OPERATING CHAIN SAW

Continued

Trimming a tree is the process of cutting limbs from a living tree. Make sure your footing is Þrm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to trim a tree.

1.Make Þrst cut six inches from tree trunk on un- derside of limb. Use top of guide bar to make this cut. Cut 1/3 through diameter of limb (see Figure 18).

2.Move two to four inches farther out on limb. Make second cut from above limb. Continue cut until you cut limb off.

3.Make third cut as close to tree trunk as possible on underside of limb stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of stub.

4.Make fourth cut directly above third cut. Cut down to meet third cut. This will remove limb stub.

CLEANING AND

MAINTENANCE

NOTICE: Below are instructions for ser- vicing your chain saw. Any servicing not mentioned below should be done by an authorized service center.

CLEANING SAW BODY

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.

WARNING: When cleaning saw body,

¥do not submerge saw in any liquids

¥do not use products that contain am- monia, chlorine, or abrasives

¥do not use chlorinated cleaning sol- vents, carbon tetrachloride, kerosene, or gasoline

Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture. Wipe saw body to clean.

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 19). 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 periodi- cally. Use putty knife or wire (see Figure 20).

3.Clean oil slots after each day of use.

4.Remove burrs from sides of guide bar. Use ßat Þle 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 and Accessories, page 21, for proper bar.

SHARPENING 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, hard- ware store, or chain saw supplies outlet.

¥5/32" round Þle

¥Depth gauge tool

¥File guide

¥Vise

¥Medium sized ßat Þle

Sharpening Cutters

Use Þle guide for 30° Þling.

1.Adjust chain for proper tension (see Saw Chain Tension Adjustment, pages 16 and 17).

2.Clamp guide bar in vise to hold saw steady. Note: Do not clamp chain.

3.Press 5/32" round Þle (attached to Þle guide) into groove between top plate and depth gauge on chain. File guide should rest on both top plate and depth gauge (see Figure 21). Note: File at midpoint of guide bar.
