Allowing such contact can result in serious injury. IMPORTANT POINTS S Work slowly, keeping both hands firmly gripped on the pruner. Maintain secure footing and balance. S Plan cut carefully. Check direction branch will fall. S Watch out for springpoles. Springpoles are small size limbs which can catch the chain and whip toward you or pull you off balance. Use extreme caution when cutting small size limbs or slender material. S Watch out for branches immediately behind the branch being pruned. If the chain hits the rear branch, damage to the unit may occur. S Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch or the pruner when the tension in the wood fibers is released. S Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them. S Long branches should be removed in several pieces. PRUNING TECHNIQUE When ready to cut, accelerate to full throttle and apply a light cutting pressure. DO NOT use back and forth sawing action. 9 NOTE: When making the second and third cuts, rest the foot of the pruner against the tree limb that is being cut to prevent whipping of the branch. 1. Make the first cut 6 inches from the tree trunk on the bottom of the limb. Use top of guide bar to make this cut. Cut 1/3 through the diameter of the limb.

MAINTENANCE WARNING: Always stop unit and disconnect spark plug wire (or disconnect powerhead from power source) before performing maintenance. CHECK FOR DAMAGED OR WORN PARTS Contact an authorized service dealer for replacement of damaged or worn parts. S Oil tank - --Discontinue use of pruner attach ment if oil tank shows signs of damage or leaks. CHECK FOR LOOSE FASTENERS AND PARTS S Bar clamp nut S Fasteners INSPECT AND CLEAN UNIT AND DECALS S After each use, inspect complete unit for loose or damaged parts. Clean the unit and decals using a damp cloth with a mild detergent. S Wipe off unit with a clean dry cloth. CHECK CHAIN TENSION WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. Make chain adjustments with lower end supported. Chain tension is very important. Chains stretch during use. This is especially true during the first few times you use your pruner. Always check chain tension each time you use and refuel your unit.

Adjusting Screw - --1/4 Turn 4. Using a screwdriver, roll chain around guide bar to ensure all links are in bar groove. 5. Lift up tip of guide bar to check for sag. Release tip of guide bar, then turn adjusting screw 1/4 turn clockwise. Repeat until sag does not exist. 6. While lifting tip of guide bar, tighten bar clamp nut securely with a wrench. 10 7. Use a screwdriver to move chain around guide bar. 8. If chain does not rotate, it is too tight. Slightly loosen bar clamp nut and loosen chain by turning the adjusting screw 1/4 turn counterclockwise. Retighten bar clamp nut. 9. If chain is too loose, it will sag below the guide bar and needs to be tightened following above procedure. WARNING: DO NOT operate the pruner if the chain is loose. If the pruner 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. BAR MAINTENANCE If your pruner cuts to one side, has to be forced through the cut, or been run with an improper amount of bar lubrication it may be necessary to service your bar. A worn bar will damage your chain and make cutting difficult. After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Move ON/STOP switch to the STOP posi tion and disconnect spark plug (or disconnect powerhead from power source). S Loosen and remove bar clamp nut and chain brake. Remove bar and chain from pruner. S Clean the oil holes and bar groove after each 5 hours of operation.
