SAW CHAIN MAINTENANCE
If you have any questions or troubles, please
contact your Bushranger
™
dealer.
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 profiles throughout its life as
when it was new. Inspect the chain for damage or
wear every time you refuel your chain saw. When
the length of the cutting teeth has worn down to
only 4 mm the chain must be replaced.
a.
Lock the chain - push hand guard forward.
To rotate the chain - pull hand guard against front
handle.
b.
Your chain will have alternative left and right
hand cutters. Always sharpen from the inside out.
c.
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.
d.
Hold the file tipped 10
°
upward.
e.
Sharpen the most damaged cutter first and then
take all the other cutters back to the same length.
a.
The depth control determines the thickness
of wood chip produced and must be maintained
correctly throughout the chain life.
b.
As the cutter length is reduced, the depth
control hight is altered and must be reduced.
c.
Position the depth gauge, and file off any of the
depth control which protrudes.
d.
Round off the front of the depth control to allow
smooth cutting.
PRECAUTION
• As the cutter length is reduced, the depth
control height is altered and must be reduced.
•
Position the depth gauge, and file off any of the
depth control which protrudes.
• Round off the front of the depth control to allow
smooth cutting.
SHARPENING
In order to file the chain correctly you need:
round file and file holder (A), flat file (B) and a
depth gauge tool (C).
By using the correct file size (4.6 mm Round file)
and a file holder, it is easier to receive a good
result. Consult your dealer for correct sharpening
tools and sizes.
WARNING DANGER
Switch off the engine before sharpening the chain.
Always wear appropriate gloves when using
equipment.
Properly filed cutters are shown below.
a.
Top plate angle 30º.
b.
Side plate angle 85º.
c.
Top plate cutting angle 60º.
d.
Depth gauge 0.64 mm.
NOTE
These angles are referred to as Oregon branded
chain. For other branded saw chain, follow it’s
chain manufacturer’s instruction.

4. Hold the file tipped 100 upward.
5. Sharpen the most damaged cutter first and then take
all the other cutters back to the same length.

4. Round off the front of the depth control to allow

The following faults will increase the risk of kickback
considerably.
1) Top plate angle too large
2) Side plate angle too small

- When setting of the chain is finished, soak it in oil
and wash away filings completely before using.
- When 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.
