Injector Nozzle’s Warranty Conditions and Instructions

• It is necessary to provide pictures, videos, or test reports detected by the injector nozzle inspection equipment when the injector nozzleis abnormal during use as evidence to feed back to the salesman.
• Abnormal conditions are properly explained such as：Smoke, 2. Engine shake, 3. Difficulty starting the engine, 4. Engine noise, 5. oil leakage etc.
• Injector Nozzle Warranty Coverage

After receiving the injector nozzle DSLA144P890+ within 15 days, if there is a performance failure and the product has no appearance damage, you can choose to replace it or repair it;

If the injector nozzle DSLA144P890+ has performance problems during the warranty period (6-12 months), and it is confirmed to be product’s problems after being tested, you can contact our salesmen to replace the same model or a reworked product with the same performance for free;

• If the injector nozzle has obvious scratches on the surface, it can only be repaired and it will be returned as it is if the product is confirmed to be fault-free.

• Injector Nozzle Out of Warranty Coverage

The injector nozzle’s warranty period has expired.

• Injector nozzle failure caused by high temperature, high pressure, humidity, rain and snow, saline-alkali land, earthquake, and used in abnormal environment.
• Injector nozzle damage caused by man-made reasons (throwing, strong magnetic field magnetization, set fire).
• Injector nozzle failure or injector damage caused by non-injector design, technology, manufacturing, quality and other issues.
• Injector nozzle failure due to system pressure exceeding system approved pressure.
• Injector nozzle failure caused by system voltage exceeding approved voltage.
• Injector nozzle failure caused by impurities (water, lead, aluminum powder, iron powder, sulfide) in the system fuel exceeding the standard requirements.
• Injector nozzle failure caused by not installing according to the tightening torque specified in the vehicle engine maintenance manual (the tightening torque is too large or too small).
• Injector nozzle failure caused by not following the installation angle specified in the injector maintenance manual.

1.8.  Injector Nozzle DSLA144P890+ Causes of Damage 

• Fuel injector nozzle failure caused by impurities (water, lead, aluminum powder, iron powder, sulfide) in fuel exceeding standard requirements.
• The nozzle is normally worn due to long time working under high temperature
• Nozzle needle wear leads to oil hole blockage, insufficient fuel injection injector cannot work properly.
• Nozzle needle wear leads to oil hole blockage, insufficient fuel injection injector can’t work properly.
• The wear of the nozzle leads to the increase of fuel quantity, resulting in black smoke of the vehicle, and the fuel injector can’t work properly when it is serious.
• If the nozzle needle can’t move smoothly stuck may cause serious damage to the injector nozzle
• The rusting of the nozzle spring leads to spring fracture and black smoke from the vehicle.
• The opening pressure of the nozzle decreases, and the oil quantity of the injector increases, leading to black smoke of the vehicle, and the injector can’t work properly when it is serious.
• Oil-nozzle needle valve lift adjustment gasket wear oil-nozzle needle valve stroke becomes larger, the fuel injector oil quantity becomes larger, resulting in black smoke of vehicles, resulting in the fuel injector can’t work properly when serious.

The cracking of the nozzle cap is caused by high intensity work under high temperature.

1.9. Injector Nozzle DSLA144P890+ Storage Standard

• Choose a suitable storage place

The warehouse and cargo yard where the injector nozzles are stored should be kept clean and dry, and away from the factory buildings that generate harmful gases and dust; do not mix with acid, alkali, salt and other substances; the storage place should have a good drainage system; the cargo yard should be flattened with gravel or furnace ash etc. to enhance the water permeability of the surface layer to keep the reservoir area dry.

• Strict requirements of warehousing

Strict inspections should be carried out when the injector nozzles are put into storage, the surface cleaning work should be done well to remove water traces, oil stains, ash and other dirt, remove the rust and do anti-rust treatment in time. Packaged nozzles must be protected from damage.

• Keep the warehouse dry and preventing moisture

The relative humidity is usually below 70% for the injector nozzles placed in the room, and the

corrosion of the injector nozzles is significantly reduced.

Injector nozzles must be stored in the warehouse, and they are forbidden to store in the same

warehouse with commodities with high water content.

• Stack Properly

After the injector nozzle is exposed to rain, the corrosion rate will increase significantly. The purpose of sealing is to isolate the injector from rainwater and humid air, so the warehouse window should be checked in time to avoid rainwater entering the warehouse.

If the injector nozzle package is damaged, it should be repaired or replaced; when the package is damp, the packaging material should be dried; if the original anti-corrosion and oil applied at the factory is found to be damaged or dried up, it should be cleaned and re-applied oil in time.

It is forbidden to leave the injector nozzle exposed in the air for a long time.

It is forbidden to store acid, alkali, salt and other substances together with the injector nozzle.

The unpacked diesel injector nozzle must be rust-proof during secondary storage.
