To properly use the Einhell CC-HS 12/2 Car Hammer Screwdriver for tightening wheel nuts on your vehicle, follow these steps:
- Power Connection: Plug the 12V power plug into your car's cigarette lighter socket.
- Rotation Direction: Use the slide switch above the On/Off switch to set the direction of rotation. Always ensure the tool is stationary before changing the rotation direction to prevent gear damage.
- Activation: Press the On/Off switch to start the tool and release it to stop.
- Using the Impact Driver: Attach the correct drive socket insert to the square drive mount. Use the spirit level on the driver to ensure the socket is straight on the wheel nut/bolt. The LED light will illuminate the work area when connected.
- Tightening Wheel Nuts:
- Place the drive socket insert onto the wheel nut and activate the On/Off switch.
- Carefully align the bolt or nut with the thread before using the electric driver.
- For standard M12/M14 bolts, apply approximately 50 Nm of torque per pulse. Tighten each bolt with two pulses and then add one more pulse for good measure. Repeat this for all bolts.
- For heavy vehicles, use three pulses per bolt, tightening in a crisscross pattern, and then one additional pulse. Check for any damage after tightening.
- Final Torque Check: Always double-check and tighten the wheel nuts using a torque wrench, setting it to the manufacturer's specified torque value.
Always adhere to the safety precautions and guidelines outlined in the Einhell CC-HS 12/2 Car Hammer Screwdriver's instruction manual to ensure safe and effective use.
