hose connections are tight, properly
supported and secure before operation.
Do not operate the pump against a
closed discharge valve. If operated
against a closed discharge valve, pump
components will deteriorate, and the
liquid could come to a boil, build pres­
sure, and cause the pump casing to rup­
ture or explode. Momentary closure of a
discharge valve is acceptable only
when required for startup or shutdown
procedures.
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an over­
heated pump. Vapor pressure within the
pump can cause parts being disen­
gaged to be ejected with great force. Al­
low the pump to cool completely before
servicing.
This pump may be used to handle mate­
rials which could cause illness through
direct exposure or emitted fumes. Wear
adequate protective clothing when
working on the pump or piping.
Do not operate the pump without guards
in place over the rotating parts. Ex­
posed rotating parts can catch clothing,
fingers or tools, causing severe injury to
personnel.
Make sure the pump is level. Lower jack
stands and chock the wheels, if so
equipped. Use caution when positioning
the skid‐mounted unit to prevent damage
to the fuel tank.
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating an internal combustion
engine in an enclosed area, make sure
exhaust fumes are piped to the outside.
These fumes contain carbon monoxide,
a deadly gas that is colorless, tasteless
and odorless.
Fuel used by internal combustion en­
gines presents an extreme explosion
and fire hazard. Make certain that all
fuel lines are securely connected and
free of leaks. Never refuel a hot or run­
ning engine. Avoid overfilling the fuel
tank. Always use the correct type of fuel.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. Refer to the performance
curve on page E-1 for the maximum
continuous operating speed for this
pump.
The engine used on this unit is equipped
with an exhaust filter which reduces the
amount of nitrogen oxide produced while
burning away particulate matter that would
