN MILNOR CORPORATION
• 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.
2.1.1.1. Laundry 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. 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.
2.1.1.2. Personnel—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 personnel use proper safety and operating procedures. Verify that personnel
understand and abide by the warnings on the machine and precautions in the instruction manuals.
2.1.1.3. Safety Devices—Ensure that no one eliminates or disables any safety device on the machine
or in the facility. Do not allow machine to be used with any missing guard, cover, panel or door.
Service any failing or malfunctioning device before operating the machine.
2.1.1.4. Hazard Information—Important information on hazards is provided on the machine safety
placards, in the Safety Guide, and throughout the other machine manuals. Placards must be kept
clean so that the information is not obscured. They must be replaced immediately if lost or
damaged. The Safety Guide and other machine manuals must be available at all times to
the appropriate personnel. See the machine service manual for safety placard part numbers.
Contact the Milnor Parts department for replacement placards or manuals.
2.1.1.5. Maintenance—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.

2.2. How To Use the Safety Stands on the Rubber Spring-resting,
Hydraulic-tilt Washer-extractor
These machines are provided with two safety stands (painted red) for maintenance. After the shell
is tilted up, the stands are placed around the tilt cylinder shafts. Use the safety stands to perform
maintenance on the machine when it is tilted.
WARNING 16 : Crush Hazard—The safety stands provide protection against the
un-powered drifting down of the shell during maintenance in the event of a leak in the hydraulic
system.
• Never work under the raised shell or housing unless both safety stands are installed and
power is locked out/tagged out. Do not work near the raised shell or housing with power
on unless both safety stands are installed.
• Install these safety components using the procedure prescribed in this document.
• Maintain these safety components in good condition.
• Designate a convenient, secure area to stow these safety components when not in use.
