Step 1: Safety First
Before starting any maintenance task, it’s important to prioritize safety. Make sure the machine is turned off and the spark plug wire is disconnected. Wear protective gloves and safety goggles to protect yourself from any potential hazards.
Step 2: Removing the Old Disc
Begin by removing the disc guard. Use a wrench to hold the spindle lock while loosening the disc nut in a counterclockwise direction. Once the nut is loose, unscrew it by hand and carefully remove the old disc from the spindle. Be cautious as the disc might still be hot or sharp.
Step 3: Inspecting the Spindle
While the disc is off, take the opportunity to inspect the spindle for any signs of wear or damage. Look for cracks, chips, or excessive wear. If you notice any issues, it’s recommended to replace the spindle before installing the new disc.
Step 4: Installing the New Disc
Before installing the new disc, make sure it matches the specifications recommended by Stihl. Slide the new disc onto the spindle, ensuring that it aligns properly with the spindle flanges. Hand-tighten the disc nut in a clockwise direction while holding the spindle lock with the wrench. Once the nut is tight, use the wrench to give it an extra quarter turn for added security.
Step 5: Reattaching the Disc Guard
Finally, reattach the disc guard by sliding it over the spindle and aligning it with the mounting holes. Insert and tighten the screws or bolts to secure the guard in place. Double-check that the guard is properly positioned and doesn’t interfere with the disc’s rotation.
Note: Remember to always consult the user manual for specific instructions and guidelines provided by the manufacturer before attempting any maintenance tasks on your Stihl petrol disc cutter.
By following these steps, you will be able to change the disc on a Stihl petrol disc cutter with confidence. Regularly inspecting and replacing the disc when necessary will help ensure optimal performance and longevity of your machine. Stay safe and happy cutting!
