Advancing the Line Manually
Remove the battery pack from the trimmer, then push the bump button at the base of the spool retainer while pulling on the trimmer line to manually advance the line.

Adjusting the Cutting Swath

The trimmer comes from the factory with a cutting swath of 36.6 cm (14 inches) as shown in A of Figure 10.
Refer to the following instructions to adjust the swath to 40.6 cm (16 inches) as shown in D of Figure 10.

1. Remove the swath blade from the bottom of the guard by removing the 2 screws holding it in place using the provided Allen wrench (B of Figure 10) and rotate the swath blade 180°.
2. Once the swath blade is rotated, install it onto the guard using the 2 screws previously removed (C of Figure 10).

Operating Tips

• Keep the trimmer tilted toward the area being cut; this is the best cutting area.
• The string trimmer cuts when you move it from right to left. This prevents the trimmer from throwing debris at you.
• Use the tip of the string to do the cutting; do not force the string head into uncut grass.
• Wire and picket fences can cause the string to wear rapidly and even break. Stone and brick walls, curbs, and wood can also cause the string to wear rapidly.
• Avoid trees and shrubs. The string can easily damage tree bark, wood moldings, siding, and fence posts. 1. Direction of rotation

Maintenance

After each use of the trimmer, complete the following:

1. Remove the battery from the power head.

2. Wipe the trimmer clean with a damp cloth. Do not hose the trimmer down or submerge it in water.
   CAUTION
   The line cutoff blade on the deflector is sharp and can cut you.
   Do not use your hands to clean the deflector shield and blade.

3. Wipe or scrape clean the cutting head area any time there is an accumulation of debris.

4. Check and tighten all fasteners. If any part is damaged or lost, repair or replace it.

5. Brush debris away from air intake vents and exhaust on motor housing to prevent the motor from overheating.

Replacing the String
Important: Use only 2 mm (0.080 inch) diameter monofilament string (Toro Part No. 88611) or 2.4 mm (0.095 inch) diameter twisted monofilament string (Toro Part No. 88202).

1. Remove the battery pack and clean any debris from the trimmer head.

2. Remove any old string on the spool by repetitively pressing the bump button while pulling the line out equally from both sides of the trimmer.

3. Cut a piece of string according to the following specifications.
   • If you are using 2 mm (0.080 inch) string, cut one piece of line approximately 4.9 m (16 ft).
   • If you are using 2.4 mm (0.095 inch) twisted string, cut one piece of line approximately 3 m (10 ft).
   Important: Do not use any other gauge or type of string, and do not exceed the recommended length as this could damage the trimmer.

4. Press and turn the knob on the string head until arrow on the knob aligns with arrow on the string head (Figure 12).

5. Insert 1 end of the line at an angle into the LINE IN eyelet and push the line through the string head track until it comes out through the eyelet on the other side. Pull the line though the string head until the line outside the string is evenly divided on each side. Disassembled view shown for clarity

California Proposition 65 Warning Information

What is this warning?
You may see a product for sale that has a warning label like the following:
WARNING: Cancer and Reproductive Harm—www.p65Warnings.ca.gov.
What is Prop 65?
Prop 65 applies to any company operating in California, selling products in California, or manufacturing products that may be sold in or brought into California. It mandates that the Governor of California maintain and publish a list of chemicals known to cause cancer, birth defects, and/or other reproductive harm. The list, which is updated annually, includes hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to inform the public about exposure to these chemicals.
Prop 65 does not ban the sale of products containing these chemicals but instead requires warnings on any product, product packaging, or literature with the product. Moreover, a Prop 65 warning does not mean that a product is in violation of any product safety standards or requirements. In fact, the California government has clarified that a Prop 65 warning “is not the same as a regulatory decision that a product is ‘safe’ or ‘unsafe.’” Many of these chemicals have been used in everyday products for years without documented harm. For more information, go to https://oag.ca.gov/prop65/faqs-view-all.
A Prop 65 warning means that a company has either (1) evaluated the exposure and has concluded that it exceeds the “no significant risk level”; or (2) has chosen to provide a warning based on its understanding about the presence of a listed chemical without attempting to evaluate the exposure.
Does this law apply everywhere?
Prop 65 warnings are required under California law only. These warnings are seen throughout California in a wide range of settings, including but not limited to restaurants, grocery stores, hotels, schools, and hospitals, and on a wide variety of products. Additionally, some online and mail order retailers provide Prop 65 warnings on their websites or in catalogs.
How do the California warnings compare to federal limits?
Prop 65 standards are often more stringent than federal and international standards. There are various substances that require a Prop 65 warning at levels that are far lower than federal action limits. For example, the Prop 65 standard for warnings for lead is 0.5 μg/day, which is well below the federal and international standards.
Why don’t all similar products carry the warning?

• Products sold in California require Prop 65 labelling while similar products sold elsewhere do not.
• A company involved in a Prop 65 lawsuit reaching a settlement may be required to use Prop 65 warnings for its products, but other companies making similar products may have no such requirement.
• The enforcement of Prop 65 is inconsistent.
• Companies may elect not to provide warnings because they conclude that they are not required to do so under Prop 65; a lack of warnings for a product does not mean that the product is free of listed chemicals at similar levels.

Why does Toro include this warning?
Toro has chosen to provide consumers with as much information as possible so that they can make informed decisions about the products they buy and use. Toro provides warnings in certain cases based on its knowledge of the presence of one or more listed chemicals without evaluating the level of exposure, as not all the listed chemicals provide exposure limit requirements. While the exposure from Toro products may be negligible or well within the “no significant risk” range, out of an abundance of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
