5) Use Safety Glasses – Always use a face or dust mask if the operation is dusty.
6) Use Right Appliance – Do not use an appliance for any job except that for which it is intended.
7) Don’t Force Appliance – It will do the job better and with less likelihood of a risk of injury at the rate for which it was designed.
8) Don’t Overreach – Keep proper footing and balance at all times.
9) Stay alert – Watch what you are doing. Use common sense. Do not operate the appliance when you are tired.
10) Store Idle Appliances Indoors – When not in use, appliances should be stored indoors in dry, and high or locked-up places – out of reach of children.
11) Maintain Appliance With Care – Keep the cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Keep handles dry, clean, and free from oil and grease.
12) Check Damaged Parts – Before further use of the appliance, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other condition that may affect its operation. 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.


  1. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to the battery pack, picking up or carrying the appliance.
    Carrying the appliance with your finger on the switch or energizing appliance that has the switch on invites accidents.
  2. Disconnect the battery pack from the appliance before making any adjustments, changing accessories, or storing the appliance. Such preventive safety measures reduce the risk of starting the appliance accidentally.
  3. Recharge only with the charger specified by the manufacturer.A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  4. Use appliances only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
  5. When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
  6.  Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
  7. 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.
  8. Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause an explosion.
  9. Follow all charging instructions and do not charge the battery pack or appliance outside 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.
  10. Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.
  11. Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as indicated in the instructions for use and care.


  1. Keep guards in place and in good working order.
  2. Keep hands and feet away from the cutting area.
  3. Do not use heavier lines than recommended in this manual.
  4. Do not use line materials of other types – for example, metal wire, rope, and the like.

a) Do not dismantle, open or shred battery pack.
b) Do not expose the battery pack to heat or fire. Avoid storage in direct sunlight.
c) Do not short-circuit a battery pack. Do not store battery packs haphazardly in a box or drawer where they may short-circuit each other or be short-circuited by other metal objects. When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a  connection from one terminal to another. Shorting the battery terminals together may cause burns or fire.
d) Do not remove the battery pack from its original packaging until required for use.
e) Do not subject the battery pack to mechanical shock.
f) In the event of battery leaking, do not allow the liquid to come in contact with the skin or eyes. If contact has been made, wash the affected area with copious amounts of water and seek medical advice.
g) Observe the plus (+) and minus (–) marks on  the battery back and equipment and ensure correct use.
h) Do not use any battery pack which is not designed for use with the equipment.
i) Keep the battery pack out of the reach of children.
j) Seek medical advice immediately if a cell or battery has been swallowed.
k) Always purchase the battery pack recommended by the device manufacturer for the equipment.
l) Keep the battery pack clean and dry.
m) Wipe the battery pack terminals with a  clean dry cloth if they become dirty.
n) Battery pack needs to be charged before use. Always use the correct charger and refer to the manufacturer’s instructions or equipment manual for proper charging instructions.
o) Do not leave the battery pack on prolonged charge when not in use.
p) After extended periods of storage, it may be necessary to charge and discharge the battery pack several times to obtain maximum performance.
q) Battery pack gives its best performance when it is operated at normal room temperature (20 °C ± 5 °C).
r) When disposing of battery packs, keep battery packs of different electrochemical systems separate from each other.
s) Recharge only with the charger specified by WORX. Do not use any charger other than that specifically provided for use with the equipment. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
t) Retain the original product literature for future reference.
u) Use only the battery pack in the application for which it was intended.
v) Remove the battery pack from the equipment when not in use.
w) Dispose of properly.

1. Automatic line feed system
When initially switching on the trimmer, a small length of the line is fed out. Each time the tool is started from rest it will advance about 0.25 inches of trimmer line.
A ‘clattering’ noise will be heard when the lines hit the Line Cutter. DO NOT BE ALARMED. This is quite normal. After about 5 seconds the line will be cut to the correct length and the noise will reduce as the motor gains full speed. If the noise of the line being cut can’t be heard, more lines will need to be fed out. To feed more line, it is first necessary to allow the trimmer to stop completely; it must come to a complete rest, then restart, allowing the motor to reach full speed.  Repeat above until you hear the line hitting against the Line Cutter.
2. Manually feeding the line (See Fig. L) 
Turn off the trimmer and remove the battery. If required, the line can be fed out manually. To operate, press and release the manual Line Feed Button, while gently pulling out the line until it is long enough to reach the Line Cutter. If the line extends past the Line Cutter, too much line has been fed out. If too much line is fed out, remove the Spool Cap and turn Spool counter-clockwise until the line is at the desired length.
3. Manually winding the line (See Fig. N1, N2, N3, N4)
Take approximately 10ft (3m) of line. Insert 5/8 inch (15mm) of line into the Spool holes and wind line in the direction of the arrows on the top of the Spool. Leave approximately 4 inches (100mm) of line unwound and place into the cleat. Ensure that the line is neatly coiled on the Spool. Failure to do so will impair the efficiency of the automatic line feed. Then fit the Spool as shown in Fig. M1, M2, M3


After use, disconnect the battery from the tool and check for damage.
Your power tool requires no additional lubrication or maintenance. There are no user-serviceable parts in your power tool. Never use water or chemical cleaners to clean your power tool. Wipe clean with a dry cloth. Always store your power tool in a dry room temperature location. Keep the motor ventilation slots clean. Keep all working controls free of dust.
For Battery tools
The ambient temperature range for the use and storage of tool and battery is 0 ºC-45 ºC. The recommended ambient temperature range for the charging system during charging is 0 ºC-40 ºC.
