Operating Procedures
3-16
Stainless Max Series Pumps
❑
Consider the piping within the truck. Further suction losses may
result from additional suction piping added to the fire pump
during assembly by the manufacturer.
❑
Follow the maintenance and inspection procedures.
❑
Cavitation can occur with large nozzle tips. Solve this problem
by reducing flow.
❑
Cavitation can also occur when air enters the pump. The pump
may be primed, however, air leaks can cause rough operation
and an increase of engine speed without an increase in
pressure or flow. If an air leak is suspected, discontinue
pumping and refer to Section 5: Trobleshooting.
POST OPERATION PROCEDURE
1. Return the engine to idle.
2. Slowly close all valves.
3. Place the transmission in NEUTRAL or PARK.
4. Slowly shift from PUMP to ROAD to disengage the pump.
