SAVE THESE INSTRUCTIONS
WARNING:
WARNING:
The danger of a kickback is greatest when attempting
to cut near or with the guide bar tip. Always apply the
saw as atly as possible in order avoid a loss of control
during operation.
When removing branches, hold the pole saw at an
angle ranging from 0 to 60° in order to avoid being
struck by a falling branch. The saw should never be
operated directly above head.
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:
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.
REDUCING KICKBACK
SAWING TECHNIQUES
1. Maintain a rm grip, with thumbs and ngers
encircling the pole saw handles. Both hands should
be on the saw with your body and arms in a position
to resist kickback forces.
2. Do not overreach and keep the work area free from
obstructions.
3. Only use replacement bars and chains specied by
Senix. Replace dull blades as necessary.
4. Do not let the tip of the guide bar contact any
surfaces.
5. Keep proper tension on the blade at all times. Check
the tension at regular intervals.
6. 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.
7. 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.
8. Make a precut on the opposite side of the log to
avoid the blade from being pinched during operation
as another safeguard against kickback.
• Saw off the lower branches on the tree rst. 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, rst make a relief
cut. Saw through 1/3 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 2/3 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.

INSTALL THE CHAIN BAR AND CHAIN
Disconnect the spark plug wire before performing
maintenance or assembly procedures.
Cutting edges on chain are sharp.
Use protective gloves when handling chain.
ALWAYS maintain proper chain tension. A loose chain
will increase the risk of kickback. A loose chain may
jump out of chain bar groove. This may injure operator
and damage chain. A loose chain will cause chain,
chain bar, and sprocket to wear rapidly. The chain
life of the saw chain mainly depends upon sufcient
lubrication and correct tensioning. Avoid tensioning the
chain if it is hot, as this will cause the chain to become
over tensioned when it cools down.
1. Place the saw body on a rm and level surface.
2. Using the supplied wrench, turn the bar adjustment
locking nut counter-clockwise to loosen it. Remove
the locking nut and cover.
5. Turn the chain tensioning screw clockwise to
preliminarily tighten the chain bar enough that it
stays in place. While holding the bar still, place the
cover back onto the saw. Make sure the tab properly
lines up with the slot on the body of the saw. Install
the locking nut. Using the supplied wrench, turn
the locking nut clockwise to tighten it. DO NOT
overtighten.
6. Check the chain tension by pulling the saw chain
away from the chain bar. A properly tensioned chain
should have roughly 1/8 inch (3 mm) of distance
between itself and the bar guide.
3. Wearing protective gloves, wrap the saw chain
around the chain bar, making sure that the teeth are
aimed in the direction of rotation. The chain should
be properly set in the slot running along the entire
outside edge of the chain bar.
4. Place the saw chain around the sprocket while lining
up the slot in the chain bar with the internal bolt at the
base of the saw and the chain tensioning pin in the
chain bar’s pin hole. The chain tensioning pin may
need adjustment to properly align with the hole in the
chain bar. Use a at-blade screwdriver to turn the
chain tensioning screw to adjust the location of the
pin until it ts in the chain bar.

SAW CHAIN LUBRICATION
FILLING THE OIL TANK
ADDING/CHECKING ENGINE OIL
ADD ENGINE OIL: INITIAL USE
CHECK ENGINE OIL: BEFORE EACH USE
The pole saw features automatic chain lubrication.
Never operate the pole saw without saw chain oil. The
use of the pole saw without enough saw chain oil will
damage the unit.
Only use SAE300 saw chain oil. Other oils will run the
risk of damaging the unit and voiding the warranty.
Take note of temperature conditions. Using the saw
at various temperatures requires the use of differing
oils. To ensure a sufcient layer of lubricant at lower
temperatures, use liquid oil (low viscosity).
7. If adjustments are needed, loosen the bar adjustment
locking nut one full turn.
8. To adjust the saw chain tension, turn the chain
tensioning screw. Turning the screw clockwise
increases the tension while turning it counter-
clockwise decreases tension. A properly tensioned
chain should have no sag and should only be able to
be pulled 1/8 inch (3 mm) away from the chain bar of
the saw.
9. Once the chain is properly tensioned, tighten the bar
adjustment locking nut. DO NOT over-tension the
chain: this will lead to excessive wear and reduces
the life of both the bar and chain.
1. Place the saw on a level surface. Clean the area
around the oil tank cap and then open it.
1. Unscrew the oil cap from the engine and remove.
2. Pour 60 ml of oil into the oil ll hole. Replace and
tighten the oil cap.
1. Separate the pole saw from the engine assembly.
2. Set engine assembly on a at level surface with shaft
parallel to surface.
3. Unscrew the oil cap and remove.
4. Lubricant level should fall within the top of the oil ll
hole (the top of screw thread).
5. If level is low, add engine lubricant until the uid level
rises to the top of oil ll hole (the top of screw thread).
NOTE: Do not overll.
6. Replace and tighten the oil cap.
2. Fill the oil tank with 4.02 oz. (120 ml) of saw chain
and bar oil.
3. Close the oil tank cap.
The saw chain must be tensioned properly in order to
ensure safe operation.
Make sure that no dirt gets into the oil tank to prevent
clogging in the oil nozzle.
Attempting to start the engine before it has been
properly lled with lubricant will result in equipment
failure not covered by the warranty.
Do not overll. Overlling the crankcase may cause
excessive smoke, oil loss, and engine damage.
Operation of this equipment could create sparks that
can start res around dry vegetation. A spark arrestor
may be required. The operator should contact local
re agencies for laws or regulations relating to re
prevention requirements.
Engine lubricant has a major inuence on engine
performance and service life. This unit is shipped
without engine lubricant.

