Specific Safety Rules
for Pole Pruners
WARNING: Do not operate near electrical
power lines. The unit has not been designed to
provide protection from electric shock in the
event of contact with overhead electric lines,
Consult local regulations for safe distances
from overhead electric power lines and ensure
that the operating position is safe and secure
before operating the saw chain pole pruner.
. Wear head, and eye protection and
personal protective equipment (PPE),
including correct clothing.
. Keep bystanders, especially children at a
safe distance during operation of the saw
chain pole pruner.
. 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 pruner may
result in serious personal injury.
. Carry the extended-reach pruner by the

pruner, always fit the saw chain device
cover. Proper handling of the extended-
reach pruner will reduce possible personal
injury from the saw chain.
. Hold the extended-reach pruner 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
pruner "live" and could give the operator an
electric shock.
. Keep cable away from cutting area. During
operation the cable may be hidden in
shrubs and can be accidentally cut by the
saw chain.
. Do not use the extended-reach pruner in

Pole Saw Model PS750-091
Extension Cords
Use a proper extension cord. ONLY use cords
listed by underwriters Laboratories (UL).
Other extension cords can cause a drop in
line voltage, resulting in a loss of power and
overheating of tool.
For this tool an AWG (American Wire Gauge)
size of a least -gauge is recommended for an
extension cord of -ft. or less in length. Use
-gauge for an extension cord of -ft.
Extension cords -ft. or longer are not
recommended. Remember, a smaller wire
gauge size has greater capacity than a larger
number (-gauge wire has more capacity than
-gauge wire; -gauge wire has more
capacity than -gauge). When in doubt use the
smaller number.
SECURING EXTENSION CORD
CAUTION: Keep the extension cord clear
of the work area. Position the cord so that it
will not get caught on bushes, hedges, tree
trunks, lawnmowers or other obstructions
while you are working with the pole saw.
WARNING: Check extension cords before
each use. If damaged replace immediately.
Never use tool with a damaged cord since
touching the damaged area could cause
electrical shock, resulting in serious injury.
Residual Risks
WARNING: Even when the unit is used
as prescribed it is not possible to eliminate all
residual risk factors. The following hazards may
arise in connection with the unit’s construction
and design:
• Damage to lungs if an effective dust mask
is not worn.
• Damage to hearing if effective hearing
protection is not worn.
• Health defects resulting from vibration
emission if the unit is being used over long
periods of time or not adequately managed

Important Safety Information
Pole Saw Model PS750-091
Reducing Kickback
Kickback can occur when the tip of the guide
bar touches an object or when the wood closes
in and pinches the saw chain inside of the cut.
Tip contact can kick the guide bar up and back
towards the operator.
WARNING: The danger of a kickback is
greatest when attempting to cut near or with
the guide bar tip. Always apply the saw as
flatly as possible in order avoid a loss of control
during operation.
Pinching the saw chain along the top of the
guide bar can push the bar rapidly towards the
operator. Either of these reactions may cause
a loss in control of the saw, increasing the
chances of serious personal injury.
Do not rely on the safety devices built into
the saw. Kickback is the result of tool misuse
and/or incorrect operating procedures. These
conditions can be minimized with the following
steps:
. Maintain a firm grip, with thumbs and
fingers encircling the pole saw handles.
Both hands should be on the saw with
your body and arms in a position to resist
kickback forces.
. Do not overreach and keep the work area
free from obstructions.
. Only use replacement bars and chains
specified by Senix. Replace dull blades as
necessary.
. Do not let the tip of the guide bar contact
any surfaces.
. Keep proper tension on the blade at
all times. Check the tension at regular
intervals.
. Cuts should only take place while the
chain is moving at full speed. Do not turn
the saw ON or OFF in the middle of a cut.
Use extreme caution when re-entering a
previous cut.
. Cut one branch at a time. Do not attempt
plunge or bore cuts. Watch for shifting logs
or other external forces that could close a
cut and pinch the chain.
. Make a precut on the opposite side of the
log to avoid the blade from being pinched
during operation as another safeguard
against kickback.
Sawing Techniques
WARNING: When removing branches, hold
the pole saw at an angle ranging from  to
° in order to avoid being struck by a falling
branch. The saw should never be operated
directly above head.
• Saw off the lower branches on the tree
first. By doing so, it is easier for the cut
branches to fall to the ground.
• At the end of the cut, the weight of the
saw suddenly increases for the user since
it is no longer being supported by a branch.
There is a risk of losing control of the saw,
so make sure to stay alert during the entire
sawing operation.
• Only pull the saw out of a cut while the
saw is running. By doing so, you prevent the
chain from jamming in the wood.
• Do not saw with the tip of the guide bar. Do
not saw into the branch formations (where
the tree branches outwards). This will
impede the tree’s ability to heal.
• For sawing off smaller branches, place the
stop face of the saw on the branch. This
prevents unwanted movements of the saw
at the beginning of the cut. While applying
light pressure, guide the saw through the
branch from top to bottom.
• For sawing off larger branches, first make
a relief cut. Saw through / of the branch
diameter from the bottom to top using the
top side of the guide bar. Then saw from
top to bottom for the other / using the
bottom side of the guide bar.
• Saw off longer branches in sections in order
to maintain control over the location of
impact.
• When working on an incline, always stand
above or to the side of the branch being
sawed. Hold the tool as close as possible
to your body. By doing so, you maximize
your balance.

