4. OPERATING PRECAUTIONSNOTEPlace the pump as near as possible to water source, and watersuction height as low as possible.
When lowering the portable fire pump to the ground, lower it gently
and horizontally.
Max. permissible inclination angle: 15°
In case of the inclined or uneven location, make sure that watersuction hose is lower than suction port of the pump.
In case of the suction hose is put undulated, air can be left easily inthe hose, and possibly causes suction inability when the water
discharge valve is opened. In this case, set the water discharge valve
half-opened, and operate vacuum pump until water is discharged
continuously (for 3 to 5 seconds from beginning of water discharge).
Be sure to install strainer and basket on the end of suction hose. If
the pump may suck sand or mud on the bottom of water source,
place sheet below the basket.
Put the strainer and basket of suction hose into the water more than
30 cm from the surface to prevent suck of air.
Discharge hose should be arranged not to be bent.

Closed discharge valves operation after priming water
When the pump is operated with the discharge valve closed, the cooling watertemperature becomes high.
When the cooling water temperature reaches 50°C or more, the thermostat opens
and allows the high temperature cooling water to be released outside through thepipe connected to the thermostat and simultaneously cooling water comes in fromthe water pump so that the cooling water temperature can be controlled. When thecooling water temperature goes down below 50°C, the thermostat closes to stopcooling water being released.
CAUTION

When performing the closed discharge valves operation
after priming water, adjust the throttle so that the pumppressure becomes greater than 1 bar.
If the pump is being operated with the pump pressure too low,
the pump may suck air in when the thermostat opens, andcannot keep water in the pump without suction operation.

32

9. PRIME AND DISCHARGE
While the engine is running with the cowl removed,
do not touch the rotating parts of the pulley orbelt. This may cause personal injuries.

NOTE

If the pump could not prime water in 30 seconds, or
could not suck up water continuously by the pumpduring the discharge operation, check the following :Is the tip of the suction hose completely below the water surface?
Is air sucked through the joint of the suction hose?
Is the suction hose damaged?
Does the vacuum performance of the priming pump reduced
significantly?
Does the pump case keep vacuum?(No air leak from the pumpcase.)
Does vacuum leak occur when the pump is connected to asuction hose of which the opening is capped?
Refer to “Chapter 16 TROUBLESHOOTING”.

9. PRIME AND DISCHARGE
Performing relayed water supply. (In the case of sucking water from a fire hydrant.)
1. Determine the pump pressure in consideration of the water discharge pressure(nozzle pressure), hose pressure (friction) loss, and height loss.
Pump pressure = needed pressure + friction loss + height loss
2. Foreign materials such as dirt, gravel, iron rust, etc. may have intruded into a fire
hydrant. Before connecting a hose, open a fire hydrant to discharge water in orderto remove foreign materials.
3. When sucking water from a fire hydrant, use a mediation metal to connect a delivery
hose to the suction port without using the suction hose in principle.
4. Set the discharge valve handle of the pump to the full open position.
5. Gradually open the fire hydrant on-off valve for the full open position.
However, check the water pressure from a fire hydrant with suction pressure gaugeof the pump and adjust the opening of fire hydrant, if necessary.
CAUTION

In the case of water pressure from fire hydrant is higher than 6bar, do not continue to open the fire hydrant on-off valve.

* In the case of water pressure from a fire hydrant is higher than the requireddischarge pressure, it is not necessary to start the pump. If the water pressure
from the fire hydrant has not reached the required pump pressure, start theengine.
6. If the water pressure from a fire hydrant is insufficient, start the engine and adjust
the pressure to the required level by operating the throttle dial.
Stop increasing discharge pressure of the pump if the suction pressure gauge shows
1bar or below. In this case, stop increasing the pressure and keep the throttle dial as
it is.
7. To end discharging water, turn the throttle dial to the low pressure firstly, then stopthe engine, and close the fire hydrant on-off valve.
CAUTIONBe sure not to close the discharge valves and nozzle(s) of pumps
until all the pumps stop and the fire hydrant on-off valve is closed.

Preparation for operations
Never close the discharge valve of source pump, the relaypump(s) and the fire nozzle(s). If the discharge valves or nozzle
is(are) closed, there will be a risk of damage to the pumps andhoses with excessive pressure or water hammer.
1. Decide how many relay pumps are needed in consideration of the distance andheight between the water sauce and the fire ground.
2. Place the pumps according to the decision, and then connect the hoses.
3. Make sure that the relay pump discharge valves are opened, including the firenozzle(s).
4. Decide the discharge pressure of each pump in consideration of needed pressure
for the next pump (or fire nozzle) and the friction loss and height loss.

Pump pressure = needed pressure + friction loss + height loss
Starting of Source Pump
Once the water supply has started, keep supplying it until finished. If
reducing or stopping water supply, overheat or cavitation may occur
in the relay pump(s).
1. Start the source pump according to “Chapter 8 STARTING THE ENGINE”.
2. Start supplying water according to “Chapter 9 PRIME AND DISCHARGE”.
Starting of Relay Pump
1. Make sure that the discharge valve is opened and wait for the water supplied.
2. Check that the water was supplied from the source pump. At first, the hose swells
due to air pressure. Step on a hose to judge whether the swelling of the hose is due
to water or air.
3. When the water is supplied to the pump, check the pressure of the gauge. Start theengine if the pressure is lower than the decided. If the pressure is higher than thedecided pressure, no need to start the engine.
4. Adjust the discharge pressure with the throttle dial. The suction pressure decreases
with throttle dial up(Increase discharge water). Always check it with a suction
pressure gauge.
5. If the suction pressure decreases below 1 bar, order the operator of the pre-stage
pump to increase the water pressure, and adjust the relay pump pressure by thethrottle.
6. If the suction pressure rises, adjust the water pressure by the throttle dial operation
again.
