Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or other serious injury. When operating unit, stand as shown and check for the following: • Wear eye protection, hearing protection and heavy clothing. • Hold trigger handle with right hand and assist handle with left hand. • Hold unit so that engine is below waist level. • Cut only from your left to your right to ensure debris is thrown away from you. Without bending over, keep line near and parallel to the ground and not crowded into material being cut. Do not run the engine at a higher speed than necessary. The cutting line will cut efficiently when the engine is run at less than full throttle. At lower speeds, there is less engine noise and vibration. 12 Always release thethrottle trigger and allow theengine toreturn toidle speed whennotcutting. HOW TO STOP YOUR UNIT • Release the throttle trigger. • Move the ON/OFF switch to the OFF position. CUTTING METHODS ,i_WARNING: Use minimum speed and do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), which can damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard. • The tip of the line does the cutting. You will achieve the best performance and minimum line wear by not crowding the line into the cutting area. The right and wrong ways are shown below. Tip of line does the Line crowded into SCALPING - The scalping technique removes unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 3 inches (8 cm) above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique increases line wear. Scalping MOWING - Your trimmer is ideal for mowing in places conventional lawn mowers cannot reach. In the mowing position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool. wor__ Mowing Right Wrong • The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fences. • For trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially: • During light duty cutting. • Near objects around which the line can wrap such as small posts, trees or fence wire. TRIMMING - Hold the bottom of the trimmer head about 3 inches (8 cm) above the ground and at an angle. Allow only the tip of the line to make contact with vegetation. Do not force trimmer line into work area. SWEEPING - The fanning action of the rotating line can be used to blow away loose debris from an area. Keep the line parallel to and above the area surface and swing the tool from side to side. j_ Trimming 3 inches (8 cm) abow ground 13 Sweeping MAINTENANCE SCHEDULE ,_ WARNING: Disconnect the spark plug before performing maintenance except for carburetor adjustments.

CARBURETOR ADJUSTMENT _,WARNING: Keep others away when making idle speed adjustments. The trimmer head will be spinning during most of this procedure. Wear your protective equipment and observe all safety precautions. After making adjustments, the trimmer head must not move or spin at idle speed. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: • Engine will not idle when the throttle is released. • The trimmer head moves or spins at idle. Make adjustments with the unit supported so the cutting attachment is off the ground and will not make contact with any object. Hold the unit by hand while running and making adjustments. Keep all parts of your body away from the cutting attachment and muffler. Idle Speed Adjustment Allow engine to idle. Adjust speed until engine runs without trimmer head moving or spinning (idle too fast) or engine stalling (idle speed too slow). • Turn idle speed screw clockwise to increase engine speed if engine stalls or dies. • Turn idle speed screw counterclockwise to decrease engine speed if trimmer head moves or spins at idle. Cover Air Filter __ Idle Speed Screw '_,WARNING: Recheck the idle speed after each adjustment. The trimmer head must not move or spin at idle speed to avoid serious injury to the operator or others.

Your emission control system includes parts such as the carburetor, the ignition system and the fuel tank (California only). Where a warrantable condition exists, Sears will repair your small off-road engine at no cost to you. Expenses covered under warranty include diagnosis, parts and labor. MANUFACTURER'S WARRANTY COVERAGE: If any emissions related part on your engine (as listed under Emissions Control Warranty Parts List) is defective or a defect in the materials or workmanship of the engine causes the failure of such an emission related part, the part will be repaired or replaced by Sears. OWNER'S WARRANTY RESPONSIBILITIES: As the small off-road engine owner, you are responsible for the performance of the required maintenance listed in your operator's manual. Sears recommends that you retain all receipts covering maintenance on your small off-road engine, but Sears cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance. As the small off-road engine owner, you should be aware that Sears may deny you warranty coverage if your small off-road engine or a part of it has failed due to abuse, neglect, improper maintenance, unapproved modifications, or the use of parts not made or approved by the original equipment manufacturer. You are responsible for presenting your small off-road engine to a Sears authorized repair center as soon as a problem exists. Warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

WARRANTY PERIOD: Any warranted part which is not scheduled for replacement as required maintenance, or which is scheduled only for regular inspection to the effect of "repair or replace as necessary" shall be warranted for 2 years. Any warranted part which is scheduled for replacement as required maintenance shall be warranted for the period of time up to the first scheduled replacement point for that part.
