Shutting Off the Trimmer

To shut off the trimmer, release both triggers.

Whenever you are not using the trimmer or are transporting the trimmer to or from the work area, remove the battery pack.

Removing the Battery Pack from the Trimmer

Press the battery latch button on the trimmer to release the battery pack, then slide the battery pack out of the trimmer (Figure 10).

Advancing the Line Using the Bump Feed

Run the tool at full throttle.
Tap the bump head on the ground to advance the line. The line advances each time the bump head is tapped.

Note: Do not hold the bump head on the ground while running the trimmer.

Note: The line trimming cut-off blade on the grass deflector cuts the line to the correct length.

Figure 11

Bump head

Note: If the line is worn too short, you may not be able to advance the line by tapping it on the ground. If so, release both triggers and refer to Advancing the Line Manually.

Advancing the Line Manually

Remove the battery pack from the trimmer, then push the bump head while pulling on the trimmer line to manually advance the line (Figure 11).

If pushing the bump head does not advance the line it may be jammed. Remove the bump head cover by pushing in on the tabs on either side of the bump head, remove any debris or tangled line, then snap the bump head cover back into place (Figure 12).

Figure 12

Some parts not shown for clarity

Push in on the tabs to access the line directly.

Operating Tips

Keep the trimmer tilted toward the area being cut; this is the best cutting position.
The string trimmer cuts when you move it from left to right; this helps prevent the trimmer from throwing debris at you.
Use the tip of the line to do the cutting; do not force the trimmer head into uncut grass.
Wire and picket fences, stone and brick walls, curbs, and wood can cause the line to wear rapidly and break.
Avoid trees and shrubs; the line can easily damage tree bark, wood moldings, siding, fence posts, and other soft materials.

Maintenance

After each use of the trimmer, complete the following:

Remove the battery pack from the trimmer.
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.
Wipe or scrape clean the cutting head area any time there is an accumulation of debris.
Inspect the machine, check and tighten all fasteners. If any part is damaged or lost, repair or replace it.
Brush debris away from air intake vents and exhaust on motor housing to prevent the motor from overheating.

Replacing the Line

Use only 2.4 mm (0.095 inch) diameter monofilament line.

Remove the battery pack.
Remove any existing line on the spool by repetitively pressing the bump head while pulling the line out equally from both sides of the bump head.
Using 2.4 mm (0.095 inch) line, cut a piece of line that is no longer than 7.3 m (24 ft).

Important: Do not overload the spool.

Important: Do not use any other gauge or type of line, as this could damage the trimmer.
Press and turn the bottom of the trimmer head in the direction shown by the arrows (clockwise) on the bottom of the bump head until the bottom green marks align with the green marks beneath the eyelets (Figure 14).
Insert 1 end of the line straight into the eyelet and push the line through until it comes out through the eyelet on the other side.

3. Eyelet alignment mark
4. Bottom alignment mark
Important: Do not disassemble the trimmer head.
Pull the line through the eyelets until there is an equal length of line on each side of the trimmer head.
Hold the string trimmer in place with one hand. With your other hand, turn the bottom of the trimmer head in the direction shown by the arrows (clockwise) on the bottom of the bump head to wind the line; leave about 152 mm (6 inches) extending beyond the eyelet on each side.

Replacing the Trimmer Head

Remove the battery pack from the trimmer.
Align the hole in the cup plate with the hole in the trimmer gearcase (Figure 15).
Insert the included metal rod through the cup plate and into the hole in the trimmer gearcase to secure the trimmer head (Figure 15).

Storage

Important: Store the tool, battery pack, and charger only in temperatures that are within the appropriate range; refer to Specifications.

Important: If you are storing the battery pack for the off-season, charge it until 2 or 3 LED indicators turn green on the battery. Do not store a fully charged or fully depleted battery. When you are ready to use the tool again, charge the battery pack until the left indicator light turns green on the charger or all 4 LED indicators turn green on the battery.

Troubleshooting

Perform only the steps described in these instructions. All further inspection, maintenance, and repair work must be performed by an authorized service center or a similarly qualified specialist if you cannot solve the problem yourself.

Always remove the battery from the tool when troubleshooting, inspecting, maintaining, or cleaning the tool.

Problem	Possible Cause	Corrective Action
The tool does not run or does not run continuously.	The battery is not fully installed in the tool. The battery pack is not charged. The battery pack is over or under the appropriate temperature range. There is moisture on the leads of the battery pack. The battery pack is damaged. There is another electrical problem with the tool.	Remove and then replace the battery into the tool, making sure that it is fully installed and latched. Remove the battery pack from the tool and charge it. Move the battery pack to a place where it is dry and the temperature is between 5°C (41°F) and 40°C (104°F). Allow the battery pack to dry or wipe it dry. Replace the battery pack. Contact an Authorized Service Dealer.
The tool does not reach full power or the motor housing is getting hot.	The battery pack charge capacity is too low. The air vents are blocked.	Remove the battery pack from the tool and fully charge the battery pack. Clean the air vents.
The tool is producing excessive vibration or noise.	There is debris under the grass shield or in the bump head housing on the trimmer. The spool is not properly wound.	Clean any debris from under the grass shield or in the bump head housing. Advance the line using the bump head and/or remove the line on the spool and wind the spool again.
The bump head does not advance the line.	The trimmer is out of line. The line is tangled in the bump head housing. There is debris under the grass shield or in the bump head housing on the trimmer.	Add more line to the bump head. Remove the bump head cover and untangle the line. Clean any debris from under the grass shield or in the bump head housing.
The battery pack loses charge quickly.	The battery pack is over or under the appropriate temperature range. The trimmer is overloaded.	Move the battery pack to a place where it is dry and the temperature is between 5°C (41°F) and 40°C (104°F). Trim at a slower pace.
