GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and specications
provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, re
and/or serious injury.
Save all warnings and instructions for future
reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.

56 VOLT LITHIUM-ION CORDLESS LINE TRIMMER — ST1520E-S 7
EN
WORK AREA SAFETY
◾Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
◾Do not operate power tools in explosive
atmospheres, such as in the presence of
ammable liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
◾Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
ELECTRICAL SAFETY
◾Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adaptor
plugs with earthed (grounded) power tools.
Unmodied plugs and matching outlets will reduce risk
of electric shock
◾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.
◾Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
◾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.
◾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.
◾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.
PERSONAL SAFETY
◾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 inuence of drugs, alcohol medication. A
moment of inattention while operating power tools
may result in serious personal injury.
◾Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
◾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 nger on the
switch or energising power tools that have the switch
on invites accidents.
◾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.
◾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.
◾If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
devices can reduce dust-related hazards.
◾Recommendation that the tool always be supplied
via a residual current device having a rated
residual current of 30 mA or less.
◾Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
◾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.
◾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.
◾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.
◾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.

56 VOLT LITHIUM-ION CORDLESS LINE TRIMMER — ST1520E-S8
EN
◾Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may affect
the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
◾Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
◾Use the power tool, accessories and tool bits etc.
in accordance with these instructions, 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.
◾Keep handles and grasping surface dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
◾Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used
with another battery pack.
◾Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
◾When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause
burns or a re.
◾Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
◾Do not use a battery pack or tool that is damaged
or modied. Damaged or modied batteries may
exhibit unpredictable behaviour resulting in re,
explosion or risk of injury.
◾Do not expose a battery pack or tool to re
or excessive temperature. Exposure to re or
temperature above 100 °C may cause explosion.

locations.
Clear the area to be cut before each use. Remove all
objects, such as rocks, broken glass, nails, wire, or line,
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 15m 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 and cutting attachment immediately.
Before each use, check for damage/worn parts
Check the bump head, guard and front-assist handle
and replace the 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 le or replace it with a new blade.
WARNING: Always wear gloves when mounting the
guard or servicing the blade. Take care of the blade on

56 VOLT LITHIUM-ION CORDLESS LINE TRIMMER — ST1520E-S12
EN
◾Use only mild soap and a damp cloth to clean the tool.
Never let any liquid get inside the tool; never immerse
any part of the tool into a liquid.
◾Keep air vents in the motor housing from debris at all
times.
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 cloths
to remove dirt, dust, oil, grease, etc.
TIPS FOR BEST TRIMMING RESULTS (Fig. M)
◾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 efciency and
may overload the motor.
◾The cutting height is determined by the distance of the
cutting line from the lawn surface.
◾Grass over 20cm should be cut by working
progressively 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 line wear or
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
◾Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
line.
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 spool retainer on the ground while operating
the trimmer (Fig. N).
NOTICE: Line release will become more difcult as the
cutting line becomes shorter.
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.
LINE REPLACEMENT
NOTICE: Always use the recommended nylon cutting
line with a diameter that does not exceed 2.4 mm. Using
line other than that specied may cause the line trimmer
to overheat or become damaged.
WARNING: Never use metal-reinforced line, wire,
or rope, etc. These can break off and become dangerous
projectiles.
The line trimmer is equipped with an advanced
POWERLOADTM system. The cutting line can be wound
onto the spool simply by pressing a single button. Loading
a full spool can usually be completed in 12 seconds.
Avoid repeated operation of the winding system in rapid
succession to reduce the possibility of motor damage.
1. Remove the battery pack.
2. Remove the remaining cutting line, if necessary.
Simply pull it out by hand.
3. Cut one piece of cutting line (4m) long. Insert the line
into the eyelet (Fig. O) and push the line until the end
of the line comes out of the opposite eyelet.
4. Remove the battery if it has been mounted onto the
line trimmer in previous step.
NOTICE: If the line cannot be inserted into the eyelet,
mount the battery pack onto the trimmer, then press the
line-loading button briey to release the lower cover.
5. Pull the line from the other side until equal lengths
of the line appear on both sides of the trimmer head
(Fig. P).
6. Install the battery pack onto the line trimmer.
Press and hold the line-loading button to start the
line-winding motor. The line will be wound into the
trimmer head continuously (Fig. Q).
7. Watch the remaining line length carefully. Prepare to
release the button as soon as approximately 18cm of
line are left on each side. Briey press the
line-loading button to adjust the length until 14cm of
the line is showing on each side.
8. Push down on the trimmer head while pulling on the
lines to manually advance the line in order to check
for proper assembly of the cutting line.
NOTICE: In case the line is pulled into the trimmer head
by accident, open the head and pull the cutting line
out from the spool. Follow the section “RELOAD THE
CUTTING LINE” in this manual to reload the line.
