Important Safety Instructions
Important Safety Instructions
Introduction
This hedge trimmer is designed for regular maintenance and trimming. It is not designed to cut
branches greater than / inch ( mm) in diameter. Other uses may cause injury and are not
allowed.
Safety Signal Definitions
SYMBOL SIGNAL MEANING
WARNING Indicates a potential hazard which could result in serious injury.
CAUTION Indicates a potential hazard which could seriously damage the tool or
cause minor to moderate injury.
IMPORTANT Following this instruction will increase satisfaction with the tool.
General Power Tool Safety Warnings
WARNING: Read and understand 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.
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
flammable 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 (Fig. ). Distractions
can cause you to lose control.
CAUTION: Establish a bystander safety
zone of 10 ft (3 m) prior to operation of
this equipment. Bystander safety zone is
a 10 ft (3 m) circle around the operator that
must remain free from bystanders, children,
and pets.
Electrical safety
•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.
•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.
FIG. 1

6Hedge Trimmer Model HT275
Important Safety Instructions
•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 or
ground fault circuit interrupter (GFCI). Use
of a RCD (GFCI) reduces the risk of electric
shock.
•Remove plug from the mains immediately
if the cable is damaged or cut.
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 influence of
drugs, alcohol or 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 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 finger on
the switch or energizing 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 (Fig. ). 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 collection can reduce dust-
related hazards.
•Prolonged use of power tools has been
reported to cause vascular, muscular, or
neurological disorders (such as vibration
white finger or Raynaud’s syndrome).
To reduce the risk of injury, follow these
instructions:
– Wear gloves and keep hands and body
warm.
– Maintain a firm grip on the hedge
trimmer, but do not use prolonged,
excessive pressure.
– Take frequent breaks.
The vibration in normal use can differ from the
stated values depending on the material being
cut, maintenance of the cutting system, and
other factors.

Hedge Trimmer Model HT275
Important Safety Instructions
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.
•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.
•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.
Battery Tool Use and Care
•Recharge only with Oregon® Series C
chargers specified by the manufacturer
(Oregon® C, C). A charger that is
suitable for one type of battery pack may
create a risk of fire when used with another
battery pack.
•Use power tools only with specifically
designated Oregon® Series B battery
packs (Oregon® BE, B, BE,
BE, B, B). Use of any other
battery packs may create a risk of injury and
fire.
•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.
•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.
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.

STANCE
Stand with both feet on solid ground, with
weight evenly spread between them.
Do not overreach and do not stand on a ladder,
stepstool, or any raised position that is not
fully secured.
Hold the hedge trimmer as close as possible to
the body to maintain control (Fig. ).
STOPPING THE HEDGE TRIMMER
Release the throttle trigger to stop the hedge
trimmer.
STARTING THE HEDGE TRIMMER
Grasp the front and rear handles firmly. Pull
back on trigger lock-out () with thumb (Fig.
). Squeeze the throttle trigger () until the
cutting blades move at the desired speed. The
front handle switch () is a safety feature; the
hedge trimmer will not start unless it is
activated.
CONTROLLING CUTTING BLADE SPEED
The throttle trigger controls the speed at
which the cutting blades oscillate. Squeeze the
throttle trigger more firmly for faster cutting
speed.
Use the lowest pressure required to cut the
material. This helps to maximize the amount of
cutting time per battery charge and reduces the
number of charging operations required.

Cutting Hedges
WHEN TO CUT
The ideal time to trim hedges varies by plant
type, but it is generally a good practice to trim
during periods of slow growth, after blooming is
complete. Consult with a local plant nursery for
tips on trimming specific plants.
Observe all applicable national and municipal
rules and regulations for cutting hedges.
BASIC CUTTING
WARNING: Always be sure of footing
and hold the hedge trimmer firmly with
both hands while the motor is running.
Check the hedge for foreign objects prior to
cutting to avoid damaging the blades. Remove
any objects that may impede cutting.
Assume the proper grip and stance and start
the hedge trimmer. Hold the hedge trimmer
with the cutting blades angled –° toward
the direction of the cut (Fig. ).
IMPORTANT: The cutting blades
occasionally bind and stop moving when
material becomes lodged in the cutting
blades or if cutting blades contact a wire
or chain-link fence. See “Correcting Blade
Bind” to learn how to fix this.
CUTTING SEQUENCE
If the hedge is well-trained, focus on trimming
new growth until the hedge is in the desired
shape.
Once any large branches are removed, use the
hedge trimmer to trim the sides of the hedge to
the desired length. Trim the top of hedge last
after the sides are complete.
CUTTING VERTICALLY
When cutting the sides of the hedge, start at
the bottom of the hedge. Hold the hedge
trimmer with the cutting blades angled –°
toward the direction of the cut. Move down the
line of the hedge, sweeping the hedge trimmer
slowly up and down in a wide arc (Fig. ).

