Revision 3
II.
Preventive Maintenance Intervals
The basic "tool"
of
preventive maintenance is visual inspection. During this inspection,
screws should be tightened, adjustments done
if
needed, component wear noted, modest
amount
of
lubrication performed, etc.
The following pages provide guidelines for visual inspection, preventive maintenance and
adjustment instructions for the high pressure water jetting unit. Inspect each component at
the suggested interval. If, upon inspection, a component needs adjustment, lubrication
or
replacement, perform the required maintenance as part
of
the preventive maintenance
program.
Service intervals specified are for operating hours with moderate temperatures unless
otherwise specified.
It
should be noted that service intervals should be adjusted accordingly
for operation in abnormal environmental conditions. The suggested service intervals are for
the purpose
of
illustration only.
It
is
very important that each component be checked.
Special attention should be given to the high pressure pump, in particular, the lubricant level.
Note:
Even though the indicated interval for the high pressure pump crankcase oil change
is
every 500 hours
or
six
(6)
months, the first change should be
at
125 hours. See
IV: Lubrication Instructions in this section.
Note:
