WARNING:
Some dust created by power sanding, sawing, grinding, drilling
and other construction activities contains chemicals known to the state of California
to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
Lead from lead-based paints
Crystalline silica from bricks and cement and other masonry products, and
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

IMPORTANT SAFETY INSTRUCTIONS
WARNING!
When using electric trimmers, basic safety precautions should
always be followed to reduce the risk of fire, electric shock, and personal injury,
including the following:
READ ALL INSTRUCTIONS
DANGER!
Do not rely on the tool’s insulation against electric shock. To reduce
the risk of electrocution, never operate the tool in the vicinity of any wires or cables
which may carry electric current.
CAUTION!
Wear appropriate personal hearing protection during use. Under some
conditions and durations of use, noise from this product may contribute to hearing loss.
Keep Children Away - All visitors should be kept at least 100 feet away from
work area.
Avoid Dangerous Environments – Don’t use appliances on damp or wet slope.
Dress Properly - Do not wear loose clothing or jewelry. They can be caught in
moving parts. Use of rubber gloves and substantial footwear is recommended
when working outdoors. Wear protective hair covering to contain long hair.
Use Safety Glasses - Always use face or dust mask if operation is dusty.
Use the Right Tool - Do not use the tool for any job except that for which it is
intended.
Don’t Force the Trimmer - It will do the job better and with less likelihood of a
risk of injury at the rate for which it was designed.
Don’t Overreach - Keep proper footing and balance at all times.
Stay Alert - Watch what you are doing. Use common sense. Do not operate the
trimmer when you are tired.
Do not operate the trimmer while under the inuence of alcohol or drugs.
Keep guards in place and in working order.
Keep hands and feet away from the cutting area.
Store Trimmer Indoors - When not in use the trimmer should be stored indoors in a
dry and high or locked-up place with the battery pack removed- out of reach of children.
Maintain Trimmer With Care - Keep the cutting attachment clean for best
performance and to reduce the risk of injury. Follow the instructions for changing
accessories. Keep the handles dry, clean, and free from oil and grease.
56-VOLT LITHIUM-ION CORDLESS 15" STRING TRIMMER 7
Check Damaged Parts - Before further use of the trimmer, 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.
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 100 ft.
(30.5m) away.
Always hold the trimmer rmly, with both hands on the handles, while
operating. Wrap your ngers and thumbs around the handles.
Avoid Accidentally Starting - Don’t carry the trimmer with your finger on
the trigger.
Do not operate the trimmer in gaseous or explosive atmospheres. Motors
in these appliances normally spark, and the sparks might ignite fumes.
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.
If the equipment should start to vibrate abnormally, stop the motor and
check immediately 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.
Replace a cracked, damaged or worn-out cutting head immediately, even
if damage is limited to supercial cracks. Such attachments may shatter at
high speed and cause serious or fatal injury.
Check the cutting attachment at regular short intervals during operation,
or immediately if there is a noticeable change in cutting behavior.
When replacing the cutting line, use no more than 2.4mm 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.
56-VOLT LITHIUM-ION CORDLESS 15" STRING TRIMMER8
To reduce the risk of serious injury, never use wire or metal-reinforced
line or other material in place of the nylon cutting lines. Pieces of wire
could break off and be thrown at high speed toward the operator or bystanders.
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.
If situations occur that are not covered in this manual, use care and
good judgment. Contact the EGO Customer Service Center for assistance.
Do not charge the battery pack in rain, or in wet locations.
Use only with the battery packs and chargers listed below:
BATTERY PACK CHARGER
BA1120, BA1400, BA2240,
BA2800, BA4200
CH5500
CH2100
Do not dispose of the battery in a re. The cells may explode. Check with
local codes for possible special disposal instructions.
Do not open or mutilate the battery. Released electrolyte is corrosive and
may cause damage to the eyes or skin. It may be toxic if swallowed.
Exercise care in handling batteries in order not to short the battery with
conducting materials such as rings, bracelets, and keys. The battery or
conductor may overheat and cause burns.
Replacement Parts - When servicing, use only identical EGO replacement parts.
Use of any other accessory or attachment may increase the risk of injury.
Battery tools do not have to be plugged into an electrical outlet;
therefore, they are always in operating condition. Be aware of possible
hazards even when the tool is not operating. Take care when performing
maintenance or service.
Remove or disconnect battery pack before servicing, cleaning or
removing material from the trimmer.
Do not wash with a hose; avoid getting water in motor and electrical
connections.
Save these instructions. Refer to them frequently and use them to instruct
others who may use this tool. If you lend this tool to someone else, also lend
these instructions to them to prevent misuse of the product and possible injury.

