OPERATION WARNING: To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level. Do not force the hedge trimmer through heavy shrubbery. This can cause the blades to bind and slow down. If the blades slow down, reduce the pace. Do not attempt to cut stems or twigs that are larger than 3/8 in. thick, or those obviously too large to feed into the cutting blade. Use a non-powered hand saw or pruning saw to trim large stems. If blades do become jammed, stop the engine or motor, remove the spark plug wire or disconnect from the power supply, allow the blades to stop, and remove the obstruction. If desired, you can use a string to help cut your hedge level. Decide how high you want the hedge. Stretch a piece of string along the hedge at the desired height. Trim the hedge just above the guide line of string. Trim the side of a hedge so that it will be slightly narrower at the top. More of the hedge will be exposed when shaped this way, and it will be more uniform. Always wear gloves when using the hedge trimmer. When trimming new growth, use a wide sweeping action, so that the stems are fed directly into the cutting blade. Older growth will have thicker stems and will be trimmed easiest by using a sawing movement. OPERATING THE HEDGE TRIMMER See Figure 5. WARNING: Read the safety information for safe operation using the blade. Extreme care must be taken when using blades to ensure safe operation. Refer to Specific Safety Rules. Always hold hedge trimmer with both hands when operating. Use a firm grip on the handles. The unit is used for cutting in either direction in a slow, sweeping action from side to side. The hedge trimmer should be positioned so that your body will not come into contact with the muffler on the power head.Stand so that you are stable and balanced on both feet. Inspect and clear the area of any hidden objects. Never use the hedge trimmer near power lines, fencing, posts, buildings, or other immovable objects. Never use a blade after hitting a hard object with- out first inspecting it for damage. Do not use if any damage is detected.
