GENERAL POWER TOOL SAFETY WARNINGS
IMPORTANT SAFETY WARNINGS
2
WARNING: Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term ―power tool‖ in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock
if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk of
electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the risk
of electric shock.
Personal safety
Stay alert, watch what you are doing and use
common sense when operating a power tool. Do not
use a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in
serious personal injury.
Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal
injuries.
Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch on
invites accidents.
Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
Power tool use and care
Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained
users.
Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
3
When servicing a power tool, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance
instructions may create a risk of shock or injury.
CHAIN SAW SAFETY WARNINGS
Keep all parts of the body away from the saw chain
when the chain saw is operating. Before you start the
chain saw, make sure the saw chain is not contacting
anything. A moment of inattention while operating chain
saws may cause entanglement of your clothing or body
with the saw chain.
Always hold the chain saw with your right hand on the
rear handle and your left hand on the front handle.
Holding the chain saw with a reversed hand configuration
increases the risk of personal injury and should never be
done.
Hold the power tool by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring . Saw chains contacting a live wire may make
exposed metal parts of the power tool live and could give
the operator an electric shock.
Wear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet is
recommended. Adequate protective clothing will reduce
personal injury by flying debris or accidental contact with
the saw chain.
Do not operate a chain saw in a tree. Operation of a
chain saw while up in a tree may result in personal injury.
Always keep proper footing and operate the chain saw
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 chain saw.
When cutting a limb that is under tension be alert for
spring back. When the tension in the wood fibres is
released the spring loaded limb may strike the operator
and/or throw the chain saw out of control.
Use extreme caution when cutting brush and saplings.
The slender material may catch the saw chain and be
whipped toward you or pull you off balance.
Carry the chain saw by the front handle with the chain
saw switched off and away from your body. When
transporting or storing the chain saw always fit the
guide bar cover. Proper handling of the chain saw will
reduce the likelihood of accidental contact with the moving
saw chain.
Follow instructions for lubricating, chain tensioning
and changing accessories. Improperly tensioned or
lubricated chain may either break or increase the chance
for kickback.
GENERAL POWER TOOL SAFETY WARNINGS
Service
Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain saw for
cutting plastic, masonry or non-wood building
materials. Use of the chain saw for operations different
than intended could result in a hazardous situation.
Causes and operator prevention of kickback:
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.
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
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 personal injury. Do not rely
exclusively upon the safety devices built into your saw. As a
chain saw user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
Maintain a firm grip, with thumbs and fingers
encircling the chain 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 chain saw.
Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and
enables better control of the chain saw in unexpected
situations.
Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to increased
kickback.

HEDGE TRIMMER SAFETY WARNINGS
DANGER – Keep hands away from blade. Contact with
blade will result in serious personal injury.
Use both hands when operating the hedge trimmer.
Using one hand could cause loss of control and
result in serious personal injury.
Keep all parts of the body away from the cutter blade.
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. Blades coast after turn
off. A moment of inattention while operating the hedge
trimmer may result in serious personal injury.
Carry the hedge trimmer by the handle with the cutter
blade stopped. Proper handling of the hedge trimmer will
reduce possible personal injury from the cutter blades.
Hold the power tool by insulated gripping surfaces
only, because the cutter blade may contact hidden
wiring or its own cord. Cutter blades contacting a ―live‖
wire may make exposed metal parts of the power tool
―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 blade.
WARNING – Only use with handle and guard properly
assembled to hedge trimmer. The use of the hedge trimmer
without the proper guard or handle provided may result in
serious personal injury.
EXTENSION CORD. Make sure your extension cord is in
good condition. When using an extension cord, be sure it is
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. The following
table shows the correct size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next
heavier gage. The smaller the gage number, the heavier the
cord.
WARNING: Use out door extension cords marked SW-A,
SOW-A, STW-A, SJW-A, or SJTW-A. These cords are rated
for outdoor use and reduce the risk of electric shock.
DOUBLE INSULATION—Double Insulation is a concept in
safety in electric power tools, which 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.
NOTE: 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.
