TOP PLATE FILING ANGLE
See gure 57.
(A)Correct30°–leholdersaremarkedwithguidemarks
toalignleproperlytoproducecorrecttopplateangle.
(B)Lessthan30°–forcrosscutting.
(C)Morethan30°–featherededgedullsquickly.
SIDE PLATE ANGLE
See gure 58.
(D)Correct 80°–producedautomatically ifyouuse the
correctdiameterleintheleholder.
(E) Hook – “Grabs” and dulls quickly, increases the
potential of kick-back. Results from using a le with a
diametertoosmalloraleheldtoolow.
(F) Backward slope – needs too much feed pressure,
causesexcessiveweartothebarandchain.Resultsfrom
usingalewithadiametertoolargeorleheldtoohigh.
MAINTAINING DEPTH GAUGE CLEARANCE
See gure 51. See gure 59 - 60.
■ Maintainthedepthgauge(A)ataclearanceof0.6mm
(0.025inch).Useadepthgaugetoolforcheckingthe
depthgaugeclearances.
■ Everytimethechainisfiled, checkthedepthgauge
clearance.
■ Use a flat file(B) (notprovided) and a depth gauge
jointer(C)(notprovided)tolowerallgaugesuniformly.
Usea0.6mm(0.025inch)depthgaugejointer.After
lowering each depth gauge, restore original shape
by roundingthe front(D). Be carefulnot to damage
adjoiningdrivelinkswiththeedgeofthefile.
■ Depthgaugesmustbeadjustedwiththeflatfileinthe
samedirectiontheadjoiningcutterwasfiledwiththe
roundfile.Usecarenottocontactcutterfacewithflat
filewhenadjustingdepthgauges.
MAINTAINING THE GUIDE BAR
