How to use

Before installation, disconnect spark plug and drain or block fuel flow to prevent leaks. Remove the chainsaw cover and air filter to access the carburetor, then detach fuel lines, throttle linkage and mounting screws. Fit the replacement carburetor in the correct orientation, reconnect fuel lines and linkage, and secure mounting fasteners to the manufacturer's torque recommendations. Reinstall the air filter and cover, reconnect the spark plug, and start the engine. Allow the engine to reach operating temperature and perform idle and mixture adjustments using the carburetor screws until smooth idle and proper throttle response are achieved.

Usage recommendations

Use fresh petrol mixed with the correct ratio of two-stroke oil, keep air filter and intake passages clean, and perform small adjustments to idle and mixture screws in small increments. If unsure about tuning or fitment, consult a qualified service technician or refer to the chainsaw’s maintenance manual.
