Operation

• The suction hose should be set up and held,
  strainer away from the pump, and coupling end
  towards pump.

17
Operation

• Holding both ends of the hose, the coupling end
  level with the pump, lower the strainer end into
  the water and fill the hose with water.

18
Operation

• Lift the strainer end level with the pump.

19
Operation

• Connect the coupling end to the suction
  connection of the pump, keeping the strainer at
  the same level as the pump.

20
Operation

• Throttle
• Midway (shown for starting, - all the way to the
  left for operation

21
Operation

• Choke (white)
• Full to left (shown) for cold starting, - all the

24
Operation

• Pull on the starter cord until the pump starts.
• Lower the suction strainer into the water.

25
Operation

• Wait for 5 to 10 seconds and then close the choke
  and open the throttle to full for maximum pumping
  rate.

26
Operation

• The pump set up when pumping
• Throttle to the left
• Choke to the right
• Fuel open (full to the right)

27
Operation

• As soon as the pump is running, the end of the
  hose needs to be held before water comes out.
• The hose is set to jet for distance.

28
Operation

• The nozzle to water wall to provide heat
  protection to self and boat when closing in to
  pick persons off burning boats.

29
Operation

• When using the pump for de-watering, do not have
  a nozzle on the end of the hose to maximise the
  discharge rate.

30
Operation

• When pumping out a vessel, have the pump as low
  as possible, and the suction as low as possible
  to maximise the discharge.
• The noise of the pump in an enclosed space will
  be loud.
• The exhaust of the pump in an enclosed space will
  be dangerous.
• Blocks as many leaks as possible in the early
  stages.

31
