CHAIN TENSION

of
the guide bar, the
cI1ain is snug, bul it can be turned by hand wHhoul binding.
Chain must be re-tensioned whenever the fiats on the dhvs links
hang out ofthe bar groove.
During nonmal saw operation, the temperature of the cI1aln will
Increase, The dlive links 01 a correctly tensioned warm chain wiil
hang approximately .050 in. (1.25mm) out of the bar groove, Be
aware that chain tensioned while wanm, may be too tight upon
cooling, Check the "cold tension" before next use,
NOTE: A new chain tends to stretCh, check chain tension frequently
and tension as required,
CHAIN MAINTENANCE
CAUTION: Disconnectfrom the power supply and make sure the

chain requires sharpening when the wOOd chips are small and powdery,
the chain must be famed through the wOOd during cutting, or the chain

HOW TO SHARPEN THE CUTTERS
8e careful 10 file all cutters to the spacified angles and to the
same length, as fast cutting can be obtained only when all cutters
are uniform.
Wear gloves for protection,

tension the chain pno, to
sharpening, Refer to "Chain Tension Section" earlier in this
manual. Do all of your filing at the midpoint of the bar.
Use a 5132 in, diameter round file and holder.
Keep the fila level with the top plate
of the tooth. Do not let the file dip or
rock, Using light but firm pressure,

Put a lew fil:'" strokes on every tooth, File alilef! hand cutters in
one direction. Then move to the other side and file the right hand
cutters in the opposlte direction, OccaSionally remove filing from
the file with a wire brush,
WARNING: Improper ellain sharpening increases the potential
of kickback,
WARNING: Failure to replace or repair damaged chain can cause
serious inlury.
WARNING: The saw chain is very sharp, always wear protective
gloves when performing maintenance to the cham,
TOP PLATE FILING ANGLE
Co!!'ec! 30 degrees - File holders are mali<:ed with guide marks to
align file propany to produce top plate angle,
less than 30 degrees - for
cross cutting,
More than 30 degrees -feath
ered edge dulls quickly,
SIDE PLATE ANGLE
Cocec! - 80 degrees produced automatically if correct diameter
file is used in file holder.
Hook - "Grabs' and dulls quickly,
Increases poter.tial 01 kickback.
Results from using a file with a
diameter too small, or file held
to low,
Backward Slope - Needs too much
feed pressure, causes excesslve
wearto bar and chain. Results from
using a file with a diameter too large, ortile held too high
DEPTH GAUGE CLEARANCE
The depth gauge Should be
maintained at a clearance of .025 in,
(0,6 mm), Use a
gauge tool
for checking the
gauge
clearances
Every time the cI1ain is flied, cI1eck the depth gauge clearance
Use a fiat file and a depth gauge jointer to lower all gauges
unffonmly. Depth gauge jOinters
are available in ,020 in, to .035 In,
(0,5 mm to 0,9 mm), Use a
025 in. (0.6 mm) depth gauge
jointer. After lowering each depth
gauge, restore ortginal shape by
rounding !he front. 8e careful not
to damage adjoining drive links
with the edge
of
the file,
Depth gauges must
be
adjustad wfth
the fiat file in the same direction the
adjoining cutter was filed wfth the
round file. Use care not to contact
cutter face with
flat file
when
adjusting depth gauges,
