Instruction Manual

For most efcient operation, site the pump as close to the water as practical.
It is essential for the correct function of the engine that it be located on a horizontal surface. If
allowed to run at an inclination, the oil lubrication system of the engine may not operate correctly.
Subsequent engine failure would not be covered by the manufacturer’s guarantee.
The pump should be positioned in a well drained location to avoid possible property damage by
leaking hose ttings or pump seals, spilled engine fuel etc.
If you intend to operate your pump on a hard surface, Davey suggest a suitable resilient
mounting to be tted to your pump and engine.

A reinforced or non-collapsible hose should be used for the pump suction. The minimum suction
pipe size should be 38mm (11/2”) I.D. for up to 6.5hp Fireghter
®
models, 50mm (2”) I.D. for
G5006 and 9hp & 13hp Fireghter
®
models and 80mm (3”) I.D. for G8016 Fireghter
®
models.
A strainer should always be tted to the bottom of the suction pipe. The strainer should be kept
out of sand, mud etc., to avoid particles being drawn into the pump and causing damage by
abrasion.
Always locate the pump so that the rise of suction pipe from water to pump is even with no
humps or hollows where air may be trapped.
All pipe connections must be air tight for best priming and operation - check that washers in nuts
and tails are in good order.

Care should be taken on correct selection of pipe pressure rating as single stage Fireghter
®
units are capable of delivering pressures up to 650kPa (93psi). Two stage Fireghter
®
Plus units
are capable of pressures up to 1135kPa (165psi).

The priming plug and drain plug both have “bayonet” style tment, with a safety release
mechanism. To insert the plug, ensure the handles on the plug are in line with the engine shaft or
pointing towards the engine for the priming plug (gure one) and vertical for the drain plug.

• Run the pump every week or so during the re season to ensure it and associated pipework
etc is in good working order. This will also help turnover the fuel and make sure the
lubricating oil is circulated around the engine.
• Ensure the water source is free of leaves and sticks etc which may be block inlet strainers
and obstruct the water ow to the pump.
• Check for pipe leaks and the correct operation of all valves connecting the pump to the
water source and to the discharges.
• Air leaks on the suction line are the number one cause of pump problems, make sure all
rubber gaskets and seals are in good order.

Your pump and pipework is an important part of re protection, but so are the other things you
must do to be ready.
Davey strongly encourage you to work through your re plan and make sure it’s able to work
under a realistic assessment of the worst possible situation. Fire only really understands the
worst possible situation.

These special models, identied by a black handle (when factory tted) or a sticker (when tted
in the eld), have been supplied with Viton
®
seals and elastomers. This is to provide the pump
with superior resistance to common agricultural chemicals. These pumps should still be ushed
out with clean water after use.

The fuel stop solenoid is an optional extra that is available on selected Yanmar diesel engines at
the time of purchase. Controlled via a key switch, it starts and stops the ow of fuel to the engine
to start and stop the Fireghter
®
pump. This allows the Fireghter
®
pump to be installed on a tray-
back vehicle and have the convenience of being controlled from inside the cabin of the vehicle.
The switch has three positions, off (O), ignition (I) and crank (II). In the ignition position, battery
power is supplied to the solenoid and the crank position starts the engine. To stop the engine,
turn the switch to the off position.

The pump unit should be drained of water and normal engine storage procedure should be
followed. (Run unit until fuel is exhausted, drain and ll sump with fresh oil). The unit should be
stored in a dry place. Before starting pump after storage it should be checked to make sure that
it is free to rotate by pulling Engine Starter with ignition off.

Pump impeller is screwed clockwise onto the engine shaft. The impeller assembly is xed
together by a setscrew and can be disassembled in two halves by removing the setscrew or the
entire impeller assembly can be removed.
To remove the entire impeller assembly, unscrew locking setscrew or impeller/s anti-clockwise
using a socket in eye of impeller. If difcult to remove, lock engine crankshaft at recoil starter end.
