First, the spring must be loosened from the bottom of the splitter. We’ve previously used heavy duty cable ties to do this. Tie the cable ties together, so that you can pull the cable ties back through the hole at the end of the process.
After loosening off the spring, you can then slide the bottom blade up the splitter, towards the hole at the back of the splitter, designed for tightening the blade.
We recommend tightening the bolts on the blade up fully, and then taking the bolts back half a turn.
You can then pull the spring back using the cable ties and hook the spring back on. This will tighten up the bottom blade and stop the blade moving at an angle.
