STARTING AND STOPPING INSTRUCTIONS STARTING INSTRUCTIONS WARNING: Operate this unit in a well-ventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area. WARNING: Avoid accidental starting. Make sure you are in the starting position when pulling the starter rope (Fig. 8). To avoid serious injury, the operator and unit must be in a stable position while starting. 1. Mix fuel with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel Mixing Instructions. 2. Fill the fuel tank with fresh, clean fuel mix. Refer to Fueling the Unit. NOTE: There is no need to turn the unit on. The On/Off Control is in the ON ( I ) position at all times (Fig. 6). 3. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel should be visible in the primer bulb and fuel lines (Fig. 7). If fuel can not be seen in the bulb, press and release the bulb until fuel is visible. 4. Place the choke lever in Position 1 (Fig. 7). 5. Crouch in the starting position (Fig. 8). Squeeze the throttle control lever. Pull the starter rope 5 times. Choke Lever 6. Place the choke lever in Position 2 (Fig. 7) 7. Squeeze the throttle control, pull the starter rope in a controlled motion 3 to 5 times to start engine. 8. Keep the throttle squeezed and allow the engine to warm up for 30 to 60 seconds. 9. Continue squeezing the throttle control, move the choke lever to Position 3 (Fig. 7) and continue warming the engine for an additional 60 seconds. The unit may be used during this time. NOTE: Unit is properly warmed up when engine accelerates without hesitation. IF...the engine hesitates, return the choke lever to Position 2 (Fig. 7) and continue warm-up. Fig. 7 IF...the engine does not start, go back to step 3. IF...the engine fails to start after 2 attempts, place the choke lever in Position 3 and squeeze the throttle control. Pull the starter rope out with a controlled and steady motion 3 to 8 times. The engine should start. If not, repeat. IF WARM...If the engine is already warm, go back to step 6. Starter Rope STOPPING INSTRUCTIONS 1. Release the throttle control and allow the engine to cool down by idling. 2. Press and hold the On/Off Control switch in the OFF (O) position until the unit comes to a complete stop (Fig. 6).

Continue to squeeze the throttle control, remove the electric starter or drill from the unit and allow the engine to warm up for 30 to 60 seconds. 10.Continue squeezing the throttle control, move the choke lever to Position 3 (Fig. 7) and run the unit for an additional 60 seconds. The unit may be used during this time NOTE: Unit is properly warmed up when engine accelerates without hesitation. IF...the engine hesitates, return the choke lever to Position 2 (Fig. 7) and continue warm-up. IF...the engine does not start, go back to step 3. IF...the engine fails to start after 2 attempts, place the choke lever in Position 3 and squeeze the throttle control. Press and hold the electric starter or drill ON (I) button for 2-second intervals until the unit starts. IF WARM...If the engine is already warm, start the unit with the blue choker lever in Position 2. After the unit starts, move the blue choker lever to Position 3. STOPPING INSTRUCTIONS 1. Release the throttle control and allow the engine to cool down by idling. 2. Press and hold the On/Off Control switch in the OFF (O) position until the unit comes to a complete stop (Fig. 6). OPERATING INSTRUCTIONS HOLDING THE UNIT WARNING: Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit. Before operating the unit, stand in the operating position (Fig. 9). Check for the following: • The operator is wearing eye protection and proper clothing • With a slightly-bent right arm, the operator's hand is holding the shaft grip Fig. 9 • The operator's left arm is straight, the left hand holding the D-handle • The unit is at waist level • The cutting head is parallel to the ground and easily contacts the grass without the need to bend over ADJUSTING TRIMMING LINE LENGTH WARNING: Do not remove or alter the line cutting blade assembly. Excessive line length will cause premature engine failure and / or unit damage. The Bump Head™ cutting head allows the release of trimming line without stopping the engine. To release more line, lightly tap the cutting head on the ground (Fig. 10) while operating the unit at high speed. NOTE: Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter. Each time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in the cutting head shield will cut the line to the proper length if any excess line is released. For best results, tap the bump knob on bare ground or hard soil. If attempting a line release in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter. NOTE: Do not rest the Bump Head™ on the ground while the unit is running. Fig. 10 Some line breakage will occur from: • Entanglement with foreign matter • Normal line fatigue • Attempting to cut thick, stalky weeds • Forcing the line into objects such as walls or fence posts TIPS FOR BEST TRIMMING RESULTS • Keep the cutting head parallel to the ground. • Do not force the cutting head. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine. • Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag. • Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown away from the operator. • Slowly move the unit into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side motion. Cutting shorter lengths produces the best results. • Trim only when grass and weeds are dry. • The life of the cutting line is dependent upon: • Following the trimming techniques • What vegetation is being cut • Where vegetation is cut For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree. 30° DECORATIVE TRIMMING Decorative trimming is accomplished by removing all vegetation around trees, posts, fences, etc.. Fig. 11 Rotate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 11). MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE SCHEDULE WARNING: To prevent serious injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start. Perform these required maintenance procedures at the frequency stated in the table.
