Properly led cutters are shown below.
A : Top plate angle 30° (N1C-BL: 35°)
B : Top plate cutting angle 55° (9N1C-BL:
60°)
C : Depth gauge 0.65 mm (N1C-BL: 0.56 mm)
D : Parallel

In order to le the chain correctly you need:
round le and le holder (A), at le (B) and a
depth gauge tool (C).
By using the correct le size (4.0 mm Round
le) and a le holder, it is easier to receive a
good result.
Consult your shindaiwa dealer for correct
sharpening tools and sizes.

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 higtht is altered and must be
reduced.
9. Position the depth gauge, and le off any of
the depth control which protrudes.
10. Round off the front of the depth control to
allow smooth cutting.
CAUTION
The following faults will increase the
risk of kickback considerably.

1. Lock the chain - push hand guard forward.
To rotate the chain - pull 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 le holder
parallel to the line of the chain and le the
cutter back until the damaged area (side
plate and top plate) has been removed.

the groove of the guide bar. Therefore, keep
the lower edge of the drive link sharp.

These angles are referred to as Oregon 25AP,
91PX, 91V and Carlton N1C-BL. For other
branded saw chain, follow it's chain
manufacturer's instruction.
Never operate a chain saw with a dull or
damaged chain. If the chain requires
excessive pressure to cut or produces dust
instead of wood chips then inspect the cutters
for damage. When sharpening the chain the
objectives will be to maintain the same angles
and pro les throughout its life as when it was
new.
Inspect the chain for damage or wear every
time you refuel your chain saw.

4. Hold the le horizontally.
5. Avoid touching the tie straps with the le.
6. Sharpen the most damaged cutter rst and
then take all the other cutters back to the
same length.
■ When setting of the chain is nished, soak
it in oil and wash away lings completely
before using.
■ When chain has been led on the bar,
supply suf cient oil to it, and rotate the
chain slowly to wash away the lings
before using again.
■ If the chain saw is operated with lings
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.
