To properly tighten wheel nuts with your Einhell CC-HS 12/2 Car Hammer Screwdriver, follow these steps:
- Power Connection: Plug the 12V power plug into your vehicle's cigarette lighter socket.
- Rotation Direction: Use the slide switch above the On/Off switch to set the direction of rotation. Ensure the tool is at a complete standstill before changing directions to prevent gear damage.
- Powering On/Off: Press the On/Off switch to activate the tool and release it to turn it off.
- Using the Impact Driver: Attach the correct drive socket insert to the square drive mount. Use the spirit level on top of the driver to ensure the socket is straight on the wheel nut or bolt. The LED light will illuminate when connected to the power supply.
- Tightening the Nuts:
- Place the drive socket insert onto the nut head and press the On/Off switch.
- Carefully align the bolt or nut into the threads before using the electric driver.
- For standard M12/M14 bolts, apply approximately 50 Nm of torque per pulse. Tighten with two pulses initially, and then add a third pulse to each bolt.
- For heavier vehicles, use three pulses per bolt, tightening in a diametrically opposed sequence, and then add an additional pulse.
- Inspect the threaded connections for any damage after tightening.
- Final Step: Always check and retighten wheel nuts to the manufacturer's specified torque using a torque wrench.
Always adhere to the safety precautions and guidelines provided in the Einhell CC-HS 12/2 instruction manual for safe and effective use of the car hammer screwdriver.
