OREGON® Cordless Tool System  
TRIMMER/EDGER MODEL ST275  
SAFETY RULES  
INTRODUCTION  
This trimmer/edger is designed for regular maintenance trimming of grass and  
weeds using flexible nylon trimmer line. It is not designed to clear heavy brush  
or for use with any metal cutting attachments. Any other use other than stated is  
not recommended. This product has been designed in accordance with the state  
of the art safety technology of the time. However, even with this technology, it is  
recognised that residual risk, such as thrown objects, still exist. The operator is  
directed to closely read, understand, and follow all safety precautions to reduce  
potential injury from these risks.  
SAFETY RULES  
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 TOOLIN THE WARNINGS REFERS TO YOUR MAINS-OPERATED  
(CORDED) POWER TOOL OR BATTERY OPERATED (CORDLESS) POWER TOOL.  
WORK AREA SAFETY  
ELECTRICAL SAFETY  
Keep work area clean and well lit.  
Cluttered or dark areas invite accidents.  
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.  
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.  
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.  
Keep children and bystanders away  
while operating a power tool.  
Distractions can cause you to lose control.  
CAUTION: ESTABLISH A  
Do not expose power tools to rain or  
wet conditions. Water entering a power  
tool will increase the risk of electric shock.  
BYSTANDER SAFETY ZONE OF 6 M  
(20 FT) PRIOR TO OPERATION OF  
THIS EQUIPMENT. Bystander safety zone  
is a 6 m (20 ft) circle around the operator  
that must remain free from bystanders,  
children, and pets.  
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.  
AB 0214 - F/N 564571

OREGON® Cordless Tool System  
TRIMMER/EDGER MODEL ST275  
SAFETY RULES  
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.  
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 jewellery. Keep your hair,  
clothing and gloves away from moving  
parts. Loose clothes, jewellery or long hair  
can be caught in moving parts.  
Hold the power tool by insulated  
gripping surfaces only, because the  
trimmer may contact hidden wiring.  
Power tools contacting a “live” wire may make  
exposed metal parts of the power tool “live”  
and could give the operator an electric shock.  
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.  
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.  
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 trimmer/  
edger, but do not use prolonged,  
excessive pressure.  
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.  
Take frequent breaks.  
The vibration in normal use can  
differ from the values stated in the  
“Specifications and Componentstable  
depending on the material being cut,  
maintenance of the cutting system, and  
other factors  
Use personal protective equipment.  
Always wear long pants and foot  
protection.  
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 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.

TRIMMER/EDGER MODEL ST275  
SAFETY RULES  
POWER TOOL USE AND CARE  
BATTERY 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.  
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.  
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.  
Use power tools only with specifically  
designated battery packs.  
Use of any other battery packs may create a  
risk of injury and fire.  
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.  
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.  
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.  
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.  
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.  
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  
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.

CAUTION: TO REDUCE THE RISK  
OF INJURY, ALWAYS WEAR PROPER  
EYE AND EAR PROTECTION, LONG  
PANTS, AND FOOT PROTECTION.  
STARTING THE TRIMMER/EDGER  
Grasp the front and rear handles firmly  
Squeeze the trigger lock-out (1), then  
squeeze the throttle trigger (2) until the  
trimmer head moves at the desired  
speed (Fig  14)  
IMPORTANT: USE CARE AROUND  
STRUCTURES, TREES, AND BUSHES TO  
AVOID DAMAGING PAINT OR BARK.  
FIG. 14  
OPERATING TEMPERATURE  
(1) TRIGGER LOCK-OUT  
This trimmer/edger is designed to  
operate within a temperature range of  
0°C to 40°C (32°F to 104°F)  
(2) THROTTLE TRIGGER  
GRIP  
The front handle on the trimmer/edger  
handle is adjustable  You can move the  
handle forward or backward along the  
shaft until it is in a comfortable position  
for trimming, clearing, or edging  
Loosen the adjustment knob until the  
front handle slides along the shaft, move

