Safe Handling of Fuel
The engine of the Chainsaw is designed to run on a two stroke oil/fuel mixture.
This fuel is highly flammable; never store cans of fuel or refill the fuel tank in any place where
there is a source of heat or fire, which might ignite the fuel.
Do not smoke whilst operating or reflling the Chainsaw, keep lit cigarettes away from the
Chainsaw at all times.
When refilling the fuel tank always stop the engine first and carefully make sure that there are no
sparks or naked flames anywhere nearby before refuelling.
If any fuel spillage occurs during refuelling, use a dry rag to wipe any fuel which has been spilled
onto the Chainsaw before starting the engine.
After refuelling, screw the fuel cap back tightly onto the fuel tank and carry the Chainsaw to a
spot 5 metres or more away from where it was refuelled before starting the engine.
Two-Stroke Fuel
Fuel is very flammable. Do not smoke or bring any flame or sparks near fuel.
The engine is lubricated by oil mixed into petrol. Prepare a mixture of unleaded petrol and semi-
synthetic two-stroke oil that meets the specifications of: API TC, ISO-L-EGC, JASO FC (Low Smoke)
oil.
Recommended mixing ratio is 40:1.
Page 12
CS260TX PREMIUM Chainsaw
12
Original Instructions Version November 16
CS260TX_141116
FUEL WITH NO OIL (RAW PETROL) will cause severe damage to the engine which is not covered by the manufacturer’s warranty.
Use fresh, unleaded petrol (95 RON) and semi-synthetic oil specially made for high performance
two-stroke engines. Mix in a ratio of 40 parts petrol to 1 part of oil.
By using two-stroke oil specially made for two-stroke engines you will reduce the formation of ash
and carbon deposits on the spark plug, piston, exhaust muer and cylinder as well as reducing
emissions of harmful exhaust gases.
Oil FOR 4-CYCLE ENGINES should not be used as two-stroke lubrication oil as it can cause fouling
of the spark plug, exhaust port blocking, piston ring sticking and other internal engine damage.
NOTE
Due to increased Ethanol content in petrol we recommend the use
of B3C Ethanol Shield 2-Stroke Oil, or Ethanol Shield Fuel Stabiliser
to protect your MITOX® engine against the harmful eects of
Ethanol.
Visit www.b3cfuel.co.uk for more information.
IMPORTANT
!
Fuel Storage (Without Ethanol Shield)
Mixed two-stroke fuel which has been left unused for a period of one month or more may
damage the carburettor and result in the engine failing to start or operate correctly.
Page 13
CS260TX PREMIUM Chainsaw
13
Original Instructions Version November 16
CS260TX_141116
When storing the Chainsaw for a period of more than one month, empty the fuel tank and
run the engine to empty the carburettor of fuel.
Two-stroke fuel can cause deterioration of rubber and/or plastic components during prolonged
storage.
It is important to only use good quality, fresh fuel.
Fuelling
Shake the fuel container to thoroughly mix the two-stroke oil and petrol.
Clean dirt from around the fuel cap before removing.
Pour two-stroke fuel into the fuel tank with a filtered funnel, up to 80% of the fuel tank’s capacity.
Replace the fuel cap and tighten securely. Spilled fuel must be wiped away from the Chainsaw
before starting the engine.
Move at least 5m away from the refuelling area before restarting the engine.
When refilling the tank, always turn o the engine and allow it to cool down. Take a careful look
around to make sure that there are no sparks or open flames anywhere nearby before refuelling.
Chain Oil
Use only specialist anti fling chain oil. Fill the chain oil tank every time you fill the fuel tank.
Do not use waste or regenerated oil that can cause damage to the oil pump.

8. Adjust the position of the tensioner nail (3) on the chain cover and insert into the lower
hole of the guide bar. Fasten the chain cover nut (fig 1.1) finger tight and while holding
up the tip of the bar, adjust the chain tension by turning the tensioner screw (4) until the
chain does not sag from the underside of the guide bar (Figure 5).
9. Tighten the bar nuts securely with the bar held up to 12/15N.M, then check the chain for
smooth rotation and proper tension while moving the chain by hand (Figure 6).
Figure 5. Figure 6.
A new chain will expand in length at the beginning of use. Check and readjust the tension frequently,
as a loose chain can easily derail or cause rapid wear to itself and the guide bar.
NOTE
10. Check the tension of the saw chain - Use
your gloved hand to lift the chain link positioned in
the centre of the guide bar, using approx 10N force.
If the chain link can be moved outside of the rail of
the guide bar, the chain requires further tightening
(Figure 7).

