The operation will be easier using the file guide.
During sharpening the file must be positioned so as
determine the following three corners of the cutting:
"A" upper angle 30° - 35°
"B" external side angle 85° - 90°
"C" internal side angle 60°
2. The file must be positioned and must work perpendicularly
to the bar.
3. To obtain more precise side angles we advise positioning
the file so that you vertically cross over the cutting edge of
about 0,5 mm.
Sharpen all the teeth of one side first then turn the saw over
and repeat the operation.
To obtain a uniform cutting surface in the wood, all the teeth
must be sharpened to the same length.
4. CUTTING DEPTH DELIMITER
With the sharpness of the teeth the cutting depth decreases.
Check the height of the depth delimiters after various chain
sharpenings.
The exact height must be 0,025"/0,65 mm beneath the upper
cutting edge.
Check the height using the file and file down the jutting part.
Round the front part of the delimiter (D).
L3 DAILY MAINTENANCE
ATTENTION! Please be sure that the engine is
switched off before beginning any maintenance
operation.
Air Filter Clean the air filter at least once a day and more
often in difficult environments. To dismantle the filter, unscrew
the engine lid setscrews. Raise the lid, with the help of a
screwdriver, raise the filter and remove it. Shake or brush the
filter. For a more intense cleaning wash the filter with soapy
water.
During assembly, check that the filter closes well into its area.
The filter never becomes again completely clean and must
therefore be periodically replaced with a new one.
A damaged filter must be replaced immediately.
M1 Cutting Bar Carefully clean the oil passage flue (K) and
holes (l) (insert images). Turn the bar periodically to obtain
uniform performance in the event the guide groove is worn or
there are excessive furrows present. Clean the chain guide.
Grease the bar coil with fat for bearings.
M2 Chain Oil Pump Check that the automatic pump for bar
lubrication correctly pumps chain oil. Point the bar against a
clear surface, about twenty centimetres distant. After about a
minute, at ¾ gas, the surface will have to present clear oil
tracks. If the pump doesn't work correctly contact an
Authorized Assistance Centre.
Fuel Filter
To replace remove the tank cap and extract the filter using a
metal hook. Replace the filter, preferably at least once a year.
M4 Chain Sharpen the chain and check its condition and
tension. If it is worn-out, have it replaced at an authorized
assistance centre. When the cutting tooth is only 4 mm, the
chain is worn and must be replaced.
M3 Chain Drag Coil
Check that the chain drag coil is not worn. If the replacement
is necessary, refer to an authorized assistance dealer.
L4 Starting Device Check the starting device, the cord, and
clean the outside air intake. Check that the cord automatically
returns to its original position.
ATTENTION! In the starting device a tension
spring is present. Do not open the device to
avoid personal injury. If the starting device
turns out to be defective, contact an authorized
assistance centre for repairs.
Nuts and screws
Check that all nuts and screws are well tightened.
L4 Spark Plug
Clean the spark plug and check that the electrode has a
distance of 0.5 mm. Replace it if it is worn, using the suitable
key for the job.
ATTENTION!
replacement is necessary, use only the correct
type of spark plug as its replacement. Other
types could damage the engine.
