• Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the state of California to cause cancer, birth defects, or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks, cement, and other masonry products
• Arsenic and chromium from chemically-treated lumber
• Your risk from these exposures varies, depending upon how often you do this type of work.
• To reduce your exposure to these chemicals:
• Work in a well-ventilated area.
• Work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth or eyes or to lie on the skin may promote absorption of harmful chemicals.

A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless indicated elsewhere in this manual.
• Do not charge the battery pack in rain, or in wet locations.
• Prevent unintentional starting. Ensure the switch is in the “off” position before connecting to battery pack, picking up or carrying the appliance. Carrying the appliance with your finger on the switch or energizing appliance that have the switch on invites accidents.
• Disconnect the battery pack from the appliance before making any adjustments, changing accessories, or storing appliance. Such preventive safety measures reduce the risk of starting the appliance accidentally.
• Use the battery operated blower only with specifically designated battery pack. Use of any other batteries may create a risk of fire.
• Use only with the battery packs and chargers listed below:

• Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire explosion or risk of
  injury.

• Do not expose a battery pack or appliance to fire or excessive temperature. Exposure  to fire or temperature above 130°C may cause explosion.

• Follow all charging instructions and do not charge the battery pack or applianceoutside of the temperature range specified in the instructions. Charging improperly or
  at temperatures outside of the specified range may damage the battery and increase the risk of fire.

• Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.

• Do not modify or attempt to repair the appliance or the battery pack except as indicated in the instructions for use and care.

• Do not dispose of the battery in a fire. The cells may explode. Check with local codes for possible special disposal instructions.

• Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.

• Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and
  cause burns.

• Do not operate the trimmer while under the influence of alcohol or drugs.

• Clear the area to be cut before each use. Remove all objects such as rocks, broken glass, nails, wire, or string that can be thrown or become entangled in the cutting attachment. Make sure that other persons and pets are at least 100 ft. (30.5m) away.

• Always hold the trimmer firmly, with both hands on the handles, while operating. Wrap your fingers and thumbs around the handles.

• To reduce the risk of injury from loss of control, never work on a ladder or on any other insecure support. Never hold the cutting attachment above waist height.

• Do not operate the trimmer in gaseous or explosive atmospheres. Motors in these appliances normally spark, and the sparks might ignite fumes.

• Wear heavy long pants, long sleeves, boots, and gloves. Avoid loose garments or jewelry that could get caught in moving parts of the machine or its motor.

• Damage to trimmer – If you strike a foreign object with the trimmer or it becomes entangled, stop the tool immediately, check for damage and have any damage repaired before further operation is attempted. Do not operate with a broken guard or spool.

• If the equipment should start to vibrate abnormally, stop the motor and check immediately for the cause. Vibration is generally a warning of trouble.

• A loose head may vibrate, crack, break or come off the trimmer, which may result in serious or fatal injury. Make sure that the cutting attachment is properly fixed in position. If the head loosens after fixing it in position, replace it immediately.

• Never use a trimmer with a loose cutting attachment.

• Replace a cracked, damaged or worn-out cutting head immediately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.

• Check the cutting attachment at regular short intervals during operation, or immediately if there is a noticeable change in cutting behavior.

• When replacing the cutting line, use triangle-shaped twisted nylon cutting line with a size that does not exceed 0.08 in. (2.0 mm); using heavier lines than recommended by the manufacturer increases the load on the motor and reduces its operating speed. This results in overheating and damage to the trimmer.

• To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.

• When servicing, use only identical replacement parts. Use of any other accessory or attachment which is not recommended for use with this tool may increase the risk of injury.

• Do not wash with a hose; avoid getting water in motor and electrical connections.

• Save these instructions. Refer to them frequently and use them to instruct others who may use this tool. If you lend this tool to someone else, also lend these instructions to them to prevent misuse of the product and possible injury.

OPERATING INSTRUCTIONS

Using the String Trimmer Check for damaged/worn parts before each use

To prevent serious personal injury, remove the battery pack from the tool before servicing, cleaning, changing attachments or removing material from the unit. Check the bump head, guard (K) and front-assist handle (H) and replace any parts that are cracked, warped, bent, or damaged in any away. The line- cutting blade (L) on the edge of the guard can dull over time. It is recommended that you periodically sharpen it with a file or replace it with a new blade.

Always wear gloves when mounting or replacing the guard or when sharpening or replacing the blade. Note the location of the blade on the guard and protect your hand from injury.

