Makita ACTUATOR GF600 - 452904-6
Genuine Makita actuator (part no. 452904-6) — direct replacement release/actuator for the Makita GF600 / GF600SE 7.2 V gas brad nailer. This molded actuator is the internal release/firing interface that transfers the trigger/drive motion to the nailer’s firing mechanism, restoring reliable cycling and consistent nail driving when the original has become worn or cracked.
Made to Makita specification from a durable, impact-resistant plastic with a black finish, the part is supplied as a single molded actuator and installs into the tool’s mechanism in place of the original. It is secured in position with a metric set screw (M3 × 4, Makita part 913904-6) as shown on the GF600 parts drawing, so you’ll only need basic hand tools to swap it out.
If your GF600/GF600SE is misfiring, sticking, or cycling unevenly, replacing this genuine Makita actuator (452904-6) restores the correct alignment and smooth actuation of the firing train so the tool runs like new again.
