[. . . ] If this should happen: Stop the engine. Depress the button on the shaft; twist and pull the shafts to separate the pruner from the power head. If the limb can be reached from the ground, lift the limb while holding the attachment. This should release the "pinch" and free the pruner. If the pruner is still trapped, call a professional for assistance. LIMBING AND PRUNING See Figures 8 - 9. This unit is designed for trimming small branches and limbs up to 6 in. For best results, observe the following precautions. Be aware of the direction in which the branch will fall. Branches may fall in unexpected directions. Do not stand directly under the branch being cut. The most typical cutting application is to position the unit at an angle of 60° or less, depending on the specific situation, as shown below. Refer to Replacing the Bar and Chain for additional information. NOTE: A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug, but it can be turned by hand without binding. Chain must be re-tensioned whenever the flats on the drive links hang out of the bar groove as shown in fig. During normal operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately . 050 in. (1. 25 mm) out of the bar groove, as shown in fig. NOTE: New chain tends to stretch; check chain tension frequently and tension as required. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. WARNING: Before inspecting, cleaning or servicing the unit (except for carburetor adjustments), shut off engine, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage. CAUTION: Chain tensioned while warm, may be too tight upon cooling. Check the "cold tension" before next use. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. [. . . ] The 1995 and later small off-road engines are warranted for two years in California. In all other states for 1997 and later model years, EPA requires manufacturers to warrant non-road engines for two years. These warranty periods will begin on the date the non-road or small off-road engine is purchased by the initial purchaser. If any emission-related part on your engine is defective, the part will be replaced by Techtronic Industries North America, Inc. , at no cost to the owner. [. . . ]
