Pole Saw Model PS250
Important Safety Instructions
Important Safety Instructions
Introduction
The pole saw is designed for regular maintenance and cutting of branches  in ( cm) or less
in diameter. Other uses may cause injury and are not recommended. However, even with this
technology, it is recognized 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 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  ft ( m) prior to operation of
this equipment. Bystander safety zone is
a  ft ( m) circle around the operator that
must remain free from bystanders, children,
and pets.
30 ft (9 m)

Important Safety Instructions
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.
•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.
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.
FIG. 2

Pole Saw Model PS250
Important Safety Instructions
•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.
Extended Reach Pole Saw Safety
•Keep all parts of the body away from the
saw chain. Do not remove cut material
or hold material to be cut when blades
are moving. Make sure the switch is off
when clearing jammed material. Saw chain
continues to move after the switch is turned
off. A moment of inattention while operating
the extended-reach pole saw may result in
serious personal injury.
•Carry the extended-reach pole saw by the
handle with the saw chain stopped. When
transporting or storing the extended-
reach pole saw, always fit the saw
chain device cover. Proper handling of the
extended-reach pole saw will reduce possible
personal injury from the saw chain.
•Hold the extended-reach pole saw by
insulated gripping surfaces only, because
the saw chain may contact hidden wiring.
A saw chain contacting a “live” wire may make
exposed metal parts of the extended-reach
pole saw “live” and could give the operator an
electric shock.
•Do not use the extended-reach pole saw
in bad weather conditions, especially
when there is a risk of lightning. This
decreases the risk of being struck by lightning.
•To reduce the risk of electrocution, never
use near any electrical power lines.
Contact with or use near power lines may
cause serious injury or electric shock resulting
in death.
•Always use two hands when operating
the extended-reach pole saw. Hold the
extended-reach pole saw with both hands to
avoid loss of control.
•Always use head protection when
operating the extended-reach pole saw
overhead. Falling debris can result in serious
personal injury.
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.

8Pole Saw Model PS250
Important Safety Instructions
•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 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.
•Use power tools only with specifically
designated battery packs. 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.
Pole Saw Safety Warnings

Unpacking
What’s in the box?
The pole saw requires some assembly before
use. These items ship with the pole saw:
•Powerhead
•Extendable shaft with attached cutting head
•Guide bar
•Saw chain
•Blade cover
•Harness
•Screwdriver
•Allen wrench
•Two Allen screws
•Bar and chain oil
•Charger and power cord (if so equipped)
•Battery (if so equipped)
After removing the pole saw from the box,
inspect it carefully to ensure no damage has
occurred during shipping, and that no parts are
missing. If any parts are damaged or missing,
do not use the pole saw. Contact Oregon®
Cordless Tool System at .. to obtain
replacement parts.
Assembly
DANGER: To avoid serious personal
injury, do not operate the pole saw without
the extendable shaft, guide bar, saw chain,
and side cover properly assembled.
WARNING: A battery operated tool with
the battery pack inserted is always on and
can start accidentally. Remove the battery
pack from the pole saw before attaching
the extendable shaft, bar, and chain.
Assembling the Extendable Shaft
The extendable shaft fits into the motor
housing on the powerhead (Fig. ).
•It is important to ensure that the internal
drive shaft is properly seated. To ensure
proper seating, use a clean rag to pull the
aluminum drive shaft out from the fiberglass
pole—approximately  in ( cm). Using the
rag, turn the aluminum shaft while pushing
down slightly. This will allow the drive shaft to
properly seat on the shaft inside of the motor
housing. The cylindrical end of the drive shaft
will be completely hidden below the rim of the
motor housing once properly seated.
FIG. 6

Pole Saw Model PS250
Unpacking and Assembly
•After properly seating the aluminum drive
shaft, push down on the fiberglass pole so
that is slides into the opening of the motor
housing.
•Locate the provided Allen screws and place
them into the holes on the red cap. The red
cap on the motor housing acts as compression
fit to hold the pole in place.
•Use the supplied  mm Allen wrench to
partially tighten the Allen screws. Continue
tightening the screws by alternating between
screws until both of the screws are tight.
Note: You may need to press the red cap
tighter onto the motor housing to allow the
screws to make contact with the internal
threads.
Filling the Bar and
Chain Oil Reservoir
IMPORTANT: Bar and chain oil prevents
premature wear. Never operate the pole
saw if oil is not visible. Check oil level
frequently and fill as needed.
Bar and chain oil is required to properly
lubricate the guide bar and saw chain. The
pole saw is equipped with an automatic oiler
that deposits oil on the bar and chain when
running, keeping them properly lubricated. Use
Oregon® bar and chain oil for best results. It is
specially designed to provide low friction and
faster cuts. NEVER use oil or other lubricants
not specifically designed for use on the bar and
chain. This can lead to a clogged oil system,
which may cause premature wear of the bar
and chain.
•Place the pole saw on its side on a firm, flat
surface, so that the oil cap is on top (Fig. ).
•Clean any debris from the cap area.
•Remove the cap.
•Carefully pour the bar and chain oil into the
reservoir.
•Replace the cap and make sure oil is visible in
the reservoir.
If oil is not visible in the reservoir, additional bar
and chain oil is necessary.

Chain
WARNING: A battery operated tool with
the battery pack inserted is always on and
can start accidentally. Remove the battery
pack from the pole saw before attaching
the extendable shaft, bar, and chain.
Wear gloves and remove the battery. Make sure
the bar pad, drive sprocket, and tensioning pin
are free of debris.
•Adjust the tensioning screw as far back
toward the rear of the cutting head as it will
go.
•Place the guide bar on the bar pad by sliding
the bar slot over the alignment flange (Fig. ),
making sure the tensioning pin is inserted in
the bottom hole in the tail of the bar.
•Loop the saw chain onto the drive sprocket so
that the cutting edges of the teeth along the
top of the bar face away from the cutting head
(Fig. ).
•Feed the chain into the groove of the bar and
slide the bar away from the motor to remove
slack from the chain (Fig. ). Adjust the
position of the tensioning pin until it engages
the hole in the bar.
•Install the side cover, making sure the chain
catch is properly seated in its hole, then
lightly tighten the side cover knob (Fig. ).
IMPORTANT: The saw chain must be
properly tensioned before using. See
“Tensioning the Saw Chain”.

Tensioning the Saw Chain
WARNING: A battery operated tool with
the battery pack inserted is always on and
can start accidentally. Remove the battery
pack from the pole saw before attaching
the extendable shaft, bar, and chain.
Wear gloves.
•Remove the battery before tensioning.
•Loosen the side cover knob.
•Hold up the nose of the guide bar (Fig. ), and
tighten the tensioning screw.
•Tighten the tensioning screw until the lowest
cutters underneath the bar solidly contact the
bar (Fig. ).
•Tighten the side cover knob.
•Saw chain tension is correct when, with some
effort, a gloved hand can pull the chain
smoothly around the bar. The chain should
touch the underside of the bar rail (Fig. ).
After a short period of use, allow the chain to
cool and once again check the tension (remove
the battery first). Watch tension carefully
for the first half-hour of use and periodically
throughout the life of the chain, readjusting as
required when the chain and bar are cool to the
touch. Never tighten chain when it is hot.
Chain will stretch as a result of normal use,
but insufficient oil, aggressive use, or failure to
perform recommended maintenance can lead
to premature stretching.