Preparing for Use
DANGER: To avoid serious personal
injury, do not operate the pole saw
without the guide bar, saw chain, and side
cover properly assembled.
WARNING: Do not attempt to operate
the pole saw if any part is damaged or
missing.
WARNING: An electric power tool
that is plugged in can start accidentally.
Unplug the pole saw before preparing for
use or performing maintenance.
What’s in the box?
The pole saw requires some assembly before
use. These items ship with the pole saw:
•Pole Saw
•Blade cover
•Harness
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® at
.. to obtain replacement parts.
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.

•Tension the chain as described in “Tensioning
the Saw Chain” in the “Preparing for Use”
section of the manual.
IMPORTANT: The saw chain must be
properly tensioned before using. See
“Tensioning the Saw Chain” in the
“Preparing for Use” section of the
manual.
Tensioning the Saw Chain
WARNING: An electric power tool
that is plugged in can start accidentally.
Unplug the pole saw before preparing for
use or performing maintenance.
WARNING: If the chain is still loose
when the saw is at maximum tension,
replace the chain.
IMPORTANT: Only tension the saw chain
when the chain is cool. A hot chain may
contract and damage the guide bar or
chain as it cools.
Wear gloves.
•Unplug the pole saw before tensioning.
•Loosen the side cover release knob slightly,
but do not remove the side cover.
•Hold up the nose of the guide bar (Fig. ) and
turn the chain tensioning ring clockwise.
•Tighten the chain tensioning ring until the
lowest cutters underneath the bar solidly
contact the bar (Fig. ).
•Tighten the side cover release 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, unplug the pole saw and check the
tension again. 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 tension chain when it is hot.
Chain will stretch as a result of normal use,
however, insufficient oil, aggressive use, or
failure to perform recommended maintenance
can lead to premature stretching.

General Operation
DANGER: To avoid serious personal
injury, do not overreach and do not stand
on a ladder, stepstool, or any raised
position that is not fully secured.
DANGER: To avoid serious personal
injury, do not stand directly under the
limb being worked on. Stand away so that
the limb falls safely to the ground.
WARNING: To reduce the risk of injury,
always wear proper boots, gloves, head,
ear, and eye protection.
GRIP
Always grip the tool with both hands. For right-
handed operation, grasp the extendable shaft
comfortably with the left hand and the rear
handle with the right. Wrap fingers firmly
around each handle (Fig. ).
For left-handed operation, grasp the
extendable shaft comfortably with the right
hand and the rear handle with the left (Fig. ).
Hold the pole saw at about a ° angle (Fig. );
this is the least tiring work position and helps
ensure a safe distance from falling debris.

FOOTING
Stand with both feet on solid ground, with
weight evenly spread between them.
Hold the pole saw as close as possible to the
body to maintain control (Fig. ).
USING THE HARNESS
WARNING: Always attach the harness
when operating the pole saw. Do not carry
it only with your hands.
The harness helps to balance the pole saw and
distribute the weight of the pole saw across the
body, increasing comfort for extended use.
•Remove the nut and screw from the harness
attachment ring (Fig. ).
•Push the harness attachment ring onto the
pole between handle and grip with the holes
facing upwards. Secure the harness
attachment ring with screw and nut (Fig. ).
•Fit and adjust the length of the harness for
easy operation (Fig. ).
ADJUSTING THE SHAFT LENGTH
The pole saw features an extendable shaft that
allows greater reach into taller trees.
For ease of use, extend the shaft only as much
as necessary to reach the work safely.
•Unplug the pole saw.
•Turn the extension collar counter clock-wise
() until the shaft slides freely (Fig. ).
•Slide the shaft until it is the desired length ().
•Turn the extension collar clockwise to lock the
shaft in place.

