GENERAL SAFETY WARNINGS AND INSTRUCTIONS FOR

ALL TOOLS

SAFETY WARNINGS: DOUBLE INSULATION

Double insulated tools are constructed throughout with two separate layers of electrical insulation or one double thickness of insulation between you and the tool’s electrical system. Tools built with this insulation system are not intended to be grounded. As a result, your tool is equipped with a two prong plug which permits you to use extension cords without concern for maintaining a ground connection.

NOTE: Double insulation does not take the place of normal safety precautions when operating this tool. The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool.

Replacement parts: When servicing all tools, USE IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords.

SAFETY WARNINGS AND INSTRUCTIONS: POLARIZED

PLUGS

To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This equipment must be used with a suitable polarized 2 wire or 3 wire extension cord. Polarized connections will fit together only one way. Make sure that the receptacle end of the extension cord has large and small blade slot widths. If the

plug does not fit fully into the extension cord, reverse the plug. If it still does not fit, obtain a suitable extension cord. If the extension cord does not fit fully into the outlet, contact a qualified electrician to install the proper outlet. Do not change the tool plug or extension cord in any way.

of moving parts, binding of moving parts, breakage of parts, mounting, and any other condition that may affect its operation. Aguard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated elsewhere in this manual.

WARNING: When servicing double insulated tools, USE ONLY IDENTICAL REPLACEMENT PARTS. Replace or repair damaged cords.

WARNING: To prevent electrical shock hazard, use only with an extension cord

suitable for outdoor use. Always connect extension cords to a fused line or one protected by a circuit breaker.

WARNING: To reduce the risk of electric shock use only with an extension cord intended for outdoor use, such as SW-A, S0W-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A or SJTOW-A.

• EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord be sure it is heavy enough to carry the current your product will draw. An undersized extension cord will cause a drop in line voltage resulting in loss of power and

overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

ADDITIONAL WARNINGS FOR

STRING TRIMMERS

1. DO NOT immerse tool in water or squirt it with a hose. DO NOT allow any liquid to get inside it.

2. Do not store the tool on or adjacent to fertilizers or chemicals.

3. DO NOT clean with a pressure washer.

through the holes in the handle and thread on the plastic knob as shown in figure 5.

• For maximum comfort and control, adjust the auxiliary handle to suit your height. Shorter users adjust handle to a lower position (away from you) and taller users, adjust handle to an upper position (towards you). The handle should be adjusted so that your front arm is straight when the trimmer is in the working position.

HEIGHT ADJUSTMENT

• The overall height of the trimmer can be adjusted by pressing the conversion button shown in figure 6 and moving the metal tube up or down into one of the three rectangular recesses in the tube until you hear it “snap” into place.

CAUTION: Confirm that the tube is locked in place by releasing the button and pushing down on the tube.

ATTACHING EXTENSION CORD

• An extension cord retainer (figure 7) is built into the switch handle that prevents the cord from coming unplugged. To use this feature, simply double the extension cord about 8 inches (203mm) from the end, and insert it into the slot in the bottom of the handle area. Hook the loop formed by doubling the cord over the tab. Gently tug on the cord to insure that it is firmly retained in the trimmer’s handle. Plug the receptacle end of the extension cord into the plug blades in the trimmer.

OPERATING INSTRUCTIONS

WARNING:

Always use proper eye protection that conforms to ANSI Z87.1 (CAN/CSA Z94.3) while operating this power tool.

CAUTION: Inspect area to be trimmed and remove any wire, cord, or string-like objects which could become entangled in the rotating line or spool. Be particularly careful to avoid any wire which might be bent outwardly into the path of the tool, such as barbs at the base of a chain link fence.

SWITCHING ON AND OFF

• To switch the tool on, squeeze the trigger lever.

• To switch the tool off, release the trigger lever.

• With the unit on, angle unit and slowly swing the trimmer side to side as shown in figure 8.