It is possible to tie the extension cord and power
cord in a knot to prevent them from becoming
disconnected during use. Make the knot as
shown, then connect the plug end of the power
cord into the receptacle end of the extension
cord. This method can also be used to tie two
extension cords together.

POLARIZED PLUGS—To reduce the risk of electric shock,
this equipment has a polarized plug (one blade is wider than
the other). This equipment must be used with a suitable
polarized 2 wire or 3 wire extension cord. Polarized
connections will fit together only one way. Make sure that the
receptacle end of the extension cord has large and small
blade slot widths. If the plug does not fit fully into the
extension cord, reverse the plug. If it still does not fit obtain a
suitable extension cord. If the extension cord does not fit fully
into the outlet, contact a qualified electrician to install the
proper outlet. Do not change the tool plug or extension cord in
any way.
CHECK DAMAGED PARTS – Before further use of the tools,
a guard or other part that is damaged should be carefully
checked to determine that it will operate properly and perform
its intended function. Check for alignment of moving parts,
binding of moving parts, breakage of parts, mounting and any
other condition that may affect its operation. A guard or other
part that is damaged should be properly repaired or replaced.

13. When the tension knob is fully tightened, the chain is the
tightest. To minor adjust the chain tension, loosen the tension
knob and turn it counter-clockwise slightly until the chain is
correctly tensioned.
NOTE: The chain is correctly tensioned when there is no sag on the
underside of the guide bar, then chain is snug, but it can be turned by
hand without binding.
NOTE: A new chain tends to stretch, check chain tension
frequently and tension as required.
14. After a period of usage, the chain may get loose. To tighten the
chain, loosen the tension knob by turning counter-clockwise,
repeat 12 and 13 to correctly adjust the chain tension.
CHAIN TENSION AND MAINTENANCE
CHAIN TENSION
Stop the motor before setting the chain tension. Make sure the
tension knob is loosened to finger tight, turn the tension knob clockwise to tension the chain. A cold chain will be correctly tensioned
when there is no slack on the underside of the guide bar, the chain is
snug, but it can be turned by hand without binding.
Chain must be re-tensioned whenever the flats on the drive links hang
out of the bar groove.
During normal saw operation, the temperature of the chain will
increase. The drive links of a correctly tensioned warm chain will hang
approximately .050 in. (1.25mm) out of the bar groove. (Fig. 17) Be
aware that chain tensioned while warm, may be too tight upon cooling. Check the ―cold tension‖ before next use.
NOTE: A new chain tends to stretch, check chain tension frequently
and tension as required.
Approx. .050 (1.25mm)
CHAIN MAINTENANCE
CAUTION: Disconnect the saw from the power supply and make sure
the chain has stopped before you do any work on the saw.
For smooth and fast cutting, chain needs to be maintained properly.
The chain requires sharpening when the wood chips are small and
powdery, the chain must be forced through the wood during cutting,
or the chain cuts to one side. During maintenance of your chain
remember:
- Improper filing angle of the side plate can increase the risk
of severe kickback.
- Raker (depth gauge) clearance.
Too low increases the potential for kickback.
Not low enough decreases cutting ability.
- If cutter teeth have hit hard objects such as nails and stones, or
have been abraded by mud or sand on the wood, have service
dealer sharpen chain.
NOTE: Inspect the drive sprocket for wear or damage when
replacing the chain. If signs of wear or damage are present in the
areas indicated, have the drive sprocket replaced by a qualified
individual.
HOW TO SHARPEN THE CUTTERS
Be careful to file all cutters to the specified angles and to the same
length, as fast cutting can be obtained only when all cutters are
uniform.
Wear gloves for protection. Properly tension the chain prior to
sharpening. Refer to ―Chain Tension Section‖ earlier in this manual.
Do all of your filing at the midpoint of the bar.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth. Do not let the file dip
or rock. Using light but firm pressure, stroke towards the front corner
of the tooth. (Fig. 18)

Lift file away from the steel on each return stroke.
