GENERAL SAFETY RULES
Warning –When using an electric pole saw, basic safety precautions should always be
followed to reduce the risk of fire, electric shock, and injury to persons, including the
following:
READ ALL INSTRUCTIONS
Make sure you read and understand all instructions. Improper use of this pole saw can cause severe injury
or death from fire, electrical shock, and body contact with moving chain, on falling wood.
BEFORE OPERATING SAW
1. Read and understand this owner’s manual before operating pole saw.
2. Watch what you are doing. Use common sense. Do not operate saw when you are tired.
3. Use pole saw for cutting wood only. Do not use pole saw for purpose not intended. Do not use for
cutting plastic, masonry, etc.
4. Only well-instructed adults should operate pole saw. Never allow children to operate pole saw.
5. Use only electrical voltage noted on model plate of pole saw.
6. Use only extension cords marked for outdoor use.
7. Do not operate pole saw
•While under the influence of alcohol, medication, or drugs
•In rain or in damp or wet areas
•Where highly flammable liquids or gases are present
•If saw is damaged, adjusted wrong, or not fully and securely assembled
•If trigger does not turn saw on and off. Chain must stop moving when you release trigger. Have
faulty switch replaced by authorized service center.
•While in a hurry
•While in tree or on a ladder unless trained to do so
8. Wear snug-fitting clothes when operating pole saw. Do not wear loose clothing or jewelry. They can
get caught in moving saw chain.
9. Wear the following safety gear when operating pole saw.
•Heavy-duty gloves (wear rubber gloves when working outdoors)
•Steel-toed safety footwear with non-skid soles
•Eye protection such as safety glasses, goggles, or face screen
•Hard hat
•Ear mufflers or ear plugs
•Hair covering to contain long hair
•Face or dust mask (if working in dusty areas)
10. Before cutting, always provide the following:
•Clear work area
•Secure footing
•Planned retreat path from falling tree
11. Inspect tree before cutting down. Make sure there are no dead limbs or branches that may fall on you.
12. To reduce the risk of electric shock, this saw has a polarized plug (one blade is wider than the other).
This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet of your
extension cord, reverse the plug. If it still does not fit, a polarized extension cord will be necessary.
Do not change the plug in any way.
WHILE OPERATING SAW

5
Stay alert. Use common sense while operating pole saw.
Keep work area clean. Cluttered areas invite injuries.
Be aware of extension cord while operating pole saw. Be careful not to trip over cord. Keep cord
away from chain and operator at all times.
Keep children, animals, and bystanders away from pole saw and extension cord. Only pole saw user
should be in work area.
Do not cut down a tree unless you are trained or have expert help.
If two or more persons perform bucking and felling operations at the same time, provide plenty of
distance between operations. Provide distance of at least twice the height of tree being felled.
Grip pole saw firmly with both hands. Never operate pole saw with one hand. Never use hand guard
as handle.
Keep finger off trigger until ready to make cut.
Before starting pole saw, make sure chain is not touching anything.
To guard against electrical shock, avoid body contact with grounded objects such as pipes, fences,
and metal posts.
Keep all parts of body away from chain when saw is running.
Do not force pole saw while cutting. Apply light pressure. It will do the job better and safer at the rate
for which it was intended.
Cut small brush and saplings with extreme care. Slender material may catch in chain and be whipped
toward you. This could also pull you off balance.
When cutting limb or tree trunk that is under tension, use extreme caution. Be alert for wood
springing back. When wood tension is released, limb could spring back and strike operator causing
severe injury or death.
Carry pole saw from one place to another
•With saw stopped and unplugged
•By holding front handle (never use hand guard as handle)
•With finger off trigger
•With guide bar and chain to rear
KICKBACK SAFETY PRECAUTIONS
Warning –Kickback may occur when the nose or tip of the guide bar touches on object, or
when the wood closes in the cut. Tip contact in some cases may cause a lightning fast reverse
reaction, kicking the guide bar up and back towards the operation. Pinching the saw chain
along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these
reactions may cause you to lose control of the saw which could result in serious injury to user.
Kickback is the name given to a sudden, rapid upward movement of the saw cutting mechanism in an
upward arc towards the operator. Kickback occurs when the upper quadrant of the bar nose comes in
contact with a solid object or is pinched. The rotational force of the chainsaw can be reversed in the
opposite direction of the chain movement. This may fling the bar up and back in an arc towards the
operator. Serious injury or even death can result from contact between the moving saw chain and the
operator.
The best protection against injury due to kickback is to avoid situations that can cause kickback:
Hold the chainsaw firmly with both hands and maintain a secure grip.
Be aware of the location of the bar nose at all times while cutting.

