JM21000239 supersedes older part numbers: JM21000082
Makita JM21000239 — genuine Makita blade‑guide height adjust (lifting) knob for the LB1200F 305 mm band saw. This part fits into the upper blade‑guide lifting assembly (item 59 on Makita parts diagram) and is the control knob you turn to set and lock the upper blade‑guide height.
Designed to work with the LB1200F guide hardware, the knob interfaces with the assembly’s M8 locking nut and associated washer / spring components listed in the parts breakdown, so it installs directly in place of the original knob.
If your LB1200F’s blade‑guide adjust knob is worn, cracked, or missing, this genuine Makita replacement restores smooth manual height adjustment and secure locking of the upper guide so you can get back to accurate cutting.
