1. Fire pump operation instruction
In order to extinguish the fire quickly, it is necessary to operate the fire pump exactly and masterly
1. CB10/60 operation instruction
a．Priming water：
   If using water from tank, we can push the butterfly valve toward to the fire pump shaft direction in order to pull the pin out from pin-hole. Then pull the handle to horizontal position and open the butterfly valve, after that, water will be flowing into the pump.
   If using water from hydrant, we can connect the suction pipe to the hydrant, and then the water will be flowing into the pump from the hydrant
If using water from pond, we need to use a piston primer pump for priming water. In this situation, firstly we can put the suction pipe into the pond; secondly start the low pressure fire pump; thirdly turn the pump rotational speed to 3200r/min in a short time; fourthly pull the control handle down and the piston primer pump begin to work. The water priming will be finished in 40 seconds, then the fire pump begin to work and the piston primer pump stop working automatically, after that ,we can push the control handle up to normal position, if the water priming are not finished in 60 seconds, please check whether there is air leakage in the system.

b．Low pressure work condition
   Open the ball valve which is in the low pressure outlet, and then turn the reflux ball valve to “low pressure” position.

(1) Water from hydrant
    A. After parking the vehicle according to correct steps, take out fire hose and hydrant wrench.    
B. Connect the outer injection joint to the hydrant with fire hose.
C. Open the hydrant valve with hydrant wrench until the tank has been full.

(2)Water from river and pond
A. After parking the vehicle according to correct steps, take out suction pipe, water-strainer and suction pipe wrench.
B. Connect the suction pipe to the inlet of the fire pump and make sure the length is suitable, then fix the water-strainer on the end of the suction pipe and put it into the river or pond (0.5m under water surface is best).

Notice:
1 Do not bend the suction pipe excessively.
2 Make sure the bending part not higher than the inlet of fire pump.
3 Do not make the water-strainer touch the bottom of pond or river to prevent sundries.
4 Make sure there is not air leakage at all joint, otherwise the water will not be primed
5 Turn off all valves, making the transmission in neutral. Start the engine, push the clutch, press the PTO switch, then release the clutch slowly until the fire pump runs.

        Open the pipe valve between tank and fire pump, start fire pump, turn the hand throttle to make the rotational speed to rated speed. When the value of vacuum gauge is from 50Kpa to 80Kpa, open the outlet valve, then turn the hand throttle to proper pressure.
(2) Priming operation (Supply from hydrant):
        a After parking the vehicle according to correct steps, take out fire hose, collecting breeching and hydrant wrench.    
        b Connect the outer injection joint to the hydrant with fire hose and collecting breeching
        c Open the hydrant valve with hydrant wrench, when the water has been primed into the pump, the following steps are same as water supplied by tank situation.
(3) Priming operation (Supply from river and pond):
        The operation steps are the same as water supplied by tank situation a to c.

3. Fire fighting
1). with water
After parking the vehicle according to correct steps, connect the fire hose and hose nozzle correctly, aim to the fire source, operate the clutch and PTO to make the pump start to work. Open vacuum gauge, pressure gauge and cooling system stopcock, check the indication of each gauge, and turn the hand throttle, when the pressure gauge indicates around 0.8Kpa to 1.0Kpa, open the outlet valve, then turn the hand throttle to proper pressure.
Note: Turn off the inlet valve while firefighting.

 2). with foam
 Water foam proportioner:
 Fitted on the fire pump, composed of water pipe system, ball valve, inlet pipe, adjust valve, Y-branch, outlet soft pipe.
Working principle:
When the water with pressure gets into the nozzle through the pressure pipe, cock, then out of the nozzle, negative pressure will be formed inside the proportioner. The foam liquid in the foam tank is sucked into the proportioner through the liquid pipe, ball valve, the calibration hole of the control valve, mixing with the water inside. After the injection pipe, outlet pipe, bending pipe to the pump, the mixing liquid is mixing in pump again and then being pressurized, most of the mixing liquid is sent to the injecting equipment to inject as foam, and small part of it enters the proportioner for running circularly.

