The available servicing manuals are listed below. Truck-specific operations manuals are available, based on the design configuration of the vehicle, and typically include information such as: record of construction, warranty information, safety operations, pump operation and troubleshooting, foam system, care and maintenance of vehicle exterior, maintenance and lubrication, electrical diagrams, component literature, and certifications, weight slips, and parts list.
Please contact our Parts + Service Department with any manual requests or questions.
DRAIN THE PUMP
PROCEDURE TO DRAIN THE PUMP
After using the pump, drain in the following manner:
THIS IS CRITICAL IN FREEZING WEATHER!
- Open discharge valves and overboard suction valves, remove suction valve caps and discharge valve caps.
- Open pump body drain cocks, petcocks and master drain valves.
- On two stage pumps, move transfer valve to both the volume and pressure positions.
NOTE: If the pump is equipped with a power transfer valve, open the drain valves so that the pilot valve and actuating piston with drain.
- After the pump is completely drained, all the caps should be replaced and the valves put in the half open position.
ENGAGE + DISENGAGE THE PTO
PROCEDURE TO ENGAGE AND DISENGAGE THE FIRE PUMP, AND TO PUMP + ROLL
- Position the apparatus.
- Bring vehicle to a complete stop.
- Set the parking brake; be sure it engages.
- Leave the engine speed at idle.
- Place the transmission in neutral.
- Shift the Pump
- Engage the pump by pulling on the toggle switch labeled “ENGAGED/DISENGAGED” and then move it upward.
- The “PUMP ENGAGED” light will illuminate.
- “OK TO PUMP” light will illuminate.
NOTE: If the “OK TO PUMP” light fails to illuminate… Review to be sure parking brake is set and the transmission is in neutral. Move the “PTO” lever back to the “OUT” position. Start again at #2.
- Decrease engine speed to idle.
- Shift out of pump by pulling out on the toggle switch and moving it downward.
- The “PUMP ENGAGED” light will go out.
- The “OK TO PUMP” light will go out.
- Prepare for PUMP engagement by bring ENGINE speed to less than 900 RPM.
- Engage the Pump
- Engage the pump by pulling on the toggle switch labeled ENGAGED/DISENGAGED and then move it upward.
- The PUMP ENGAGED light will illuminate.
- OK TO PUMP & ROLL light will illuminate.
PRIMING THE PUMP
PROCEDURE TO PRIME THE PUMP
- Close all drain valves and discharge valve controls.
- Establish the connections to the water source, be sure all connections are tight.
- Engage the pump. To avoid damage to the pump’s seal, keep the engine speed at idle and do not allow the pump to run longer than 45 seconds without achieving prime.
- At the control panel, pull out the primer control knob to start priming. Operate priming pump until it emits a solid stream of water through its discharge pipe. When pump is primed, release the primer valve control.
- Adjust throttle control to accelerate engine to desired pump pressure.
PROCEDURE TO WINTERIZE YOUR APPARATUS
- Park apparatus on level ground, preferably over a large floor or storm drain.
- Take the drain cap screw out from below the water tank using a pipe wrench, channel lock, or similar tool. Take the drain cap off slowly to avoid damage to cap or tank.
- Allow the tank to drain completely.
- Remove old thread tape off the drain cap. Apply a new layer of thread tape around the middle section of the threads.
- Screw the drain cap back on slowly, do not over or under tighten.
NOTE: An alternative method to draining the water tank is the use of R.V. antifreeze to prevent the water within the tank from freezing.
The amount of antifreeze needed is dependent upon the type of antifreeze used and the amount of water that remains within the tank.
- Remove caps.
- Open all valves and petcocks.
- Drain pump using master drain.
- Drain and remove strainer.
- Drain pluming.
- Run primer until unit is drained; avoid running primer for longer than 30 seconds at a time.
- Leave all valves halfway open.
- Replace caps loosely.
- For either gasoline or diesel motors, ensure the tank is 1/4 of the way full.
- Read the manufactures recommendations to calculate how much fuel stabilizer you will need.
- Put fuel stabilizer into the fuel tank.
- Run the auxiliary pump for 5 minutes to ensure the entire fuel system is treated.
NOTE: Boise Mobile Equipment recommends the use of fuel stabilizer for auxiliary engines being stored over long periods without use.
NOTE: Follow all manufacturer recommendations for specific foam unit.
- Empty out old foam annually from foam tank.
- Using the foam system bypass line, flush all excess foam out with water.
- Use R.V. antifreeze in foam tank. Run pump in simulated flow mode and inject antifreeze into the system for 20-30 seconds.
4. Purge system with air while running the foam pump.
