•
Using a lever-type grease gun, pump lithium-base grease (about 10 grams)
into the grease fitting until you see old grease being purged from the gear case,
this can be seen in the outer tube cavity.
Clean up excess grease, and then reassemble the gear case onto the outer tube
5. Use a wire hook to extract the fuel filter from inside the fuel tank (See
Fig.PP17).
CAUTION!
Make sure you do not pierce the fuel line with the end of the hooked
wire. The line is delicate and can be damaged easily.
Inspect the fuel filter element for signs of contamination.
Replace it with a new one if required. Before reinstalling the filter, inspect the fuel
line. If you find damage or deterioration, remove the unit from service until it can
be inspected by a trained service technician.
8.6.2 SHARPENING THE CHAIN
When the cutting edges of the blade become dull, they can be re-sharpened with
a few strokes of a file.
In order to keep the blade in balance, ail cutting edges must be sharpened
equally. In addition, inspect the chain for correct adjustment (more frequently with
a new chain).
The chain should feel snug but still pull freely. See Fig.PP18
8.6.3 SHARPENING INSTRUCTIONS (Fig.PP19)
IMPORTANT
: File all cutters to the same angle and depth! Unequal filing may
cause the saw to vibrate or cut erratically! –
-
Using a 4.5mm round file, sharpen all cutters to a 30° angle. Make sure that
one fifth (20%) of the file's diameter is always held above the cutter's top plate.
NOTE: For consistent filing angles, use a filing guide.
-
After all cutters are sharpened; use a depth gauge joiner to measure the
height of each depth gauge.
-
As required, lower the depth gauges to a height of 0.5mm. Use a flat file.
