Guide to Using this Manual Safety Precautions and

Working Techniques

Because a hedge trim-

mer is a high-speed, fast-

cutting power tool with

sharp cutting blades and

is powered by electricity,

special safety precau-

tions must be observed to

reduce the risk of per-

sonal injury.

It is important that you

read, fully understand

and observe the following

safety precautions and

warnings. Read the

instruction manual and

the safety precautions

periodically. Careless or

improper use may cause

serious or fatal injury.

HSA 66

English

Use your hedge trimmer only for cutting

hedges, shrubs, scrub and similar

material.

WARNING

Do not use it for other purposes, since

misuse may result in personal injury or

property damage, including damage to

the machine.

WARNING

Minors should never be allowed to use

this power tool. Bystanders, especially

children, and animals should not be

allowed in the area where it is in use.

WARNING

To reduce the risk of injury to bystanders

and damage to property, never let your

power tool run unattended. When it is

not in use (e.g. during a work break),

shut it off and make sure that

unauthorized persons do not use it. To

do this, move retaining latch to ƒ and

remove the battery from the power tool.

Most of these safety precautions and

warnings apply to the use of all STIHL

hedge trimmers. Different models may

have different parts and controls. See

the appropriate section of your

instruction manual for a description of

the controls and the function of the parts

of your model.

Always remove the battery and move

retaining latch to ƒ before transporting,

storing or carrying out any work on the

power tool. This avoids the risk of the

motor starting unintentionally.

STIHL recommends the use of original

STIHL replacement parts. They are

specifically designed to match your

model and meet your performance

requirements.

Safe use of a hedge trimmer involves

1. the operator

2. the power tool

3. the use of the power tool.

THE POWER TOOL

For illustrations and definitions of the

power tool parts see the chapter on

"Main Parts."

WARNING

Never modify this power tool in any way,

since this may increase the risk of

personal injury. Only attachments

supplied by STIHL or expressly

approved by STIHL for use with the

specific STIHL model are authorized.

Although certain unauthorized

attachments are useable with STIHL

power tools, their use may, in fact, be

extremely dangerous.

If your power tool is subjected to

unusually high loads for which it was not

designed (e.g. heavy impact or a fall),

always check that it is in good condition

before continuing work – see also

"Before Starting Work." Make sure the

safety devices are working properly. Do

not continue operating your power tool if

it is damaged. In case of doubt, have the

machine checked by your STIHL

servicing dealer.

Battery

WARNING

Do not place the battery on or near fires,

stoves or in other high-temperature

locations. Do not place the battery in

direct sunlight or store it inside a vehicle

in hot weather. Doing so may cause the

battery to generate heat, rupture or

ignite. Using the batteries in this manner

may also result in a loss of performance

and a shortened battery life.

In case of fire: stay clear of any vapors

or gases generated, taking wind

direction into account. If possible without

danger, remove battery from the vicinity

of the fire. In principle, cooling the

battery or extinguishing the fire with

water is possible. It is preferable to

extinguish the fire with a multipurpose

dry chemical fire extinguisher. As for any

fire, evacuate the area and fight the fire

from a safe distance. Once the fire has

been extinguished, the area should be

monitored (fire watch) in case of a flare-

up, until the battery has cooled

sufficiently. Restrict access to the area

until completion of clean-up. Do not

touch the burnt battery or any spilled

liquids. Use inert absorbent to absorb

spilled liquids.

WARNING

Use STIHL batteries only with STIHL

power tools, and charge them only with

STIHL chargers. Replace battery with

STIHL battery only. Use only genuine

STIHL rechargeable batteries.

Charge the battery before use.

WARNING

Do not open, drop, hit or damage

battery. Never insert objects into the

battery's cooling slots, since they may

damage the battery. The battery

contains safety features and devices

which, if damaged, may cause the

battery to generate heat, rupture or

ignite. Never use or charge a defective,

damaged, cracked or deformed battery.

Immediately discontinue use of the

battery if, while using, charging or

storing, it emits an unusual smell, feels

hot or appears abnormal in any other

way.

Always wear heavy duty

work gloves (e.g. made of

leather or other wear

resistant material) when

handling the machine

and the cutting tool.

Heavy-duty, nonslip

gloves improve your grip

and help to protect your

hands.

