Kickback safety precautions
Warning: Kickback can lead to dangerous loss of control of the
chain saw and result in serious or fatal injury to the saw
operator or to anyone standing close by. Always be alert.
Rotational kickback and pinch-kickback are major chain saw
operational dangers and the leading cause of most accidents.
KICKBACK may occur when the NOSE or TIP of the guide bar
touches an object, or when wood closes in and pinches the
saw chain in the cut. Tip contact in some cases may cause a
lightning-fast reverse reaction, kicking the guide bar up and
back toward the operator.
PINCHING the saw chain along the BOTTOM of the guide bar
may PULL the saw forward away from the operator. PINCHING
the saw chain along the TOP of the guide bar may PUSH the
guide bar rapidly back toward the operator.
Any of these reactions may cause you to lose control of the
saw, which could result in serious personal injury.
Beware of the following:
Rotary recoil (Fig. 1)
A = Recoil distance
B = Recoil reaction zone
Impact/Jamming recoil and pulling reactions (Fig. 2)
A = Pull
B = Solid objects
C = Push
To prevent pulling reactions, place the wood you wish to cut
against the claw stop. Use the claw stop as a pivot point
during cutting (Fig. 2).
Safety Instructions
Warning: When using petrol tools, basic safety precautions,
including the following, should always be followed to reduce
the risk of serious personal injury and/or damage to the unit.
Read all these instructions before operating this product and
save these instructions.
1 DO NOT operate a chain saw with one hand! Serious injury
to the operator, helpers, bystanders, or any combination of
these persons may result from one-handed operation.
A chainsaw is intended for two-handed use.
2 Do NOT use the saw if you are tired, ill or under the
influence of alcohol and/or drugs.
3 Use safety footwear, snug-fitting clothing, protective
gloves, and eye, hearing and head protection devices.
4 Use caution when handling fuel. Move the chainsaw at
least 10 feet (3m) from the fueling point before starting
the engine.
5 DO NOT allow other persons to be near when starting or
cutting with the chain saw. Keep bystanders and animals
out of the work area.
6 DO NOT start cutting until you have a clear work area,
secure footing, and a planned retreat path from the
falling tree.
7 Keep all parts of your body away from the saw chain when
the engine is running.
8 Before you start the engine, make sure that the saw chain
is not contacting anything.
9 Carry the chain saw with the engine stopped, the guide
bar and saw chain to the rear, and the exhaust away from
your body.
10 NEVER use a chainsaw which is damaged, incorrectly set
or incompletely and loosely assembled. Make sure that the
chainsaw stops when the chain brake is applied.
11 Shut off the engine before setting the chain saw down.
12 Use extreme caution when cutting small size brush and
saplings because slender material may catch the saw chain
and be whipped toward you or pull you off balance.

13 When cutting a limb that is under tension, be alert for
springback so that you will not be struck when the
tension in the wood fibers is released.
14 Keep the handles dry, clean, and free of oil or
fuel mixture.
15 Operate the chain saw only in well-ventilated areas.
16 DO NOT operate a chain saw in a tree unless you have
been specifically trained to do so.
17 All chain saw service, other than the items listed in the
user manual safety and maintenance instructions, should
be performed by competent chain saw service personnel.
18 When transporting your chain saw, use the appropriate
guide bar scabbard.
19 DO NOT operate your chain saw near or around
flammable liquids or gases whether in or out of doors.
An explosion and/or fire may result.
20 Do not fill fuel tank, oil or lubricate when the engine of
chain saw is running.
21 USE THE RIGHT TOOL: Cut wood only. Do not use the
chain saw for purposes for which it was not intended.
For example, do not use the chain saw for cutting plastic,
masonry, or non building materials.
22 The engine will create toxic exhaust fumes as soon as the
engine is started. Never work in enclosed rooms or in
rooms with poor ventilation.
Note: The chainsaw is designed for occasional use by home
owners, garden owners and campers and is for general work
such as stump grubbing, cutting firewood, etc. It is not
designed for lengthy use. If it is used for a lengthy period,
the vibrations it causes in the hands of the user may result
in circulation problems (white finger syndrome).
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. If the bar tip contacts, it may cause
a lightning-fast 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 loose 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.
1 With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
2 Keep a good firm grip on the saw with both hands,
the right hand on the rear handle, and the left hand
on the front handle, when the engine is running.
Use a firm grip with thumbs and fingers encircling
the chain saw handles. A firm grip will help you
reduce kickback and maintain control of the saw.
Don’t let go.
3 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, or any other
obstruction which could be hit while you are
operating the saw.
4 Cut at high engine speeds.
5 Do not overreach or cut above shoulder height.
6 Follow manufacturer’s sharpening and maintenance
instructions for the saw chain.
7 Only use replacement bars and chains specified by
the manufacturer or the equivalent.
Safety features (Fig. 3)
2 LOW KICKBACK SAW CHAIN helps significantly
reduce kickback, or the intensity of kickback,
due to specially designed depth gauges and
guard links.
5 CHAIN BRAKE LEVER / HAND GUARD protects the
operator’s left hand in the event it slips off the front
handle while saw is running.

