Maintenance and care
Sharpening
In order to file the chain correctly you need: round file and file
holder, flat file and a depth gauge tool.
By using the correct file size (90PX; 4.5 mm Round file) and a
file holder, it is easier to receive a good result.
Consult your ECHO dealer for correct sharpening tools and sizes.
1.
Lock the chain - push the front hand guard forward. To rotate
the chain - pull the front hand guard against front handle.
2.
Your chain will have alternative left and right hand cutters.
Always sharpen from the inside out.
3.
Keep the angle lines of the file holder parallel to the line of
the chain and file the cutter back until the damaged area
(side plate and top plate) has been removed.
4.
Hold the file horizontally.
5.
Avoid touching the tie straps with the file.
6.
Sharpen the most damaged cutter first and then take all the
other cutters back to the same length.
7.
The depth control determines the thickness of wood chip
produced and must be maintained correctly throughout the
chain life.
8.
As the cutter length is reduced, the depth control height is al-
tered and must be reduced.
9.
Position the depth gauge, and file off any of the depth control
which protrudes.
10. Round off the front of the depth control to allow smooth cut-
ting.
11. Drive link serves to remove sawdust from the groove of the
guide bar. Therefore, keep the lower edge of the drive link
sharp.
When setting of the chain is finished, soak it in oil and wash
away filings completely before using.
When the chain has been filed on the bar, supply sufficient oil
to it, and rotate the chain slowly to wash away the filings before
using again.
If the chain saw is operated with filings clogged in the groove,
the saw chain and the guide bar will be damaged prematurely.
If the saw chain becomes soiled with resin for instance, clean
it with kerosene and soak it in oil.
