Strings of cells are electrically disconnected within the pack resulting in three batteries with a lower Watt hour (Wh) rating as compared to one battery with a higher Watt hour rating. This increased quantity of three batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries.

The battery label indicates two Watt hour ratings (see example). Depending on how the battery is shipped, the appropriate Watt hour rating must be used to determine the applicable shipping requirements. If utilizing the shipping cap, the pack will be considered 3 batteries at the Watt hour rating indicated for "Shipping". If shipping without the cap or in a tool, the pack will be considered one battery at the Watt hour rating indicated next to "Use".

Example of Use and Shipping Label Marking

USE: 120 Wh Shipping: 3 x 40 Wh

Shipping Watt hour rating indicates 3 x 40 Wh, meaning 3 batteries of 40 Watt hours each. The Use Watt hour rating indicates 120 Watt hour (1 battery implied).

Fuel Gauge Battery Packs (Fig. B)

Some DEWALT battery packs include a fuel gauge which consists of three LED lights that indicate the level of charge remaining in the battery pack.

The fuel gauge is an indication of approximate levels of charge remaining in the battery pack according to the following indicators:

Important Safety Instructions for All Battery Chargers

WARNING: Read all safety warnings and all instructions for the battery pack, charger and appliance. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

• DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are specifically designed to work together.

• These chargers are not intended for any uses other than charging DEWALT rechargeable batteries. Any other uses may result in risk of fire, electric shock or electrocution.

- Do not expose the charger to rain or snow.

- Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord.

• Make sure that the cord is located so that it will not be stepped on, tripped over or otherwise subjected to damage or stress.

- Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock or electrocution.

- When operating a charger outdoors, always provide a dry location and use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

- 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 size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

Minimum Gauge for Cord Sets

Volts		Total Length of Cord in Feet (meters)
120 V 25 (7.6)		50 (15.2) 100 (30.5) 150 (45.7)
240 V 50 (15.2)		100 (30.5) 200 (61.0) 300 (91.4)

Charging

Fully Charged

Hot/Cold Pack Delay*

The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure.

The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light or by displaying a problem pack or charger blink pattern.

NOTE: This could also mean a problem with a charger. If the charger indicates a problem, take the charger and battery pack to be tested at an authorized service center.

Hot/Cold Pack Delay

When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.

A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate

English

throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.

The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled.

Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System

Li-Ion appliances are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge.

The appliance will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium-ion battery pack on the charger until it is fully charged.

Wall Mounting

These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1" (25.4 mm) long, with a screw head diameter of 0.28–0.35" (7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32" (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions.

fig. H minimum 24 inches (610 mm)

Bump Feed Trimmer Line Feed

Your trimmer uses 0.080 inches (2.032 mm) diameter nylon line. Cutting line will wear faster and require more feeding if the cutting is done along sidewalks or other abrasive surfaces or heavier weeds are being cut.

As you use the trimmer, the string will get shorter due to wear. Gently bump the trimmer on the ground while running at normal speed and the line will feed.

NOTE: Extending nylon line beyond the 13 inch (330 mm) swath will negatively affect performance, runtime, and the life of the trimmer due to potential of damaging motor. Doing so may void the warranty.

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 (FIG. I)

WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

CANTION: To avoid appliance damage, if the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade.

1. Remove battery.
2. Turn spool 21 clockwise to unlock as shown in figure J. The white nub 22 (figure M) inside the spool will rotate away from the spool window 23 to indicate it is unlocked.

1. Pull the spool straight out to remove.
2. Remove any dirt and grass from the spool and housing.
3. First, wind new line in the channel of the spool closest to the holding slots 24 as shown in figure K.
4. Place the end of the cutting line 25 into the retaining hole 26.

1. Wind the cutting line onto the spool in the direction of the arrow on the bottom of the spool. Make sure to wind the line on neatly and in layers. Do not crisscross (figure L).
2. When the wound cutting line reaches the beginning of the holding slots 24, cut the line approximately 4 inches (106 mm).
3. Push the line in the holding slots on one side of the spool to hold the first line while you wind the second line.
4. Repeat the above procedure for the second cutting line on the lower section of the spool.

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 as shown in figure L.

1. Once both lines are wrapped around the spool 23, place your thumb and finger on the holding slots to further secure the string and feed the end of each line through the two holes 27 on either side of the head in the spool housing 11 as shown in figure M.

English

1. Line up the white nubs 22 inside the spool housing with the recesses 28 of the spool. Align the holding slots 24 with the two holes 27 as close as possible.
2. Push the spool into the spool housing and turn counterclockwise to lock the spool in place. Ensure the white nub 22 appears in the spool window 21. Make sure the line doesn't unravel and wrap around the shaft below the spool.
3. Pull both ends of the cutting line to release them from the holding slots. If the line extends past the cutting blade on the guard cut the line so it just reaches the blade.
