CLEANING SAW BODY
Keep saw body clean. Use a soft cloth dampened with a mild
soap and water mixture. Wipe saw body to clean. Let dry
before using saw.
CARE OF GUIDE BAR
Uneven bar wear causes most guide bar problems. Incorrect
sharpening of chain cutter and depth gauge settings often cause
this. When bar wears unevenly, it widens guide bar groove (see
Figure 18). 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.

Normal Guide Bar Maintenance
1. Remove guide bar from chain saw.
2. Remove sawdust from guide bar groove periodically. Use
putty knife or wire.
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
Note:
When replacing guide bar, see Replacement Parts, page
14 for proper bar.
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
SHARPENING YOUR 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 Echo servicing dealer.
