General Safety Rules
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.
protected supply. Use of an RCD reduces the risk of
electric shock.
3. Personal safety
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
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invites accidents.
D. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to
the power tool may result in personal injury.
E. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
B. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
C. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
G. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices
can reduce dust-related hazards.
D. 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.
E. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric
If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)

Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts.
H. 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.
Original Instructions (EN)

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. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
H. Use the power tool, accessories and tool bits etc.,
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.
I. Keep guards in place and in working order.
5. Service
Have your power tool serviced by a qualified repair
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 88508 or 88509 and battery charger
88507 or 88510.
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. Do not open or mutilate the battery. Released electrolyte
is flammable and can cause damage if exposed to fire.
H. 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.
I. Ideal charging temperature is between 5° C and 40° C
(32° and 122° F). Charging outside of this temperature
range will increase the charging time.

2. Ideal cutting range
After each use of the trimmer, complete the following:
1. Remove the battery from the trimmer.
2. Wipe the trimmer clean with a damp cloth. Do not hose the
trimmer down or submerge it in water.
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.
Figure 14
3. Wipe or scrape clean the cutting head area any time there is
an accumulation of debris.
Operating Tips
Keep the trimmer tilted toward the area being cut; this is the
best cutting area (Figure 15, item2.).
The string trimmer cuts when passing the unit from left to
right. This will 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.
4. Check and tighten all fasteners. If any part is damaged or
lost, repair or replace it.
5. Brush debris away from the air vents on the motor housing
and shaft to prevent the motor from overheating (Figure 16).

Replacing the Spool
Replacing the String
1. Remove the battery.
Use only .065 inch (1.6 mm) diameter monofilament string. Use
original manufacturer’s replacement string for best performance
(Toro part number 88518 and 88528).
2. Remove the spool. See Replacing the Spool (Figure 17).
1. Remove the battery.
2. Push in the tabs on the side of the spool retainer (Figure 17).

about 6 inches (152 mm) extended beyond the slot.
3. Pull the spool retainer up to remove it and remove the spool.
6. Repeat steps 4 and 5 for the lower string.
4. To install the new spool, make sure the strings are captured
in the retaining slots on the new spool. Make sure the end of
the strings extends approximately 6 inches (152 mm).
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.
5. Thread the strings into the eyelet. Install the new spool so
that the strings align with the eyelets in the string head.
7. Replace the spool and the spool retainer. Refer to Spool
Replacement earlier in this manual.
6. Pull the strings extending from the string head so the strings
release from the slots in the spool.
7. Reinstall the spool retainer by depressing tabs into slots and
pushing down until spool retainer clicks into place.
