Insufficient Pump
Capacity, Single
Stage.
Insufficient engine
power.
• Engine power check and tune up may be required for peak engine
and pump performance.
• Also see heading “Rotation Symptoms.” on page 101.
• Recheck pumping procedure for recommended transmission gear
or range. Use mechanical speed counter on pump panel to check
actual speed against possible clutch or transmission slippage or
inaccurate tachometer.
• Check truck manual for proper speed counter ratio.
Relief valve improp-
erly set - if so
equipped.
• If relief valve pressure is set too low it allows the valve to open
and bypass water.
• Reset the relief valve pressure accordingly.
• See Section 4 Preventive Maintenance, heading “Relief Valve and
TPM Test” on page 73.
Suction hose diame-
ter is too small for the
volume being dis-
charged
• Use larger sustain hose.
• Shorten total length by remove one length at a time.
• Reduce volume of discharge.
Restriction in suction
line at strainer
• Remove any debris restricting entrance of water at the strainer.
• See Section 4 Preventive Maintenance, heading “Intake Strain-
ers” on page 75.
Air leaks
• See heading “Air leaks” under condition “ Pump Loses Prime or
Partial collapse of the
lining in the suction
hose
• Damage to the outer lining may allow air between the outer and
inner linings causing a partial collapse.
• Replace hose and retest.
Engine governor set
incorrectly.
• If the engine governor is set too LOW (pressure), when on auto-
matic, engine speed decelerates before the desired pressure is
achieved.
• Reset governor per manufacturer’s procedures.
Truck transmission in
wrong gear or clutch is
slipping.
• Recheck the pumping procedures for the recommended transmis-
sion or gear range. Also see Section 3 Operation, heading “Basic
Operation” on page 53.
• Use a mechanical speed counter on the pump panel to check
speed against possible clutch or transmission slippage or inaccu-
rate tachometer.
• Check truck manual for proper speed counter ration.