Risk of fire, explosion

and/or burns, including

chemical burns. Do not

disassemble, crush, heat

above 212 °F (100 °C),

expose to fire or inciner-

ate. Never expose the

battery to microwaves or

high pressures.

Use and store the bat-

tery only within a

temperature range from

14 °F (-10 °C) up to no

more than 122 °F

(+ 50 °C). Protect the bat-

tery from direct sunlight.

Do not immerse the bat-

tery in fluids.

HSA 66

English

WARNING

Fluid may leak from the battery if it is

damaged or is not used properly – avoid

contact with the skin! Leaking battery

fluid can cause skin irritation and

chemical burns. In the event of

accidental contact, immediately rinse

thoroughly with mild soap and water. If

fluid gets into your eye(s), do not rub

your eye(s) but rinse water over the

open eye(s) for 15 minutes at least. Also

seek medical attention immediately.

WARNING

Never bridge (short circuit) the battery

terminals with metallic objects, since this

may damage the battery and possibly

cause a fire. Keep a battery that is not in

use away from metal objects (e.g. nails,

coins, jewelry). Do not use metal

containers for transporting batteries.

Store the battery out of reach of children

in a cool and dry area away from direct

sunlight and excess heat or cold (14 °F

– 122 °F (-10 °C – +50 °C)).

Charger

Use only original STIHL chargers.

Use only for charging geometrically

matching STIHL batteries with a

maximum capacity of 50 Ah and a

maximum voltage of 42 V.

Never charge defective, leaking or

deformed batteries.

Connect the charger only to a power

supply with the voltage and frequency

specified on the rating plate. Always

plug the charger into a properly installed

wall outlet. Do not use an extension cord

unless absolutely neccessary (see

below).

Never use a charger with damaged

housing, damaged power supply cord or

damaged plug. Do not operate the

charger if it has received a sharp blow,

been dropped or otherwise damaged in

any way.

Do not open or dissassemble charger –

there are no user serviceable parts

inside.

Store charger out of the reach of

children.

Operate charger at temperatures

between 41 °F (5 °C) and 104 °F

(40 °C).

Allow the charger to cool down normally

– do not cover it.

Never bridge the contacts of the charger

with metallic objects (e.g. nails, coins,

jewelry) – short circuit. The charger will

be damaged by a short circuit.

In the event of smoke or fire in the

charger, disconnect it from outlet

immediately.

WARNING

To reduce the risk of electric shock or

short circuit, do not insert any objects

into the charger's cooling slots.

WARNING

The charger heats up during the

charging process. Do not operate on an

easily combustible surface (e.g. paper,

cardboard, textiles) or in an easily

combustible environment – risk of fire.

WARNING

Do not operate in a hazardous location,

i.e. in a location where there are

combustible liquids (fumes), vapors or

dusts. Chargers can produce sparks,

which may ignite the dust or vapors –

risk of explosion.

Never jerk the power supply cord to

disconnect it from the wall outlet. To

unplug, grasp the plug, not the cord.

Have a damaged power supply cord

repaired by an experienced electrician.

Do not use the power supply cord for

any other purpose, e.g. for carrying or

hanging up the charger.

Never use power supply cords that do

not comply with regulations.

Protect the charger from

rain and dampness. Keep

charger dry.

Use and store charger

only indoors in dry rooms. Check the charger's

power supply cord and

plug regularly for dam-

age. If the power supply

cord or plug is damaged,

immediately disconnect

the plug from the wall

outlet to avoid the risk of

electric shock.

HSA 66

English

Make sure the power supply cord is

located and/or marked so that it will not

be stepped on, tripped over, come in

contact with sharp edges or moving

parts or otherwise be subjected to

damage or stress.

An extension cord should not be used

unless absolutely necessary. If an

extension cord must be used, plug the

charger into a properly wired 16 gauge

(AWG 16) or heavier gauge extension

cord with blades that are the same

number, size and shapes as the blades

on the charger.

To reduce the risk of electric shock:

–Always connect the unit to a

properly installed wall outlet.

–Make sure the insulation of the

power supply cord and plug is in

good condition.

Unplug the power supply cord from the

outlet when charger is not in use.

tightened and in safe operating

condition. Inspect for loose parts (nuts,

screws, etc.) and for cracked, bent,

warped or damaged blades. Regularly

check the condition and tightness of the

cutting blades – with the motor stopped,

retaining latch on ƒ and battery

removed! Replace damaged cutting

blades before using the power tool.

