3. Installation Method
3.1 Install the hybrid system to the appropriate position of UAV. The damping pad is
connected with the aircraft mounting mount, as shown in Figure 5 below：
Fig. 5
Caution ：The factory default is hoisting, other installation methods will cause shock
vibration damper damage
3.2 Cooling system installation and water pipe connection is shown in Figure 6 below：
3.2.1 Install the fixed water-cooling radiator.
3.2.2 Installation of fixed water jacket: the water jacket must be placed at the highest point
of the cooling system.
3.2.3 Installation of fixed water pump.
3.2.4 Connect the water pipe.
Water pipe of ①：Ø8 * Ø12；
Water pipe of ②：Ø12 * Ø16；
The red arrow marks the direction
of the coolant circulation flow, and the
distribution clamp is used at the end of

3.2.6 Precautions for use of coolant
a) Unscrew radiator cap,
b) Slowly fill the coolant into the water jacket. Be careful not to let the water bubble.
c) After supplying coolant, tighten the water jacket cap.
d) Check the connector of the cooling water rubber hose for looseness, damage or other
faults. If the sealing performance of the water pipe is poor, the cooling water may be consumed
excessively.
The radiator shall be installed under the propeller. If it is installed in other positions, the
forced air cooling fan shall be added, and the fan power supplied by ECU shall be less than
100W.
3.3 The oil pump installation and oil pipe connection are shown in Figure 7 below：
3.4 Operation method of engine fuel pipe exhaust
When the engine is started for the first time or the oil return pipe is not filled with oil,
exhaust treatment shall be carried out before starting the engine. The specific operation
methods are as follows: connect the gasoline bubble in series at the end of the oil return pipe,
press it several times to exhaust the air in the pipe, so that the fuel fills the whole oil supply
pipeline. At this time, remove the oil bubble and start the engine normally.
4. Preparation method of gasoline and lubricating oil
Use 95# or higher grade gasoline, Jaso FC grade or iso-l-egc grade or higher 2T engine
oil (Mott 710 is recommended), and use a proportioning pot to prepare according to the engine
fuel ratio of 1:40 (engine oil: gasoline). It is strictly prohibited to use vehicle 4-stroke engine oil.

The specific preparation steps are shown in Figure 8 below.
5. Inspection items before use
5.1 Check whether the connectors of the range extender and controller are connected
and installed in place.
5.2 Make sure there is enough fuel in the fuel tank and the fuel pipe is installed correctly.
5.3 Spark plugs shall be checked before use. Spark plugs with excessive carbon and oil
stains shall be replaced or cleaned.
5.4 Check the steering gear mechanism, check whether the steering gear rod ball head
is flexible, and repair it if it is stuck.
5.5 Check the position of steering gear and throttle, and check whether the steering gear
operates normally and whether the throttle position is correct.
5.6 Check the motor to see if it rotates normally.
5.7 Check the oil pipe. The oil pipe shall not directly contact with heat sources such as
engine or motor. Meanwhile, excessive bending of oil pipe shall be avoided.
5.8 The ignition coil head should be pressed firmly to check whether the connector is
loose.
5.9 There is no obvious bubble in the tubing.
5.10 Check the anti loosening mark of the connecting bolt, and there shall be no
dislocation.
Check whether the exhaust funnel is loose. In case of shaking, be sure to tighten the
fixing bolts of the exhaust funnel.
6. Precautions for starting engine
6.1 Before starting the engine for the first time, the air in the oil inlet pipe needs to be

higher gasoline to
the marking line
② Add lubricating oil
to the marking line
③ Mix the fuel in the inverted
proportional barrel.

