Operating Instructions
ASSEMBLY
1. Using hand, turn the locking knob on the end cover counterclockwise to
remove the end cover (Fig. 1).
TIP: When replacing the chain, slide on the cutting bar sheath temporarily for
added protection.
2. Lay out the new saw chain in a loop and straighten any kinks. THE SHARP
SIDE OF THE TEETH MUST FACE AWAY FROM YOU IN TH DIRECTION
OF THE CHAIN ROTATION INDICATED ON THE GUIDE BAR.
3. Starting at the tip, mount the chain drive links into the bar groove, leaving a
loop at the back of the bar. The chain will loosely fit until it is placed on the
sprocket. (Fig. 2).
NOTE: Make certain of the direction of the chain. If the chain is mounted
backwards, the saw will vibrate abnormally and will not cut.
4. Hold the chain in position on the bar and place the loop around the sprocket.
Fit the bar flush against the mounting surface so that the bar studs are in the
long slot of the bar (Fig. 3).
5. Use one hand to lift the bar and chain, then use the other hand to attach the
end cover, and turn the knob clockwise to tight en the end cover. (Fig. 4).
6. Check the tension of the chain, if loose, turn the tension adjustment knob
clock- wise to tighten the chain. (Fig. 4).
NOTE: If the chain is too tight, it will not rotate. Loosen the tension adjustment
knob slightly. Ensure that the chain can be rotated by hand without binding.
NOTE: A new chain tends to stretch; check the chain tension frequently, and
adjust tension as required.

ATTACH THE 1O" POLE SAW CUTTING HEAD
1. Hold the rear handle by one hand, and attach the pole saw cutting head with
the other hand. Ensure the terminal in the rear handle are correctly matched
(Fig. 5).
2. Then pull the fixing connector upward and tighten the thread by hand.
ATTACH THE SHOULDER STRAP
1. Move the locking knob together with the loop to the position you desire, then
tighten the locking knob by hand.
2. Attach the shoulder strap to the hooks (Fig. 6).
OPERATION
STARTING AND STOPPING
CAUTION! Before starting the saw, remove the oil tank cap and add bar and
chain oil to the top of the oil level window (Fig. 7).

7
NOTE: Your 10" pole saw is equipped with an automatic oil pump for bar and
chain oiling. You must add bar and chain oil or your 10" pole saw will not
function.
Starting, stopping, and restarting an electric motor repeatedly within a few
seconds can generate a great deal of heat and damage the motor. To protect
the life of your 10" pole saw, always wait at least five seconds after stopping
before restarting the saw.
A good, firm grip on the tool using both hands will help you maintain control.
When using the 10" pole saw, place one hand on the front handle grip and the
other hand on the rear handle with your thumbs and fingers encircling the pole
and handle. A firm grip combined with proper positioning of the handle against
your body will help you maintain control of the saw. Do not let go of the 10"
pole saw while it is in operation.
NOTE: It is normal for oil to seep from the saw when not in use. To prevent
seepage, empty the oil tank after each use. When storing the unit for a long
period of time (3 months or longer), be sure the chain is lightly lubricated; this
will prevent rust on the chain and bar sprocket.
WARNING! Kickback may occur when the moving chain contacts an object at
the upper portion of the tip of the guide bar or when the wood closes in and
pinches the chainsaw in the cut (Fig. 8). Contact at the upper portion of the tip
of the guide bar can cause the chain to dig into the object and stop the chain
for an instant. The result is a lightning-fast reverse reaction, which kicks the
guide bar up and back toward the operator. If the chainsaw is pinched along
the top of the guide bar, the guide bar can be driven rapidly back toward the
operator. Either of these reactions can cause loss of saw control, which can
throw the operator off balance and result in serious injury. Do not rely
exclusively upon the safety devices built into the saw. As a user, you should
take several precautions to keep your cutting jobs free from accident or injury.

1. Prior to each cutting session, run through the daily checklist.
2. Connect the 10" pole saw to a working 120 V outlet using a heavy-duty
outdoor extension power cord.
3. Make a loop in the power cord and push it up through the hole in the handle
and around the cord restraint hook (Fig. 9), then connect the extension co「d to
the appliance cord.
4. To turn the tool ON, push and hold the safety lock button (located on the
rear handle) with your thumb and then squeeze the trigger with your fingers.
Once the tool is running, you can release the safety lock button (Fig. 9).
5. To turn the tool OFF, release the
trigger switch (Fig. 9).
NOTE: Do not press the trigger switch until you are ready to make a cut.
ADJUSTING THE TELESCOPING POLE
1. Disconnect the 10" pole saw from the power supply.
2. press the lock button with one hand, and release the thread sleeve with the
other hand in the direction indicated by the icon (Fi g. 10).

