Pressure Hazard. May result in personal injury.
Prior to connection or removal of hoses, caps or
other closures with pump intake or pump discharge
connections, relieve pressure by opening drains or
bleeder valves. Bleeder valves should also be used
while filling a hose connected to an intake with water.

WARNING
Scalding Water Hazard. May result in serious burns.
When operating the pump, be sure to open at least
one discharge valve slightly to prevent the pump from
overheating. If the pump runs for a few minutes com-
pletely closed, it may heat the water enough to scald
someone when the valve is opened. Overheating can
damage the packing, seals and other pump parts. If
the apparatus builder has installed a by-pass system
or other provision designed to prevent overheating,
opening a discharge valve may be unnecessary.
!
WARNING
Unexpected Truck Movement. May result in seri-
ous personal injury or death.
Failure to properly shift transmission in accordance to
the transmission operating instructions may result in
unexpected truck movement which may result in seri-
ous personal injury or death.

WARNING
CAUTION
If pump has a mechanical seal, limit intake pressure
to 100 psi if possible. Although the pump will operate
properly with higher intake pressure, such operation
will greatly accelerate mechanical seal wear.
Pumping from Hydrant or in Relay
3. Open discharge valves and accelerate engine to
obtain desired discharge pressure and capacity.
4. Set relief valves or other pressure governing de-
vice to desired pressure.
CAUTION
Do not attempt to pump more water than is available
from the water tank. Always make sure the intake
pressure compound gage reading stays above zero.
NOTE: Some fire departments operate at a minimum
intake pressure of 10 psi (.7 bar) when pumping
from hydrant or in relay to prevent a
“soft” intake
hose from collapsing.
After Pumping
1. Engage pump. If pump is equipped with a Water-
ous transmission (C10, C20, K, PA, T, Y), follow
transmission operation instructions.
2. Open intake, hydrant and other valves as neces-
sary to allow water to enter the pump.
NOTE: Bleeder valves should be used while filling
a hose connected to an intake with water.
1.
Disengage pump. If pump is equipped with a Wa-
terous transmission (C10, C20, K, PA, T, Y), follow
transmission operation instructions.
2. If pumping anything but clean water, remove all in-
take and discharge caps, open all valves and open
all drains. Flush entire system with clean, fresh wa-
ter for several minutes to remove all traces of im-
purities.
3. If pump is kept full of water when not in use, make
sure water is clean and non-corrosive. Make sure
the pump is completely full or completely drained
(never partially full).
CAUTION
Freezing water hazard. May cause damage to the
pump.
If the pump is exposed to freezing temperatures,
drain all water from pump, lines and accessories.
4. Close all drains and install intake and discharge
caps.
5. If truck is equipped with a priming pump, operate
it until fluid is discharged from priming pump dis-
charge pipe. Also check fluid level in priming tank,
and refill if necessary.
Pressure Hazard. May result in personal injury.
Prior to connection or removal of hoses, caps or
other closures with pump intake or pump discharge
connections, relieve pressure by opening drains or
bleeder valves. Bleeder valves should also be used
while filling a hose connected to an intake with water.
