Remove small limbs with one cut. S Keep the tree between you and the chain. S Remove larger branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch the saw. PRUNING WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job. S Make your first cut 1/3 of the way through the bottom of the limb. This cut will make the limb sag so that it falls easily on the second cut. S Next make a second cut all the way through the limb. S Finish the pruning operation by using an overcut so that the stump of the limb protrudes 1 to 2 inches from the trunk of the tree.

To receive full value from the warranty, the operator must maintain unit as instruct-ed in this manual. Various adjustments will need to be made periodically to properly maintain your unit. Improper maintenance may cause damage to the unit and possible injury to the operator or bystanders. 11 CHECK FOR DAMAGED OR WORN PARTS Contact an authorized service dealer for replacement of damaged or worn parts. NOTE: It is normal for a small amount of oil to appear under the saw after motor stops. Do not confuse this with a leaking oil tank. S Trigger Switch - --Ensure the trigger switch functions properly by squeezing and holding the trigger switch. Make sure motor starts and stops. S Oil Tank - --Discontinue use of chain saw if oil tank shows signs of damage or leaks. S Power Cord - --Discontinue use if chain saw power cord shows signs of damage or wear. CHECK FOR LOOSE FASTENERS AND PARTS S Bar Mounting Nut S Chain S Bar Adjusting Screw CHECK CHAIN TENSION WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use your saw. 1. Unplug unit from the power source. 2. Use a screwdriver to move chain around guide bar to ensure kinks do not exist. The chain should rotate freely. NOTE: It is recommended that the saw be turned upside down for chain tensioning. 3. Loosen bar mounting nuts until they are finger tight. 4. Turn the adjusting screw clockwise until the chain solidly contacts bottom of guide bar rail. Then, turn adjusting screw an additional 1/4 turn. This is correct chain tension setting. Adjusting Screw - --1/4 Turn NOTE: To tighten the chain, turn the adjusting screw clockwise; to loosen the chain, turn the adjusting screw counterclockwise. AdjustingScrew 5. Check the tension by lifting the chain from the guide bar. Remove some of the stiffness in the chain by pulling down on the chain several times. 12 6. Continue turning the adjusting screw until the tension is correct (see step 4). 7. Tighten bar mounting nuts with a wrench. 8. Recheck chain tension. WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury. CHECK CHAIN SHARPNESS A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING in the SERVICE AND ADJUSTMENTS section. CHECK GUIDE BAR Conditions which require guide bar maintenance: S Saw cuts to one side or at an angle. S Saw has to be forced through the cut. S Inadequate supply of oil to the bar and chain. Check the condition of the guide bar each time the chain is sharpened. A worn guide bar will damage the chain and make cutting difficult. After each use, with unit disconnected from power source, clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Disconnect the chain saw from the power source. S Loosen and remove bar mounting nuts. Remove bar, bar clamp plate and chain from saw. S Clean the oil holes and bar groove after each 5 hours of operation.
