Log Supported On Both Ends
1.Make first cut from above log (see Figure Q). Cut 1/3 through diameter of log. This cut will keep section from splintering when cut.
2.Make second cut on underside of log, directly under first cut. Use top of guide bar to make this cut. Cut up to meet first cut. This will keep log from pinching guide bar and chain.

CLEANING AND
MAINTENANCE
NOTICE: Below are instructions for servicing your chain saw. Any servicing not mentioned below should be done by an authorized service center.
CLEANING SAW BODY
Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture. Wipe saw body to clean.
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
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. 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
SHARPENING YOUR SAW CHAIN
!WARNING: Unplug chain saw from power source before servicing. Severe injury or death could occur from electrical shock or body contact with moving chain.
!WARNING: Cutting edges on chain are sharp. Use protective gloves when handling 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 supplies outlet.
• 4 mm 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 Adjustment).
2.Clamp guide bar in vise to hold saw steady. Note: Do not clamp chain.
3.Press four millimeter 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 Figures R and S). Note: File at midpoint of guide bar.
4.Hold file guide level. Make sure 30° mark on file
guide is parallel to center of guide bar (see Figure R). 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 R). Note: Two or three strokes with file should sharpen cutter.
6.After each cutter if 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.

Filing Cutter Depth Gauges
The cutter depth gauge clearance is reduced as cutters are sharpened. After every second or third sharpening, reset cutter depth gauges.
1.Place depth gauge tool firmly across top of two cutters. Make sure depth gauge enters slot in depth gauge tool (see Figure T).
2.Use medium flat file. File depth gauge level with depth gauge tool.
3.Remove depth gauge tool. With flat file, round off front corner of cutter depth gauge (see Figure U).

After several hand filings, have authorized service center or sharpening service machine sharpen chain. This will insure even filing.
REPLACING SAW CHAIN
Replace chain when cutters are too worn to sharpen or when chain breaks. Only use replacement chain noted in this manual. Always include new drive sprocket when replacing chain. This will maintain proper driv- ing of chain.
RECYCLING
In the event it is not practical to repair your chain saw, be sure to follow local and country codes for recycling plastic and metallic materials when disposing of the unit.
STORAGE
If storing saw for more than 30 days, follow steps below.
1.Drain oil tank.
2.Remove and clean guide bar and chain. Clean guide bar and chain by soaking in petroleum based solvent or mild soap and water mixture.
3.Dry guide bar and chain.
4.Place chain in container filled with oil. This will prevent rust.
5.Wipe a thin coating of oil over surface of guide bar.
6.Wipe off outside of saw body. Do this with soft cloth dampened with a mild soap and water mixture.
7.Store chain saw in a high or locked place that is dry and out of children’s reach.
