Saw Chain
HOW TO SHARPEN CHAIN
▲ Sharpen chain before each use.
■ Sharpen chain often, or as needed.
READ THE WARNING ON PAGE 17.
Sharpening your chain while it is on the saw requires
proper chain tension, as shown on pages 18-21 prior
to filing.
Pages 35-63 show the correct maintenance specifi-
cations and the correct maintenance-tool part num-
bers for each of the Oregon
®
chain types. Find the
page which gives the correct filing specifications for
your Oregon
®
chain. To do so, use the Chain
Identification chart on pages 9-11.
If unsure of your Oregon
®
chain’s type, or part
number, ask your Oregon
®
saw chain dealer, or
call the Oregon
®
technical services department at
503-653-4706 between the hours of 7:30 am and
4:00 pm, Pacific time, Monday through Friday.
BEFORE & AFTER SHARPENING YOUR CHAIN
1. Before sharpening your chain, clean oil and grease
from the chain. This will prevent build-up in your
file’s teeth, or on the wheel when grinding.
2. Before sharpening, inspect, repair, or replace
damaged chain.
3. During your inspection, check for each of the
following:
• Proper installation of tie straps and drive links.
• Cracked or broken cutters, cutter top plates,
or tie straps.
• Bent, cracked or burred drive links.
• Severe abrasive damage.
