Pumping from Draft
WARNING
!
Pressure Hazard. May result in personal injury or
death.
Prior to connection of hoses, caps or other closures
with pump intake or pump discharge connections, re‐
lieve pressure by opening drains.
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 even for a few minutes
completely closed it may heat the water enough to
scald someone when the valve is opened. Overheat‐
ing 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 over‐
heating, opening a discharge valve may be unneces‐
sary.
WARNING
!
Unexpected Truck Movement. May result in per‐
sonal injury or death.
Failure to properly shift transmission in accordance
with the transmission operating instructions may result
in unexpected truck movement which may result in
serious personal injury or death.
To get full capacity, quick prime and maintain pump effi‐
ciency:
a) Position vehicle as near as possible to water sup‐
ply.
b) Avoid humps and sharp bends in intake hose.
Make sure no part of hose is higher than pump
intake inlet. (Air pockets in intake hose may cause
loss of prime or erratic pump action, and may re‐
duce pump capacity.)
c)
Make sure all intake connections are tight and
discharge valves are closed.
d) Immerse intake strainer at least two feet below
water surface to prevent pump from drawing air.
(Whirlpools forming above intake strainer indicate
that strainer is too close to surface of water.)
e) Make sure intake strainer is far enough from bot‐
tom to prevent sand, gravel and other foreign
matter from being drawn into the pump.
1.
Engage pump in accordance with transmission in‐
structions.
2.
Prime the pump (see separate instructions supplied
with primer).
3.
Open discharge valves, and accelerate engine to ob‐
tain desired discharge pressure and capacity.
4.
Set relief valves or other pressure governing device to
desired pressure.
NOTE: For extra pressure stage pumping instruc‐
tions, see page 8.
After Pumping
WARNING
!
Pressure Hazard. May result in personal injury or
death.
Prior to removal of hoses, caps or other closures with
pump intake or pump discharge connections, relieve
pressure by opening drains.
1.
Disengage pump drive in accordance with transmis‐
sion instructions.
2.
If pumping anything but clean water, remove all intake
and discharge caps, open all valves and open all
drains. Flush entire system with clean, fresh water for
several minutes to remove all traces of impurities.
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
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.
