Safety Rules and Instructions: Extension Cords

WARNING: To reduce the risk of electric shock, use only with an extension cord intended for outdoor use, such as an extension cord of cord type SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A. or SJTOW-A.

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. 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. If the extension will be used outside, the cord must be suitable for outdoor work. The letters "WA" on the cord jacket indicate that the cord is suitable for outdoor use.

- An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is, 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct

Cutting Line / Line Feeding

Your trimmer uses .065 inch (1.65 mm) diameter, ROUND nylon line. During use, the tips of the nylon lines will become frayed and worn and the special self feeding spool will automatically feed and trim a fresh length of line. Cutting line will wear faster and require more feeding if the cutting or edging is done along sidewalks or other abrasive surfaces or heavier weeds are being cut. The advanced automatic line feeding mechanism senses when more cutting line is needed and feeds and trims the correct length of line whenever it's required. Do not bump trimmer on ground in attempt to feed line or for any other purposes.

English

Helpful Cutting Tips

• Use the tip of the string to do the cutting; do not force string head into uncut grass.
• Wire and picket fences cause extra string wear, even breakage. Stone and brick walls, curbs, and wood may wear string rapidly.
• Do not allow spool cap to drag on ground or other surfaces.
• In long growth, cut from the top down and do not exceed 12 inches (304.8 mm) high.
• Keep trimmer tilted toward the area being cut; this is the best cutting area.
• The trimmer cuts when passing the unit from the left to right. This will avoid throwing debris at the operator.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the string.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories.

An accidental start-up can cause injury.

1. Keep the air intake slots clean to avoid overheating.
2. Your trimmer line can dry out over time. To keep your line in top condition, store spare pre-wound spools or bulk line in a plastic, sealable bag with a tablespoon of water.
3. Plastic parts may be cleaned by using a mild soap and a damp rag.
4. The line cutter on the edge of the guard can dull over time. It is recommended you periodically touch-up the sharpness of the blade with a file.

Cleaning

WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing this.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Troubleshooting

Trimmer Runs Slowly

1. Unplug the trimmer.
2. Check that the spool housing can rotate freely. Carefully clean it if necessary.
3. Check that the cutting line does not protrude more than approximately 5-3/8 inches (136mm) from the spool. If it does, cut it off so that it just reaches the line trimming blade.

Automatic Line Feed Does Not Work

1. Unplug the trimmer.
2. Remove the spool cap.
3. Pull the cutting line until it protrudes approximately 5-3/8 inches (136mm) from the spool. If insufficient cutting line is left on the spool, install a new spool of cutting line.
4. Ensure that the line is not crisscrossed on the spool as detailed in Fig. S. If it is, unwind the cutting line, then wind it back on the spool neatly so that the lines do not cross.
5. Ensure the beginning of the cutting line is pulled tight against the spool as shown in Fig. S.
6. Align the tabs on the spool cap with the cut outs in the housing.
7. Push the spool cap onto the housing until it snaps securely into place.
8. If the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade. If the automatic line feed still does not work or the spool is jammed, try the following suggestions:
9. Carefully clean the spool and housing.
10. Remove the spool and check if the lever in the spool housing can move freely.
11. Remove the spool and unwind the cutting line, then wind it on neatly again. Replace the spool into the housing.
