GGP Italy SPA Chain Saw P 680 Instructions Manual

							EN 105. Operating the Engine
Release the accelerator lever when the brake is
engaged. The chain must stop immediately as
soon as the brake is engaged.
If the brake is not working correctly, contact your
dealer for a check and repair.
The clutch will overheat if the engine remains at
a high number of revs with the brake engaged.
This can lead to damage to the clutch and the
brake belt.
Release the accelerator lever immediately if the
brake is engaged when working.
•ICING PREVENTION SYSTEM
This system prevents icing of the carburetor
which sometimes happen while sawing in winter.
When your saw has stopped or slowed down
abruptly, use the system as follows:
1. Remove the air cleaner cover, air filter, and
silencer.
2. Unhook the hatch on the rear wall of the cylin-
der cover and turn it upside down.
3. Install the covers as they are.
Never use the system in
normal temperature because that can cause
starting failure due to overheating of the car-
buretor.
!WARNING!•ANTI-FREEZE KIT
For use under extra cold condition. Optional
parts as shown right are available. When normal
air filter is frozen even with the hatch opened,
contact your nearest dealer for the anti-freeze kit
parts.
•STOPPING THE ENGINE
1. Release the throttle lever to allow the engine
to idle for a few minutes
2. Set the switch to the “O” (STOP) position.

•Before proceeding to
your job, read the sec-
tion “For Safe Oper-
ation”. It is recommend-
ed to first practice saw-
ing easy logs. This also
helps you get accus-
tomed to your unit.
•Always follow the safety
regulations. The chain
saw must only be used
for cutting wood. It is
forbidden to cut other
types of material.
Vibrations and kickback
vary with different mate-
rials and the require-
ments of the safety reg-
ulations would not be
respected. Do not use
the chain saw as a lever
for lifting, moving or
splitting objects. Do not
lock it over fixed stands.
It is forbidden to hitch
tools or applications to
the PTO other than
those specified by the
manufacturer.
•
It is not necessary to force the saw into the
cut. Apply only light pressure while running the
engine at full throttle.
•When the saw chain is caught in the cut, do
not attempt to pull it out by force, but use a
wedge or a lever to open the way.
•GUARD AGAINST KICKBACK

!WARNING!•This saw is equipped with
a chain brake that will
stop the chain in the
event of kickback if oper-
ating properly. You must
check the chain brake
operation before each
usage by running the saw
at full the throttle for 1-2
seconds and pushing the
front hand guard forward.
The chain should stop
immediately with the
engine at full speed. If the
chain is slow to stop or
does not stop, replace the
brake band and clutch
drum before use.
•It is extremely important
that the chain brake be
checked for proper oper-
ation before each use and
that the chain be sharp in
order to maintain the kick-
back safety level of this
saw. Removal of the safe-
ty devices, inadequate
maintenance, or incorrect
replacement of the bar or
chain may increase the
risk to serious personal
injury due to kickback.
•FELLING A TREE
1. Decide the felling direction considering the
wind, lean of the tree, location of heavy
branches, ease of completing the task after
felling and other factors.
2.While clearing the area around the tree,
arrange a good foothold and retreat path.
(1) Notch cut
(2) Felling cut
(3) Felling direction
6. Sawing   
						

							EN 126. Sawing
3. Make a notch cut one-third of the way into
the tree on the felling side.
4. Make a felling cut from the opposite side of
the notch and at a level slightly higher than
the bottom of the notch.
When you fell a tree, be
sure to warn neighboring workers of the dan-
ger.
Bucking and Limbing
•Always ensure your foothold. Do not stand
on the log.
•Be alert to the rolling over of a cut log.
Especially when working on a slope, stand
on the uphill side of the log.
•Follow the instructions in “For Safe
Operation” to avoid kickback of the saw.
Before starting work, check the direction of
bending force inside the log to be cut. Always
finish cutting from the opposite side of the bend-
ing direction to prevent the guide bar from being
caught in the cut.
A log lying on the ground
Saw down halfway, then roll the log over and cut
from the opposite side.
A log hanging off the ground
In area “A”, saw up from the bottom one-third
and finish by sawing down from the top. In area
“B”, saw down from the top one-third and finish
by sawing up from the bottom.

