The handle engages the chain brake of the Good Luck chainsaw: when pushed by the hand or on kickback, it tightens the brake band and stops the chain.
Replace it if it is cracked, broken, the mount has loosened, or the brake does not engage crisply. Checking the brake before work should be a habit.
When replacing, clean the seat of dirt, oil and sawdust and inspect the neighboring parts: a worn unit often drags the others with it.
