IMPORTANT SAFETY INSTRUCTIONS
When using electric gardening appliances, basic safety precautions should always be followed
to reduce the risk of fire, electric shock, and personal injury, including the following:
READ ALL INSTRUCTIONS
Power Cord Safety
WARNING! - To reduce the risk of electric
shock, use only with an extension cord
intended for outdoor use, such as an
extension cord of cord type
SW-A, SOW-A, STW-A, STOW-A, SJW-A,
SJOW-A, SJTW-A. or SJTOW-A.
1. Extension Cord - Make sure your extension cord
is in good condition. When using an extension
cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized
extension cord will cause a drop in line voltage
resulting in loss of power and overheating.
2. Ground Fault Circuit Interrupter (GFCI)
protection should be provided on the
circuit(s) or outlet(s) to be used for the
gardening appliance. Receptacles are
available having built-in GFCI protection and
may be used for this measure of safety.
3. Do not Abuse Cord - Do not carry appliance
by cord or yank it to disconnect from receptacle.
Keep cord from heat, oil, and sharp edges.
4. To reduce the risk of electric shock, this
appliance has a polarized plug (one blade is
wider than the other) and will require the use
of a polarized extension cord. The appliance
plug will fit into a polarized extension cord only one
way. If the plug does not fit fully into the extension
cord, reverse the plug. If the plug still does not fit,
obtain a correct polarized extension cord.
5. A polarized extension cord will require the use
of a polarized wall outlet. This plug will fit into the
polarized wall outlet only one way. If the plug does
not fit fully into the wall outlet, reverse the plug. If the
plug still does not fit, contact a qualified electrician
to install the proper wall outlet. Do not change
the equipment plug, extension cord receptacle,
or extension cord plug in any way. This design is

Vibration Hazard
This appliance vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating appliances regularly
or for an extended period should first be
examined by a doctor and then have regular
medical check-ups to ensure medical problems
are not being caused or worsened from use.
Pregnant women or people who have impaired
blood circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or Raynaud’s
Disease should not use this appliance. If you
feel any symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration
effects on the user.
4. Use appliances with the lowest vibration when
there is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip appliance as lightly as possible
(while still keeping safe control of it).
Let the appliance do the work.
7. To reduce vibration, maintain the appliance
as explained in this manual. If any abnormal
vibration occurs, stop use immediately.
General Safety
1. Stop working when you feel tired or exhausted.
Make regular breaks to rest.
2. Keep all parts of the body away from saw chain.
Do not remove cut material or hold material to
be cut when saw chain is moving. Make sure the
switch is off when clearing jammed material.
3. Hold Pole Saw by insulated gripping surfaces
only, because the saw chain may contact
hidden wiring or its own cord. Saw chains
contacting a “live” wire may make exposed
metal parts of the garden power tool “live” and
could give the operator an electric shock.
4. Keep power cord away from cutting area.
During operation the power cord may be hidden in
shrubs and can be accidentally cut by the blade.
5. Before use, make sure the saw chain
is not contacting anything.
6. Hold Pole Saw with both hands on the handle.
7. Do not operate Pole Saw from within a tree.
Operation of tool while up in a tree
may result in personal injury.
8. Keep proper footing and operate the garden
power tool only when standing on fixed,
secure and level surface. Slippery or unstable
surfaces such as ladders may cause a loss of
balance or control of the garden power tool.
9. When cutting a limb that is under tension, be
alert for spring back. When the tension in the
wood fibers is released, the limb may strike the
operator and/or throw the tool out of control.
10. Do not use for bore cutting, felling or bucking.
11. Keep bystanders and other workers at
least 50 feet from the work area.
12. Do not operate within 50 feet of electrical lines.
13. Use extreme caution when cutting brush
and saplings. The slender material may catch
the saw chain and be whipped around.
14. Carry Pole Saw with tool switched off and
away from your body. Proper handling of
the Pole Saw will reduce the likelihood of
accidental contact with the moving saw chain.

15. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
16. Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions.
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Kickback can be avoided by taking
proper precautions as given below:
a. Maintain a firm grip, with thumbs and fingers
encircling the Pole Saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the
operator, if proper precautions are taken.
Do not let go of the garden power tool.
b. Do not overreach. This helps prevent unintended
tip contact and enables better control of the
garden power tool in unexpected situations.
c. Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause
chain breakage and/or kickback.
d. Follow the manufacturer’s sharpening
and maintenance instructions for the
saw chain. Decreasing the depth gauge
height can lead to increased kickback.
17. Keep handles dry, clean, and
free from oil and grease.
18. Use for cutting wood only. Do not use for cutting
plastic, masonry or non-wood building materials.
19. Do not touch guide bar tip to any object.
Tip contact may cause guide bar to move
suddenly upward and backwards.

and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of
our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS.
To take advantage of this warranty, the product or part must be returned to us with transportation charges
prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise.
If our inspection verifies the defect, we will either repair or replace the product at our election or we may
elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will
return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
