Can you start a chainsaw if the chain brake is broken?


A saw in good running condition will start with the chain brake on, or off…you can throttle it up little—rev the engine slightly—but the chain won’t move if the brake is engaged…

Occasionally a chain brake will stick in the brake on position…try moving the chain brake bar back and forward a couple of times…you should hear an audible click when it engages or disengages…

If you don’t hear a click the chain brake is faulty, or jammed…most small engine shops can replace it for you…it’s not a good idea to run a saw with a faulty chain brake…it provides operator protection in case of severe kickback, stopping the chain before it flies back into you…

Other causes for a chain not moving…chain too tight, broken clutch teeth, or an obstruction in the chain brake, bar nose sprocket, or bar chain rails…

If you’re handy with tools you can loosen the chain to see if it’s over-tight, or remove it completely and clean out the bar rails and see that the nose sprocket is not jammed…take off the side cover plate and check for debris that might be binding the chain at the clutch sprocket…

Truthfully, if you’re not handy with tools you probably shouldn’t own a chainsaw…they require regular adjustment and maintenance to operate safely…

Good luck…
