CORRECT- 80° Produced automatically if
correct diameter file is used in file holder.
HOOK-“Grabs”anddullsquickly.Increases
potentialofKICKBACK.
Results from using a file with diameter too small,
or file held too low.
BACKWARDSLOPE -Needstoo muchfeed
pressure, causesexcessive wear tobar and
chain.
Results from using a file with diameter too large,
or file held too high.
DEPTH GAUGE CLEARANCE
See Figures 40 - 41.
The depth gaugeshould bemaintained at a
clearanceof.025in.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andadepthgaugejointertolower
allgauges uniformly.Depth gaugejointers are
availablein.020in.to.035in.Usea.025in.depth
gaugejointer.Afterloweringeachdepthgauge,
restoreoriginalshapebyroundingthefront.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
See Figure 42.
CAUTION:
Makesurethechainhasstoppedandthebat-
terypackhasbeenremovedbeforeyoudoany
workonthesawtoavoidpossibleinjury.
Propermaintenancewillmaximizetheusefullife
of the guide bar.
Each day of use:
Clean the bar and check for wear and damage.
Feathering or burring of the bar rails is a normal
processofbarwear,butsuchfaultsshouldbe
smoothed with a file as soon as they occur.