Put a few firm strokes on every tooth. File all left hand cutters in one
direction. Then move to the other side and file the right hand cutters
in the opposite direction. Occasionally remove filing from the file with
a wire brush. (Fig. 19)
DEPTH GAUGE CLEARANCE (Fig. 22)
The depth gauge should be maintained at a clearance of .025 in.
(0.6 mm). Use a depth gauge tool for checking the depth gauge
clearances.
Every time the chain is filed, check the depth gauge clearance.
Use a flat file and a depth gauge jointer to lower all gauges uniformly.
Depth gauge jointers are available in .020 in. to .035 in. (0.5 mm to
0.9 mm). Use a .025 in. (0.6 mm) depth gauge jointer. After lowering
each depth gauge, restore original shape by rounding the front. Be
careful not to damage adjoining drive links with the edge of the file.
Depth gauges must be adjusted with the flat file in the same direction
the adjoining cutter was filed with the round file. Use care not to
contact cutter face with flat file when adjusting depth gauges.
WARNING: Improper chain sharpening increases the potential of
kickback.
WARNING: Failure to replace or repair damaged chain can cause
serious injury.
WARNING: The saw chain is very sharp, always wear protective
gloves when performing maintenance to the chain.
TOP PLATE FILING ANGLE (Fig. 20)
Correct 30 degrees – File holders are marked with guide marks to
align file properly to produce top plate angle.
Less than 30 degrees – for cross cutting.
More than 30 degrees – feathered edge dulls quickly.
SIDE PLATE ANGLE (Fig. 21)
Correct – 80 degrees produced automatically if correct diameter file is
used in file holder.
Hook – ―Grabs‖ and dulls quickly. Increases potential of kickback.
Results from using a file with a diameter too small, or file held too
low.
Backward Slope – Needs too much feed pressure, causes
excessive wear to bar and chain. Results from using a file with a
diameter too large, or file held too high.

1. To adjust the sawing angle, pressing the angle adjustment button.
2. Turn the saw to the desired angle.
3. The angle can be kept between -20 and 60 degrees.
Before you start the unit, make sure the pole/chain saw is not
contacting any object.
STARTING THE POLE/CHAIN SAW
Push the safety button in with your thumb and then squeeze the
switch trigger with your fingers. Once the tool is running, you can
release the safety button. To turn the tool OFF, release the switch
trigger. (Fig. 23)
WARNING: To guard against injury, observe the following:
Read instruction manual before using.
Save instruction manual.
Keep hands away from blades.
Keep hands on handles. Don’t overreach.
A good, firm grip on the pole/ chain saw with both hands will help you
maintain control. Grip the rear handle with your right hand whether
you are right or left handed. Wrap the fingers of your left hand over
and around the front handle when using the chainsaw, or around the
pole shaft when using the pole saw. A firm grip together with positioning handle against your body will help you maintain control of the saw.
Don’t let go.
WARNING: Do not operate pole saw in a tree, on a ladder, or on a
scaffold; this is extremely dangerous.
CAUTION: Chain coasts after pole saw is turned off. Do not use under wet conditions.
Use extreme caution when cutting small size brush, saplings or limbs
under tension, because slender and tense material may catch the saw
and be whipped toward you, pull you off balance or spring back.
CHAIN BRAKE
When using the chainsaw, in case an emergency stop is necessary,
use the back of your hand to push hard the hand guard forward.
Chain will stop immediately. (Fig. 24)
CAUTION: Failure to lubricate the chain will cause damage to the bar
and chain. Use only a good quality bar and chain oil or, if not available, unused SAE 30 weight motor oil may be substituted. One minute
of use will consume approx. 0.15 fl. oz. (5ml) of oil.
NOTE: It is normal for oil to seep from the chainsaw cutting head
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.
OPERATING
10
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 chain 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 result is a
lightening fast, reverse reaction which kicks the guide bar up and
back toward the operator. If the chain 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 chain saw
user, you should take several
steps to keep your cutting
jobs free from accident or
injury.
