F-1031, Section 2119
Page 2 of 24
Death or serious personal injury might occur if proper
operating procedures are not followed. The pump op-
erator, as well as individuals connecting supply or
discharge hoses to the apparatus must be familiar
with these pump operating instructions as well as
other operating instructions and manuals for the ap-
paratus, water hydraulics and component limitation.
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.
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.
Hose Pressure Hazard.
May cause serious personal injury.
Use only fire hose that is rated at 200 PSI (12.8 bar)
or higher working pressure.
Air Discharge Hose and Nozzle Heat Hazard.
May cause severe burns.
Hose and nozzle used for air discharge will be-
come hot due to the hot air flowing through it.
Wear protective gloves. Also be prepared for noz-
zle reaction when air discharge and nozzle are
opened.
Air Source Hazard.
May cause serious personal injury or death.
Do not use the compressed air foam unit as an air
source for any self-contained breathing apparatus
(SCBA) or any breathing air supply.
“Slug Flow” Hazard.
May cause personal injury to the hose operator.
Foam concentrate must be present before the pres-
ence of compressed air to prevent the condition known
as “slug flow.” If foam concentrate is not present, un-
mixed water and air will be discharged through the
nozzle in an erratic matter.
Pressure Hazard.
May cause serious personal injury.
Discharge outlets that are capped, hose lines that are
valved and charged and the air compressor sump
may contain compressed air. Relieve all pressure be-
fore attempting to remove any caps, fittings, nozzles
or to perform maintenance to prevent serious injury.
Nozzle Reaction Force Hazard.
May cause personal injury to the hose operator.
Nozzle reaction force is significantly increased at the
time the nozzle is opened in compressed air foam op-
eration. Open CAFS nozzles slowly.

OTICE
When towing, disconnect the drive shaft that con-
nects the pump transmission’s rear output (coupling)
shaft to the vehicles differential. Failure to do so may
result in damage from lack of lubrication.
