CLEANING AND MAINTENANCE
CAre Of Guide bAr
Uneven bar wear causes most guide bar prob-
lems. Incorrect sharpening of chain cutter 
and depth gauge settings often cause this. 
When bar wears unevenly, it widens guide 
bar groove (see Figure 30). This causes chain 
clatter and rivet popping. Saw will not cut 
straight. Replace guide bar if this occurs.
Inspect guide bar before sharpening chain. 
A worn or damaged guide bar is unsafe. A 
worn  or  damaged  guide  bar  will  damage 
chain. It will also make cutting harder.
CLeAninG SAW bOdy
NOTICE:  Below  are  instructions
for servicing your chain saw. Any
servicing  not  mentioned  below
should be done by an authorized
service center.
 wARNING:  Remove  battery
from chain saw before servicing.
Severe  injury  or  death  could  oc-
cur from body contact with mov-
ing chain.
wARNING: Cutting edges on
chain  are  sharp.  Use  protective
gloves when handling chain.
wARNING: when cleaning saw
body,
•  do not submerge saw in
any liquids
•  do  not  use  products
that  contain  ammonia,
chlorine, or abrasives
•  do  not  use  chlorinated
cleaning solvents, carbon
tetrachloride,  kerosene,
or gasoline
Keep saw body clean. Use a soft cloth damp-
ened with a mild soap and water mixture. 
Wipe saw body to clean.

Normal Guide Bar Maintenance
1.  Remove guide bar from chain saw.
2.  Remove  sawdust  from  guide  bar 
groove  periodically.  Use  putty  knife 
or wire (see Figure 31).
3.  Clean oil slots after each day of use.
4.  Remove  burrs  from  sides  of  guide 
bar.  Use  flat  file  to  make  side  edges 
square.
Replace guide bar when
•  bar is bent or cracked
•  inside groove of bar is badly worn
4.  Hold file guide level. Make sure 30° 
mark on file guide is parallel to cen-
ter of guide bar (see Figure 33). This 
will insure that you file cutters at 30° 
angle.
5.  File  from  inside  towards  outside  of 
cutter until sharp. Only file in this one 
direction (see Figure 33). 
note: Two or 
three strokes with file should sharpen 
cutter. 
6.  After each cutter is sharpened, move 
chain forward to sharpen next cutter. 
File all cutters on one side of chain.
7.  Move to other side of chain and repeat 
process.
 wARNING:  Remove  battery
from chain saw before servicing.
Severe injury or death could oc-
cur from body contact with mov-
ing chain.
 wARNING:  Cutting edges  on
chain  are  sharp.  Use  protective
gloves when handling chain.
ShArPeninG SAW ChAin
Keep chain sharp. Your saw will cut faster 
and  more  safely.  A  dull  chain  will  cause 
undue sprocket, guide bar, chain, and motor 
wear. If you must force chain into wood and 
cutting creates only sawdust with few large 
chips, chain is dull.
Items Needed to Sharpen Chain
Purchase  these  items  from  your  local 
dealer,  hardware  store,  or  chain  saw  sup-
plies outlet.
•  5/32" round file
•  Depth gauge tool
•  File guide
•  Vise
•  Medium sized flat file

Sharpening Cutters
Use file guide for 30° filing. 
1.  Adjust  chain  for  proper  tension  (see 
Saw Chain Tension,
 page 11).
2.  Clamp guide bar in vise to hold saw 
steady. 
note: Do not clamp chain.
3.  Press 5/32" round file (attached to file 
guide) into groove between top plate and 
depth gauge on chain. File guide should 
rest on both top plate and depth gauge 
(see Figure 32). 
note: File at midpoint 
of guide bar.
