STORING THE PRODUCT
Clean all foreign material from the product. Store it in
a well-ventilated place that is inaccessible to children.
Keep away from corrosive agents such as garden
chemicals and de-icing salts.
Observe local regulations for the safe storage and
handling of petrol.
When storing 1 month or longer:
1. Drain all fuel from tank into a container approved for
petrol.

fuel-lubricant mix that could become stale and leave
varnish and gum in the fuel system.
3. Squeeze primer bulb several times to purge fuel from

4. Drain all bar and chain lubricant from tank into a
container approved for lubricant.
Always place the scabbard over the guide bar and chain