9
3. Extend the pole to the desired length (Fig. 11).
NOTE: Push poles toward each other to shorten the pole or pull them away
from each other to lengthen the pole. Only extend the pole to the minimum
length required to reach the limb to be cut.
4. Tighten the thread sleeve by hand in the direction indicated by the icon on
the part (Fig. 12), and ensure that the pole is secure.
ADJUSTING THE MULTI-ANGLE HEAD
The chainsaw head can be rotated for different cutting angles from 0° to 30°,
totaling three positions, 0°, 15° and 30°.
1. Disconnect the 10" pole saw from the power supply.
2. Push the angle adjustment button from both sides with your index finger and
thumb, then use the other hand to adjust the pole saw head to your desired
position (Fig. 13).

10
3. Release the button and make sure the head is securely in place.
NOTE: Failure to pro perly secure the head adjustment button may result in
personal injury and /or property damage.
CUTTING TIPS
PROPER CUTTING STANCE
•Balance your weight with both feet on solid ground.
•Your body should always be to the left of the chain line.
WARNING!
•Never stand directly under the limb you are cutting. Always position yourself
out of the path of falling debris.
•Always wear head, eye, foot and body protection. Wearing body protection
Helps reduce the risk of injury when operating this unit.
•Never stand on a ladder or other unstable support while using the 10" pole
saw. Always avoid any position which can cause you to lose your balance and
cause severe injury.
•Keep other persons at least 50 feet (15ml from the work area. Distractions
can cause you to lose control.
•Electrocution Hazard. To prevent shock, do not operate within 50 ft. (15m) of
overhead electrical lines. Always check surrounding area for hidden electrical
lines.
•Do not extend 1O" pole saw switch handle above shoulder height.
•The most typical cutting application is to position the unit at an angle of 60°
or less depending on the specific situation (Fig.14). As the angle of the 10"
pole saw shaft to the ground increases, the difficulty of making the first cut
(from the underside of limb) increases.

11
BASIC CUTTING PROCEDURE
This unit is designed for trimming small branches and limbs up to 7.5" (19 .1
cm) in diameter depending on the wood type. Practice cutting a few small
limbs using the following technique to get the "feel" of using the saw before you
begin a major sawing operation.
•Take the proper stance in front of the tree with the saw OFF (Fig . 24).
•Squeeze the trigger and let the chain accelerate to full speed before entering
the cut.
•Keep the saw running the entire time you are cutting; maintain a steady
speed.
•Allow the chain to cut for you; exert only light downward pressure. If you
force the cut, damage to the bar, chain, or unit can result.
•PUSH and PULL - This reaction force is always opposite to the direction the
chain is moving when it is in contact with the wood. Thus, the operator must be
ready to control the PULL when cutting on the bottom edge of the bar, and
PUSH when cutting along the top edge.
•Do not put pressure on the saw at the end of the cut.
PRUNING
Pruning is the process of trimming limbs from a live tree.
•Remove long branches in several stages.
•Cut lower branches first to allow the top branches more room to fall.
•When pruning trees, it is important not to make the finishing cut next to the
main limb or trunk until you have cut off the farthest lying limb. This will reduce
the weight and prevent stripping the bark from the main member.

12
•Under cut the branch 1/3 through for your first cut. Your second cut should
over cut to drop the branch off (Fig. 15). Be prepared to balance the weight of
the 10" pole saw when the limb falls.
•Now make your finishing cut from the topside of the branch smoothly and
neatly against the main member so the bark will grow back to seal the wound .
•Release the trigger ON/OFF switch as soon as the cut is completed.
Failure to follow proper cutting procedures will result in the bar and chain
binding and becoming pinched or trapped in the limb.
LIMBING
Limbing is the process of removing branches from a fallen tree.
•You should cut limbs one at a time. Remove the cut limbs from the work area
often to help keep the work area clean and safe.
•Cut branches under tension from the bottom up to avoid binding the 10" pole
saw.
•Keep the tree between you and the 10" pole saw while limbing. Cut from the
side of the tree opposite the branch you are cutting.
IF THE SAW BECOMES PINCHED OR TRAPPED
1. Wait for the blade to stop, wait five minutes for the saw to cool, unplug the
power cord, and wear gloves to protect your hands f「om the chain teeth.
2. If you can reach the limb from the ground, lift the limb while holding the saw.
This should release the "pinch" and free the saw.
3. If the saw is still trapped, call a professional for assistance.
MINIMIZE KICKBACK
Kickback may occur when the moving chain contacts an object at the upper
portion of the tip of the guide bar or when the wood closes in and pinches the
10" pole saw in the cut. Contact at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and stop the chain for an instant. The