position to start or restart engine.
11 SAFETY TRIGGER prevents accidental
acceleration of the engine. Throttle trigger
(19) cannot be squeezed unless the safety
latch is depressed.
20 CHAIN CATCHER reduces the danger of injury in
the event saw chain breaks or derails during
operation. The chain catcher is designed to
intercept a whipping chain.
Note: Study your saw and be familiar with its parts.
Proper use
The chain is designed exclusively for sawing wood. You may
only fell trees if you have received the appropriate training.
The manufacturer cannot be held liable for damage caused
by improper or incorrect usage.
Please note that our equipment has not been designed for
use in commercial, trade or industrial applications. Our
warranty will be voided if the machine is used in commercial,
trade or industrial businesses or for equivalent purposes.

Installation
Important: Do not start the engine until the saw is
fully assembled.
Important: Wear protective gloves at all times when handling
the chain.
Fit the chain bar
To ensure that the bar and the chain are supplied with oil,
USE ONLY THE ORIGINAL BAR. The oiling hole (Fig. 4/Item
A) must be kept clear of dirt and any build-up of residue.
1 Make sure the Chain brake lever is pulled back
into the DISENGAGED position (Fig. 5)
2 Remove the two bar fastening nuts (B). Remove
the cover (Fig. 6).
Important: When assembling for the first time, the material
fitted to provide protection during transportation
(Fig. 7/Item 24) must be removed first.
3 Using a screwdriver, run the adjustment screw (D)
COUNTERCLOCKWISE until the TANG (E)
(projecting prong) is to the end of its travel toward

8To install saw chain
1 Spread chain out in a loop with cutting edges (A)
pointing CLOCKWISE around loop (Fig. 9).
2 Slip the chain around the sprocket (B) behind the
clutch (C). Make sure the links fit between the
sprocket teeth (Fig. 10).
3 Guide the drive links into the groove (D) and
around the end of the bar (Fig. 10).
Note: The saw chain may droop slightly on the lower part
of bar. This is normal.
4 Pull the chain bar forward until the chain is closely
seated. Make sure that all the drive links are in the
groove of the bar.
5 Fit the clutch cover and fasten it with 2 screws.
Make sure that the pivot (Fig. 7/Item E) fits into
the chain bar (Fig. 8/Item G). The chain must
not slip off the bar when you do this. Tighten the
two nuts by hand and then follow the instructions
for adjusting the tension in ADJUSTING THE
CHAIN TENSION.
Saw chain tension adjustment
Proper tension of saw chain is extremely important
and must be checked before starting, as well as
during any cutting operation.
Taking the time to make needed adjustments to the
saw chain will result in improved cutting performance
and prolonged chain life.
Warning: Always wear heavy duty gloves when handling saw
chain or making saw chain adjustments.
1 Before adjusting the chain tension screw you must
slacken the 2x retaining nuts. Otherwise this will
damage tension screw.
2 Hold nose of guide bar up and turn adjustment
screw (D) CLOCKWISE to increase chain tension.
Turning screw COUNTERCLOCKWISE will decrease
amount of tension on chain. Ensure the chain fits
snugly all the way around the guide bar (Fig. 11).

