Chain Sharpening - Tanaka TCS 40EA Instructions De Sécurité Et Mode D'emploi

English
Cleaning the cylinder fi ns (Fig. 39)
When wood chips are caught between cylinder fi ns (40), the engine
may overheat, resulting in lower output. To avoid this, always keep
cylinder fi ns and fan case clean.
Every 100 operating hours, or once a year (more often if conditions
require), clean fi ns and external surfaces of engine of dust, dirt and
oil deposits which can contribute to improper cooling.

Cleaning the muffl er (Fig. 40)
Remove the muffl er and spark arrestor, if so equipped, and clean out
any excess carbon from the exhaust port or muffl er inlet every 100
hours of operation.
For long-term storage
Drain all fuel from the fuel tank. Start and let engine run until it stops.
Repair any damage which has resulted from use. Clean the unit with
a clean rag, or the use of high pressure air hose. Put a few drops of
two-cycle engine oil into the cylinder through the spark plug hole,
and spin the engine over several times to distribute oil.
Cover the unit and store it in a dry area.

LOWERING DEPTH GAUGES WITH A FILE
1) If you sharpen your cutters with a fi le holder, check and lower the
depth.
2) Check depth gauges every third sharpening.
3) Place depth gauge tool on cutter. If depth gauge projects, fi le
it level with the top of the tool. Always fi le from the inside of the
chain toward an outside cutter. (Fig. 43)
4) Round off front corner to maintain original shape of depth gauge
after using depth gauge tool. Always follow the recommended
depth gauge setting found in the maintenance or operator
manual for your saw. (Fig. 44)