USING THE STRING TRIMMER
WARNING:
To avoid serious personal injury, wear goggles or safety glasses at all
times when operating this unit. Wear a face mask or dust mask in dusty locations.
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. Clear the area of children, bystanders, and pets. At a minimum, keep all
children, bystanders and pets at least 100 feet (30.5m) away; there still may be risk
to bystanders from thrown objects. Bystanders should be encouraged to wear eye
protection. If you are approached, stop the motor immediately.
WARNING:
To prevent serious personal injury, remove the battery pack from the
tool before servicing, cleaning, changing attachments or removing material from the unit.
Check for damaged/worn parts before each use
Check the trimmer head, guard and front-assist handle and replace any parts that are
cracked, warped, bent, or damaged in any away.
The line-cutting blade on the edge of the guard can dull over time. It is recommended
that you periodically sharpen it with a file or replace it with a new blade.
WARNING:
Always wear gloves when mounting or replacing the guard or when
sharpening or replacing the blade. Note the location of the blade on the guard and
protect your hand from injury.
Clean the trimmer after each use
See the Maintenance section for cleaning instructions.
WARNING:
Never use water for cleaning your trimmer. Avoid using solvents
when cleaning plastic parts. Most plastics are susceptible to damage from various
types of commercial solvents. Use clean clothes to remove dirt, dust, oil, grease, etc.
56-VOLT LITHIUM-ION CORDLESS 15" STRING TRIMMER 21
Tips for best trimming results
(Fig. 12)
The correct angle for the cutting
attachment is parallel to the ground.
Do not force the trimmer. Allow the
very tip of the line to do the cutting
(especially along walls). Cutting
with more than the tip will reduce
cutting efficiency and may overload
the motor.
The cutting height is determined by the distance of the cutting line from the lawn
surface.
Grass over 8 inches (200 mm) should be cut by working from top to the bottom in
small increments to avoid premature line wear or motor drag.
Slowly move the trimmer into and out of the area being cut, maintaining the
cutting head position at the desired cutting height. This movement can be either
a forward-backward motion or a side-to-side motion. Cutting shorter lengths
produces best results.
Trim only when grass and weeds are dry.
Wire and picket fences can cause extra string wear or breakage. Stone and brick
walls, curbs, and wood may wear strings rapidly.
Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can
easily be damaged by the strings.

ADJUSTING CUTTING
LINE LENGTH
The trimmer head allows the operator to
release more cutting line without stopping
the motor. As line becomes frayed or worn,
additional line can be released by lightly
tapping the bump knob on the ground
while operating the trimmer (Fig. 13).
WARNING:
Do not remove or alter
the line cutting blade assembly. Excessive line length will cause the motor to overheat
and may result in serious personal injury.
For best results, tap the bump knob on bare ground or hard soil. If line release is
attempted in tall grass, the motor may overheat. Always keep the trimming line fully
extended. Line release becomes more difficult as the cutting line becomes shorter.
LINE REPLACEMENT
NOTICE: Always use the recommended nylon cutting line with a diameter that does not
exceed 0.095 in. (2.4 mm). Using line other than that specified may cause the string
trimmer to overheat or become damaged.
WARNING:
Never use metal-reinforced line, wire, or rope, etc. These can break
off and become dangerous projectiles.
WARNING:
To prevent serious personal injury, remove the battery pack from the
tool before servicing, cleaning, changing attachments or removing material from the
unit.
1. Remove the battery pack.
2. Rotate the spool retainer in the
arrow direction as necessary to
align the LOAD line on the spool
retainer with the eyelets in the spool
base (Fig. 14).

3. Cut one piece of cutting line 16 ft.
(5m) long. Insert the line into the
mounting hole, which is located
inside the eyelet. Push until the end
of the line comes out of the other
side of the spool base. Pull the
line from the other side until equal
amounts of line appear on both
sides of the spool (Fig. 15).
4. Rotate the spool retainer in the
direction of the arrow to wind
the line onto the spool until
approximately 5.5 in. (14cm) of line
is showing on each side (Fig. 16).
5. Push the spool retainer down while
pulling on lines to manually advance
the line and to check for proper
assembly of the trimmer head.
RELOAD THE CUTTING LINE, IF
NECESSARY
NOTICE: When the cutting line breaks from the line outlet or the cutting line is not
released when the trimmer head is tapped, you need to remove the remaining cutting
line from the spool retainer and follow the steps below to reload the line.
1. Remove the battery pack.