STOPPING THE POLE SAW
The pole saw will automatically stop once the
trigger switch () is released. The trigger lock-
out () will have to be depressed and the
trigger switch squeezed to restart the pole
saw (Fig. ).
STARTING THE POLE SAW
WARNING: To reduce the risk of injury,
never defeat the interlock by taping,
wiring, or tying down the trigger lock-out.
If using the harness, put on the harness and
attach the harness clip to the attachment ring.
The pole saw is fitted with a trigger lock-out
feature. To start the pole saw, simply depress
the trigger lock-out () then fully press and
hold the trigger switch (). The trigger lock-out
can now be released (Fig. ).
NOTE: It is not necessary to maintain pressure
on the trigger lock-out once the trigger switch
is squeezed and the motor is running. The
trigger lock-out is a safety device to avoid
accidental start-up of the device.
Power Cord Use and Care
SELECTING AN EXTENSION CORD
Select an extension cord that is:
•Specifically labelled for outdoor use
•Of a wire size (AWG) heavy enough to carry
the current the full length of the cable
according to the table below
Select the gauge of extension cord based
on the desired length and the electrical
specifications found on the product label.
These are the recommended gauges based on
the length of cord.
CORD LENGTH (FT) MIN. WIRE SIZE
0–50 14 AWG (1.5 mm2)
51–100 12 AWG (3.0 mm2)
Make sure the insulation is free of cracks and
that the plugs on both ends are undamaged.
USING THE STRAIN RELIEF BRACKET
It is important to use the strain relief bracket
for two reasons:
•It saves wear on both the power cord and the
extension cord and their plugs.
•It prevents the pole saw from becoming
unplugged from the extension cord
accidentally.
To use the strain relief bracket, bend the
extension cord into a U-shape and put it
through the hole in the rear handle. Slide the
loop of cord over the hook and tug lightly until
snug (Fig. ).

Cutting
BASIC CUTTING
DANGER: To reduce the risk of shock,
never operate this tool near any wires or
cables which may be carrying electric
current.
Electricity can arc from one point to
another. Maintain a distance of at least
 ft ( m) between the pole saw and
any electrical line carrying live current or
branch contacting an electrical line.
Before working closer than  ft ( m),
contact electric utility and make sure the
current is turned off (Fig. ).
WARNING: To reduce the risk of injury,
wear proper boots, gloves, head, ear, and
eye protection.
WARNING: To reduce the risk of
electric shock, make sure the cord
insulation is intact and that the cord is in
a dry location where there is no danger of
it being cut or tripped over.
WARNING: To reduce the risk of injury,
always be sure of footing and hold the pole
saw firmly with both hands while the motor
is running.
WARNING: Falling limbs may bounce
when they hit the ground. Never work
under the limb being cut.
Observe all applicable national and municipal
rules and regulations for cutting.
Take frequent breaks to reduce the risk of
injury.
Before beginning to cut, make sure the saw
chain is properly tensioned, the automatic oiler
is functioning, and the chain is sharp.
Saw chains are made to cut wood only. Do not
use the pole saw to cut any other materials,
and do not allow the chain to come into
contact with dirt or rocks. These materials
are extremely abrasive and will wear away
protective plating from the chain in a very short
time.
Sharpen or replace the saw chain if any of these
conditions occur:
•The pressure required to make cuts increases
noticeably
•Wood chips coming off of the chain are very
fine or dust-like
Do not work with a dull chain as it will increase
the effort required to cut, cause jagged cuts,
and increase wear on the pole saw. Never force
a dull chain to cut.
Begin cutting by lightly pressing the guide bar
against the wood. Use only light pressure,
letting the saw do the work.

Operating the Pole Saw
Pole Saw Model PS750-091
Maintain a steady speed throughout the cut,
releasing pressure just before the end of the
cut.
If the saw stops suddenly when cutting, remove
the saw from the cut, then resume cutting
using lighter pressure on the limb.
PRUNING
•Clear the work area. Falling limbs may bounce
or “spring back” after they hit the ground,
so it is essential to keep the ground clear to
provide multiple retreat paths.
•Plan retreat paths before beginning to cut,
and make sure there are no obstructions.
Always know how to get out of the way of
falling branches.
•Make sure bystanders or helpers are a safe
distance from falling branches. Bystanders or
helpers should not stand directly in front of or
behind the operator. See Fig.  in “Work Area
Safety”.
•Maintain solid footing and hold the pole saw
firmly with both hands. Do not overreach.
Never climb a tree or ladder to reach high
limbs.
•Prune lower limbs before pruning higher ones.
•Allow the saw chain to achieve full speed
before cutting.
•Apply light pressure to the branch.
•For long limbs (Fig. ), cut the end of the limb
first () to relieve pressure from the limb, then
prune closer to the trunk ().
•Thick limbs (greater than  inches in diameter)
can splinter or pinch the chain when making a
single cut from the top. To avoid pinching or
splintering (Fig. ), first make one shallow
relief cut on the bottom surface of the limb (),
then cut the limb all of the way through from
the top of the limb ().
•After most of the limb has been removed,
make one smooth cut near the trunk (Fig. ).