CUTTING HORIZONTALLY
When cutting the top of the hedge, start with
the nearest edge. Hold the hedge trimmer with
the cutting blades angled –° toward the
direction of the cut. Move down the line of the
hedge, sweeping the hedge trimmer slowly left
and right in a wide arc (Fig. ).
If the hedge top is too wide to cut in one sweep
of the hedge trimmer, do not lean over the
hedge to trim the remainder. Instead, make one
pass down one side of the hedge, and then cut
the remainder from the other side of the hedge.
CORRECTING BLADE BIND
CAUTION: Always remove the battery
before clearing cutting blades to avoid
accidental activation of the cutting
blades.
CAUTION: Cutting blades are sharp.
Always wear gloves when clearing
material from the cutting blades.
Sometimes when cutting flexible, “green”
branches, clippings can become lodged
between the moving parts of the cutting blades
and the stationary part. When this happens, the
cutting blades may suddenly cease to move.
This can also happen if the cutting blades
contact material too strong to cut through,
such as a chain-link fence. This condition is
called blade bind.
Follow these guidelines to safely and
effectively clear the material.
•Wear gloves.
•Remove the battery pack from the hedge
trimmer. See “Removing the Battery Pack”.
•Clear the material that is preventing the
cutting blades from moving.

Maintenance and Cleaning
Maintenance and Cleaning
Hedge Trimmer
WARNING: Inspect the hedge trimmer.
Regular inspection is the first step
to proper maintenance. Follow the
guidelines below to maximize safety
and satisfaction. Have any damaged
or excessively worn parts replaced
immediately. Failure to identify and
replace damaged or worn parts can cause
serious personal injury.
WARNING: Remove the battery pack
from the hedge trimmer before inspecting,
cleaning, or performing maintenance. A
battery operated tool with the battery
pack inserted is always on and can start
accidentally.
CAUTION: When cleaning the hedge
trimmer, do not immerse in water or other
liquids.
CLEAN THE HEDGE TRIMMER
•Wipe dust, leaves, and clippings from the
hedge trimmer.
•Clear the air vents to ensure proper airflow
and prevent overheating.
•Wipe the power head with a clean cloth
moistened with mild soap and water.
•Never use harsh cleaners or solvents.
INSPECT THE CUTTING BLADES
Make sure that cutting blades are sharp, have
no nicks or blunt edges, and do not hang up
or catch when running the hedge trimmer.
Periodically file away nicks and burrs on the
blades to ensure they move freely. Sharp and
free-moving cutting blades cut more easily
than dull or sticky ones.
BLADE CARE
When cutting hedges with heavy sap or in
dusty environments, buildup of sap and dirt can
occasionally cause blades to stick. To prevent
this blade stick condition, clean the blades with
a light coating of liquid silicon lubricant only
on the lubrication area of the cutting blades
(Fig. ) and run the blades briefly to evenly
distribute the lubricant.
IMPORTANT: Do not allow lubricant to
drip inside the body of the hedge trimmer.
Never use grease solvents or aerosol
water displacement products. Do not over
lubricate.
INSPECT THE TIP GUARD
If a tip guard is installed, check to make sure
it is not bent or broken. A bent tip guard can
prevent free movement of the cutting blades. If
the tip guard is bent or broken, have it replaced
at an approved service location.
INSTALL THE BLADE COVER
Slip the blade cover over the cutting blades to
keep them clean, and to prevent them snagging
or cutting people or objects.
