1. Prevent unintentional starting. Ensure the switch is in the off-position before con-
necting to battery pack, picking up or carrying the tool. Carrying the tool with your
finger on the switch or tool that has the switch on, invites accidents.
2. Disconnect the battery pack from the tool before making any adjustments, changing
accessories, or storing tool. Such preventive safety measures reduce the risk of
starting the tool 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 anoth-
er battery pack.
FOR ALL TOOLS
FOR ALL BATTERY-OPERATED GARDEN-
ING TOOLS
1. Keep guards in place and in good working order.
2. Keep hands and feet away from cutting area.
3. When replacing the cutting line, use no more than 0.065” (1.65mm) nylon line; using
heavier lines than recommended by the manufacturer increases the load on the
motor and reduces its operating speed. This results in overheating and damage to
the trimmer.
4. Clear the area to be cut before each use. Remove all objects such as rocks, broken
glass, nails, wire, or string that can be thrown or become entangled in the cutting
attachment. Make sure that other persons and pets are at least 50 ft. (15m) away.
5. Always hold the trimmer firmly, with both hands on the handles, while operating.
Wrap your fingers and thumbs around the handles.
6. Do not operate the trimmer while under the influence of alcohol or drugs.
7. Do not operate the trimmer in gaseous or explosive atmospheres. Motors in these
tools normally spark, and the sparks might ignite fumes.
4. Use tools only with specifically designated battery packs. Use of any other battery
packs may create a risk of injury and fire.
5. When 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 con-
nection 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 tool 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 tool to fire or excessive temperature. Expo- sure to
fire or temperature above 1266°F may cause explosion.
9. Follow all charging instructions and do not charge the battery pack or tool outside
of the temperature range specified in the instructions. Charging improperly or at
temperatures outside of the specified range may damage the battery and in-
crease the risk of fire.
10. Have servicing performed by a qualified repair person using only identical replace-
ment parts. This will ensure that the safety of the product is maintained.
11. Do not modify or attempt to repair the tool or the battery pack (as applicable) except
as indicated in the instructions for use and care.
ADDITIONAL SAFETY RULES FOR STRING
TRIMMER AND EDGE TRIMMER
8. Damage to Trimmer - If you strike a foreign object with the trimmer or it becomes
entangled, stop the tool immediately, check for damage and have any damage
repaired before further operation is attempted. Do not operate with a broken guard
or spool.
9. If the equipment should start to vibrate abnormally, stop the motor and check imme-
diately for the cause. Vibration is generally a warning of trouble. A loose head may
vibrate, crack, break or come off the trimmer, which may result in serious or fatal
injury. Make sure that the cutting attachment is properly fixed in position. If the head
loosens after fixing it in position, replace it immediately. Never use a trimmer with a
loose cutting attachment.
10. Replace a cracked, damaged or worn-out cutting head immediately, even if damage
is limited to superficial cracks. Such attachments may shatter at high speed and
cause serious or fatal injury.
11. Check the cutting attachment at regular short intervals during operation, or immedi-
ately if there is a noticeable change in cutting behavior.
12. Do not wash with a hose; avoid getting water in motor and electrical connections.
13. To reduce the risk of injury from loss of control, never work on a ladder or on any
other insecure support. Never hold the cutting attachment above waist height.
14. If situations occur that are not covered in this manual, use care and good judgment.
Contact the TOLL-FREE HELPLINE: 1-888-930-8528 for assistance.
1. Do not dismantle, open or shred battery pack.
2. Do not expose battery pack to heat or fire. Avoid storage in direct sunlight. The cells
may explode. Check with local codes for possible special disposal instructions.
3. 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 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.
4. Do not subject battery pack to mechanical shock.
5. Observe the plus (+) and minus (–) marks on the battery back and equipment and
ensure correct use.
