QUICK GUIDE
To shut down and store the BB-4-D902 unit:
1. Shut down the pump.
a. Gradually reduce the engine speed.
b. Whenever the unit has been run at full throttle for most of the operation, allow the valves to remain slightly
open and run the engine at idle for approximately 5 minutes before shutting down the unit.
c. Turn off engine.
d. Close off the hydrant/supply to the pump.
e. Open all valves to relieve any pressure left in the system.
2. Check and store the pump.
a. If the pump was last run with foam or water that is salty, brackish or high in mineral content, flush the pump
with fresh water for a minimum of 2 minutes or until water is clear.
b. After the unit has cooled down, check all fluid levels and add as needed.
c. Completely drain the pump of all water.
d. Break down and store all equipment as outlined by the apparatus or department procedures.
e. Visually inspect the pump end. Clean any dirt or debris from the pump unit. If necessary, a mild soap and
water solution can be used. Note and report any performance irregularities or any abnormal mechanical
sounds.
f. Close all valves and plug all openings.
g. Follow any other product, component, apparatus, and departmental procedures and/or guidelines before
placing the unit in storage. Make sure all necessary tools, spares, and accessories are with the pump.
To operate the BB-4-D902 unit in cold weather:
The pump can be run in below freezing temperatures if certain precautions are taken to avoid the formation of
ice in the pump.
After priming the pump, the unit should be run at low speed for a short period of time to allow all components
to warm up before continuing with the remaining operating procedures.
Unless wrapped in a heater, drain the pump of all water if it is stopped for any length of time. The engine/drive
unit should be turned over a few revolutions to make sure all water has been removed from the pump. Drain
the pump priming line if a primer has been used.
After use, drain the pump, manifolds, and lines of all water. You can also pour some RV antifreeze into the
pump and circulate it through the pump and plumbing system.
