Likely causes

- PossibleLoose pivot bolt at the base plateA loose bolt lets the whole depth assembly shift.
What to do
- Unplug the saw or remove the battery before adjusting.
- Clean sawdust and debris out of the depth adjustment slot and pivot area.
- Set the desired depth and firmly close the lock lever or tighten the knob as far as it goes.
- Check the pivot bolt behind the depth scale for looseness and tighten it if needed.
- Test by pressing down on the base plate to see if the depth holds under pressure before cutting.
- If it still slips, inspect the lock lever's clamping surface for wear or stripping.
Tools and parts
