Revision 3
3.
Corrosive Vapors
Care should be made
to
eliminate the exposure
of
the high pressure water jetting unit
to
corrosive gases to prevent contamination
of
the high pressure pump's power end.
4.
High Humidity
High pressure water jetting units exposed
to
high humidity, unless operated continuously,
will accumulate condensation in the the high pressure pump's power end and oil plunger
lubricator. Take periodic oil samples from the drain connections.
If
water
is
detected, then
the oil must be changed.
D.
Safety
The subject
of
safety has been discussed elsewhere in this manual. The reader is referred to
Section 2:
SAFETY
and
to
other cautions and warnings to be found throughout this manual.
However, because preventive maintenance requires such close contact with the high pressure
water jetting unit, caution must be exercised every minute. Here is a brief review
of
some
of
the safety basics before delving more deeply into preventive maintenance:
• Remove any loose objects such as trash and oily rags from the work area.
• Safety begins with you. Make sure that all equipment has finished operating and has
been shut-down before beginning work.
• Wear protective glasses and protective shoes when working.
• Do not wear loose-fitting or torn clothing. Remove all jewelry when working.
• Do not engage in, nor tolerate, horseplay in the work area.
• Review all safety information pertaining to the work you are about to
do.
• All electrical components associated with this system are to be maintained in accordance
with approved practices. Never use jumper wires across fuses, fuse holders or circuit
breakers.
• Do not work on anything that is supported ONLY by lifting jacks or a hoist. Always
use blocks or proper stands
to
support the product before performing any service work.
• Dump all high pressure before any lines, fittings, or related items are removed or
disconnected. Be alert for possible pressure when disconnecting any device from a
system that utilizes pressure.
