Startup and Discharge
1. Fill fuel tank with recommended fuel grade.
a. For models with an integral fuel tank, fill tank and securely replace cap.
b. For models without an integral fuel tank, fill external fuel tank and connect fuel supply line to the
fuel filter. Pump fuel to fill supply line. For the diesel pump model, refer to the engine manual for
fuel system air bleeding instructions.
2. Start the engine.
For BB-4-18, BB-4-23, and BB-4-21:
a. With all discharge valves closed, turn the on/off ignition key or
switch to the “ON” position.
b. Open fuel valve.
c. Close/engage choke, if engine is cold.
d. Increase the throttle past the idle position.
e. Start the engine using the key switch or the start button. Hold
until engine starts. DO NOT HOLD for more than 5 seconds.
If starting using the rewind starter, ensure that the key switch or ignition switch is on the “ON”
position. Give starter rope a quick and steady pull until engine starts.
f. Open/disengage choke
g. Allow engine to warm up for a minimum of 2 minutes before using full throttle.
For BB-4-D902 using the PMSCP-DIESEL control panel:
If equipped with a LOFA control panel, refer to LOFA’s Panel
Operation and Troubleshooting Guide for instructions.
a.
Push the control panel’s ON/OFF button. A green
ring on the
button will light up indicating that the panel is powered. You
can now use the electric primer if equipped (see Priming
section).
b.
Warm up: The electric starter’s glow plugs require a 10
-second
warm-up period which begins as soon as you push the
ON/OFF button on the control panel. During the warm-up
period, the START button is deactivated and the engine
cannot be started. As soon as the warm-up period is over, the
low oil pressure (
) light will turn on, indicating that the
engine is ready to start.
Important:
If low oil pressure light does not turn off after
engine has starter, stop the engine and check the oil level.
c. Make sure all discharge valves are closed.
d. Once the pump is primed, push and hold the START button until the engine starts.
e. Turn the Vernier throttle counter-clockwise to increase engine speed past the idle position.
Pressure should build up in the system.
f. Press the LOW PRESSURE PROTECTION button to activate the protection. If pressure drops
below 7 psi (loss of prime condition), the engine will automatically shut down to protect the pump.
Note:
Leaving the pump running with all the discharge valves closed is called
deadheading
the
pump. The pump should not be left in this mode for more than a minute. Leaving in this
condition for any length of time will cause the pump to overheat and damage the pump.
To avoid overheating the pump, a re-circulation line (if provided) should be opened or a
discharge line left slightly open to allow fresh water to continue to enter the pump.
