PROPER GRIP ON HANDLE
• Always maintain a proper grip on the handles whenever
the motor is running. Grip the unit firmly with both
hands. Keep the left hand on the D-handle and the right
hand on the shaft grip. The fingers should encircle the
handle(s) and the thumb(s) should wrap under the
handle(s). The left arm should be straight and the right
arm slightly bent.
PROPER STANCE
• Balance body weight securely, with both feet on solid
ground.
WORK AREA PRECAUTIONS
• Keep everyone – helpers, bystanders, children and animals – at least 50 feet (15 m) away from the
work area. If anyone enters the work area, stop the unit!
• Only operate the unit when visibility and light are adequate to see clearly.
• Remove stones, nails, glass and wire from the area before operating the unit.
• Only operate the unit during reasonable hours. Comply with times listed in local ordinances.
OPERATING THE TRIMMER
1. Hold the unit at waist level with the cutting head parallel to the ground so that it easily contacts the
grass without the need to bend over (Fig. 11).
2. Start the motor. Refer to Starting and Stopping Instructions.
3. Slowly move the cutting head into and out of the cutting area at the desired height.
• Move either in a forward-backward or side-to-side motion. When cutting from side-to-side, cut
from left to right whenever possible. This improves the unit’s cutting efficiency and directs
clippings away from the operator.
• Cutting shorter lengths produces the best results.
• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid
premature blade wear or motor drag.
• Do not force the cutting head. Allow the tip of the blade to do the cutting, especially along
walls. Cutting with more than the tip will reduce cutting efficiency and may overload the motor.
• Use the throttle speed(s) recommended for the Vegetation Task, as listed below:
• Only trim when grass or weeds are dry.
4. Dispose of debris appropriately.
Decorative Trimming
Decorative trimming is the act of removing all vegetation
from around trees, posts, fences, etc. To accomplish it,
rotate the whole unit so that the cutting head is at a 30˚
angle to the ground (Fig. 12).
Cutting Blades
The cutting blades wear down and becomes shorter with
use. The life of the cutting blades is dependent upon:
• Following the trimming techniques previously
explained
• What vegetation is cut
• Where the vegetation is cut.
For example, the cutting blades will wear faster when trimming against a foundation wall as opposed
to trimming around a tree.
Some blade breakage may occur from:
• Entanglement with foreign matter
• Normal blade fatigue
• Attempting to cut thick or stalky weeds
• Forcing the blades into objects such as walls or fence posts
NOTE: Replace all cutting blades when the cutting performance becomes poor.

WARNING: If blade breakage occurs, replace all blades immediately, as the unit may
become unstable and difficult to control, resulting in personal injury.
CHARGING THE BATTERY
NOTE: The battery is not shipped fully charged. It is
recommended to fully charge the battery before use to
ensure that maximum run time can be achieved. The
lithium-ion battery will not develop a memory and may
be charged at any time. A fully discharged battery will
require approximately 1-2 hours to completely charge.
1. Plug the charger into an AC wall outlet/receptacle.
2. The red Power LED will illuminate (Fig. 6).
3. Insert the battery into the charger (Fig. 7).
NOTE: Make sure the battery is fully inserted into the
charge by making sure the red Indicator LED charge
light is on (Fig. 6).
4. Once the battery has reached a full charge level the
Indicator LED will turn from red to green (Fig. 6).
5. The battery may be removed or stored in the charger
once it is fully charged; however, it is recommended to
disconnect the plug from the wall outlet/receptacle. To
remove the battery, hold down the battery latch and
slide the battery off the charger (Fig. 7).
NOTE: Lithium-ion batteries, while in use, will continue to
provide full power without power fade unlike typical
batteries; when the battery is fully discharged, the
battery circuitry will immediately cut power to the tool
and require immediate charging.
Battery Instructions
Press the battery capacity indicator (BCI) button. The lights will
illuminate according to the battery’s current power level (Fig. 8).
INSTALLING AND REMOVING THE BATTERY
Follow these instructions in order to avoid injury and to
reduce the risk of electric shock or fire:
• Verify that the lock-off button is in the locked or OFF
position before installing or removing the battery. Refer
to Starting and Stopping Instructions.
• Verify that the battery is removed and the lock-off button is
in the locked or OFF position before inspecting, adjusting
or performing maintenance on any part of the unit.
Installing the Battery
1. Align the tongue of the battery with the handle cavity (Fig. 9).
2. Grasp the rear handle firmly.
3. Push the battery into the handle cavity until the latch
locks into place.
4. Do not use force when inserting the battery. It should
slide into position and “click.”
Removing the Battery
1. Press the latch button on the battery down and hold (Fig. 9).
2. Grasp the rear handle firmly and pull the battery out of the handle cavity.
NOTE: The battery fits into the handle cavity snugly in order to prevent accidental dislodging. It may
require a strong pull to remove it.
IMPORTANT! The battery is equipped with an internal circuit breaker that will automatically shut off
power to the unit if the battery is overloaded during heavy use. Once cooled, the battery will reset
itself. Follow these steps if an overload occurs:
1. Release the switch trigger and then restart the unit. Refer to Starting and Stopping Instructions.
2. The battery may need to be removed for approximately 1 minute, allowed to cool and then reinstalled.
STARTING AND STOPPING INSTRUCTIONS
STARTING THE MOTOR
Make sure the immediate area is clear of any objects or
obstructions that could come in contact with the cutting head.
To help prevent accidental start-ups, this unit has a lock-off
button and switch trigger that must be used together to
start the unit.
1. Fit the battery into the handle cavity (Fig. 9). Refer to
Installing the Battery.
2. Press and hold the lock-off button (Fig. 10). This makes
the switch trigger operational.
3. While holding the lock-off button, press and hold the
switch trigger (Fig. 10).
4. Release the lock-off button and continue to squeeze the switch trigger for continued operation.
STOPPING THE MOTOR
1. Release the switch trigger.
NOTE: Upon release of the switch trigger, the lock-off button will automatically reset to the locked position.
