Starting The Chain Saw
1. Ensure that you have the correct fuel mixture.
2. Make sure the chain brake (the black lever ① in
diagram) is fully pushed forwards into the lock position.
This ensures the chain does not spin freely when
starting. It is very important that you do this to ensure
that you are not injured.
3. Pull out choke lever fully (④ in diagram).
4. Switch on engine switch (⑧ in diagram).
5. Push the primer 2 or 3 times (⑩ in diagram) and see
figure 38.

Starting The Chainsaw Safely
Never start your chain saw using the
drop method where you drop the saw with
one hand while pulling the starting cord with
the other hand.
This is highly dangerous!
1. Lay the chain saw onto the ground and then
position yourself with your right boot in the throttle
handle area (⑪ in diagram) firmly keeping it still.
2. At the same time firmly hold with the left hand onto
the main handle (⑥ in diagram).
3. Pull the pull cord firmly until the engine starts.
Make sure that you never let go of it allowing it to
retract quickly as this will damage the pull cord
mechanism..
4. Slowly return the starter handle to original position.
Never let go and allow it to spring back!!
5. Repeat the above two steps until engine starts.
6. Push in the choke lever (④ in diagram).
7. Once the engine has started, release the button on
the throttle interlock (⑦ in diagram) to put the
engine into an idling mode.
Trueshopping

Page: 44 of 77
Note: Sometimes you have to leave the choke on until the
engine warms up, mastering the position of the choke lever is
an art on all our petrol tools and you get used to the sound of
the engine with more usage of the saw. When the throttle is
first applied the “half throttle” button will return to its normal
position.

Operating The Machine
It is recommended to first practice sawing easy logs. This also
helps you get accustomed to your unit.
Removal of the safety devices, inadequate maintenance, or
incorrect replacement of the bar or chain may increase the
risk of serious personal injury.
The chain saw must only be used for cutting
wood. It is forbidden to cut other types of
material.
Do not use the chain saw as a lever for lifting,
moving or splitting objects.
Do not add any attachments to the chain saw
that are not specified in this manual.
Do not lock it over a fixed stand.
Trueshopping
www.TrueShopping.co.uk
Page: 47 of 77
It is extremely important that the chain brake is
checked for proper operation before each use
and that the chain is sharp in order to maintain
the kickback safety level of this saw.
Never start cutting until you have a clear work
area, secure footing and a planned retreat path
from the falling tree. Check working place, the
cutting object and cutting direction. If there is
obstacle, remove it.
Use caution and keep bystanders and animals
out of the working area whose diameter is 2.5
times the cutting object.
Always hold the machine firmly with both
hands when the engine is running.
Keep all parts of your body away from the
machine when the engine is running.
Trueshopping
www.TrueShopping.co.uk
Page: 48 of 77
Cut at the correct engine speeds for the size
and position of the sapling, branch or tree. Do
not overreach or cut above shoulder height.
It is not necessary to force the saw into to the
cut, Apply only light pressure while running the
engine at full throttle.
When the saw chain is caught in the cut do not
attempt to pull it out by force but use a wedge
or a lever to open the cut.
Never touch the exhaust, spark plug or other
metallic parts of the engine while the engine is
in operation or immediately after stopping the
engine. Doing so could result in serious burns
or electrical shock.
Do not rely exclusively on the safety devices
built into your saw.
Always shut off the engine before putting it
down.
Trueshopping
www.TrueShopping.co.uk
Page: 49 of 77
Use extreme caution when cutting small size
brush and saplings because slender material
may catch the saw chain and be whipped
towards you or pull you off balance.
When cutting a limb that is under tension, be
alert for spring back so that you will not be
struck when the tension in the wood fibbers is released.
Check the tree for dead branches that could fall during the
felling operation.
When operating the chain saw:
Always cut to the outside of your
legs. Never make a cut by sawing between
your legs.
Do not stand on any unsafe ground
such as another log when using the saw.
Never straddle or stand on a limb that you are cutting.
Always keep in mind where the chain will go if it comes
off.
Always keep the chain free of debris.
Never cut into debris as there may be hidden perils or
small animals.
Trueshopping
www.TrueShopping.co.uk
Page: 50 of 77
Someone should be with you in case of an
accident when you are using the chain saw,
particularly if you are in a remote area. Have
the telephone number and address of the
nearest emergency unit, and always carry a
first-aid kit when you work in the woods. If
someone is injured, cover the wound with a clean cloth and
press hard to stop the flow of blood. Get the injured person to
a doctor or hospital immediately.
Trueshopping