Tips for best trimming results

• To avoid serious personal injury, wear goggles or safety glasses at all times when operating this unit. Wear a face mask or dust mask in dusty locations. Wear proper clothing and footwear during operation to reduce the risk of injury that may be caused by flying debris.
• Clear the area to be cut before each use. Remove all objects, such as rocks, broken glass, nails, wire, or string that can be thrown or become entangled in the cutting attachment. Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders and pets at least 100 ft. (30.5 m) away; there still may be risk to bystanders from thrown objects.
• Bystanders should be encouraged to wear eye protection. If you are approached, stop the motor and cutting attachment immediately. The correct angle for the cutting attachment is parallel to the ground.
• This string trimmer allows you to rest the bump knob (G) on the ground for more comfortable operation.
• Do not force the trimmer. Allow the very tip of the line to do the cutting (especially along walls). Cutting with more than the tip will reduce cutting efficiency and may overload the motor.
• The cutting height is determined by the distance of the cutting line from the lawn surface.
• Grass over 8 in. (200 mm) should be cut by working from top to the bottom in small increments to avoid premature line wear or motor drag.
• Slowly move the trimmer into and out of the area being cut, maintaining the cutting head position at the desired cutting height. This movement can be either a forward-backward motion or a side-to-side motion. Cutting shorter lengths produces best results.
• Trim only when grass and weeds are dry.
• Wire and picket fences can cause extra string wear or breakage. Stone and brick walls, curbs, and wood may wear strings rapidly.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the strings.

Adjusting Cutting Line Length (Fig 7b)

The trimmer head allows the operator to release more cutting line without stopping the motor. As line becomes frayed or worn, additional line can be released by lightly tapping the bump knob (G) on the ground while operating the trimmer. For best results, tap the bump knob on bare ground or hard soil. If line release is attempted in tall grass, the motor may overheat. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

WARNING

• Do not remove or alter the line cutting blade assembly. Excessive line length will cause the motor to overheat and may result in serious personal injury.
• To prevent serious personal injury, remove the battery pack from the tool before servicing, cleaning, changing attachments or removing material from the unit.
• Clear any grass that may have wrapped itself around the motor shaft or trimmer head.
• Use only a clean, dry and soft cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
• Keep the air vents in the rear housing free from debris at all times.

NOTICE: Obstructing the vents will prevent the air from flowing into the motor housing and may result in overheating or damage to the motor.

Never use water for cleaning your trimmer. Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents. Use clean clothes to remove dirt, dust, oil, grease, etc.

Line Replacement

NOTICE: Always use triangle-shaped twisted nylon cutting line with a size that does not exceed 0.08 in. (2.0 mm). Using line other than that specified may cause the string trimmer to overheat or become damaged.

WARNING
Never use metal-reinforced line, wire, or rope, etc. These can break off and become dangerous projectiles.

Wind the spool with new line

To prevent serious personal injury, remove the battery pack from the tool before servicing, cleaning, changing attachments or removing material from the unit.

• Press the two release tabs on the spool base and remove the spool retainer by pulling it straight out (Fig. 8a).
• Remove the spool. Use a clean cloth to clean the inner surface of the spool retainer and spool base.

NOTICE: Always clean the spool retainer and spool base before reassembling the trimmer head.

• Check the spool retainer, spool and spool base worn wear parts.
• Take approximately 15 ft. (4.5 m) of 0.08 in. (2.0 mm) diameter cutting line. Fold the line in half and then adjust it so that one end is 4.5 in. (11 cm) longer than the other (Fig. 8b).
• Hook the folded end of the cutting line onto either of the slots in the spool.
• Wind the line, in two even and tight layers, onto the spool. Wind the line in the direction indicated on the spool.

NOTICE: Failure to wind the line in the direction indicated will cause the trimmer head to operate incorrectly.Place the ends of the line in two opposite notches in the spool, with approximately 5 in. (12.5 cm) protruding (Fig. 8c).

• Align the notches of the spool from which the lines protrude with the eyelets in the spool retainer and position the spool in the retainer (Fig.8d).
• Holding the spool and spool retainer, grasp one end of the line and pull it to release the line from the notch in the eyelet (Fig. 8e). Repeat with the other end.
• With the spool base facing downward, align the slots in the spool retainer with the tabs on the spool base and press the retainer evenly down until it snaps into place (Fig. 8f).

NOTICE: Make sure that the tabs on the spool base snap into place or the spool will come out during operation.

CARE AND MAINTENANCE

All maintenance should only be carried out by a qualified service technician. Before cleaning or performing any maintenance, remove battery from the tool. For safe and proper operation, always keep the tool and its ventilation slots clean. Cleaning Always use only a soft, dry cloth to clean your string trimmer; never use detergent or alcohol. Clear any grass that may have wrapped itself around the motor shaft or trimmer head. Keep the air vents free of obstructions. Storage Clean the tool thoroughly before storing it.
