Pump Priming and Operation
Priming Pump
NOTE
All pumps are primed in a similar fashion. PT4 is shown.
See Figure 2-2.
WARNING
When priming the pump, only use water.
Failure to comply may result in injury or death
to personnel.
WARNING
Do not prime pump for more than 5 minutes. If
pump priming is taking longer than 5 minutes,
turn off engine and allow pump to cool. Failure
to comply may result in injury or death to
personnel.
WARNING
High temperatures and/or pressures may be
caused during priming or operation. If high
temperatures and/or pressure conditions exist,
do not open any plugs or hoses. Failure to
comply may result in injury or death to
personnel.
WARNING
Ensure discharge hose is secure before
operating the pump. A loose discharge hose
may cause the hose to slip or become
detached. Failure to comply may result in injury
or death to personnel.
CAUTION
Inspect pump and associated accessories
before each use. Failure to comply may result
in damage to equipment.
CAUTION
inspect hoses to ensure they are the correct
diameter and free of damage. If the hose
diameter is to small or the hose is damaged, it
will cause the pump to cavitate. Failure to
comply may result in damage to equipment.
NOTE
To avoid air leaks and slow priming, ensure the suction
hose is connected properly.