6
Never bring the nose of the guide bar in contact with any object. Never cut limbs with the nose of the
guide bar. Be especially careful when cutting saplings, brush and small hard limbs that may easily
pinch the cutting chain.
Don’t cut above shoulder height. Don’t overreach or use the chainsaw while standing on a ladder or
tree.
Never use the chainsaw one-handed.
Use extreme caution when entering a previous cut.
Do not attempt plunge cuts if you are not familiar with this cutting technique.
Stand to the side of the cutting path of the chainsaw.
Cut with a correctly sharpened, properly tensioned chain at all times.
Save these instructions. It is your guide to safe and proper operation of this pole saw.
ELECTRICAL INFORMATION
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools that eliminates the need for the usual
three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor
components with protecting insulation. Double insulated tools do not need to be grounded.
WARNING: The double insulated system is intended to protect the user from shock resulting
from a break in the tool’s internal insulation. Observe all normal safety precautions to avoid
electrical shock.
NOTE: Servicing a product with double insulation requires extreme care and knowledge of the system.
This should be performed only by a qualified service technician. For service, we suggest you return the
product to your nearest authorized service center for repair. Always use original replacement parts
intended for your particular model of tool when servicing.
WARNING: This tool is for outdoor use only. Do not expose to rain or use in damp locations.
Guidelines for using extension cords
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 cord will cause a drop in line
voltage resulting in loss of power and overheating. The table below shows the correct size to be used
according to cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

Not Recommended
Make sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be
protected with a 15 Amp time-delayed fuse. Before connecting the motor to the power line, make sure the
switch is in the OFF position and the electric current is rated the same as the current stamped on the motor
nameplate. Running at a lower voltage will damage the motor.
WARNING: This tool must be grounded while in use to protect the operator from electric shock.

OPERATION
Adjusting pole length
The pole saw has a telescoping pole assembly that will extend from 71 inches (fully retracted) to 94.5
inches (fully extended).
An adjusting knob near handle is used to hold the pole in
position at any extended length.
1. To extend the pole, loosen the adjusting knob. Pole
will slide freely.
2. Pull inner tube out to desired length of extension.
Note: only extend pole to minimum length required to reach limb
that is being cut.
3. To lock pole in position, tighten adjusting knob.
Turn on the pole saw
1. Use both hands to grip Pole Saw. Use only designated grip areas when operating Pole Saw. Use firm
grip. Thumbs and fingers must wrap around Pole Saw handle and pole.
2. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet.
3. When ready to make a cut, press in trigger switch lock-out and squeeze trigger switch. This will turn
pole saw on.
Warning - Never stand directly under the limb you are trimming. Always position yourself
out of the path of falling debris.
Warning - Never stand on a ladder or other type of unstable support while using the pole saw.
Warning - Do not use pole saw near cable, electric power or telephone lines. Maintain a
minimum clearance of 10 feet from all power lines.
Warning - Keep other persons from cutting end of pole saw an d at a safe distance from work
area.

MAINTENANCE
Change saw chain
1. Remove the screw and turn Sprocket Locking Knob counterclockwise to remove the guide bar cover.
2. Move the chain tensioning pin fully back towards the sprocket
using the chain tension screw. (See direction arrow)
3. Place the guide bar onto the bar studs so that the chain tensioning pin fits into the hole in the guide
bar.
4. Install chain over clutch and place around the sprocket and guide bar.
5. Make sure the chain cutters on top of the guide bar face in the direction that the chain runs.
6. Install guide bar cover. Tighten the sprocket locking knob finger tight.
7. Adjust saw chain tension by first holding the bar nose up and turning the chain tension screw
clockwise until saw chain touches the bottom of the guide bar.
8. Tighten the sprocket cover locking nut using the wrench provided, keeping the guide bar nose up
while tightening the nut.
9. Pull the saw chain around the guide bar by hand to check for tight spots. Saw chain should move
freely but not sag. If too tight loosen the guide bar nuts and adjust using the chain tension screw.
10. Tighten the guide bar cover by turning the sprocket locking knob and using a screwdriver to tighten
screw.
WARNING - Never try to run the chainsaw without sprocket cover securely tightened.

Caution: Proper saw chain tension is extremely important. If saw chain is too tight, the guide bar and saw
chain will be quickly damaged. If the saw chain is too loose, it may get out of the guide bar groove and
cause an injury.
Note: A new chain will stretch so adjust the tension after a few cuts. Watch saw chain tension carefully
for the first half hour of cutting.
Guide bar and oil holes
Clean guide bar before use. Follow instructions for removing and
installing guide bar and saw chain. Remove guide bar and clean
groove of the guide bar with a small screwdriver. Clean oil holes
with a wire. Check the sprocket and the clutch and clean the bar
mount area before installing the bar. Guide bar with sprocket nose
should be lubricated with grease using a lubricating syringe. Invert
the symmetrically shaped guide bar every 8 working hours or each
time the chain is removed to ensure uniform wear. Check the bar
rails frequently for wear and remove burs and square up the rails
using a flat file. Clean the Oiler port on the saw every time the saw
chain and guide bar are removed.
Sprocket
A damaged drive sprocket will cause premature wear or damage of the chainsaw.
Check the sprocket when installing a new chain. When outer diameter of sprocket is worn 0.5mm (0.020”)
or more, replace it. Always clean sprocket, clutch and bar mount area before installing guide bar.
Saw chain sharpening
It is advisable to have professional shops sharpen saw chains. It is beyond the expertise of the typical
home owner to sharpen saw chains. An improperly sharpened saw chain will not cut effectively, require
more physical effort, and cause high vibrations and a higher rate of wear.