Page: 51 of 77
Kickback Safety Precautions
Be aware that the chain saw may kickback if it
gets stuck in the limb or branch you are
cutting. See the next section for more
information.
With a basic understanding of kickback you can reduce or
eliminate the element of surprise. Sudden surprise contributes
to accidents.
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 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 lose control of the saw
which could result in serious personal injury.
Trueshopping
www.TrueShopping.co.uk
Page: 52 of 77
Keep a good 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.
Make certain that the area in which you are cutting is free
from obstructions. Do not let the nose of the guide bar
contact a branch, or any other obstruction which could be hit
while you are operating the saw.
Trueshopping
www.TrueShopping.co.uk
Page: 53 of 77
Chain Saw Operation
When using a chain saw to cut firewood, trim trees or harvest
large timber, you need to perform three basic operations:
felling, limbing and bucking.
Felling involves cutting a standing tree and dropping it in the
place you want it.
Limbing is the removal of the branches from either standing
or downed trees.
Bucking is the process of cutting a downed tree into
appropriate lengths.
The Saw Spike: When you place your running saw blade down
on the wood you rock the blade upward and then lever it
down into the wood. The saw spike grips into the wood and
gives you a leverage spike, otherwise you would have to keep
trying to push down on the blade, which does work, but the
teeth really assist in that levering, hence speeding the cutting
motion and saving a lot of work.

Felling A Tree
Felling a tree can cause problems sometimes. You always
want to ensure that you know exactly where the tree is going
to land. Here is the 3 step plan.
1) Examine the Tree and Surroundings
Look for any rot in the tree, where the
branches are placed and how tall the tree is.
Unless you are very experienced, do not
touch a rotting tree as they may snap or
break in a haphazard fashion.
Look around you for items especially people
and power lines that may interfere with the
tree or be in the area where you expect the
tree to be. For example: if the tree is
approximately 3m high then ensure that
nothing is in the way of a circle at least 4m from the tree.
Ensure that there are no branches that are liable to fall onto
you and cause serious injury. Branches often get dislodged
during the felling process.

Ensure that there are no other trees in the area that you
expect your tree to fall. This may cause the felled tree to
become lodged in the other tree, or worse still, bounce off the
tree and cause injury or damage.
2) Plan at Least Two Escape Routes
The first escape route should be opposite
the planned direction of the tree fall and the
other at approx 45° from the first route.
Ensure that both these escape routes are
clear of all people and obstacles and do not
put your tools in these areas. Ensure that
you have a safe place to drop your chain saw in an emergency
as you should NEVER RUN holding a chain saw.

3) Make the Cuts
Clear the area around the base of the tree from all brush, tree
limbs and other obstructions.
If the tree is less than ¼m then make the cut through the
trunk. If the tree is larger then make two cuts – the undercut
and the back cut.
Figure 46 Making the Cuts
Trueshopping

Page: 57 of 77
1,2 Undercut: is a V shaped notch on the side of the tree on the
side that is in the direction of felling. The first cut (2) of the V is
made parallel to the ground and then the other slanting cut (1)
is made. Some people use a 45° cut and some use a 90° cut.
Usually the undercut is to a depth of ¼ of the diameter of the
tree.
3, 4 Backcut: is made on the opposite side of the tree, slightly
above the hinge spike of the V shaped undercut. This
releases the stresses on the tree allowing the tree to fall.
NEVER make the backcut lower than the undercut as you will
lose control of the tree. As you are nearing the undercut
leave a small hinge of wood (4) in order to hold the tree and
act as a pivot as the tree falls.

The angled hinge means that the tree will start to fall on the
narrow section of the hinge while the wood at the thicker
section of the hinge is still intact. The tree is therefore pulled
toward the thick section. Making these cuts is an art and
requires practice.
Once the tree starts to fall, turn off the saw and take your
chosen escape path so that you are away from the falling tree.
Beware: Falling trees have been known to
bounce backward over the stump and injure
an unwary operator.

Limbing a Tree
Never limb a tree when the limb is above shoulder height as
this may cause you to lose control of the chain saw.
Examine the Tree
Evaluate a fallen tree to ensure that it is not
lodged in another tree and not fallen
completely to the ground. These are
potentially dangerous and best left to a
professional.
Check for the following danger signals:
Are smaller trees trapped by the tree to be limbed?
Is the tree to be limbed totally and safely laying on the
floor?
Is the tree to be limbed on level ground?
Is there debris on the tree to be limbed that may fall on
you during the procedure?
Once you have removed all obstacles and
potentially dangerous debris then stand
uphill to the tree to be limbed. If you stand
downhill and free a limb this may then allow
the rest of the tree to roll onto you.