3 After making adjustment, and while still holding
nose of bar in the uppermost position, tighten the
bar retaining nuts securely. Chain has proper
tension when it has a snug fit all around and can be
pulled around by gloved hand.
Note: If chain is difficult to rotate on guide bar or if it binds,
too much tension has been applied. This requires minor
adjustment as follows:
4 Loosen the bar retaining nut so they are finger
tight. Decrease tension by turning the bar
adjustment screw COUNTERCLOCKWISE slowly.
Move chain back and forth on bar. Continue to
adjust until chain rotates freely, but fits snugly.
Increase tension by turning bar adjustment
screw CLOCKWISE.
5 When saw chain has proper tension, hold nose of
bar in the uppermost position and tighten the bar
retaining nut securely.
Caution: A new saw chain stretches, requiring adjustment
after as few as 5 cuts. This is normal with a new chain, and
the interval between future adjustments will lengthen quickly.
Caution: If the saw chain is TOO LOOSE or TOO TAUT, the
drive wheel, chain bar, chain and crank shaft bearing will
suffer premature wear. Fig. 12 shows the correct tension A
(when cold) and tension B (when warm). Fig. C shows a
chain that is too loose.

Getting Started 4
Before starting the machine
Chain break mechanical test
Your chain saw is equipped with a Chain brake that reduces
possibility of injury due to kickback. The brake is activated if
pressure is applied against brake lever when, as in the event
of kickback, operator’s hand strikes the lever. When the brake
is actuated, chain movement stops abruptly.
Warning: The purpose of the chain brake is to reduce the
possibility of injury due to kickback; however, it cannot provide
the intended measure of protection if the saw is operated
carelessly. Always test the chain brake before using your saw
and periodically while on the job.
To test chain brake
1 The Chain brake is DISENGAGED (chain can move)
when BRAKE LEVER IS PULLED BACK AND
LOCKED (Fig. 13).
2 The chain brake is ENGAGED (the chain is locked)
when the brake lever is pulled forward and the
mechanism (Fig. 14/Item A) can be seen. It should
not be possible to move the chain (Fig. 14).

Note: The brake lever should snap into both positions. If
strong resistance is felt, or lever does not move into either
position, do not use your saw. Take it immediately to a
professional Service Center for repair.
Fuel and lubrication
Fuel
Use regular grade unleaded fuel mixed with 50:1 custom
2-cycle engine oil for best results.
Mixing fuel
Mix fuel with 2 cycle oil in an approved container. Shake
gently and ensure thorough mix.
Warning: Never use straight fuel in your unit. This will cause
permanent engine damage and void the manufacturer’s
warranty for that product. Never use a fuel mixture that has
been stored for over 90 days.
Warning: If 2-cycle lubricant is to be used, it must be a
premium grade oil for 2-cycle air cooled engines mixed
at a 50:1 ratio. Do not use any 2-cycle oil product with a
recommended mixing ratio of 100:1. If insufficient lubrication
is the cause of engine damage, it voids the manufacturer’s
engine warranty for that occurrence.
Recommended fuels
Some conventional fuels are being blended with oxygenates
such as alcohol or an ether compound to meet clean air
standards. Your engine is designed to operate satisfactorily
on any fuel intended for automotive use including
oxygenated fuel. It is recommended to use unleaded petrol
as fuel.
Lubrication of chain and chain bar
Whenever you refill the fuel tank with petrol you must also
top up the level of chain oil in the chain oil tank. It is
recommended to use standard chain oil.
Engine pre-start checks
Warning: Never start or operate the saw unless the bar and
chain are properly installed.
1 Fill the fuel tank (A) with correct fuel mixture (Fig. 15).
2 Fill the oil tank (B) with chain oil (Fig. 15).
3 Be certain the chain brake is disengaged (C) before
starting unit (Fig. 15).
Once you have filled the chain and oil tank, tighten the tank
cover securely by hand. Do not use any tools to do so.

Felling is the term for cutting down a tree. Small trees up to
6-7 inches (15-18cm) in diameter are usually cut in a single
cut. Larger trees require notch cuts. Notch cuts determine the
direction the tree will fall.
Warning: A retreat path (A) should be planned and cleared as
necessary before cuts are started. The retreat path should
extend back and diagonally to the rear of the expected line of
fall, as illustrated in Fig. 21.
Warning: If felling a tree on sloping ground, the chain 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.
Note: Direction of fall (B) is controlled by the notching cut.
Before any cuts are made, consider the location of larger
branches and natural lean of the tree to determine the way
the tree will fall (Fig. 21).
Warning: Do not cut down a tree during high or changing
winds or if there is a danger to property. Consult a tree
professional. Do not cut down a tree if there is a danger of
striking utility wires; notify the utility company before making
any cuts.

