Operating Manual

Chain Saw WG303E
When working on a slope, operate above or to the side
of the trunk or laying tree.
Be careful not to trip over tree stumps, branches, roots,
etc.
CUTTING WOOD UNDER TENSION (SEE FIG. L)
There is a high risk of accidents when sawing wood,
branch or trees under tension. Be extremely careful.
Leave saw jobs like these to professionals.
When sawing logs supported on both ends, start the
cut from above(Y) about 1/3 of the diameter into the
log and then finish the cut (Z) from below, in order to
avoid contact of the chain saw with the ground. When
sawing logs supported on only one end, start the cut
from below (Y) about 1/3 of the diameter into the log
and finish the cut from above (Z) in order to avoid log
splitting or jamming of the chain saw.
MAINTENANCE
Before any work on the machine itself, pull the
mains plug from the socket.
NOTE: To ensure long and reliable service, carry out the
following maintenance regularly.
Regularly check for obvious defects such as loose,
dislodged or damaged chain and guide bar, loose
fixings and worn or damaged components.
Check that covers and guards are undamaged and
correctly fitted. Carry out necessary maintenance or
repairs before using the chain saw.
If the chain saw should happen to fail despite the care
taken in manufacturing and testing, repair should be
carried out by an authorized customer service agent.
If the replacement of the supply cord is
necessary, this has to be done by the
manufacturer or his agent in order to avoid a
safety hazard.
Before returning, ensure all oil in the oil tank has
been emptied.
Replacing/Changing Chain and guide bar
Fit the chain and guide bar as described in “Assembly
and Tensioning Chain”.
The circular groove of the guide bar will wear
particularly on the lower edge with time. When
replacing the chain turn the chain bar 180° to allow even
wear, thus extending chain bar life.
Check drive sprocket. If it is worn out or damaged due
to strain, have it exchanged by an authorized service
agent.