discharged to make the oil inlet pipe full of oil and free of bubbles；
6.2 For the first using, the generator should be power on before adding coolant. After
power on, the electrical water pump will continue to run for about 100s. If the water jacket
is not full within 100s, the generator shall be re-powered on. Repeat until the air in the pipe
line is drained. The pipe lines can be squeezed properly until there is no obvious bubble
up welling in the water jacket; Generally, this operation is not needed during subsequent
startup, just observe the liquid level of water jacket, and add coolant when it is too low.
6.3 After each power on, the steering gear will execute the self-learning program for
about 8s. Operate the remote control to make the system indicator light normally on (the
remote control needs to be unlocked).
6.4 The engine must be idle for 30 seconds after starting, so that the crankshaft, piston
and connecting rod can be more fully lubricated.
6.5 Multiple start failures may cause the spark plug to be flooded. In this case, replace or
dry the spark plug and try to start again.

8. Running
8.1 System controller receiver signal pulse width definition：
1) Receiver transmission pulse width,
1.1ms (reserved), 1.5ms (start) and 1.9ms (shutdown),
with a cycle of 20ms；
2) The remote controller is equipped with a three
position switch (1.1ms is idle and not used).
8.2 To start the Halo-6000, please first confirm whether the three position switch of the
remote control is normal；
8.3 Turn the three position control switch of the remote control to the "bid winning" (as
shown in Figure 9) position for operation,
Observe the bus voltage, ensure that the drone voltage is stable at 57V ±
2V；
8.4 Observe the drone voltage and operate stably for about one minute to warm up the
engine；
Fig. 9
Superscript：
1.1ms reserved
subscript：
1.9ms stop
Middlescript
1.5ms start
1. Start or idle：
First, turn the three position switch of the remote control to
the "superscript" position, then turn it from the "superscript"
position to the "subscript" position, pause for 2 seconds, and
then turn the three position switch of the remote control to the
"bid winning" position to start the range extender (if it is not
started, repeat the above methods).
2. Power generation operation：
After the engine is ignited and idling, the range extender does not need any manual operation, and the
system automatically enters the power generation state.
3. Stop Running：
When the range extender is in operation, turn the three position switch of the remote control from the
"bid winning" position to the "subscript" position to stop, and the system will stop automatically.

8.5 In case of maneuver or gust during flight, the bus voltage will drop, which is a normal
phenomenon.
If the drone voltage drops rapidly and continuously and is lower than 53V, special attention
shall be paid, and it shall be immediately lowered for maintenance if necessary;
8.6 Running out of fuel will cause serious damage to Halo-6000r. Optionally, use the oil
level sensor to monitor the remaining fuel to ensure that the operation is stopped before
running out of fuel.
9. Stop Running
9.1 After continuous flight, Halo-6000 needs to be cooled. Therefore, after landing,
maintain idle speed for 30s. After the engine is shut down, do not turn off the power supply
and keep the water pump running for 3min.
9.2 After the booster runs, some parts are at high temperature. After the booster
stops running, please do not touch the booster to avoid scalding.
Gasoline is a volatile flammable and explosive liquid. At the end of the
day or during long-distance transportation.The remaining fuel in the
oil tank shall be drained and properly stored in the oil drum to avoid
danger!

Maintenance
Maintenance
1. For routine maintenance items (after each operation), the warranty will not be given if
the maintenance manual is not followed
1.1 Check whether the plug of the controller circuit is in good contact, and check
whether the oil pipe and water pipe are loose or leaking.
1.2 Check if the controller is damp and keep it dry.
1.3 Check the motor for dirt and moisture, remove dirt and keep it clean and dry.
1.4 Check the air filter, remove the dirt, and keep clean（to prevent foreign matters or
dust from entering the engine inlet）.
1.5 Check whether the fixing bolts are loose, and no loose bolts are allowed.
1.6 Check whether the steering gear rod ball is stuck. If it is stuck, oil can be applied
temporarily and replaced later.
2. Regular Maintenance(Carry out regular maintenance and parts replacement according
to Appendix 3)
2.1 After the Halo-6000 runs for 50h, check the carbon deposit on the spark plug. If the
carbon deposit is serious, remove the carbon deposit or replace the spark plug.