!WARNING!

!WARNING!Cutting the limbs of Fallen Tree
First check to which side the limb is bent. Then
make the initial cut from the bent side and finish
by sawing from the opposite side.
Be alert to the springing
back of a cut limb.
Pruning of Standing Tree
Cut up from the bottom, finish down from the
top.
•Do not work standing on unstable bases or
rung ladders.
•Do not overreach.
•Do not cut above shoulder height.
•Always use both your hands to hold the
saw.

							7. MaintenanceEN 13
Before cleaning, the
inspecting or repairing the unit, make sure
that engine has stopped and is cool.
Disconnect the spark plug to prevent acci-
dental starting.
•MAINTENANCE AFTER EACH USE
1. Air filter
Loosen the knob and remove the air cleaner
cover. 
Take off the filter element and brush off attached
sawdust. When the filter is clogged with dust,
separate it in halves and shake-wash with gaso-
line.
When servicing the air filter, be sure to block the
air intake hole with cloth.
2. Oiling port
Dismount the guide bar and check the oiling port
for clogging.
NOTE

!WARNING!3. Guide bar
When the guide bar is dismounted, remove saw-
dust in the bar groove and the oiling port.
Grease the nose sprocket from the feeding port
on the tip of the bar.
4. Others
Check for fuel leakage and loose fastenings and
damage to major parts, especially handle joints
and guide bar mounting.
If any defects are found, make sure to have them
repaired before operating the saw again.
•PERIODICAL SERVICE POINTS
1. Cylinder fins
Dust clogging between the cylinder fins will
cause overheating of the engine. 
Periodically check and clean the cylinder fins
after removing the air cleaner and the cylinder
cover. 
When installing the cylinder cover, make sure
that switch wires and grommets are positioned
correctly in place.
Be sure to block the air intake hole.

2. Fuel filter
1. Using a wire hook, take out the filter from the
filler port.
2. Disassemble the filter and wash with gaso-
line, or replace with a new one if needed.
•After removing the filter, use a pinch to hold
the end of the suction pipe.
•When assembling the filter, take care not to
allow filter fibers or dust inside the suction
pipe.
3. Oil tank
Drain the oil tank and clean the inside with gaso-
line.
4. Spark plug
Clean the electrodes with a wire brush and reset
the gap to 0.65 mm as necessary.
NOTE
5. Sprocket
Check for cracks and for excessive wear inter-
fering with the chain drive. If the wear is consid-
erable, replace it with new one. Never fit a new
chain on a worn sprocket, or a worn chain on a
new sprocket.
6. Front and Rear dampers
Replace if adhered part is peeled or crack is
observed on the rubber part. Replace if the
inside of the rear damper metal has been beaten
by the stopper bolt and the clearance of the
metal increased.(1) Weight

							7. Maintenance of Saw Chain and Guide BarEN 15
1. Saw Chain
It is very important for
smooth and safe operation to always keep
the cutters sharp.
The cutters need to be sharpened when:
•Sawdust becomes powder-like.
•You need extra force to saw in.
•The cut path does not go straight.
•Vibration increases.
•Fuel consumption increases.
Cutter setting standards
Be sure to wear safety
gloves.
Before filing:
•Make sure the saw chain is held securely.
•Make sure the engine is stopped.
•Use a round file of proper size for the chain
(7/32 in. - 5.6 mm).
Place the file on the cutter and push straight for-
ward.
Keep the file position as illustrated.
After each cutter has been filed, check the depth
gauge and file it to the proper level as illustrated.
Be sure to round off the
front edge to reduce the chance of kickback
or tie-strap breakage.
!WARNING!

!WARNING!

!WARNING!
Make sure every cutter has the same length and
edge angles as illustrated.
2. Guide Bar
•Reverse the bar occasionally to prevent partial
wear.
•The bar rail should always be square. 
Check for wear of the bar rail. Apply a ruler to the
bar and the outside of a cutter. If a gap is
observed between them, the rail is normal.
Otherwise, the bar rail is worn. Such a bar needs
to be corrected or replaced.
