General Safety Rules
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
B. Avoid body contact with earthed or grounded
surfaces. There is an increased risk of electric shock if
your body is earthed or grounded.
C. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
D. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
E. If operating a power tool in a damp location is
unavoidable, use a supply protected by a residual
current device (RCD) in AUS or a ground fault
interrupt (GFI) in the USA. Use of an RCD or GFI
reduces the risk of electric shock.
3. Personal safety
WARNING: When using electric gardening appliances, basic
safety precautions should always be followed to reduce the risk of
fire, electric shock, and personal injury, including the following:
Read all instructions.
The term “power tool” in all of the warnings refers to your
mains-operated (corded) power tool or battery-operated (cordless)
power tool.
1. Work area safety
A. Keep work area clean and well lit. Cluttered or dark
areas invite accidents
B. Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
C. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose
2. Electrical safety
A. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk
of electric shock.

A. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result
in serious personal injury.
B. Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
C. Prevent unintentional starting. Ensure the switch

from moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts.
G. Keep hands and feet away from the cutting area.
4. Power tool use and care
A. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
B. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
C. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
D. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained
E. Store idle appliances indoors. When not in use,
appliances should be stored indoors in a dry and high
or locked-up place, out of the reach of children.
Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power tools
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
G. Use the power tool in accordance with these
instructions and in the manner intended for the
particular type of power tool, taking into account the
working conditions and the work to be performed.
Use of the power tool for operations different from those
intended could result in a hazardous situation.
H. Keep guards in place and in working order.
5. Service

person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
6. Battery Safety
A. Do not charge appliance in rain, or in wet locations.
B. Do not use battery-operated appliance in the rain.
C. Use only the following type and size battery: Toro
battery model 88504 or 88506 and battery charger
D. Remove or disconnect the battery before servicing,
cleaning, or removing material from the gardening
E. Do not dispose of the battery in a fire. The cell 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.
G. 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.

Advancing the Line
The trimmer is equipped with an auto-feed head. The line will
advance 6 mm (1/4 inch) each time you stop and start the
trimmer. When the line reaches the blade in the deflector, it will
be cut off at that length.
1. With the trimmer running, release the switch trigger.
2. Wait two seconds, then press the switch trigger.
3. Resume trimming.
Advancing the Line Manually
Disconnect the string trimmer from the power supply, then push
the red button at the base of the spool retainer while pulling on the

Operating Tips
To use the trimmer as edger, press the rotator button and rotate
the head as shown in Figure 16.
Keep the trimmer tilted toward the area being cut; this is the
best cutting area.
Tilt the trimmer so that the trimmer string is lowest on the
right side.
The string trimmer cuts best when passing the unit from left to
right. This will also avoid throwing debris at the operator.
Use the tip of the string to do the cutting; do not force string
head into uncut grass.
Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may wear
string rapidly.
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the strings.

Using the Power Saver Feature
Engaging the power saver feature will extend the run time of the
battery by shortening the length of the trimmer line and decreasing
the load on the motor.
If you are experiencing reduced battery runtime, it is recommended
that you engage the power saver feature.

3. Pull the spool retainer up to remove it and remove the spool.
4. To install the new spool, make sure the string is captured in
one of the retaining slots on the new spool. Make sure the
end of the string extends approximately 6 inches (152 mm).
After each use of the trimmer, complete the following:
1. Remove the battery from the trimmer.
5. Install the new spool so that the string aligns with the eyelet
in the string head. Thread the string into the eyelet.
2. Wipe the trimmer clean with a damp cloth. Do not hose the
trimmer down or submerge it in water.
6. Pull the string extending from the string head so the string
releases from the slot in the spool.
7. Reinstall the spool retainer by depressing tabs into slots and
pushing down until spool retainer clicks into place.
The line cut-off blade on the deflector is sharp and
can cut you. Do not use your hands to clean the
deflector shield and blade.
Replacing the String
1. Remove the battery.
2. Remove the spool. See Replacing the Spool (Figure 19).
3. Wipe or scrape clean the cutting head area any time there is
an accumulation of debris.
4. Check and tighten all fasteners. If any part is damaged or
lost, repair or replace it.
5. Brush debris away from air intake vents on motor housing
to prevent the motor from overheating.
Replacing the Spool
Use only .065 inch (1.6 mm) diameter monofilament string. Use
original manufacturer’s replacement string for best performance
(Toro part number 88532 or 88524).
Important: Use of a larger diameter string will cause the
motor to overheat and fail.
1. Remove the battery.
2. Push in the tabs on the side of the spool retainer (Figure 19).

Note: Remove any old string remaining on the spool.
3. The spool will accept up to 15 feet (4.5 m) of string. Use
only .065 inch (1.6 mm) diameter monofilament string.
Note: Do not use any other gauge or type of string, as this
could damage the trimmer.
Before recycling, cover the battery pack's terminals
with heavy-duty adhesive tape. Do not attempt to
destroy or disassemble the battery pack or remove
any of its components. Lithium-ion batteries must be
recycled or disposed of properly at the nearest battery
recycling facility.
4. Insert the string into the anchor hole in the upper part of
the spool (Figure 20). Wind the string onto the spool in the
direction shown by the arrows on the spool.
5. Place the string in the slot on the upper spool flange, leaving
about 6 inches (152 mm) extended beyond the slot.
Note: Do not overfill. After winding the string, there should
be at least 1/4 inch (6 mm) between the wound string and
the outside edge of the spool.
6. Replace the spool and the spool retainer. Refer to
Replacing the Spool (page 12).