• To operate as a maintenance edger, unplug the unit from the power source. Push the conversion button and rotate the tube 180° as shown in figure 6. The tool will lock in position. Gently pull the wire edge guide down into place as shown in figure 9 and position the trimmer above the surface as shown in figure 9.

• Return to the trimming position by unplugging the unit from the power source, pushing the conversion button and rotating the tube back 180°. The tool will lock in the trimmer position. When using the tool return the wire edge guide to the original position, out of the way.

BLOWER FUNCTION (FIGURE 10)

The air flow created by the motor funnels up through the guard to provide a built-in blower. This feature can be used to blow grass clippings off of sidewalks and other hard surface areas.

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 line hub 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 unit on ground in attempt to feed line or for any other purposes.

FITTING A NEW SPOOL OF AFS CUTTING LINE (FIGURES 11 & 12)

• Unplug the tool.

• Depress the tabs (a) and remove the cassette (b) from the cassette housing (c) in the trimmer head (figure 11).

• Grasp empty spool (d) with one hand and cassette with other hand and pull spool out from cassette. If lever (e) in base of cassette becomes dislodged, replace in correct position before inserting new spool into cassette.

• Remove any dirt and grass from the cassette and housing.

• Take the new spool and push it onto the boss (f) (figure 12) in the cassette. Rotate the spool slightly until it is seated.

• Unfasten the end of one of the cutting lines and guide the line into one of the eyelets (g) (figure 12). The line should protrude approximately 4-3/8 inches (111mm) from the cassette.

• Unfasten the end of the other cutting line and guide the line into the other eyelet. The line should protrude approximately 4-3/8 inches (111mm) from the cassette.

• Align the cassette tabs (a) with the slots (h) in the housing (figure 11).

• Push the cassette onto the housing until it snaps securely into place.

CAUTION: To avoid tool damage, If the cutting lines protrude beyond the

trimming blade (i), cut them off so that they just reach the blade (figure 11).

WINDING NEW LINE ONTO AN EMPTY SPOOL (FIGURES 13 &14)

You may wind new cutting line onto an empty spool. Replacement packs of .065 inch (1.65 mm) cutting line are available from your Sears store.

• Remove the empty spool from the tool as described in “FITTING A NEW SPOOL OF AFS CUTTING LINE”.

• Remove any remaining cutting line from the spool.

• First wind new line onto the uppermost part of the spool.

- Feed 3/4 inch (19mm) of cutting line into one of the line anchoring slots.

- Wind the cutting line onto the spool in the direction of the arrow on the spool. Make sure to wind the line neatly and in layers. Do not crisscross (figure 13).

- When the wound cutting line reaches

the recesses (j), cut the line. (figure 14).

- Temporarily park the line in the holding slots (k) on one side of the spool as shown in the inset in figure 14.

• Repeat the above procedure for the second cutting line on the lower section of the spool.

• Fit the spool onto the tool as described in “FITTING A NEW SPOOL OF CUTTING LINE”.

CAUTION: Before you begin trimming, only use the appropriate type of cutting line. Ensure that cutting line is present in both sections of the spool (figure 12).

IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by a Sears or other qualified service dealer, always using identical replacement parts.

WARNING: To avoid serious injury, switch off and unplug the tool before performing any maintenance.

1. Keep the air intake slots (figure 15)

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.

Use Craftsman replacement spool Model No. 85942.

Reload nylon line (either bulk or prewound replacement spool) as described in this manual.

• USE ONLY .065 inch (1.65 mm)

DIAMETER NYLON MONOFILAMENT LINE. Do not use serrated or heavier gauge line, as they will overload the motor and cause overheating. The unit only functions properly with .065 inch (1.65 mm) diameter nylon monofilament line. This line is available at your local Sears store or other Craftsman outlet.

WARNING: The use of any accessory not recommended by Sears for use with this tool could be hazardous.
