Replacing a blade on the Q700 Carbide Circular Saw is a simple process when done correctly — but like any cutting tool, safety and installation direction matter. In this Sawblade.com Tech Tip, Austin Zimmerman demonstrates how to remove a worn blade, install a new one, and safely and adequately tighten the arbor.
Whether you're upgrading for a cleaner finish, switching tooth configurations, or replacing a blade that has reached the end of its life, the steps below will guide you through a safe and efficient Q700 blade change.
How to Change Your Q700 Blade
1) Disconnect the power
Unplug the saw from the wall or extension cord. Never change a blade while the machine is powered.
2) Engage the arbor lock
Press the arbor-lock button and rotate the blade until it locks in place. This prevents rotation during removal.
3) Remove the arbor nut
Use the supplied wrench and turn it in the same direction the blade cuts to loosen the nut. Reverse-threading prevents accidental loosening during use.
4) Retract the blade guard
Lift or retract the upper guard, then carefully remove the old blade, keeping your hands clear of the teeth.
5) Mount the new blade
Slide the replacement blade onto the arbor. Ensure the teeth face the correct rotation — match the blade to the arrow on the guard if uncertain.
6) Tighten the arbor nut
Reinstall the nut and tighten until firmly snug. Do not over-tighten — the nut should be secure, but still serviceable for future blade changes.
Once installed, spin the blade by hand to confirm clearance and smooth rotation before reconnecting power.
