4. Configuración e conexión
Before operating the CP828H, ensure proper setup of your air supply system.
- Compresor de aire: Connect the air ratchet to a clean, dry air compressor capable of providing sufficient airflow (CFM) and pressure (PSI) for the tool's requirements. Refer to the specifications section for details.
- Mangueira de aire: Use an air hose with an appropriate diameter and length to minimize pressure drop.
- Air Filter/Lubricator/Regulator (FRL) Unit: Install an FRL unit in your air line. The filter removes moisture and debris, the lubricator provides essential oil for the tool's internal components, and the regulator controls the air pressure.
- Quick Connect Coupler: Attach a quick-connect coupler to the air inlet of the ratchet wrench.
- Configuración de presión: Set the air regulator to the recommended operating pressure (typically 90 PSI / 6.2 bar). Do not exceed the maximum pressure.

5. Instrucións de funcionamento
Follow these steps for safe and effective operation of your air ratchet wrench.
- Conectar o enchufe: Select the correct 1/2-inch drive socket for the fastener and firmly attach it to the anvil of the ratchet wrench.
- Control de dirección: Locate the direction switch (typically a small lever or knob near the ratchet head) and set it to the desired direction (forward for tightening, reverse for loosening).
- Ferramenta de posición: Coloque o encaixe perpendicularmente sobre o fixador.
- Activar o gatillo: Depress the trigger to activate the tool. The CP828H features a teasing throttle for precise speed control. Apply gradual pressure to the trigger to control the speed and torque output.
- Monitor de par: For critical applications, use a torque wrench to verify the final torque setting after using the air ratchet. The air ratchet is designed for fast removal and installation, not for precise final torque.
- Liberar o disparador: Solte o gatillo para deter a ferramenta.

- Limpeza: Keep the tool clean and free from dirt, dust, and debris. Wipe down the exterior with a clean cloth.
- Filtro de ar: Regularly check and clean or replace the air filter in your FRL unit to ensure a clean air supply to the tool.
- Hose and Couplings: Inspect air hoses and couplings for wear, damage, or leaks. Replace any damaged components immediately.
- Almacenamento: Store the tool in a dry, clean environment when not in use.
