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. 9 1. Use a screwdriver to move chain around guide bar to ensure kinks do not exist. The chain should rotate freely.

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. 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/OFF switch is in the OFF position, then clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Move ON/OFF switch to the OFF position 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.