The following precautions should be followed to minimize
kickback:
1. Always grip the pole and/or handles firmly with both hands when
unit is running. When using the chainsaw, place your right hand
on the rear handle and your left hand on the front handle with
your thumbs and fingers encircling the chainsaw handles. When
using as a pole saw, place one hand on the pole and your other
hand on the rear handle with your thumbs and fingers encircling
the pole and handle. A firm grip together with positioning handle
against your body will help you maintain control of the saw if
kickback occurs.
2. Make sure that the area in which you are cutting is free from
obstructions. Do not let the nose of the guide bar contact a log,
branch, fence or any other obstruction that could be hit while you
are operating the saw.
3. Always cut with the unit running at full speed. Fully squeeze the
throttle trigger and maintain a steady cutting speed.
4. Wear non-slip gloves for maximum grip protection.
Cut lower branches first to allow the top branches more room to fall.
Work slowly, keeping both hands on the saw with a firm grip.
Maintain secure footing and balance.
WARNING: To protect yourself from electrocution, maintain a min. of
50 ft. (15m) from over head electrical lines.
WARNING:Keep bystanders at least 50 ft. away.
WARNING: Do not cut trees near electrical wires or buildings.
WARNING: Do Not use the pole saw with any type of accessory or
attachment. Such usage might be hazardous.

PROPER CUTTING STANCE
Weight should be balanced with both feet on solid ground.
Keep left arm with elbow locked in a ―straight arm‖ position to
withstand any kickback force when using pole saw. Your right hand
should be gripping the handle and positioned firmly against body for
added support.
Your body should always be to the left of the chain line.
BASIC CUTTING PROCEDURE
Do not use the pole saw to fell saplings. Use the chain saw without
the pole attachment.
Small trees up to 6-7 inches in diameter are usually cut in a single
cut. Large tree limbs require notch cuts. Notch cuts determine the
direction the tree will fall.
WARNING: If the tree limb starts to fall in the wrong direction, or if
the saw gets caught or hung up during the fall, leave the saw and
save yourself.
WARNING: Periodically glance at the top of the tree during the
back-cut to assure the tree limb is going to fall in the desired direction.
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 wood with the saw in the
―off‖position.
Squeeze the trigger and let the chain accelerate to full speed before
entering the cut.
Always hold the saw firmly with both hands.
Keep the unit 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 in
serious injury.
Do not put pressure on the saw at the end of the cut.
When felling the top of a small tree,keep everyone a safe distance
from the cutting area.During felling operations, the safe distance
should be at lease twice the height of the largest trees in the felling
area.If the tree makes contact with any utility line, the utility company
should be notified immediately.
Always cut with both feet on solid ground to prevent being pulled or
knocked off balance.
Do not extend arms above shoulder level when operating the pole saws.
Do not cut above chest height when using the chain saw.
FELLING A TREE
When bucking and felling operations are being performed by two or
more persons, at the same time, the felling operation should be
separated from the bucking operation by a distance of at least twice
the height of the tree being felled. Trees should not be felled in a
manner that would endanger any person, strike any utility line or
cause any property damage. If the tree does make contact with any
utility line, the utility company should be notified immediately.
Before felling is started, consider the force and direction of the wind, the
lean and balance of the tree, and the location of large limbs. These
things influence the direction in which the tree will fall. Do not try to fell a
tree along the line different from its natural line of fall.
The saw operator should keep on the uphill side of the terrain as the
tree is likely to roll or slide downhill after it is felled.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree
where felling cuts are to be made.
NOTCHED UNDERCUT– Cut a notch about 1/3 diameter of the tree,
perpendicular to the direction of the fall. Make the cuts of the notch so
they intersect at a right angle to the line of fall. This notch should be
cleaned out to leave a straight line. To keep the weight of the wood off
the saw, always make the lower cut of the notch before the upper cut.
WARNING: Do not fell trees during periods of high wind or heavy
precipitation. Wait to do your cutting until the hazard has ended.
WARNING: Do not cut down trees having an extreme lean or large
trees that have rotten limbs, loose bark, or hollow trunks. Have these
trees pushed or dragged down with heavy equipment , then cut them
up.
FELLING BACK-CUT
The back-cut is always made level and horizontal, and at a minimum of
2 inches (5cm) above the horizontal cut of the notch.
