Preventive Maintenance
There are many procedures that need to be followed or reviewed when performing
Preventive Maintenance checks and replacements. Included are some general
guidelines for cleaning areas of the instrument with a bleach solution, lubricating
tips, and a reference list of PM procedures that are categorized by the instrument
system.
Cleaning with a Bleach Solution
Follow the guidelines below to create the proper concentration of bleach solution for
cleaning.
• Obtain a convenient quantity of bleach solution (available in one-gallon or about
3.3-liter volume).
• Note the concentration of the active ingredient, sodium hypochlorite (NaOCl) as
provided on the label. Normally the concentration of commercially available
bleach solution is 5.25%.
• Dilute the bleach solution to obtain a final active ingredient concentration of about
1.0%. To dilute the solution, make a five-fold dilution using 1.0 part original
bleach solution and 4.0 parts distilled or deionized water.
Note: Sometimes the 1.0% has been referred to as 20%. This is based on the
premise that the original bleach solution is 100% and a five-fold dilution of it
results in a 20% concentration.
Lubricating Components
Note: Lubricate with Tufoil¨ Compu-Lube or equivalent unless otherwise specified
in the PM Checklist.
