POLE PRUNER 750W TTB426GDO
8. SHARPENING SAW CHAIN
It is highly recommended that, once the saw chain loses its
ability to cut cleanly and safely, it is replaced. It is possible,
however, to sharpen the existing chain if done carefully. (See
Fig.17a, 17b & 17c)
1). Ensure the chain is correctly tensioned.
2). Use a round file with a diameter of 1.1 times the cutting
tooth depth. Make sure 20% of the file diameter is above the
cutter’s top plate.
3). File at an angle perpendicular to the bar, and at an angle
of 25° to the direction of travel.
4). File each tooth from the inside towards outside only. File
one side of the chain first, then turn the pruner around and
repeat the process.
5). Sharpen each tooth equally by using the same number
of strokes.
6). Keep all cutter lengths equal.
7). Check the safety depth gauge height every 5
sharpenings.
8). If the depth gauges are also trimmed it is essential that
the original profile be restored.
9). Use a depth gauge measuring instrument to check the
height of the depth gauge.