Never cut through to the notch. Always leave a band of wood between
the notch and back-cut (approximately 2 inches (5cm) or 1/10 the
diameter of the tree). This is called ― hinge‖ or ―hinge wood‖. It controls
the fall of the tree and prevents slipping or twisting or shoot-back of the
tree off the stump.
This saw is not designed to fell large diameter tree tops, or tree trunks.

WARNING: Check the tree for damaged or dead branches that could fall
and hit you during felling.
Before any cuts are started, pick your escape route (or routes in case
the intended route is blocked); clear the immediate area around the tree
and make sure there are no obstructions in your planned path of retreat.
A clear path of safe retreat is approximately 135 degrees from planned
line of fall. The retreat path should extend back and diagonally to the
rear of the expected line of fall.(Fig. 26)

CUTTING INSTRUCTIONS
As the tree limbs starts to fall, stop the saw and immediately retreat
along the cleared path. Watch the action in case something falls your
way. Be alert for overhead limbs or branches that may fall and watch
your footing.
WARNING: Never cut through to the notch when making a back-cut.
The hinge controls the fall of the tree, this is a section of wood between the notch and back-cut.(Fig. 27)
BUCKING
Bucking is the term used for cutting a fallen tree to the desired log
length.
Always make sure your footing is secure and your weight is
distributed evenly on both feet.
Cut only one log at a time, Support small logs on a saw horse or
another log while bucking.
Keep a clear cutting area. Make sure that no objects can contact the
guide bar nose and chain during cutting, this can cause kickback.
When bucking on a slope, always stand on the uphill side of the log.
When ―Cutting through‖, to maintain complete control of the pole saw,
release the cutting pressure near the end of the cut without relaxing
your grip on the pole saw handles. Do not let the chain contact the
ground After completing the cut, wait for the saw chain to stop before
you move the pole saw. Always stop the motor before moving from
tree to tree.
BUCKING LOGS UNDER STRESS
When the log is supported along its entire length, it should be cut from
the top or over-bucking.
When the log is supported on one end, cut 1/3 diameter from the
underside or under-bucking. Then make the finishing cut by
over-bucking to meet the first cut.
As the log is being cut, it will tend to bend The saw can become
pinched or hung in the log if you make the first cut deeper than 1/3 of
the diameter of the log.
Give special attention to logs under stress to prevent the bar and
chain from pinching.
OVERBUCKING - Begin on the top side of the log with the button of
the saw against the log; exert light pressure downward. Note that the
saw will tend to pull away from you. (Fig. 28)
UNDER-BUCKING - Begin on the under side of the log with the top of
the saw against the log; exert light pressure upward. During
under-bucking, the saw will tend to push back at you. Be prepared for
this reaction and hold the saw firmly to maintain control. (Fig. 28)
LIMBING (Fig. 29)
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the pole saw with a firm grip.
Always make sure your footing is secure and your weight is distributed
evenly on both feet.
Leave the larger support limbs under the tree to keep the tree off the
ground while cutting.
Limbs should be cut one at a time. Remove the cut limbs from the work
area often to help keep the work area clean and safe.
Branches under tension should be cut from the bottom up to avoid binding the pole saw.
Keep the tree between you and the pole saw while limbing. Cut from the
side of the tree opposite the branch you are cutting.
WARNING: Never climb into a tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to lose
your balance or control of the saw.
PRUNING (Fig. 30)
Pruning is trimming limbs from a live tree.
Work slowly, keep both hands on
the pole saw with a firm grip and the
handle positioned firmly against your
body for added control and ease of
handling. Always make sure your
footing is secure and your weight is
distributed evenly on both feet.
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 limb further out to reduce
the weight. This prevents stripping
the bark from the main member.
Make first cut six inches from tree trunk as possible on underside of limb
stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of
stub.
Move two to four inches farther out on limb. Make second cut from
above limb. Continue cut until you cut limb off.
Make third cut as close to tree trunk as possible on underside of limb
stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of
stub.
Make fourth cut directly above third cut. Cut down to meet third cut. This
will remove limb stub.
