To reassemble the brake on a Qualcast 46 cc Petrol Chainsaw, you must follow the instructions in the Assembly Instructions booklet. The chain brake must be fitted exactly as described in the manual to ensure safety. It should not be tampered with, and improper assembly or careless use can still result in serious injury even if the brake is installed.

NO detailed step-by-step procedure for brake reassembly is provided in the available context.
