• Place the battery in a holder with a flat base.
Ensure the battery cannot tip or fall over;
• Connect the positive lead to the positive terminal
on the starter solenoid;
• Connect the negative lead to an engine mounting
bolt, frame bolt or other good engine ground
connection;
• When connecting the leads to the battery, connect
the positive lead to the positive post FIRST;
• Tighten the connector firmly. Grease smeared
over the battery terminals will help prevent
corrosion;
• Connect the negative lead to the negative
battery post.
4.6 GX390UT2 regulator/rectifier
fitting instructions
Some new GX390UT2 engines now come with
several optional parts to enable you to adapt your
engine to better suit your application.
When a battery is fitted, to start the engine, the
regulator/rectifier is required to charge the battery
while the engine is running. The Wiring Harness
is required to connect the regulator/rectifier to the
engine. The wiring harness is designed so it can
only be connected to the engine one way. The wiring
harness has a 6-pin connector, a 2-pin connector and
two single wires, one Black and one White. The 6-pin
connector plugs directly into the Regulator/Rectifier
- Ensure that it “clicks” into the retaining clip. The
2-pin connector plugs into the white, 2-pin plug on the
engine. Again, ensure that it “clicks” into the retaining
clip. The black wire plugs into the black wire on the
engine. The white wire plugs into the white wire on
the engine. Make sure to push them in firmly.
IMPORTANT NOTES
The regulator/rectifier will get hot during operation,
so avoid placing it anywhere where it may represent
a burn or fire hazard. The regulator/rectifier requires
a good “Earth” connection, so remove any paint, or
surface treatment under the mounting points before
bolting it on. The regulator/rectifier may be adversely
affected by vibration, so it should not be attached to
the Firefighter. Attach it to the Roll Frame, or similar.

contact your nearest Authorised Honda Dealer.

4.8 Bare shaft models
Power requirements
Davey bare shaft models are designed to be
direct coupled to an electric motor or engine, or
can be belt driven. Some power losses will occur
through the coupling or belts and pulleys, and
these losses should be taken into account when
choosing the prime mover to power your pump.
The greatest power is required when the pump is
pumping the greatest volume of water. The power
output of the prime mover should be 15% more
than the maximum required by the pump for the
speed selected (refer to published performance
curves). This 15% extra power is to allow for power
transmission losses, less chance of overloading,
and wear and tear over years of operation.
Mounting of pump to prime mover
The pump and motor or engine should be mounted
on a substantial common base which is non-flexible.
Some adjustment should be possible to the position
of the pump in relation to the prime mover for
alignment purposes.
Direct coupling
It is essential for direct coupling a pump and motor
(or engine) that the two drive shafts be exactly
aligned. It may be necessary to pack under the feet
of either pump or motor. Do not have the two shafts
touching; minimum clearance of 2mm must be
provided. A two-piece coupling with resilient joiner
drive is recommended. The use of a rigid sleeve
type coupling is not desirable.
Belt and pulley driving
The use of slide rails to mount the motor allows easy
adjustment of the belt tensions. Pump speed greater
than the motor is possible by sizing the pulley fitted
to the pump smaller than that on the motor. In any
case pump speed must not exceed 4250rpm. A
double A section pulley drive is recommended.
Overtightening of belts will result in bearing failure at
the pump or motor.
