If the saw chain or bar becomes jammed:
Switch the tool off.
x
Disconnect the tool from the mains supply.
x
Open the cut with wedges to relieve the strain
x
on the guide bar. Do not try to wrench the saw
free. Start a fresh cut.
Felling (fig. H - J)
Pre-plan a safe exit from falling trees or branches.
x
Cut one third of the diameter of the tree (Fig. H).
x
Then cut down from above to make a notch of
about 45°. This way you will avoid pinching the
saw.
Make a single felling cut from the other side
x
but stop before you cut through to the notch
(fig. I).
Drive a wedge or wedges into the felling cut to
x
open it and drop the tree (fig. J).
Logging (fig. K - M)
How you should cut depends on how the log is
supported. Use a saw horse whenever possible.
Always start a cut with the chain running and the
spiked bumper (15) in contact with the wood (fig. K).
To complete the cut use a pivoting action of the
spiked bumper against the wood.
When supported along its whole length
Make a downward cut, but avoid cutting the
x
earth as this will blunt your saw quickly.

MAINTENANCE (fig. N)
After every few hours of use, remove the guide
bar and chain and clean thoroughly.
On reassembling, the guide bar should be
turned through 180° and the sprocket nose
greased via the sprocket lubrication hole (18).
This ensures an even distribution of wear
around the guide bar rails.
