2. Open the oil tank cap. Only use bio-degradable chain saw oil.
Observe the oil level indicator on the oil tank. The oil tank has
to be filled at least up to the half. While filling, make sure dirt
cannot get into the oil tank. Dirt can damage the built-in oil
pump.
Saw Chain
 Only use sharp chains. Dull chains easily can get jammed.
 While working with new chains, regularly check the chain
tension because new chains can lengthen considerably upon
initial operation.
 The service life of a saw chain mainly depends on sufficient
lubrication and correct tensioning.
 Do not tension a hot chain again. After cooling down, the chain
may shorten and therefore becomes over tensioned.
Strain Relief
While working with the pole saw the
power cord might be inadvertently
unplugged. To avoid unplugging,
fasten the power cord and the
extension cord together, as shown
in the picture, by using the included
strain relief (11).