13
result is a lightning-fast reverse reaction, which kicks the guide bar up and
back toward the operator. If the 10" pole saw is pinched along the top of the
guide bar, the guide bar can be driven rapidly back toward the operator.
Either of these reactions can cause loss of saw control, which can result in
serious injury. Do not rely exclusively upon the safety devices built into the saw.
As a 10" pole saw user, you should take several steps to keep your cutting jobs
free from accident or injury.
Take the following precautions to minimize kickback:
•Before you start the unit, make sure the 10" pole saw is not contacting any
objects.
•Always grip the pole and handle firmly with both hands when the unit is
running. Place one hand on the pole and your other hand on the molded
handle with your thumbs and fingers encircling the pole and handle. A firm grip
combined with proper positioning of the handle against your body will help you
maintain control of the saw if kickback occurs.
•Make sure that the area in which you are cutting is free from obstructions .
•Do not let the kickback danger zone area of the guide bar contact a log,
branch, fence, or any other obstruction that could be hit while you are
operating the 10" pole saw (Fi g. 8).
•Always cut with the unit running at full speed. Fully squeeze the ON/OFF
trigger and maintain a steady cutting speed.
•Wear nonslip gloves for maximum grip and protection.
•Extend the pole only to the length required to reach the limb cut. Do not
extend the rear handle above waist height.
Maintenance and Storage
Maintenance
MOTOR COOLING
To avoid overheating and damage to the motor, always keep the cooling air
vents clean and free of sawdust and debris.
CHAIN TENSION
Check the chain tension before using the saw when the chain is cold. The

14
correct tension of a cold chain is when there is no slack on the underside of the
guide bar; the chain is snug, but you can rotate it by hand without binding.
During normal saw operation, the temperature of the chain will increase. The
drive links of a correctly tensioned warm chain will hang approximately
0.050 in. (1.25 mm) out of the bar groove (Fig. 16). Be aware that a chain
tensioned while warm, may be too tight upon cooling. Check the " cold tension"
before next use. The chain must be retensioned whenever the flats on the
drive links hang out of the bar groove (Fig. 16).
NUTS AND SCREWS
Periodically check that all the nuts and screws are tightened securely. Check
that the cam-lock that controls the telescoping pole is intact and in proper
working order.
CHAIN SHARPENING
Sharpening is necessary when:
•The sawdust looks like dust
•The cut is not straight
•Cutting becomes more difficult
•Vibrations increase
An authorized service center will sharpen the chain using the right tools to

15
ensure minimum removal of material and even sharpness on all the cutting
edges.
If you sharpen the chain yourself, use special round-section files with the right
diameter depending on the type of chain (see "Chain Maintenance Table").
You need a certain amount of skill and experience to avoid damaging the
cutting edges.
Sharpen the chain as follows (Fig. 17):
•Secure the bar firmly, with the chain mounted, in a suitable vice.
•Tighten the chain if it is loose.
•Mount the file in the guide and then insert it in the tooth at a constant angle
from the cutting edge.
•Sharpen in a forward motion a few times and repeat this on all the cutting
edges facing the same way (right or left).
•To move the chain forward, use a screwdriver.
•Turn the bar over in the vice and repeat on all the other cutting edges.
•Check that the depth limiter tooth does not stick out farther than the
inspection tool and file any projecting parts with a flat file, rounding off the
edges (Fig. 17).
•After sharpening, remove all traces of filing and dust and lubricate the chain
in an oil bath. Replace the chain whenever:
- The length of the cutting edges decreases to 5 mm or less;
- There is too much play between the links and the rivets.

16
GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, turn it over on the saw to distribute
the wear for maxim um bar life. Feathering or burring of the bar rails is a
normal process of bar wear. You should smooth such faults with a file as soon
as they occur.
Replace a bar with any of the following faults
•Wear inside the bar rails permitting the chain to lay over sideways
•Bent guide bar
•Cracked or broken rails
•Spread rails
Turn the saw over, check the underside of the guide bar, and make sure that
the lubrication holes and chain groove are free from impurities.
You can purchase replacement parts for your 10" pole saw by call at
1-833-818-4111.
CHAIN SPROCKET
Regularly check the condition of the sprocket
and replace it when wear exceeds 0.5 mm (Fig .18).
Do not mount a new chain with a worn sprocket or vice versa.
CLEANING
Use only mild soap and a damp cloth to clean the 10" pole saw. Never let any
liquid get inside the motor housing and NEVER immerse any part of the saw
housing in liquid.

17
STORAGE
•Ensure that the guide bar cover is in place when storing .
•Do not store the 10" pole saw near chemicals, such as fertilizers or other
harsh solvents. Do not expose the plastic parts of the unit to brake fluids,
gasoline, petroleum-based products, penetrating oils, or the like. These
products are often highly corrosive and may cause permanent damage,
weaken, or destroy the plastic parts of your 10" pole saw.
•When not in use, your 10" pole saw should be stored indoors in a dry and
high or locked-up place, out of the reach of children.