OPERATION
Do not use any attachments or accessories not
recommended by the manufacturer of this product. The
use of attachments or accessories not recommended
can result in serious personal injury.
Gasoline is extremely ammable. Ignited vapors may
explode. Always stop the engine and allow it to cool
before lling the fuel tank. Do not smoke while lling the
tank. Keep sparks and open ames at a distance from
the area.
Remove the fuel cap slowly to avoid injury from fuel
spray. Never operate the unit without the fuel cap
securely in place.
Add fuel in a clean, well-ventilated outdoor area. Wipe
up any spilled fuel immediately. Avoid creating a source
of ignition for spilled fuel. Do not start the engine until
fuel vapors dissipate.
DO NOT USE E85 FUEL IN THIS UNIT. It has been
proven that fuel containing greater than 10% ethanol
will likely damage this engine and void the warranty.
Use a fuel additive, such as STA-BIL Fuel Stabilizer or
an equivalent, to inhibit corrosion and minimize gum
deposits. Add 0.8 oz. (23 ml) of fuel additive per gallon
of fuel, according to the instructions on the container.
NEVER add fuel additives directly to the unit’s fuel tank.
Gasoline and its vapors are highly ammable and
explosive. To prevent serious personal injury and
property damage, handle it with care. Keep away from
ignition sources and open ames, handle outdoors only.
Pour fuel outdoors where there are no sparks or ames.
Slowly remove the fuel cap after stopping the engine.
Do not smoke while fueling. Wipe spiled fuel from unit.
Move at least 3 m (10 ft) away from the fueling source
before starting engine.

FUELING THE UNIT
The use of old fuel is the most common cause of
performance problems. Use only fresh, clean unleaded
gasoline.
This unit has a four-cycle engine. DO NOT mix oil with
gasoline.
Today’s fuels are often a blend of gasoline and
oxygenates such as ethanol, methanol or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1%
water in the fuel can make fuel and oil separate, forming
acids when stored. ALWAYS use fresh fuel (less than
30 days old) with less than 10% ethanol. Dispose of old
fuel according to federal, state and local regulations.
If using a blended fuel:
Always use fresh unleaded gasoline.
Use the fuel additive STA-BIL®or an equivalent.
1. Remove the fuel tank cap by turning counterclockwise.
Rest the cap on a clean surface.
2. Carefully pour fuel into the tank until fuel reaches the
base of the tank spout. Avoid spillage.
3. Immediately replace fuel cap and hand tighten by
turning it clockwise. Wipe up any spilled fuel.
NOTE: Visually inspect to see if fuel level is low. If fuel is
low, rell with unleaded fuel carefully without overlling
and tighten the fuel tank cap immediately.
Engine housing can become hot during pole saw
operation. Do not rest or place your arm, hand, or any
body part against the engine housing.
Extended contact with the engine housing can result in
burns or other injuries.

PREPARATION
Before each use, check the following items to ensure
safe working conditions.
POLE SAW: Before beginning work, inspect the pole
saw for damage to the housing, the saw chain and the
guide bar. Never use a damaged machine.
OIL TANK: Check the ll level of the oil tank. Also
check whether there is sufcient oil available while
working. Never operate the saw if there is no oil or the
oil level is not visible in order to prevent damage to
the pole saw. On average, an oil lling is sufcient for
the operating time of the fuel tank (depending on the
duration of pauses and the density of the workpiece).
SAW CHAIN: Check the tension of the saw and the
condition of the blades. The sharper the saw chain is,
the easier and more manageable operations will be.
The same applies to chain tension.
Check the tension every 10 minutes of operation
to maximize safety. New saw chains in particular
are subject to changes due to the heat created by
operation.
PROTECTIVE CLOTHING: Make sure to wear the
appropriate close- tting protective clothing such as
hainsaw-protective pants, gloves and safety shoes.
Wear a safety helmet with integrated hearing protection
and a face guard to provide protection against falling
and recoiling branches.