Chain Brake
This machine is equipped with an automatic brake to stop the saw chain rotation upon the
occurrence of kickback during saw cutting. The brake is automatically operated by inertial force,
which acts on the weight fitted inside the front guard.
The brake can also be operated manually by pushing the chain brake forward towards the guide
bar. To release the brake, pull back the chain brake (4) toward the rear handle (1) until a “click”
sound is heard (2).
How to check:
You must check the chain brake operation before each usage by running the saw at full throttle
for 1-2 seconds and pushing the front hand guard (4) forward (3).
The chain should stop immediately with the engine at full speed.
If the chain is slow to stop or does not stop, replace the brake band and clutch drum before use.
Always follow the safety regulations:
The chainsaw must only be used for cutting wood. It is forbidden to cut other types of material.
Vibrations and kick-back vary with dierent materials and the requirements of the safety
regulations would not be met. Do not use the chainsaw as a lever for lifting, moving or splitting
objects. The saw should cut easily without force. 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 suciently open the gap in the wood.

CS260TX_141116
Kickback Safety Precautions
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. Top 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.
Do not rely exclusively on the safety devices built into your saw. As a chain saw user you should
take several steps to keep 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 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 chainsaw handles. A firm grip will help you reduce
kickback and maintain control of the saw.
3. 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 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 the manufacturer's sharpening and maintenance instructions for saw chain.
7. Only use replacement bars and chains specified by the manufacturer.
It is important to maintain the proper chain tension. Rapid wear of the guide bar or the chain coming o can be caused by improper tension, especially when using a new chain.

Adjusting Oil Flow Rate
Never fill the oil reservoir or adjust the oiler with the engine running.
An increase in bar oil flow rate will speed oil consumption, requiring more frequent checks on the oil
reservoir. To ensure sucient lubrication, it may be necessary to check the oil level more frequently
than at fuel tank refills. The guide bar and chain are lubricated automatically by a pump that
operates whenever the chain rotates. The pump is set at the factory to deliver a minimum flow rate,
but it can be adjusted in the field. A temporary increase in oil flow is often desirable when cutting
hardwood.
Adjust the pump as follows:
1. Stop the engine and make sure the stop switch is in the OFF position.
2. Place the unit on its side with the sprocket side and chain brake assembly facing up.
3. With a screwdriver, push in on the oil flow rate adjusting screw and turn in the desired
direction: Clockwise-decrease lubrication / Counter clockwise-increase lubrication.

Saw Chain Sharpening
The chain needs to be sharpened when:
1. Sawdust becomes powder-like. 4. You need extra force to saw with.
2. The cut path does not go straight. 5. Vibration increases.
3. Fuel consumption increases.
Be sure to wear safety gloves.
• Clamp chain saw guide bar in a vice to secure.
• Sharpen chain with a 5/32 (4mm) file and holder (Oregon part number 16265) / Sharpening kit
(Oregon part no 90405)
• Place your file on the cutter and push straight forward. Keep the file position.
• After every cutter has been set, check the depth gauge and file it to the proper level.

Adjusting the Carburettor
The carburettor has been factory adjusted, but may require fine tuning due to a change in operating
conditions. Before adjusting the carburettor, make sure that the provided air/fuel filters are clean
and the fuel properly mixed.
When adjusting, take the following steps:
Stop the engine and screw in both the H and L needles until they stop. Never force them. Then set
them back the initial number of turns as shown below.
H needle: 2 + or -¼ L needle: 2 + or -¼
1. Start the engine and allow it to warm up at half-throttle.
2. Turn the L needle (2) slowly to find a position where
idling speed is at maximum, then set the needle back
a quarter (1/4) turn counter clockwise.
3. Turn the idle adjusting screw T (1) counter clockwise so
that the saw chain does not turn. If the idling speed is
too slow, turn the screw clockwise.
4. To verify the low speed you should be able to pull the
throttle in all the way and the engine should not die,
if it tries to die, open the L jet (2) slightly and re-adjust
idle if necessary.
5. Set the engine to full throttle, the H jet (3) is turned clockwise to reduce fuel, as the fuel
mixture is leaned out, the saw will run faster until it sounds as if it is screaming, at this point, turn
the high speed screw counter clockwise by quarter (1/4) turn to allow more fuel in.
A 2-cycle engine relies on the fuel mixture to cool the engine; a lean engine will run fast but can
overheat and may cause severe damage to the engine.It is recommended carburettor adjustments
are carried out by authorised Mitox dealers only.