Always keep blades sharp.

STIHL recommends that you always

spray the cutting blades with STIHL

resin solvent before starting work – with

the motor stopped, retaining latch on ƒ

and battery removed! You can obtain

this protective spray from your dealer.

Apply generously.

Check contacts in battery compartment

for foreign matter. Keep clean.

Fit the battery correctly – it must engage

audibly.

For specific starting instructions, see the

appropriate section of your instruction

manual.

WARNING

To reduce the risk of injury from blade

contact, be absolutely sure that the

cutting blades are clear of you and all

other obstructions and objects, including

the ground.

WARNING

Your power tool is a one-person

machine. Do not allow other persons in

the general work area, even when

starting.

During Operation

Holding and Controlling the Power Tool

Always hold the unit firmly with both

hands on the handles while you are

working. Wrap your fingers and thumbs

around the handles.

Right-Handers

Right hand on the control handle and left

hand on the loop handle.

Left-Handers

Left hand on the control handle and right

hand on the loop handle.

Make sure you have firm and secure

footing and hold the unit so that the

cutting blades are always away from

your body.

WARNING

Do not overreach. Keep proper footing

and balance at all times. Special care

must be taken in slippery conditions (wet

ground, snow) and in difficult, overgrown

terrain. Watch for hidden obstacles such

as tree stumps, roots and ditches to

avoid stumbling. For better footing, clear

away fallen branches, scrub and

cuttings. Be extremely cautious when

working on slopes or uneven ground.

Working Conditions

Operate your power tool only under

good visibility and daylight conditions

only. Work carefully.

9938BA007 KN

9938BA006 KN

Never attempt to operate

your power tool with one

hand. Loss of control of

the power tool resulting in

serious or fatal injury may

result. To reduce the risk

of cut injuries, keep

hands and feet away

from the cutting blades.

Never touch moving cut-

ting blades with your

HSA 66

English

Do not cut any material other than

hedges or similar soft vegetation. Do not

cut stems greater than 17 mm (0.7 inch)

thick.

WARNING

If the vegetation being cut or the

surrounding ground is coated with a

chemical substance (such as an active

pesticide or herbicide), read and follow

the instructions and warnings that

accompanied the substance at issue.

WARNING

Inhalation of certain dusts, especially

organic dusts such as mold or pollen,

can cause susceptible persons to have

an allergic or asthmatic reaction.

Substantial or repeated inhalation of

dust and other airborne contaminants, in

particular those with a smaller particle

size, may cause respiratory or other

illnesses. Control dust at the source

where possible. Use good work

practices, such as operating the unit so

that the wind or operating process

directs any dust raised by the power tool

away from the operator. Follow the

recommendations of EPA / OSHA /

NIOSH and occupational and trade

associations with respect to dust

("particulate matter.") When the

inhalation of dust cannot be

substantially controlled, i.e., kept at or

near the ambient (background) level, the

operator and any bystanders should

wear a respirator approved by NIOSH /

MSHA for the type of dust encountered.

If the hedge is very dusty or dirty, spray

the blades with STIHL resin solvent from

time to time during cutting. This helps

reduce blade friction as well as the

aggressive effects of sap and the build-

up of dirt particles.

Operating Instructions

WARNING

In the event of an emergency, switch off

the motor immediately, move retaining

latch to ƒ and remove the battery.

WARNING

Before you start work, examine the

hedge area for stones, fence wire, metal

or other solid objects which could

damage the cutting blades.

Take particular care when cutting

hedges next to or against wire fences.

Do not touch the wire with the cutting

blades. When working close to the

ground, make sure that no sand, grit or

stones get between the cutting blades.

Striking solid foreign objects such as

stones, fence wire or metal could

damage the cutting attachment and may

cause blades to crack, chip or break.

STIHL does not recommend the use of

your power tool when cutting in areas

where the blades could contact such

objects.

WARNING

Observe the cutting blades at all times –

do not cut any areas of the hedge that

you cannot see. When cutting the top of

a taller hedge, check the other side of

the hedge frequently for bystanders,

animals and obstructions. Do not

insulation against elec-

tric shock. To reduce the

risk of electrocution,

never operate this power

tool in the vicinity of any

wires or cables (power,

etc.) which may be carry-

ing electric current.

HSA 66

English

WARNING

To reduce the risk of injury from loss of

control, never work on a ladder, in a tree

or any other insecure support. Never

hold the machine above shoulder

height.