Cutting the Limbs
Stand firmly on the ground in a balanced
position that gives you freedom of
movement. Ensure that you will not slip.
Start at the bottom of the tree and work
your way to the top, removing branches on
the opposite of the tree. ALWAYS cut away
from you. Beware of kickback which
happens when your blade gets caught in the
wood being sawn.
Remove the debris and cut
limbs as you go, placing
them in a safe position that
does not impede your work.
Cutting the limbs off close
to the tree trunk makes the
resulting trunk easy to roll at
the end of your limbing.
Beware of the tree trunk
moving as you remove
heavier limbs.

Bucking a Tree
This is the process of cutting a tree into
usable lengths and can be done as you are
limbing the tree.
If the tree is laying on the ground, ensure that
you do not get your saw blade caught in the
earth or on any other debris that may be present.
Stand uphill of the tree and make
sure you have a strong, firm even
stance on the ground. Be ready to
move quickly if the log rolls while
you are cutting.
A sawbuck or sawhorse makes
cutting a lot easier and safer.

Maintenance
Always be sure to turn off the engine before
performing any maintenance or checking
procedures.
Leave all maintenance other than mentioned
in this manual to your servicing dealer.
The metallic parts reach high temperatures
immediately after stopping the engine.
Only use replacement bars and chains
specified by the manufacturer or the
equivalent.
Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Always carry the unit with the engine
stopped, the guide bar covered with the
protector to the rear, and exhaust away from
your body.

Chain Oil
Use motor oil SAE#10W-30 all year round or
SAE #30-#40 in summer and SAE #20 in
winter. Do not use wasted or regenerated oil
that can cause damage to the oil pump.
Changing Oil Supply
Be sure to refill the oil tank every time when refuelling the
unit.
The chain oil flow can be changed by inserting a screwdriver in
the hole on the bottom of the clutch side. Adjust according to
your work conditions. See page 29, fig 25, for details and
image.
Your Warranty
Warranty claims should be made according to the warranty
certificate enclosed in the packaging.

Adjusting Carburettor
The carburettor on your unit has been factory
adjusted but may require fine turning due to
change in operating conditions.
Before adjusting the carburettor, make sure
that provided are clean air/fuel filters and fresh, properly
mixed fuel.
When adjusting, take the following steps:
Be sure to adjust the carburettor with the bar chain
attached and the unit turned off.
Stop engine and screw in both H and L needles until
they stop. Never force. Then set them back the initial
number of turns shown below.
o H needle: 1±3/8
o L needle: 1

Carburettor Antifreeze Mode
Operating the chain saw in temperatures of
0-5°at times of high humidity may result in ice
forming within the carburettor, and this in
turn may cause the output power of the
engine to be reduced or for the engine to fail
to operate smoothly.
This product has accordingly been designed with a ventilation
hatch the back of the air cleaner cover to allow warm air to be
supplied to the engine to prevent icing from occurring.
Under normal circumstance the product should be used in
normal operating mode, i.e., in the mode to which it is set at
the time of shipment however when the possibility exists that
icing may occur. The unit should be set to operate in
anti-freeze mode before use.
How To Switch To Anti Freeze Mode
Flip the engine switch to turn off the engine.
Remove the air cleaner cover from the cylinder cover.
Reattach the screen right side left so as to the anti-icing
plate is on the right.
Reinstall the cover.
Continuing to use the product in anti-freeze

mode when temperature has risen and returned to normal
may result in the engine failing to start properly or in the
engine failing to operate at its normal speed. For this reason
you should ALWAYS be sure to return the unit to normal
operating mode if there is NO danger of icing occurring.
Air filter
Clean the air filter on a regular basis and change as necessary.
Sprocket
Check for cracks and for excessive wear that may be
interfering with the chain drive. If the wear is found then
replace it with new one. Never fit a new chain on a worn
sprocket, or a worn chain on a new sprocket.

Saw Chain
It is very important for smooth and safe
operation to keep the cutters sharp. Always
wear gloves when doing this. Your cutters
need to be sharpened when:
Sawdust becomes powder-like.
You need extra force to saw in.
The cut way does not go straight.
Vibration increases.
Fuel consumption increases.
Always contact an experienced company to
maintain and repair your chain saw.
