Adjust the latch

Tighten or loosen the latch

The Big Joe manual's latch page (p. 13) was copied from the Classic III ("The latch on your Classic III is already preset"), so this guide does not follow it. The latch is the same part as the Classic II's (KJ-SSLATCH): these are the Classic II manual's steps. Adjust it only when smoke leaks at the front with a good gasket.

1. Find the set screw in the latch plate.
2. Undo it with a small Allen key to lower the latch plate.
3. Add the spacer.
4. Refit the plate by tightening the set screw: right to tighten, left to loosen (Classic II 2019 manual).
5. Close the latch and check the seal all round.