Working with tree service chain-saws from rope and harness
1. Overview
This chapter sets out working practices aimed at reducing the risk of injury from tree service chain-
saws when working at height from a rope and harness. While it may form the basis of guidance
and training literature, it should not be regarded as a substitute for formal training. The guidance
given in this annex is only an example of best working practice. National laws and regulations
should always be followed.
It presents
- General requirements that should be met before using a tree service chain-saw for work at height
from a rope and harness,
- Preparations for using a tree service chain-saw from a rope and harness, and
- Use of a tree service chain-saw for pruning and dismantling, including secure work positioning for
two-handed use, starting the chain-saw, cutting with the chain-saw, restrictions on one-handed use
and freeing a trapped saw.
2. General requirements
Operators of tree service chain-saws working at height from a rope and harness should never work
alone. A ground worker trained in appropriate emergency procedures should assist them.
Operators of tree service chain-saws for this work should be trained in general safe climbing and
work positioning techniques and be properly equipped with harnesses, ropes, strops, carabiners
and other equipment for maintaining secure and safe working positions for both themselves and
the saw.
3. Preparing to use the saw in the tree
The chain-saw should be checked, fuelled, started and warmed up by the ground worker and then
switched o before it is sent up to the operator in the tree.
The chain-saw should be fitted with a suitable strop for attachment to the operator’s harness (see
Figure B.1):
a) Secure the strop around the attachment point on the rear of the saw;
b) Provide suitable carabiners to allow indirect (i.e. via the strop) and direct attachment (i.e. at the
attachment point on the saw) of the saw to the operator’s harness;
c) Ensure the saw is securely attached when it is being sent up to the operator;
d) Ensure the saw is secured to the harness before it is disconnected from the means of ascent.

Figure B.1 — Example of attachment of tree service chain-saw to operator’s harness
The ability to directly attach the saw to the harness reduces the risk of
damage to equipment when moving around the tree. Always switch
the saw off when it is directly attached to the harness.
The saw should only be attached to the recommended attachment
points on the harness. These may be at mid-point (front or rear) or at
the sides. Where possible, attach the saw to the centre rear mid-point
to keep it clear of climbing lines and to support its weight centrally
down the operator’s spine. See Figure B.2.
When moving the saw from any one attachment point to another,
operators should ensure it is secured in the new position before
releasing it from the previous attachment point.
Figure B.2 — Example of attachment of tree service chain­saw to centre rear mid-point on harness
4. Using the chain-saw in the tree
An analysis of accidents with these saws during tree service operations
shows the primary cause as being inappropriate one-handed use of
the saw. In the vast majority of accidents, operators fail to adopt a
secure work position that allows them to hold both handles of the
saw. This results in an increased risk of injury due to
- Not having a firm grip on the saw if it kicks back,
- A lack of control of the saw, such that it is more likely to come into contact with climbing
lines and the operator’s body (particularly the left hand and arm), and
- Loss of control owing to an insecure work position and resulting in contact with the saw
(unexpected movement during operation of the saw).

Securing the work position for two-handed use
In order to allow the saw to be held with both hands, as a
general rule operators should aim for a secure work position
in which they operate the saw at
- Hip level, when cutting horizontal sections, and
- Solar plexus level, when cutting vertical sections.
Where the operator is working close into vertical stems
with low lateral forces on the work position, then a good
footing could be all that is needed to maintain a secure
work position. However, as operators move away from the
stem, they will need to take steps to remove or counteract
the increasing lateral forces by, for example, a redirect of
the main line via a supplementary anchor point or use of an
adjustable strop direct from the harness to a supplementary
anchor point (see Figure B.3).
Figure B.3 — Example of redirection of main line via supplementary anchor point
Gaining a good footing at the working position can be assisted by the use of a temporary foot
stirrup created from an endless sling (see Figure B.4).
Figure B.4 — Example of temporary foot stirrup created from endless sling
Starting the saw in the tree
When starting the saw in the tree, the operator should
a) apply the chain brake before starting,
b) hold the saw on either the left or right of the body when starting,
1) on the left side, hold the saw with the left hand on the front
handle and thrust the saw away from the body while holding the
pull starter cord in the right hand, or
2) on the right side, hold the saw with the right hand on either
handle and thrust the saw away from the body while holding the
pull starter cord in the left hand.
The chain brake should always be engaged before lowering a running saw onto its strop.
Operators should always check that the saw has sucient fuel before undertaking critical cuts.

One-handed use of the chain-saw
Operators should not use tree service chain-
saws one-handed when the work position is
unstable or in preference to a handsaw when
cutting small diameter wood at the branch
tips.
Tree service chain-saws should only be used
one-handed where
- operators cannot gain a work position
enabling two-handed use, and
- they need to support their working position
with one hand, and
- the saw is being used at full stretch, at right
angles to and out of line with the operator’s
body (see Figure B.5).
Figure B.5 — Example of one-handed chain-saw use
Operators should never
- cut with the kickback zone at the tip of the chain-saw guide bar,
- “hold and cut” sections, or
- attempt to catch falling sections.
Freeing a trapped saw
It the saw becomes trapped during cutting, operators should
- switch off the saw and attach it securely to the tree inboard (i.e. towards the trunk side)
of the cut or to a separate tool line,
- pull the saw from the kerf whilst lifting the branch as necessary,
- if necessary, use a handsaw or second chain saw to release the trapped saw by cutting a
minimum of 30 cm away from the trapped saw.
Whether a handsaw or a chain-saw is used to free a trapped saw, the release cuts should always
be outboard (toward the tips of the branch), in order to prevent the saw being taken with the
section and further complicating the situation.