Fire fighting with foam:
Two foam liquid supply:
1.    Supply from the foam tank: The foam liquid, sucked by the proportioner from the foam tank, is sent to the air-foam maker through the fire pump, forming the foam.
2.    Supply from the external foam source: the foam liquid is sucked from the foam liquid bucket through the inlet of the air-foam spear, making foam for fighting fire.
(1)    Foam liquid from the foam tank:
a.    Take the water hose and air-foam spear as needed.
Connect one end of the water hose with the fire pump outlet valve, and the other end is connected with the air-foam spear (other spraying equipment)  
b.    Make the handle of air-foam spear at the position for mixing liquid and water.
c.    Start the fire pump for water supply as the instruction.
d.    Turn on the switch of outlet valve.
e.    Open the throttle, adjusting the pump pressure till the standard working pressure of the praying equipment.
f.    Turn down the operation handle of foam liquid on the fire pump, open the foam liquid inlet valve on suction pipe, the air-foam liquid will spray out from the fire monitor (foam spear) or other spraying equipment.
g.    If the foam liquid in foam tank has run out, the foam inlet valve could be turned off. After wrenching the screw of the external liquid inlet, fit the pipette, and get the other end into the foam liquid bucket, the foam could continue praying.
h.    While the fire pump is send the mixing liquid, if the water in tank is not enough, don’t add any water with pressure at the inlet of fire pump.
i.    After fighting fire, the proportioner and the pipe system must be cleaned with water. The proper way is to put the pipette into clean water, start the pump, and turn on the proportioner valve.
(2)    Foam liquid suction:
a.     Take the water hose and air-foam spear as needed.
Connect one end of the water hose with the fire pump outlet valve, and the other end is connected with the air-foam spear (other spraying equipment)  
Make the handle of air-foam spear at the position for mixing liquid and water.
b.     As the instruction for fire pump in water supply, adjust the pump pressure, reaching the indicated outlet pressure of the air-foam spear, then the foam could be sprayed out.
c.     The air-foam spear must be cleaned after firefighting.
NOTES:
In both condition, the foam outlet valve should be turned off, preventing the water backflow to the foam tank


Ⅴ. Other fire equipment brief introduction

1．Monitor operation
Making sure the water in pump be with pressure after the operation above, the monitor aims at the fire scene and adjust its angle, then open the valve under the monitor.
The monitor could spurt like stream by adjusting the handle at the muzzle of monitor.

2．Fire hose reel and firefighting gun
     This series vehicle has been equipped with a set of fire hose reel and middle pressure
gun. Take out the middle pressure gun and pull out the fire hose to proper length. Open the reels input valve, make it aim to fire scene and pull the trigger. It can also spurt both fog and stream by adjusting the gun.

3．Siren
       This series vehicle has been equipped with multi-function electronic siren. Before using, turn on the main power switch, then turn on the siren power switch, finally turn on the relevant switch according to practical demands.
If the vehicle contains foam system, please acquaint yourself with the using of foam system, in order to operate skillfully.

 4．Foam proportioner
The foam proportioner is fixed on the fire pump, including pipeline from outlet pipeline, ball valve, refilling pipe, adjusting valve, Y tube and effusion tube.

Working principle:
    When the pressure water of pump flow into foam proportioner nozzle and spurt out by passing the pressure pipe and faucet, it will lead to a negative pressure. At this moment, the foam from the foam tank will be flow passing inlet pipe, ball valve, ration orifice of adjusting valve and then be sucked into mixing box automatically. After it is mixed with the water in mixing room, it will flow passing adjutage, outlet pipe and siphon into the water pump. Then the mixed liquor will be mixed again and pressurized in the pump, after that, most of the mixed liquor will be spurt out as foam, the rest flows into the proportioner for recycling.
When using, take the steps as follow: open the outer inlet cap of the foam tank, adjust the position of location hole according to foam spray equipment and flow, open the faucet and inlet pipe ball valve, adjust pump pressure according to foam spray equipment’s pressure, the proportioner provide mixed liquor according to stated ratio, at last, the mixed liquor is mixed with the inhalant air and form the final foam mixed liquor spraying to the fire scene to extinguish


Ⅵ. Attentions on Using

1. When using foam proportioner, the fire pump cannot suck pressure water from hydrant.
2. Make sure the clutch is detached completely and the engine speed is low when the PTO is approaching or departing.
3. Fire pump running without water for more than 3 minutes or at a high speed are not allowed.
4. When the system is running, before all the water outlet valves have been closed, it must reduce the pump speed. Fire pump running in over rated pressure for a long time is not allowed.
5.  After water priming finished, reset the priming handle.
6. After PTO working over 10 minutes in hot weather, it must turn on the water cooling stopcock, otherwise it may cause problems, the water must be drain out when the work is over.
7. If using seawater, sewage, corrosive liquid or foam, please run the fire pump with clear water to clean the fire pump .If using in cold weather, make the piston pump run for a while to drain out the remaining water to prevent it from freezing.
8. It is equipped with a breather valve on the top of foam tank. When using foam to extinguish fire, the foam liquid level will decline, the breather can suck air to make sure the ratio of water and foam are not change.
