    Autumn in the air so I have given my handy blower a full workout before its winter rest, having completed both gardens with no leaves in sight it was time for a full service,

    1) Drain all the fuel out of the fuel tank.
    2) Start engine and burn all petrol off in pipes,carburetor, and primer bulb,see pictures below.
    3) After 20 minutes of running drain the Engine oil.

    4) The 25CC engine takes 80ml of 10w-30 oil. I used Silkolene Comp 4 10w-30 XP Synthetic Ester, there is no oil filter in the tiny engine its a simple drain and refill. I used this metal cup for the exact amount.

    5) Fuel filter change, just remove the clip and install the new cotton type filter. To remove filter take a long nose plyer from the fuel filler and pull on the black tube.

    Fuel from the primer drained. I will have to change the primer next year as it changed colour to dark brown from transparent.

    6) Remove Air filter from its casing.

    Take the foam filter and soak it in foam filter cleaner, The products used are Silkolene.

    Soak the foam in the solvent for an hour and then wash thoroughly in water to remove all solvent, then leave over night covered to dry out naturally. Don't force dry it on raditors or blow air the foam will crumble,lessons learnt this from motocross days,:Wink:

    8) Check throttle free play

    9) Once the air filter is dry spray the foam oil liberally then squeeze the excessive out ensuring a tacky filter.

    10) Clean and wax the unit and store away.

    This blower was bought brand new in 2008 and had covered 900 hours with no issues only one spark plug and fuel filter changed for spares and countless oil changes. Oil changed after 10 hours.:Grin:

    Thanks Nelsy ,I did check the valve clearance and its still perfect even after 900 hours it has to be those quick oil changes which makes all the difference.

    I have just completed another service on the blower albeit one month early than last year. Yet again no issues just routine strip clean inspect and adjust.

    The hour meter now stands at 1098 hours. I may need to strip its timing belt.:wait:

    That's a lot of hours use for a leaf blower after 7 years.

    Sod that for once a year blowing leaves, car and bikes takes precedence.