Be particularly alert and cautious when

HSA 66

English

This chapter relays the prescribed

wording of general safety advice for

handheld motor-operated electric hedge

trimmers contained in UL 60745-1 and

UL 60745-2-15.

The safety precautions and warnings on

avoiding an electric shock given under

"2) Electrical safety" do not apply to

STIHL cordless electric power tools.

WARNING

Read all safety warnings and all

instructions. Failure to follow the

warnings and instructions may result in

electric shock, fire 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.

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 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 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.

General Power Tool Safety

Warnings

HSA 66

English

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 dust collection can reduce

dust-related hazards.

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 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) Maintain power tools. 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.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools

with sharp cutting edges are less

likely to bind and are easier to

control.

g) 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.

5) Battery tool use and care

a) Recharge only with the charger

specified by the manufacturer. A

charger that is suitable for one type

of battery pack may create a risk of

fire when used with another battery

pack.

b) Use power tools only with

specifically designated battery

packs. Use of any other battery

packs may create a risk of injury and

fire.

c) 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 fire.

d) Under abusive conditions, liquid

may be ejected from the battery;

avoid contact. If contact accidentally

occurs, flush with water. If liquid

contacts eyes, additionally seek

medical help. Liquid ejected from

the battery may cause irritation or

burns.

6) Service

a) 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.

Hedge Trimmer Safety Warnings

–Keep all parts of the body away

from the cutter blade. Do not

remove cut material or hold material

to be cut when blades are moving.

Make sure the switch is off when

HSA 66

English

clearing jammed material. Blades

coast after turn off. A moment of

inattention while operating the

hedge trimmer may result in serious

personal injury.

–Carry the hedge trimmer by the

handle with the cutter blade

stopped. Proper handling of the

hedge trimmer will reduce possible

personal injury from the cutter

blades.

–Hold the power tool by insulated

gripping surfaces only, because the

cutter blade may contact hidden

wiring. Cutter blades contacting a

"live" wire may make exposed metal

parts of the power tool "live" and

could give the operator an electric

shock.

DANGER

–Keep hands away from blade.

Contact with blade will result in

serious personal injury.

Cutting Season

Observe country-specific or municipal

rules and regulations for cutting hedges.

NDo not use your power tool during

other people's rest periods.

Cutting Sequence

NUse lopping shears or a chain saw

to cut out thick branches first.

NCut both sides of the hedge first,

then the top.

Recommendation: Only cut hedges that

are no more than chest height.

Disposal

NDo not throw cuttings into the

garbage can – they can be

composted!

Working Techniques

Vertical cut

Swing the cutting blade from the bottom

upwards in an arc – lower the nose of the

blade, move along the hedge and then

swing the blade up again in an arc.

Any working position above head height

is tiring. To minimize the risk of

accidents, work in such positions for

short periods only.

English

Horizontal cut

Hold the cutting blade at an angle of 0°

to 10° as you swing the hedge trimmer

horizontally, using both sides of the

blade.

Swing the cutting blade in an arc

towards the outside of the hedge so that

the cuttings are swept to the ground.

Repeat the procedure several times on

wide hedges.

Power supply (mains) voltage and

operating voltage must be the same.

NInsert the plug (1) in the wall

outlet (2).

A self test is performed after the charger

is connected to the power supply. During

this process, the light emitting diode (1)

on the charger lights up green for about

1 second, then red and goes off again.

When delivered, the battery is not fully

charged.

It is advisable to charge the battery

completely before using it for the first

time.

NConnect the charger to the power

supply – mains voltage and

operating voltage of the charger

must be the same – see

"Connecting Charger to Power

Supply".

Operate the charger only in a closed, dry

space at ambient temperatures between

41 °F (5 ° C) and 104 °F (40 °C).

Only charge dry batteries. Allow a damp

battery to dry before charging.

NSlide the battery (1) into the

charger (2) until you start to feel

resistance – then push it in until it

engages.

see "LEDs on Battery".

Charge time depends on a number of

factors, including battery condition,

ambient temperature, etc., and may

therefore vary from the times specified.

The battery heats up during operation in

the power tool. If a hot battery is inserted

in the charger, it may be necessary to

cool it down before charging. The

charging process begins only after the

battery has cooled down. The time

required for cooling may prolong the

charge time.

The battery and charger heat up during

the charging process.
