1. Prepare the chain: align the new saw chain with the ball locator on the sprocket of the saw chain, and carefully check whether there is any foreign matter on the saw blade, or whether the surface of the first four-button saw blade and the screw (bolt) fixed saw chain are damaged. 2. Install a new chain: align the reverse ball of the saw chain with the positioning hole of the saw chain gear with a pin (file), then put the first four buckles and bolts (bolts) of the saw blade back in the correct position and tighten them.

3. Molding a new chain: Take down the old chain according to the installation procedure 1, then fix the new chain on the table with a rubber roller, and arrange the new chain neatly according to the strip shape. Be careful not to deform the ball hole or ball locator on the saw chain.

4. Install the complete chain: wrap the plastic deformed saw chain and the ball locator with adhesive tape, so that the complete new saw chain can be installed on the saw chain teeth. Tighten the first four buttons of the saw blade and the screw (bolt) to complete the installation.
