Transportation and storage
• For storage and transportation of the product and
fuel, make sure that there are no leaks or fumes.
Sparks or open flames, for example from electrical
devices or boilers, can start a fire.
• Always use approved containers for storage and
transportation of fuel.
• Empty the fuel and chain oil tanks before
transportation or before long-term storage. Discard
the fuel and chain oil at an applicable disposal
location.
• Use the transportation guard on the product to
prevent injuries or damage to the product. A saw
chain that does not move can also cause serious
injuries.
• Remove the spark plug cap from the spark plug.
• Attach the product safely during transportation.
