Operating Tips

• While vacuuming or blowing debris, hold the unit with the muffler side facing away from your body and clothes.
• To reduce the risk of hearing loss associated with sound level(s), hearing protection is required.
• To reduce the risk of injury associated with contacting rotating parts, stop the engine before installing or removing attachments. Do not operate without guard(s) in place.
• Operate power equipment only at reasonable hours—not early in the morning or late at night when people might be disturbed. Comply with times listed in local ordinances. Usual recommendations are 9:00 a.m. to 5:00 p.m., Monday though Saturday.
• To reduce noise levels, limit the number of pieces of equipment used at any one time.
• To reduce noise levels, operate power blowers at the lowest possible throttle speed to do the job.
• Use rakes and brooms to loosen debris before blowing.
• In dusty conditions, slightly dampen surfaces when water is available.
• Conserve water by using power blowers instead of hoses for many lawn and garden applications, including areas such as gutters, screens, patios, grills, porches, and gardens.
• Watch out for children, pets, open windows, or freshly washed cars. Blow debris away safely.
• Use the full blower nozzle extension so the air stream can work close to the ground.
• After using blowers and other equipment, CLEAN UP! Dispose of debris in trash receptacles.

Holding the Unit

Diagram Description: Figure 8 shows the correct way to hold the unit, in front of the body, and the incorrect way, at the side, which can lead to burns from the hot engine.

• Stand in the operating position (Fig. 8). Stand up straight. Do not bend over.
• Keep feet apart and firmly planted.
• Hold the unit in front of, and away from, your body (Fig. 8).

❗ WARNING: To prevent serious personal injury or damage to the unit, DO NOT hold the unit at your side (Fig. 8). The engine may be extremely hot. DO NOT block the air intake.

❗ WARNING: To avoid serious personal injury, always stop the engine and allow it to cool before cleaning or maintaining the unit. Never perform cleaning or maintenance while the unit is running. Disconnect the spark plug wire ? to prevent the unit from starting accidentally.

❗ WARNING: Wear protective clothing and observe all safety instructions to prevent serious personal injury.

❗ WARNING: OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY. Check the oil level before each use. The importance of maintaining the proper oil level cannot be overemphasized.

Diagram Description: Figure 9 shows the oil fill plug and O-ring. Figure 10 illustrates the correct oil level visible on the first thread of the oil reservoir.

1. Stop the engine and allow it to cool.
2. Set the unit on a flat, level surface, such as a workbench or table.
