Be sure the air vents on the battery housing are kept clear for proper ventilation (Fig. 4). Charging Tips for Maximum Performance

• Store and charge the unit where temperatures are between 50˚ F (10˚ C) and 100˚ F (38˚ C). Storing the unit or batteries above 100˚ F (38˚ C) will reduce battery life.

• Storage below 50˚ F (10˚ C) will not reduce battery life, but may require a longer charging time.

• Store the unit on the charging station when not in use. The unit is designed so that the battery cannot be overcharged. NOTE: The charging indicator light will remain lit when the unit is properly installed in the charging station. Temperature Effects on Charging Time

• 50˚ F (10˚ C) to 100˚ F (38˚ C) – Battery will charge within 24 hours.

• 40˚ F (4 ˚C) to 50˚ F (10˚ C) – Battery will require up to 48 hours for a full charge.

• Below 40˚ F (4 ˚C) – Battery will not reach full charge. NOTE: The unit run time will be reduced when the battery is not fully charged. Fig. 4 Charging Station Barrel Connector Fig. 5 Charging Indicator Light

3. Charge the battery until the Charging Indicator Light

on the charger turns from red to green (Fig. 5). NOTE: The unit’s operating time and the life of the battery will be shorten if the unit is not fully charged between uses.

4. Place the unit back on the charging station after

each use. The unit is designed so that the battery cannot be overcharged. If the wall outlet is not working properly, have the wall outlet checked by a qualified electrician. This will help prevent serious personal injury.

Before operating the unit, stand in the operating position and check that:

• The operator is wearing eye protection and proper clothing.

• The operator’s right arm is slightly bent, the right hand holding the housing grip.

• With a straight left arm, the left hand holding the D-handle.

• The unit is at waist level.

• The trimmer bump head is parallel to the ground and easily contacts the material to be cut without the operator having to bend over (Fig. 8). Fig. 8

2. Depress and hold the trigger.

3. Release the lock-off button.

Release the trigger to stop the trimmer.

1. Press and hold the lock-off button in (Fig. 6). This

This unit is equipped with an overload protection switch to prevent overheating damage to the motor. If the switch pops out:

1. Release the trigger and allow the unit to cool for a

2. Press the overload switch to reset. Resume

operation (Fig. 7). If the switch pops again shortly after the first time:

1. Allow the unit to cool for 15 to 30 minutes.

2. After the unit has cooled, press the overload switch

to reset. Resume operation If the switch does not stay in or continues to pop out during operation, take the unit to an authorized service dealer for repair. To prevent serious personal injury, ensure the lock-off button resets each time the trigger is released.

Dress properly to reduce the risk of injury when operating this unit. Do not wear loose clothing or jewelry. Wear eye and ear/hearing protection. Wear heavy, long pants, boots and gloves. Do not wear short pants, sandals or go barefoot.

To prevent serious injury, do not carry the unit with your finger on the trigger.

• Keep the cutting attachment parallel to the ground.

• Do not force the cutting attachment. Allow the 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.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or motor drag.

• Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown away from the operator.

• Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward- backward or side-to-side motion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon:

• Following the trimming techniques previously explained

• What vegetation is cut

• Where vegetation is cut For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree. DECORATIVE TRIMMING Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more. Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 10). NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter. Each time the head is bumped, approximately 1 inch (25.4 mm) of trimming line is released. A blade in the string guard will cut the line if excess line is released. For best results, tap the head 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. Fig. 9 Bump Head

OPERATING THE TRIMMER

Clear the area to be cut before each use. Remove all objects such as rocks, broken glass, nails, wire, or string which 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 outside a 50 feet (15m) radius; there still may be a 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. NOTE: Remove protective tape from the line cut-off blade before operating trimmer.

ADJUSTING TRIMMING LINE LENGTH

The bump head allows the operator to release more trimming line without stopping the motor. As line becomes frayed or worn, additional line can be released by lightly tapping the trimming head on the ground while operating the trimmer (Fig. 9). Fig. 10 Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.

Do not remove or alter the line cutting blade assembly. Excessive line length will make the unit overheat. This may lead to serious personal injury or damage to the unit. CAUTION:11

This unit is double-insulated. In a double-insulated unit, two systems of insulation are provided instead of grounding. There is no grounding provided and no means of grounding should be added to this unit. Extreme care and knowledge of the system is required when servicing a double-insulated unit. Service should be performed by qualified service personnel only. Replacement parts for a double-insulated unit must be identical to the parts they replace. Refer any repair to an authorized service dealer. A double-insulated unit is marked with the words “double insulation” or “double insulated.” LINE INSTALLATION Always use genuine original equipment manufacturer