SPRINGPOLES
A spring pole is branch, or sapling which is bent under tension by other
wood so that it springs back if the wood holding it is cut or removed.
WARNING: Watch out for spring poles, they are dangerous, They could
result in severe or fatal injury.

bent or cracked, handles broken or if you see any other condition that
may affect the product’s operation, it must be repaired before putting
it back into use. Call our customer service help line at 1-800-3135111 for assistance.
CAUTION: Do not at any time let brake fluids, gasoline, petroleum
based products, penetrating oils, etc., come in contact with plastic
parts. They contain chemicals that can damage, weaken or destroy
plastic.
Make sure the unit is detached from the power supply, then use only
mild soap and a damp cloth to clean the tool. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment should be performed by a
qualified individual using identical replacement parts only.
Ensure that the plastic bar covers are in place when storing.
For smooth and fast cutting, chain needs to be maintained properly.
The chain requires sharpening when the wood chips are small and
powdery, the chain must be forced through the wood during cutting,
or the chain cuts to one side. Refer to instructions earlier in this manual for instructions on properly sharpening the chain.
LUBRICATION SYSTEM FOR POLE/CHAIN SAW
The chain is automatically lubricated.
Use only new bar and chain oil or unused SAE 30 weight motor oil
may be substituted. Never use wasted oil, low quality oil, or insufficient oil. This could damage the pump; the bar and the chain which
may result in serious personal injury.
Check oil level before each work session, refill if less than ¼ full.
If the lubrication system does not work properly, check if the oil filter
and all oil-ways are clean and free from obstructions. If it is still not
working, call our customer service help line at 1-800-313-5111 for
assistance.
GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, reverse it on the saw to
distribute the wear for maximum bar life. The bar should be cleaned
every day of use and checked for wear and damage.
The cutting blades are made from high quality, hardened steel and
with normal usage, they will not require re-sharpening. However, if
you accidentally hit a wire fence, stones, glass or other hard objects,
you may put a nick in the blade. There is no need to remove this nick
as long as it doesn’t interfere with the movement of the blade. If it
does interfere, make sure the unit is detached from the power supply
and use a fine toothed file or sharpening stone to remove the nick.
Fertilizers and other garden chemicals contain agents which greatly
accelerate the corrosion of metals Do not store the tool on or
adjacent to fertilizers or chemicals.
LUBRICATE BLADES - Stop the unit and disconnect the power cord.
Then remove any debris on blades. Apply a light machine oil along
the edge of the top and bottom blade supports. Make sure handles
remain clean and dry.
MAINTENANCE
SIDE-TRIMMING HEDGES—Begin at the bottom and sweep up.
(Fig. 39)
Do not force the trimmer through dense growth. A slight back and
forth sawing action may ease the cutting of larger, more dense
growth. If the trimmer begins to slow down, reduce the rate of speed
at which you are trying to cut. If the trimmer becomes jammed,
immediately turn trimmer off. Disconnect trimmer from the power
supply and remove the jammed debris from the cutting blades.
TRIMMING INSTRUCTIONS
14
LEVEL HEDGES - To obtain exceptionally level hedges, a piece of
string can be stretched along the length of the hedge as a guide. (Fig.
38)
CAUTION: Do not use the 18 inch trimmer for cutting stems greater
than .7‖. Use the trimmer only for cutting normal shrubbery found
around houses and buildings.
TRIMMING NEW GROWTH—A wide, sweeping motion, feeding the
blade teeth through the twigs is most effective. A slight downward tilt
of the blade in the direction of the motion gives the best cutting.
USING THE HEDGE TRIMMER
Feathering or burring of the bar rails is a normal process of bar wear.
Such faults should be smoothed with a file as soon as they occur.
A bar with any of the following faults should be replaced.
- Wear inside the bar rails which permits the chain to lay over
side ways.
- Bent guide bar
- Cracked or broken rails
- Spread rails
In addition, guide bars with a sprocket at their tip must be lubricated
frequently with a grease syringe to extend the guide bar life. Using a
grease syringe, lubricate weekly in the lubricating hole.
