Maintenance
Misguided
Maintenance
Over time, maintenance programs may become seriously
"out of calibration" and consequently waste precious maintenance
dollars. For example, some preventive maintenance (PM) procedures get
"simplified" via dropping steps while others become bloated from "step
creep." If the original reason for those dropped steps still exists,
the
PM is now inadequate. New steps and text of a bloated PM may have
seemed
helpful when added, but the overall effect is a PM that gets in its own
way.
Take the following for example: A department manager complains about
Line B reliability. To keep the peace, someone increases the PM
frequency. However, if the cause is outside what the PM addresses (and
it probably is), the increased frequency consumes resources and raises
risk of human-caused failure while not fixing the problem about which
the department manager complained.

Troubleshooting Quiz
One of the production machines cuts, bends, and stamps
steel. A 50-hp motor is at the heart of this machine. Not long ago,
product quality problems were traced back to motor vibration.
Tightening
the mounting bolts didn't stop the vibration, so the motor was
replaced.
Within a few days, however, the new one started vibrating as well.
With only this information to go on, can you determine what steps
you should take to troubleshoot this motor vibration problem?
Visit EC&M's
Web site to see the answer.
Make Procedures
Helpful, Part 1
If isolated from the realities of the field, repair
procedures become useless exercises in bureaucracy rather than tools
for
making faster, better repairs. Grade the performance of your repair
procedures by observing whether people even use them. Then observe
how they use them. If the repair techs treat the procedures as
tools for doing the job right, you probably have good procedures. If
not, your procedures need overhauling.
One thing that frustrates procedure users is being forced to flip
pages back and forth. The primary benefit of a repair procedure is it
helps a person do the right steps in the right order. If the procedure
doesn’t flow in a linear fashion, that doesn’t happen.

Motors and Drives Solutions
Motors and drives
are critical elements of most machines. Visit the Fluke solution center
as a resource for all your motor and drive issues. Here you will find
application notes, case studies, an on-line discussion board, videos
and
other resources to help you deal with these complex and important
issues. www.fluke.com/motorsdrives
Operation
NEC in the
Facility
You can learn of Code violations in all kinds of ways,
not just through formal inspections. For example, a contractor's rep
tells you about a Code violation that one of the firm's electricians
ran
across incidentally while working at your facility.
Such impromptu inspections give you a chance to fix things before
your insurance company discovers them and issues the typically
ill-timed
conformance notice. They also give you a chance to fix Code violations
before they turn into reportable events, such as a fatal fire.
Encourage
such inspections by taking them seriously.

Safety
Hearing loss isn't inevitable. Many people maintain
sharp hearing well into old age. Yet, other people exhibit profound
hearing loss while barely into middle age.
Profound hearing loss isn't a natural consequence of aging. It is,
however, a natural consequence of not wearing PPE when circumstances
dictate. That doesn't mean just on the job. Using a lawnmower or leaf
blower without hearing protection causes hearing damage, and it can be
permanent.
If you must raise your voice to carry on a conversation, you need
hearing protection. This is true even if there isn’t a "Hearing
Protection Required" sign anywhere in the area. Your ears don't become
magically immune to damage just because there's no sign posted. Nor
does
the ear-damaging noise give you a free pass simply because you're off
the clock or just passing through. Once the damage happens, it's
permanent.