General guidelines for felling trees (Fig. 22)
Normally felling consists of 2 main cutting operations, notching
(C) and making the felling cut (D). Start making the upper
notch cut (C) on the side of the tree facing the felling direction
(E). Be sure you don t make the lower cut too deep into the
trunk. The notch (C) should be deep enough to create a hinge
(F) of sufficient width and strength. The notch should be wide
enough to direct the fall of the tree for as long as possible.
Warning: Never walk in front of a tree that has been notched.
Make the felling cut (D) from the other side of the tree and
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C).
Never saw completely through the trunk. Always leave a
hinge. The hinge guides the tree. If the trunk is completely
cut through, control over the felling direction is lost.
Insert a wedge or felling lever in the cut well before the tree
becomes unstable and starts to move. This will prevent the
guidebar from binding in the felling cut if you have misjudged
the falling direction. Make sure no bystanders have entered
the range of the falling tree before you push it over.
Warning: Before making the final cut, always recheck the area
for bystanders, animals or obstacles.
Felling cut
1 Use wooden or plastic wedges (A) to prevent
binding the bar or chain (B) in the cut. Wedges also
control felling (Fig. 23).
2 When diameter of wood being cut is greater than
the bar length, make 2 cuts as shown (Fig. 24).
Warning: As the felling cut gets close to the hinge, the tree
should begin to fall. When tree begins to fall, remove saw
from cut, stop engine, put chain saw down, and leave area
along retreat path (Fig. 21).
Limbing
Limbing a tree is the process of removing the branches from a
fallen tree. Do not remove supporting limbs (A) until after the
log is bucked (cut) into lengths (Fig. 25). Branches under
tension should be cut from the bottom up to avoid binding the
chain saw.
Warning: Never cut tree limbs while standing on tree trunk.

Bucking
Bucking is cutting a fallen log into lengths. Make sure you have
a good footing and stand uphill of the log when cutting on
sloping ground. If possible, the log should be supported so that
the end to be cut off is not resting on the ground. If the log is
supported at both ends and you must cut in the middle, make
a downward cut halfway through the log and then make the
undercut. This will prevent the log from pinching the bar and
chain. Be careful that the chain does not cut into the ground
when bucking as this causes rapid dulling of the chain. When
bucking on a slope, always stand on the uphill side.
1Log supported along entire length: Cut from top
(overbuck), being careful to avoid cutting into the
ground (Fig. 26).
2Log supported on 1 end: First, cut from bottom
(underbuck) 1/3 diameter of log to avoid splintering.
Second, cut from above (overbuck) to meet first cut
and avoid pinching (Fig. 27).
3
Log supported on both ends: First, overbuck 1/3
diameter of log to avoid splintering. Second, underbuck
to meet first cut and avoid pinching (Fig. 28).
Note: The best way to hold a log while bucking is to use a
sawhorse. When this is not possible, the log should be raised
and supported by the limb stumps
or by using supporting logs. Be sure the log being
cut is securely supported.
Bucking using a sawhorse (Fig. 29)
For personal safety and ease of cutting, the correct position for
vertical bucking is essential (Fig. 29).
A Hold the saw firmly with both hands and keep the
saw to the right of your body while cutting.
B Keep the left arm as straight as possible.
C Keep weight on both feet.
Caution: When working with the saw, always make
sure that the saw chain and chain bar are sufficiently lubricated.

