2 Important Safety Instructions

Read and understand all instructions before using this power tool. Failure to follow all instructions may result in electric shock, fire, and/or serious personal injury.

• Use only identical manufacturer's replacement parts and accessories.
• Always wear safety glasses with side shields marked to comply with ANSI Z87.1.
• Avoid dangerous environments; do not expose power tools to damp or wet conditions. Do not use in rain.
• Keep bystanders, children, and pets at least 50 ft. away.
• Dress properly: do not wear loose clothing or jewelry. Use rubber gloves and substantial footwear when working outdoors. Wear protective hair covering for long hair.
• Do not operate the equipment while barefoot or when wearing sandals. Wear protective footwear.
• Use the right appliance for the job.
• Avoid unintentional starting: ensure the switch is off when plugging in the battery.
• Do not force the appliance; it will do the job better and safer at the rate for which it was designed.
• Do not overreach; maintain proper footing and balance.
• Stay alert: use common sense. Do not operate when tired, ill, or under the influence of alcohol, drugs, or medication.
• Always store idle power tools indoors, in a dry, high, or locked-up place, out of reach of children.
• Maintain the appliance with care: replace cracked or chipped parts. Keep the cutting edge sharp and clean. Inspect cords periodically and have them repaired by an authorized service facility. Keep handles dry, clean, and free from oil and grease.
• Check damaged parts before use. A damaged guard or other part should be carefully checked or replaced.
• When servicing, use only identical replacement parts.
• Do not operate cordless tools in damp or wet locations or in the rain.
• Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) used for the gardening appliance.
• Warning: To reduce the risk of electric shock, use only with an extension cord intended for outdoor use (e.g., SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A).
• Disconnect the appliance from the power source before storing, servicing, or changing accessories.
• Do not abuse the cord: never carry the unit by the extension cord or yank the cord to disconnect. Keep the cord clear of the operator and obstacles. Do not expose cords to heat, oil, water, or sharp edges. Do not handle the plug with wet hands.

3 Symbols on the Machine

The following symbols may be used on this machine. Study and learn their meaning for safer operation.

4 Risk Levels

The following signal words and meanings are intended to explain the levels of risk associated with this product.

5 Service

Servicing requires extreme care and knowledge and must be performed only by a qualified service technician. For service, return the machine to your nearest AUTHORIZED SERVICE CENTER for repair. Use only identical manufacturer's replacement parts and accessories.

6 Double Insulated

Double insulation is a safety concept in electric power tools that eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal motor components with protecting insulation. Double insulated tools do not need to be grounded.

WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the tool's internal insulation. Observe all normal safety precautions to avoid electrical shock.

NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. Always use original factory replacement parts when servicing.

7 Extension Cords

When using a power tool at a considerable distance from a power source, use an extension cord that has the capacity to handle the current the product will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required. Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used.

When working outdoors, use an extension cord designed for outdoor use (designated with “W-A” or “W” on the jacket). Inspect the cord for loose or exposed wires and cut or worn insulation before use.

Minimum Gauge for Extension Cords (AWG) (When using 120 V only)

Extension Cord – Ensure your extension cord is in good condition. Use a cord heavy enough to carry the current your product will draw. The table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

To reduce the risk of disconnection of appliance cord from the extension cord during operation:

1. Make a knot as shown in Figure A.
2. Use one of the plug-receptacle retaining straps or connectors.

WARNING: Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury.

8 Proposition 65

WARNING: This product contains a chemical known to the state of California to cause cancer, birth defects or other reproductive harm. Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints;
• Crystalline silica from bricks and cement and other masonry products;
• Arsenic and chromium from chemically treated lumber.

Your risk of exposure to these chemicals varies depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and use approved safety equipment, such as dust masks designed to filter out microscopic particles.
