I.Product Technical Specification
Airport LPG cannon Bird repellent
Model: HZQ-1090

1. Time control: time switch machine, fixed 2 minutes firing or 2-8 minutes random
firing mode;
2. The main body of the fuselage is reinforced design to improve the durability of the
whole machine;
3. Circuit system: the use of industrial-grade single-chip, integrated circuit module
design, good stability;
4. The cannon has good wind, rain, antifreeze and corrosion resistance, external
protection capacity IP34; can work in -15 ° C - +55 ° C , relative environment
humidity 95%.
5.Explosive sound level: ≥120db
6.Effective radius: ≥200m
working principle:
The system is controlled by a power supply system. The bird-driven cannon is
controlled by a single-chip computer control system to charge the combustible gas
and air into the combustion chamber to ensure that the combustible gas and air are
fully mixed. The high-pressure ignition system is controlled to ignite, the gas is
burned and expanded, and the gun is produced through the barrel. Beep the sound,
thus achieving the purpose of repelling birds.

III.Attention
(1) The gas gun should be placed firmly above the ground surface to ensure that it does
not accumulate water at its location. It is absolutely forbidden to soak the gas gun body in
the water. In case of heavy rain or long periods of rain and snow, Recover the equipment
in time and store it in a safe place to avoid damage to the equipment.
(2) When the battery is used out, Please charge for it timely. The battery is 12V/48Ah.
(3) Check the tightening degree of all installed parts regularly every month, and check
whether the high-voltage ignition head and connecting wires are loose.
(4) When replacing batteries or other parts, be careful not to reverse the polarity.
(5) In case of abnormal weather such as hail and squally winds, protective measures
should be taken immediately to collect the equipment into the warehouse.
(6) When replacing the gas tank and releasing the residual liquid of the gas inlet pipe,
ensure that the interface between the medium pressure regulator valve and the gas port

and quick-connect assembly is clean and clean, so as to avoid damage caused by other
impurities.
(7) The gas intake pipe is designed as a two-body structure, which is connected by the
quick-connect assembly. It is convenient to check whether there is gas residual liquid in
the intake pipe, and open the quick-connect assembly to release the gas residual liquid.
This inspection is once a week to avoid gas residue. The liquid flows into the combustion
chamber, causing a fire.
(8) In any case, it is absolutely forbidden to block the gun and place other objects in the
barrel. When using it, the barrel is prohibited from standing within 30 meters.
(9) If abnormal conditions are found, they should be inspected and repaired immediately.
(10) In order to use the device safely , please read the instruction manual and “Daily
Maintenance and Troubleshooting Methods for Bird Cannon”. If you have any questions
about this product, please contact us.
IV. Daily Maintenance and Troubleshooting Methods
for Bird Repellent
Since the gas gun is in working condition for a long time outdoors, it needs regular
maintenance , usually once a week. Every maintenance includes:
Check if the gas is normal and if there is any air leakage. But never use an open
flame or other source of ignition to check for gas leaks.
Check whether the structure of the gas gun is loose. In particular, the ignition head
behind the barrel is directly affected by the gas explosion. Therefore, pay special attention
to the inspection every time when you maintain it. If there is loose screw or loose nut,
tighten it with a tool.
Open the circuit board sealed box and press any time adjustment button to observe
whether the time is displayed. If the time display is normal, the power supply works
normally. If there is no display, there may be two problems.
Check whether the power supply is normal, such as the battery voltage is normal, and
then check whether the positive and negative poles of the power supply are reversed.
If the above problems are normal, it can be judged that the board has failed.
If the time is normal, the power supply is working properly. Press the gas gun test
button (see picture) to see if there is any sound of air intake or ignition.
If the peripheral device is installed properly, if there is no sound, it indicates that the
board is faulty.
If there is air intake and fire, but the sound of the air is very small, it means that the
gas is blocked. Please clean or replace the air inlet.
If there is no sound of the air intake, replace the high voltage igniter. If there is no
ignition after replacing the high voltage igniter, the board is faulty.

If there is no sound from the fire, replace the solenoid valve. If there is still no air
intake sound after replacing the solenoid valve, the circuit board is faulty.The most
problematic in the actual work of the gas gun is that the gas gun inlet nozzle is blocked.
Because impurities in the gas (such as condensate, tar, etc.), these impurities will
accumulate the moving parts, it is necessary to clean regularly to keep the equipment
working properly. Otherwise, the inlet nozzle may be stuck by the oily substance in the
cylinder, which affects the flow and mixing ratio control, which affects the gas gun
sounding effect.Liquefied petroleum gas will cause rubber and some plastics to age. Use
hoses specially designed for LPG. The hose should not exceed 2 meters. The hoses
should be equipped at both ends. The hose should be replaced every six months to
prevent aging and update Pressure valve once a year.
In the winter, attention should also be paid to the heat preservation treatment of gas
cylinders, pressure reducing valves, hoses and other components to prevent gas
condensation and freezing from reducing the gasification of liquefied petroleum gas and
affecting the normal operation of the gas gun.
In summer, due to the excessive external temperature, the gas volume of the gas
tank should be strictly controlled. The maximum amount should not exceed two-thirds of
the total storage gas to avoid danger.
After a long period of use, impurities in liquefied petroleum gas (such as condensate,
tar, etc.), especially when the gas volume in the liquefied gas tank is less than one-third,
will accumulate in the moving parts and the combustion chamber wall. In the above, when
the gas cannon is working, it is very likely to ignite it, causing unsafe factors and damage
to the gas cannon. The following points are emphasized here:
1. In summer, the amount of liquefied gas should be between one-third and
two-thirds; in winter, it should be kept at one-third to full.
2, regularly wipe the burning warehouse wall every month. That is, open the
high-pressure ignition head behind the combustion chamber, and wipe the wall with cotton
yarn. Note that cotton yarn and so on are not allowed to remain in the combustion
chamber.
3. When using for one year, it should be cleaned by a professional.
4. When using, the operator should pay attention to observe whether the
combustion chamber and other components are ignited, find them in time, and reflect and
solve them in time.