Maintenance
Warning: All maintenance work on the chainsaw apart from the
work described in this manual may only be carried out by
authorized after-sales service personnel.
Chain brake operational test
Test the chain brake periodically to ensure proper function.
Perform a chain brake test prior to initial cutting, following
extensive cutting, and definitely following any Chain brake service.
Test chain brake as follows (Fig. 30) :
1 Place saw on a clear, firm, flat surface.
2 Start engine.
3 Grasp the rear handle (A) with your right hand.
4 With your left hand, hold the front handle (B) [not chain
brake lever (C)] firmly.
5 Squeeze the throttle trigger to 1/3 throttle, then
immediately activate the chain brake lever (C).
Warning: Activate the chain brake slowly and deliberately. Keep
the chain from touching anything; don’t let the saw tip forward.
6 Chain should stop abruptly. When it does, immediately
release the throttle trigger.
Warning: If chain does not stop, turn engine off and take your unit
to the nearest Gardenline Authorized Service Center for service.
7
If chain brake functions properly, turn the engine off and
return the chain brake to the DISENGAGED position.
Air filter
Warning: Never operate saw without the air filter. Dust and dirt
will be drawn into engine and damage it. Keep the air filter clean!
The air filter must be cleaned or replaced after every 20 hours of
service.
Cleaning the air filter (Fig. 31/32)
1 Remove the top cover (A) by undoing the cover
fastening screw (B) on the cover. You can then
remove the cover (Fig. 31).
2 Lift out the air filter (C) (Fig. 32).
3 Clean air filter. Wash filter in clean, warm, soapy
water. Rinse in clear, cool water. Air dry completely.
Note: It is advisable to have a supply of spare filters.
4 Insert the air filter. Fit the cover for the engine/air filter.
Make sure that the cover fits perfectly when you do so.
Tighten the fastening screw for the cover.
Fuel filter
Warning: Never use the saw without a fuel filter. After 100
hours in operation the fuel filter should be cleaned or, in case
of damage, replaced. Be sure to empty the fuel tank before
changing the filter.
1 Remove the fuel tank cap.
2 Bend a piece of soft wire.
3 Reach into fuel tank opening and hook fuel line. Carefully
pull the fuel line toward the opening until you can reach it
with your fingers.
Note: Do not pull hose completely out of tank.
4 Lift filter (A) out of tank (Fig. 33).
5 Pull off the filter with a twist and clean it; if the filter is
damaged, dispose of it.
6 Insert a new filter. Place one end of the filter into the tank
opening. Make sure that the filter is seated in the lower
corner of the tank. If necessary, use a long screwdriver to
move the filter to its correct position, taking care not to
damage in the process.
7 Fill tank with fresh fuel/oil mixture. See Section Fuel and
Lubrication. Install fuel cap.
Spark plug (Fig. 32)
Warning: To ensure that the saw’s engine retains its power, the
spark plug must be clean and have the correct electrode gap
(0.6 mm). The spark plug must be cleaned or replaced after
every 20 hours of service.
1 Set the On/Off switch to Stop (0)”.
2 Remove the top cover (A) by undoing the cover fastening
screw (B) on the cover. You can then remove the cover

Carburetor setting
The carburetor has been set to its perfect adjustment at the
factory. If it requires adjusting, take the saw to your nearest
authorized after-sales service outlet.
Chain bar maintenance
Regular lubrication of the chain bar (guide rail for the chain and
teeth) is essential. The chain bar needs the maintenance
described in the following section in order for the saw to work
at an optimum level of performance.
Caution: The sprocket tip on your new saw has been
pre-lubricated at the factory. Failure to lubricate the guide bar
sprocket tip as explained below will result in poor performance
and seizure, voiding the manufacturer’s warranty.
Tools for lubrication
The Lube Gun is recommended for applying grease to the
guide bar sprocket tip. The Lube Gun is equipped with a needle
nose tip which is necessary for the efficient application of
grease to the sprocket tip.
To lubricate sprocket tip
Lubrication of the sprocket tip is recommended after 10 hours
of use or once a week, which ever occurs first. Always
thoroughly clean guide bar sprocket tip before lubrication.
Note: The saw chain does not have to be removed in order to
lubricate the teeth of the chain bar. Lubrication is possible
during work, with the engine switched off.
Warning: Wear heavy duty work gloves when handling the bar
and chain.
1 Set the On/Off switch to Stop (0)”.
2 Clean the guide bar sprocket tip.
3 Using the Lube Gun (optional), insert needle nose into the
lubrication hole and inject grease until it appears at outside
edge of sprocket tip (Fig .34).
4 Rotate saw chain by hand. Repeat lubrication procedure
until the entire sprocket tip has been greased.
Most guide bar problems can be prevented merely by keeping
the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw with
chain that is TOO TIGHT will contribute to rapid bar wear.
To help minimize bar wear, the following guide bar maintenance
procedures are recommended.
Warning: Always wear protective gloves during maintenance
operations. Do not carry out maintenance when the engine
is hot.
