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 control.
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. 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 shock.
F. 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 uninentional 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 a rotating
part of 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.
F. 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.
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 designed.
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 users.
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.
F. 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.
B. Do not use battery-operated appliance in the rain.
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.
C. Use only the following type and size battery(ies): Toro battery
model 88502.
D. Remove or disconnect the battery before servicing, cleaning,
or removing material from the gardening appliance.
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.
E. Do not dispose of the battery(ies) in a fire. The cell may
explode. Check with local codes for possible special disposal
Keep guards in place and in working order.
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.
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.
Do not open or mutilate the battery(ies). Released electrolyte
is corrosive and may cause damage to the eyes or skin. It may
be toxic if swallowed.

Stopping the Trimmer
NOTICE! The battery pack is not fully charged when it is
purchased. Before using the trimmer for the first time, place the
battery pack in the charger and charge until the LED indicators
turn green. Make sure to read all safety precautions. With regular
use, it will need shorter charging time. If storing for a prolonged
period of time, remove the battery. When ready to use again,
charge the battery pack until the LED indicators turn green.
To stop the trimmer, release the trigger.
Charging the Battery Pack
NOTICE! For best results, your battery tool should be charged in
a location where the temperature is more than 41 degrees F (5
degrees C) but less than 104 degrees F (40 degrees C). To reduce
the risk of serious personal injury, do not store outside or in
vehicles. Charging time will be increased if not charged within
this range.
Turn the battery upside down and line up the battery terminal with
the slot in the charger (Figure 7 and Figure 8).

accumulation of debris.
Check and tighten all fasteners. If any part is damaged or lost,
repair or replace it.
Brush debris away from air intake vents on the back of the shaft to
prevent the motor from overheating.
Replacing the Spool
Use only .065 in. (1.65 mm) diameter monofilament string. Use original
manufacturer’s replacement string for best performance (Toro part
number 88522).

Operating Tips
Keep the trimmer tilted toward the area being cut; this is the best
cutting area.
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.
Remove the battery.
Push in the tabs on the side of the spool retainer (Figure 12).
Note: Remove any old string remaining on the spool.
The spool will accept up to 15 feet of string.Use only .065 in.
(1.65 mm) diameter monofilament string.
Note: Do not use any other gauge or type of string, as this could
damage the trimmer.
Insert the string into the anchor hole in the upper part of the spool
(Figure 13). Wind the string onto the spool in the direction shown
by the arrows on the spool.
Place the string in the slot on the upper spool flange, leaving about
6 in. (152 mm) extended beyond the slot.
Note: Do not overfill. After winding the string, there should be at
least 1/4 in. (6 mm) between the wound string and the outside
edge of the spool.
Replace the spool and the spool retainer. Refer to Spool
Replacement earlier in this manual.

Pull the spool retainer up to remove it and remove the spool.
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 in. (152 mm).
Install the new spool so that the string aligns with the eyelet in the
string head. Thread the string into the eyelet.
Pull the string extending from the string head so the string releases
from the slot in the spool.
Reinstall the spool retainer by depressing tabs into slots and
pushing down until spool retainer clicks into place.
