5. Connect discharge hose, nozzles, etc.,
to pump, and
tighten firmly with coupling wrench.
6. Start the engine.
a. Open fuel valve.

c. Increase throttle past the idle position.
d. Position the ignition switch to the ON position.
e. Close all discharge and recirculation valves.
f.
Give starter rope a quick and steady pull until engine
starts.
g. Open/disengage choke.
h. Slightly open the recirculation valve. Water should be
recirculating back into the tank. If there is no water
recirculating, the pump has not been fully primed.
Re-prime the pump.
i.
Allow the engine to warm up for at least 2 minutes
before using full throttle.
7. Discharge water.
Once the pump is primed, and with the engine running,
you can begin to discharge water.
a. Slowly open the discharge valve.
•
To use the hose reel, slowly open the Reel valve
and close the Overboard discharge and
Recirculation valves.
•
To use the overboard discharge, slowly open the
Overboard discharge valve and close the Reel
and Recirculation valves.
b. Adjust the pump performance by throttling the engine
up or down, or opening or closing discharge valve at
various positions, or any combination of the two.
!
DO NOT
leave the pump running with all the
discharge valves closed for more than one minute,
or else the pump may overheat and become
damaged. To avoid this, open the recirculation valve
to allow fresh water to continue to enter the pump.
!
DO NOT
open the recirculation valve if the foam
eductor is in function to avoid pumping foam in the
tank. If this occurs, it is recommended to flush out
the tank with fresh water.
8. Apply foam (if applicable, and if equipped with the
optional Scotty Around the Pump foam eductor).
a. Ensure that the recirculation valve is
closed
when
using foam.
b. Open the Scotty foam eductor valve to the desired
eduction ratio.
c. Select the water discharge method. You can either
discharge water through the hose reel or through the
discharge valve.
d. When you are done using the foam, be sure to flush
the system thoroughly for at least 2 minutes. To flush
the Scotty foam eductor, close the eductor valve and
circulate fresh water through the eductor.
