Preventative Maintenance
Schedule
A preventative maintenance program serves to antici-
pate maintenance issues prior to waiting until the system
requires service. Like changing the oil & filters in an
automobile, by choosing to service the various parts and
operation in the Sampling System at regular intervals,
the technician can perform the maintenance service
when desired, rather than when required, such as in the
middle of night.
The key is to perform maintenance before it is required.
The preventative maintenance schedule implemented
should consider the application of the sampler. Many of
these considerations include: the weather environment;
the condition of, the actuation gas, the product condition
and quality, and the pump stroke frequency. All of these
issues must be considered when establishing a preven-
tative maintenance schedule.
