General Safety Rules
Proposition 65 Warning
This product contains a chemical or chemicals
known to the State of California to cause cancer,
birth defects, or reproductive harm.
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.
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.

D. 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
E. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
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.
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.
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.
H. Keep hands and feet away from the cutting area.
I. This device should not be used by persons
(including childre3n) with reduced physical,
sensory or mental abilities, or lack of experience or

knowledge, unless such persons are supervised
or trained to operate the appliance by a person
responsible for their safety. Children should be
supervised to not use the device as a toy.
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.
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
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.
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. 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

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

deflector shield and blade.
Figure 16
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 17, 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 18).
5. Thread the strings into the eyelet. Install the new spool so
that the strings align with the eyelets in the string head.
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.

Note: Remove any old string remaining on the spool.
3. The spool will accept up to 4.5 m (15 feet) of string. Use
only 1.6 mm (.065 inch) diameter monofilament string.
Note: Do not use any other gauge or type of string, as
this could damage the trimmer.
4. Insert the string into the anchor holes 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.
Clean all foreign material from the product.
Keep away from corrosive agents such as garden chemicals
and de-icing salts.
Use the storage mode on the battery charger if it will be
unused for 1 month or longer. Refer to Charging the Battery
Pack (page 9).
Store it in a well-ventilated place that is inaccessible to
5. Place the string in the slot on the upper spool flange, leaving
about 152 mm (6 inches) extended beyond the slot.
6. Repeat steps 4 and 5 for the lower string.
Using the battery when it is hot can reduce the operating time.
The battery will automatically stop working when it is overheated
to prevent damage to it. Remove the battery from the charger and
allow it to cool before placing it back into the trimmer.
Note: Do not overfill. After winding the string, there
should be at least 6 mm (1/4 inch) between the wound
string and the outside edge of the spool.
Using the battery when there is moisture on the leads can cause
the trimmer to malfunction. Allow the battery to dry or wipe it dry
before placing it back into the trimmer.
7. Replace the spool and the spool retainer. Refer to Replacing
the Spool (page 12).
Using the trimmer to cut thick grass in temperatures above 32° C
(90° F) may reduce the run time. Decrease the motor speed to
help increase the operating time; refer to ( Starting the Trimmer
(page 8).
Failing to clear debris from the trimmer head vents and shaft may
result in reduced run time. The trimmer may also stop working
when it is overheated to prevent damage to the trimmer. Clear
debris from the air vents on the motor housing and shaft and allow
the trimmer to cool before attempting to use the trimmer again.
Refer to (page )
If it is difficult to remove the battery from the trimmer or the
charger, apply some dielectric grease to the battery terminals. Do
not use any other type of lubricant as it can cause damage to the
terminals. Refer to Removing the Battery (page 9).
