4. Орнотуу жана орнотуу
Маанилүү: Professional installation is recommended. Improper installation can lead to vehicle damage or personal injury. Always refer to your vehicle's service manual for specific removal and installation procedures.
- Биринчи коопсуздук: Ensure the vehicle is securely supported on jack stands on a level surface. Disconnect the battery if working near electrical components.
- Эски шокту алып салуу: Carefully remove the existing shock absorber according to your vehicle manufacturer's instructions. This typically involves unbolting the upper and lower mounting points.
- Орнотуу чекиттерин текшерүү: Clean and inspect all mounting points for damage, wear, or corrosion. Replace any worn components.
- Prepare New Shock: If applicable, install any necessary bushings or sleeves onto the QA1 DS403 shock absorber. Ensure all components are correctly oriented.
- Жаңы Шокту орнотуу: Position the QA1 DS403 shock absorber into the mounting locations. Secure the upper and lower mounting bolts, but do not fully tighten them until the vehicle is at ride height.
- Акыркы бекемдөө: Once the vehicle is on the ground and at its normal ride height, fully tighten all mounting bolts to the vehicle manufacturer's specified torque values.
- Тазалоону текшерүү: Verify that the shock absorber has adequate clearance from all suspension and chassis components throughout its full range of motion.

5. Иштетүү жана жөндөө
The QA1 DS403 is a single adjustable shock absorber, meaning it allows for adjustment of both compression and rebound damping simultaneously with a single knob or dial. This adjustment affects the overall stiffness of the shock's resistance to movement.
5.1 Жөнгө салуу процедурасы
- Locate Adjustment Knob: The adjustment knob is typically located at the bottom or top of the shock body.
- Understand Clicks: The adjustment mechanism usually operates in "clicks." Turning the knob will increase or decrease damping. Refer to QA1's specific documentation for the total number of clicks and their effect.
- Баштапкы жөндөө: Start with a recommended baseline setting (often provided by QA1 or found in performance guides). A common starting point might be midway through the adjustment range.
- тууралоо Дamping:
- Turning the knob clockwise generally increases damping (firmer ride).
- Turning the knob counter-clockwise generally decreases damping (softer ride).
- Test and Refine: After making adjustments, test the vehicle in a safe environment. Make small, incremental changes and note the effect on ride quality and handling. Adjust all shocks equally for balanced performance.
Эскертүү: Always adjust shocks in pairs (front or rear) to maintain vehicle balance. Consult QA1's official resources for detailed adjustment guidelines specific to your application.
6. Техникалык тейлөө
Regular maintenance ensures the longevity and consistent performance of your QA1 DS403 shock absorbers.
- Үзгүлтүксүз текшерүү: Periodically inspect the shocks for signs of leaks, damage to the body or shaft, worn bushings, or loose mounting hardware.
- Тазалоо: Keep the shock bodies clean, especially the threaded sections and adjustment mechanisms, to prevent dirt and debris from affecting performance or causing wear. Use mild soap and water, then rinse thoroughly.
- Втулкалар: Check rubber or polyurethane bushings for cracks, hardening, or excessive wear. Replace them if necessary to prevent noise and maintain proper articulation.
- Монтаждоочу аппаратура: Verify that all mounting bolts are torqued to specification. Loose hardware can lead to noise, premature wear, and unsafe conditions.
- Shaft Protection: Ensure the shock shaft is free from nicks, scratches, or corrosion, as these can damage the internal seals and lead to fluid leaks.
7. Кыйынчылыктарды
This section addresses common issues you might encounter with your shock absorbers.
7.1 Жалпы маселелер жана чечимдер
- Excessive Bouncing or Poor Ride Quality:
- Себеби: Damping set too soft, worn internal components, or incorrect spring rate.
- Чечим: Көбөйтүү гamping (turn adjustment knob clockwise). Inspect for leaks or damage. Ensure correct spring rate for vehicle weight.
- Harsh Ride or Lack of Suspension Travel:
- Себеби: Damping set too stiff, incorrect spring rate, or shock bottoming out.
- Чечим: Decrease damping (turn adjustment knob counter-clockwise). Verify correct spring rate. Check for proper shock length for application.
- Noise (Clunking, Squeaking):
- Себеби: Бошотулган монтаждоочу жабдыктар, эскирген втулкалар же ички шоктон улам келип чыккан бузулуу.
- Чечим: Tighten all mounting bolts to specification. Inspect and replace worn bushings. If noise persists and no external cause is found, the shock may require professional inspection or replacement.
- Суюктуктун агуусу:
- Себеби: Damaged seals, bent shaft, or manufacturing defect.
- Чечим: A leaking shock absorber indicates internal damage and requires replacement. Do not attempt to repair.
If troubleshooting steps do not resolve the issue, contact QA1 customer support or a qualified automotive technician.