OPERATING THE TRIMMER/EDGER  
CONTROLLING TRIMMER HEAD  
SPEED  
TRIMMING  
The throttle trigger controls the speed at  
which the trimmer head turns  Squeeze  
the throttle trigger more firmly for faster  
cutting speed  
Trimming cuts grass and weeds that are  
close to walls, fences, and other areas too  
small to reach with a lawn mower, down  
to a manageable height but not down to  
soil level  
Use the lowest pressure required to cut  
the material  This helps to maximise  
the amount of cutting time per battery  
charge and reduces the number of  
charging operations required  
Assume proper grip and stance, then  
start the trimmer  Squeeze the throttle  
trigger until the trimmer head achieves  
the minimum speed necessary to cut the  
grass or weeds  
ADVANCING TRIMMER LINE  
The trimmer line wears down as you use  
the trimmer/edger  Let out more trimmer  
line as needed  
With the motor running and the trimmer  
head turning, bump the trimmer head on  
the ground (Fig  15)  More trimmer line  
comes out of the spool, and excess  
trimmer line is cut off by the line cutting  
blade on the bottom of the guard  
Angle the trimmer head slightly toward  
the direction of the cut (Fig  16)  
FIG. 16  
FIG. 15  
5–10°  
If the trimmer line does not come out,  
the spool may be empty  Turn off the  
trimmer/edger and replace trimmer line  
as described inReplacing trimmer line  
Push the trimmer head slowly from the  
side into the grass or weeds to be cut,  
and move the trimmer head back and  
forth so that the end of the trimmer line  
contacts the material to be cut  
Do not allow the trimmer line to touch  
the ground

TRIMMER/EDGER MODEL ST275  
OPERATING THE TRIMMER/EDGER  
In tight spaces, such as against a fence or  
other barrier, it is acceptable to reverse  
grip on the rear handle and hold the  
trimmer/edger in a more vertical position  
(Fig  18)  
EDGING  
FIG. 18  
CAUTION: TO REDUCE THE RISK  
OF INJURY, KEEP THE GUARD  
BETWEEN THE OPERATOR AND THE  
TRIMMER HEAD.  
Edging maintains an existing border  
between a lawn and another object such  
as a sidewalk, pavement, or flower bed  
The trimmer/edger is not designed for  
creating a new hard edge, but is useful  
for keeping an existing edge clean  
Keep hands away from the throttle  
trigger, then move the edging guard so  
that it extends from the trimmer and  
clicks into place  
Approach the lawn with the trimmer  
turned so that the bottom of the  
trimmer head is pointed toward the side  
of the lawn and the edging guide is  
pointed toward the ground  Position the  
edge guide along the edge of the lawn  
(Fig  17)  
For extended periods of edging, it is  
acceptable to rotate the front handle  
(Fig  19)  This may provide a more  
comfortable grip

WARNING: THERE ARE NO  
USER SERVICEABLE PARTS INSIDE  
THE BATTERY PACK. DO NOT  
DISASSEMBLE.  
Lithium ion batteries have a finite  
operating life  If the amount of cutting  
time per charge decreases noticeably, the  
battery pack is at the end of its useful life  
and should be replaced  
Certain types and lengths of grass can  
sometimes be caught between the  
trimmer head and the spindle  When this  
happens, the grass quickly winds around  
the shaft clogging the space between the  
shaft and the trimmer head and slowing  
or stopping the trimmer head rotation  
This condition is called grass bind  The  
trimmer/edger is equipped with a grass  
wrap protector shroud between the  
trimmer head and the spindle to help  
minimize grass bind, but the condition  
can still occasionally occur  
• Make sure the battery pack, including  
the contacts, is clean, dry, and has no  
signs of puncture, impact, or other  
damage  Broken batteries can cause  
fires or emit hazardous chemicals  
• Clean dirty contacts with a soft, dry  
cloth  Dirt or oil can cause a poor  
electrical connection resulting in loss of  
power  
CHARGER  
• Unplug the charger from the electrical  
outlet  
To correct grass bind:  
• Remove the battery  
• Remove the trimmer head  
• Clean dirty contacts with a soft, dry  
cloth  
• Clean all grass or weeds from the  
spindle  If necessary, cut the grass or  
weeds free
