To properly use your Einhell CC-HS 12/2 Car Hammer Screwdriver for tightening wheel nuts, follow these steps:
- Power Connection: Plug the 12V power adapter into your vehicle's cigarette lighter socket.
- Direction Selection: Use the direction of rotation switch (located above the On/Off switch) to select the correct direction. Always ensure the tool is stationary before changing directions to prevent gear damage.
- Activation: Press the On/Off switch to start the tool; release it to stop.
- Socket Attachment and Alignment: Attach the appropriate drive socket insert to the square drive mount. Use the spirit level on top of the screwdriver to ensure the socket is straight on the wheel nut or bolt. The LED light will illuminate your work area when the tool is connected.
- Tightening Procedure:
- Place the drive socket insert firmly onto the wheel nut.
- For standard bolts (M12/M14), apply approximately 50 Nm of torque per pulse. Tighten each bolt with two pulses, and then apply an additional pulse for a final check.
- For heavier vehicles, use three pulses per bolt. Tighten the bolts in a crisscross pattern (diametrically opposed order), and then add an extra pulse. After tightening, inspect the threaded connections for any damage.
- Final Verification: Always verify and re-tighten the wheel nuts using a torque wrench, setting it to the manufacturer's recommended torque specifications.
Always adhere to the safety guidelines and instructions provided in the Einhell CC-HS 12/2 Car Hammer Screwdriver's manual for safe and efficient operation.
