Instrukcja instalacji
Środki ostrożności
- Always ensure the chainsaw engine is off and cool before beginning any maintenance or installation.

- Należy nosić odpowiedni sprzęt ochrony osobistej, obejmujący okulary ochronne i rękawice.

- Czyste szmaty
Kroki instalacji
- Przygotuj piłę łańcuchową: Ensure the chainsaw is turned off, cool, and the spark plug wire is disconnected. Place it on a stable, flat surface.
- Zlokalizuj pompkę zapłonową: Identify the existing primer bulb, typically located on the carburetor or engine housing.
- Dostęp do żarówki: You may need to remove a cover or air filter housing to gain access to the primer bulb and its fuel lines.
- Odłącz przewody paliwowe: Carefully note the routing of the fuel lines connected to the old primer bulb. There are usually two lines: an inlet from the fuel tank and an outlet to the carburetor. Use pliers if necessary to loosen any clamps, then gently pull the lines off. Be prepared for minor fuel leakage.
- Wyjmij starą żarówkę: Depending on the design, the old primer bulb may be pressed into a housing or secured with a clip. Carefully pry it out or unclip it.
- Zainstaluj nową żarówkę: Insert the new Mountfield primer bulb into the housing, ensuring it seats firmly and correctly.
- Ponowne podłączenie przewodów paliwowych: Reattach the fuel lines to the new primer bulb in the correct orientation. The longer line typically goes to the fuel tank (inlet), and the shorter line to the carburetor (outlet). Ensure connections are secure to prevent leaks.
- Ponowny montaż: Replace any covers or air filter housings that were removed.
- Sprawdź, czy nie ma wycieków: After reassembly, add a small amount of fuel to the tank if it's empty. Observe for any fuel leaks around the new primer bulb connections.
Działanie
The primer bulb's function is to manually draw fuel from the tank into the carburetor, ensuring a rich fuel mixture for easier starting, especially after the chainsaw has been sitting for a while or run out of fuel.
Zalewanie silnika
- Sprawdź, czy w zbiorniku paliwa znajduje się wystarczająca ilość paliwa.
- Locate the primer bulb.
- Press the primer bulb repeatedly (typically 5-10 times) until you see fuel flowing through the clear lines or the bulb fills with fuel. Some bulbs will become firm when primed.
- Once primed, proceed with your chainsaw's standard starting procedure.
Konserwacja
Regular inspection of the primer bulb can help prevent starting issues.
- Kontrola wizualna: Periodically check the primer bulb for cracks, hardening, or discoloration. A brittle or cloudy bulb may indicate it needs replacement.
- Fuel Line Check: Inspect the fuel lines connected to the primer bulb for any signs of cracking, leaks, or loose connections.
- Test funkcjonalności: If the engine is hard to start, check if the primer bulb draws fuel effectively when pressed. If it doesn't fill with fuel or feels spongy without resistance, it may be faulty.
- Czyszczenie: Keep the area around the primer bulb clean from dirt and debris to prevent contamination of the fuel system.
