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.
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.
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 over- heating, opening a
discharge valve may be unnecessary.

WARNING
Unexpected Truck Movement. May result in
personal 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.
NOTE: To get full capacity, quick prime and maintain
pump efficiency:
a) Position vehicle as near as possible to water supply.
b) Avoid humps and sharp bends in intake hose. Make
sure no part of hose is higher than pump inlet. (Air
pockets in intake hose may cause loss of prime or
erratic pump action, and may reduce 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 bottom to
prevent sand, gravel and other foreign matter from
being drawn into the pump.
1. Prime the pump (see separate instructions supplied
with primer).
2. Engage pump drive.
3. Open discharge valves, and accelerate engine to
obtain desired discharge pressure and capacity.
4. Set relief valves or other pressure governing device
to desired pressure.
1. Disengage pump drive.
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.
NOTICE
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 discharge
pipe. Also check fluid level in priming tank, and refill
if necessary.
