Maintenance Program
C&D Zodiac ACD has implemented a program consisting
of five (5) disparate functions to accomplish the goals of
our Maintenance Program.
Planned Maintenance (Proactive)
1. Predictive Maintenance
2. Preventive Maintenance
3. Improvement Maintenance
4. Corrective maintenance
Unplanned Maintenance (Reactive)
1. Emergency / Breakdown maintenance
These functions assist in the identification and reduction of production
impacting equipment, system and facility failures. Each of these
functions utilizes a system for collecting, recording and analyzing data
with the goal of reducing production down time.

Predictive Maintenance
Predictive maintenance can be broken down into two major
categories.
Statistics-based predictive maintenance analyses data
gathered during proactive and reactive maintenance
activities to aide in the determination of patterns of failure.
This allows CDZ to Adjust PM Cycles and focus on areas
that will minimize or eliminate future failures
Condition-based predictive maintenance, evaluates the
condition of equipment by performing periodic or
continuous equipment condition monitoring. The ultimate
goal is to perform maintenance at a scheduled point in
time when the maintenance activity is most cost-effective
and before the equipment loses performance within a
given threshold.

Preventive Maintenance
CDZ is currently implementing a corporate level plan to
increase the operator’s ownership and responsibility for a
portion of a given machine's maintenance. This program is
currently in use on CNC equipment and Paint booths and will
be expanded as data is gathered and the program adjusts
based on that data. Operators are assigned responsibility for
daily visual inspections of critical fluids as well as machine
condition and operation, routine maintenance such as filter
changes and lubrication, cleaning and the reporting of any
issues outside of their identified responsibilities. The PM
Forms are kept in a folder attached to the machine and
updated by both the Operators and the maintenance staff.

Preventive Maintenance
(Continued)
1. In Conjunction with the corporate program CDZ ADC utilizes a software
package called MaintainIt to generate and store PM work orders. All
Capital equipment is assigned a designation in the MaintainIt database
and appropriate intervals are set up for tickets to be generated. This can
be weekly, bi-weekly, monthly, quarterly, etc. based on the current
utilization of the equipment. Initially this is determined by the
manufacturer’s recommendations but as the equipment ages or hours of
operation are modified, the cycles are altered to adjust for these
changes. Each work order includes a checklist of items to be cleaned,
serviced or replaced as well as space to record materials used and man
hours needed to complete the defined tasks. All records are kept in both
hard copy and in the MaintainIt database and can be reviewed as needed.
If Issues beyond the scope of the PM work order are identified, the
technician files a request through the Unplanned / Breakdown
Maintenance system and the work is scheduled based on criticality and
production requirements.

Improvement Maintenance
The information that is collected and analyzed is also used
to determine ways in which future maintenance issues can
be minimized or eliminated. This can include alterations or
improvements to support equipment, location and floor
space requirements, purchase of equipment that requires
little or no maintenance, among a host of other possible
ways that these issues can be avoided in the future. The

Corrective Maintenance
Information from Preventive, Predictive and Unplanned /
Breakdown Maintenance programs is collected, analyzed
and subsequently used to identify areas of operation,
equipment or systems that require further attention to
improve on performance or reduce failure rate and thus
reduce production impact. This can include modifications
to facility systems, Alterations to PM cycles or attention to
particular areas of a piece of equipment. The data can
also be used to identify process issues in operations,
production and maintenance as well as affecting future
equipment purchases and identifying previously
unidentified critical spares.

Unplanned / Breakdown Maintenance
C&D Zodiac ACD currently utilizes a SharePoint database
created specifically for processing equipment and facility
repairs, modifications, installations, relocations and
fabrication requirements. Each request is processed
through a series of checks and balances to determine the
criticality of the issue and to schedule the required
personnel and arrange for the needed equipment time to
complete the work. This database is equipped with a
knowledge base designed to record any critical
information that might be required in a future repair as
well as any documentation or vender information on the
equipment.

Unplanned / Breakdown Maintenance
(Continued)
Part and material requisition tracking and current status as
well as estimated and actual man-hours, equipment
downtime and numerous other details are recorded in order
to aid in communications with the production and
management personnel affected by the work as well as for
analysis and subsequent improvement of the maintenance
process and identification of potential problems with
equipment throughout the plant.

15. CABIN INTERIORS / DIVISION
Corrective Maintenance
Information from the Operations, Preventative and Unplanned /
Breakdown Maintenance programs is collected, analyzed and
subsequently used to identify areas of operation, equipment or
systems that require further attention to improve on
performance or reduce failure rate and thus reduce production
impact. This can include modifications to facility systems,
Alterations to PM cycles or attention to particular areas of a
piece of equipment. It can also be used to identify process
issues in operations, production and maintenance as well as
affecting future equipment purchases and identifying previously
unidentified critical spares.

Critical Spares
Critical Spares: C&D Zodiac ACD Equipment and Facilities
Maintenance Teams work continuously to identify and maintain a
stock of critical spare parts, materials and supplies in anticipation of
a production critical repair. Baseline critical spares are identified at
the time of purchase for any new equipment coming into the facility.
Established equipment critical spares are determined by analysis of
data gathered over time through the use of the TPM process. This
data is reviewed on an ongoing basis and spares are purchased
based on both, frequency of failure, impact to production, cost, and
availability, shipping cost and delay as well as many other criteria.
