HOMELITE
SAWCHAIN
Your saw has a fast-cutting chain with a sprocket which
matchesit in pitch. Whenthe chain is to be replaced,
alwaysinstall
a newsprocketofmatching
pitch
because
a worn sprocketwould be out-of-pitchand damagelhe
newchain.
Notonly
lor fastestcutting,butalso
for maximumlife
of
the chain and all saw parts, alwayskeep the chain in
such good, sharpconditionthat bearingdown hard to
makelhe chain cut ls unnecessary.Whenthe sawdust
turnsfrom chipsinto a line powderand you lind your-
sell pressing hard to feed the chain, STOP IMMEDI-
ATELYandlile the chain.
Uniformity
and accuracyare necessaryfor successin
liling saw chain.Theseare easiestto obtainwith a file
holder which has the required 35o top filing angles
marked on it, and also holds the lile at correct height
(1/10 ol file diameterabove
top plateof tooth)to pro-
ducetherequiredside
plaleangleandcultingedge.
For new 3/8 pitch chain, a 7132 diameler "fast-cut"
round file and holder (our assemblyA-23133-A)is re-
quired.
Whenabout halfof the originaltooth steelhas
been liled away,you should switch first to a 13164"
diameferfile and lateron lo a 3116tt diameterfile.The
reasonfor using a smaller diameterlile is the slight
taperof the tooth's top plate which reduces the tooth
size.
HOWTO FTLE
CUTTERS
A chain liling vise holds the cutters rock-steadyfor
filing;but you can do a satisfactory
job "on the bar" if
you tightenup the tensiona bit so the chain does not
wobble,
anddo all of thefiling nearthe midpointof the
bar. ALWAYS WEAR GLOVES OR PROTECTYOUR
HANDSWITHA RAG
WHENWORKING
ON
THE
CHAIN.
Be
sure
to fileall cutters to lhe samelength
- if youre-
place
worn cutters,lile the newonesbackto the same
lengthasthe otherteelh in the loop so that all cutters
getabiting
chance.
Here'sWhat
YouShouldDo:
1. Holdfileagainst
cutterlaceat 35oangle
(marked
on
fileholder).
2. Keepfilelevel
- do notlet it dipor rock.
3. File in one direDtiononly-towards lront corner ol
the tooth. Movefile awayfrom tooth face on return
stroke.
4. Uselight but lirm pressure,
mostlytowardsback ol
tooth. Avoid heavy downward filing pressure. The
hofderwill keep10o/ool lhe tile abovethe lop plate,
automatically producing a beveled hollow-ground
underedge.
5. Putafew lirmstrokes
