Felling Back Cut: Make the felling back cut (Y) at
least 50 mm higher than the horizontal notching cut.
Keep the felling back cut parallel to the horizontal
notching cut. Make the felling back cut so enough
wood is left to act as a hinge. The hinge wood keeps
the tree from twisting and falling in the wrong direc-
tion. Do not cut through the hinge.
As the felling gets close to the hinge the tree should
begin to fall. If there is any chance that the tree may
not fall in desired direction or it may rock back and
bind the saw chain, stop cutting before the felling
back cut is complete and use wedges of wood, plas-
tic or aluminium to open the cut and drop the tree
along the desired line of fall.
When the tree begins to fall remove the chain saw
from the cut, stop the motor, put the chain saw
down, then use the retreat path planned. Be alert for
overhead limbs falling and watch your footing.
To complete the felling operation, drive a wedge (Z)
into the horizontal cut.
Beware of falling branches when the tree starts to
move.
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 chain 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.
Before returning, ensure all oil in the oil tank has
been emptied.
For all correspondence and spare parts orders, al-
ways include the 10-digit part number (TYP) from
the nameplate of the machine!
Fit the chain and chain bar as described in “Assem-
bly and Tensioning Chain”.
The circular groove of the chain bar will wear partic-
ularly 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 21. If it is worn out or damaged
due to strain, have it exchanged by an authorized
Bosch service agent.
Have your chain sharpened professionally at your
Bosch approved service agent or sharpen the chain
yourself using the Bosch sharpening kit or a Dremel
power tool with the appropriate grinder (1453), both
available at your Bosch approved service agent. Fol-
low the sharpening instructions supplied with the
sharpening kit.
Proper functioning of the automatic oiler can be
checked by running the chain saw and pointing the
tip of the chain bar towards a piece of cardboard or
paper on the ground. Caution: Do not touch the
ground with the chain. Ensure safety clearance of
20 cm. If an increasing oil pattern developes, the au-
tomatic oiler is operating fine. If there is no oil pat-
tern, despite a full oil reservoir, see “Fault Finding” or
contact your Bosch approved service agent.
