C) Instructions on the safe use of the chain saw
ATTENTION: Read the operating instructions carefully and
familiarise yourself in the correct use of the chain saw be-
fore using it for the rst time.
●Before storage allow the engine to cool. When not in use,
store the chain saw in a dry and locked place, out of reach
of children.
● Use only genuine Ratnagiriimpex replacement parts
when servicing or repairing the unit. These parts are avail-
able from your supplying dealer or service agent.
● Repairs may only be performed by authorized service
agents.
● Avoid dangerous environments. Do not use the unit in
poor light or in damp or wet locations. Do not use in the
rain. Do not over-reach. Ensure good footing and balance is
maintained.
● Inspect your petrol chain saw before each operation. Pay
special attention to the chain-bar and chain. If any part is
damaged or worn, repair or replace before operation.
●Always hold the chain saw rmly with both hands while
working with it.
● No other person may be within the working range of the
chain saw.
●When not in use put the chain saw down in such a
manner that there is no risk of injury.
●Switch the device o, wait for the chain to come to a
complete standstill and disconnect the spark plug before
setting, servicing, cleaning, transportation or storage.
●Always use the chain cover when transporting the chain
saw.
●Hold the chain saw rmly when starting. The chain and
bar must be free.
● Before starting work ensure that you are standing rmly.
● Never cut with the tip of the bar – the chain saw may
recoil (“kick-back”)
● Do not use the chain saw near combustible gases or dust
– danger of explosion.
● Always ensure all handles and guards are tted when us-
ing the chain saw. Ensure all screws and nuts are properly
tightened before use.
●Only operate this chain saw once correctly and fully as-
sembled.
●Switch the chain saw o immediately if you notice any
changes in the machine.
● Always have a rst-aid kit at hand in case of accidents.
● If the chain comes into contact with soil, stones, nails or
other foreign objects,stop the chain saw immediately and
check the chain as well as the bar.
●Never leave the chain saw unsupervised.
● Ensure that no chain oil penetrates into the soil or sew-
age. Always place the chain saw on something that will
absorb any oil dripping from the bar or chain.
● Stop the engine and disconnect the spark plug if the
chain saw becomes blocked.
● Never remove any of its components and never use a dam-
aged or incomplete machine. Never modify any of the machine
components.
● Do not use your petrol chain saw for any jobs other than
those for which it was intended.
●WARNING: Petrol and its vapours are highly ammable.
Always stop the engine before refueling. Do not smoke or light
any ames while refueling. Wipe o any fuel that may have
spilled. Refuel in a well ventilated area and never in closed en-
vironments. Start the engine away from the place where it was
refueled. Ensure the tank cap is tightened properly. Return the
chain saw to its normal operating position before starting.
● CAUTION: Exhaust fumes are toxic and asphyxiating. Inha-
lation may be lethal. Do not start the engine in closed or poorly
ventilated environments.
● If the chain becomes jammed or blocked by obstacles,
switch the engine o immediately and visually inspect the
chain saw for damage. Note, if the chain saw is damaged,
repairs and servicing must only be performed by authorised
dealers and service agents.
D) Warning: Danger of recoil (“kickback”)
WARNING: While the engine is running, 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 opera-
tor. 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 the operator to lose control of the
saw which could result in the chain saw being ung upwards
at high speed towards the person holding the chain saw and
causing 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:
● With a basic understanding of kickback you can reduce or
eliminate the element of surprise. Sudden surprise contrib-
utes to accidents.
● 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 rm grip with
thumbs and ngers encircling the chain saw handles. A rm
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 log, branch, or any other obstruction which could
be hit while you are operating the saw.
● Do not overreach or cut above shoulder height.
● Follow manufacturers sharpening and maintenance in-
structions for saw chain.
● Only use replacement bars and chains specied by the
manufacturer or the equivalent.
● If possible, use a log stand for cutting loose logs.
● Always keep aware of the bar tip relative to other objects.
● Cut at high engine speeds. Never start the machine while
the chain rests on an object.
● Piercing cuts with the bar tip may only be performed by
trained and experienced operators.
E) Instructions on safe working techniques
● Always maintain a normal body posture when operating
the device. Always keep your balance.
● Do not work with your body bent forwards.
● Do not work on ladders, scaolding, walls or trees.
● Do not use the chain saw above shoulder height.

ASSEMBLY OF CHAIN SAW
CAUTION: The saw chain has very sharp edges. Always
use safety gloves
when assembling the chain.
Your chain saw package contains the following items as
illustrated in gure 1.
Assemble the guide bar and the saw chain on the pow-
er unit as follows:
1. Ensure the spark plug wire is disconnected and keep it
away from spark plug.
2. Place the chain saw on a stable surface.
3. Pull the guard towards the front handle to check that the
chain brake is not
on (Fig.2).
4. Loosen the nuts (Fig.3a) and remove the chain cover
(Fig.3b).
5. Install the included claw to the power unit (Fig.4) if it is
not pre-tted.
6. Gear the chain to the sprocket (Fig.5) and, while tting
the saw chain around the guide bar, mount the guide bar to
the power unit (Fig.6).
NOTE:
Pay attention to the correct direction of the saw chain. The
cutting teeth on the upper side of the bar must point in the
forward direction (Fig.7)
7. Adjust the position of chain tensioner screw on the chain
cover to the lower hole of guide bar (Fig.3b) If necessary,
adjust the tensioner screw until the tensioner bolt is seated
in the lower hole in the bar.
8. Fit the chain cover to the power unit and fasten the nuts
(Fig.3a) to nger tightness.
9. Check that all chain links are seated correctly in the
bar’s groove and that the chain is tted around the driving
sprocket correctly.
10. While holding up the chain bar, adjust the chain ten-
sion by turning the tensioner screw until the chain links
just touch the bottom side of the bar rail (Fig.8). The chain
should be tensioned such that it can be lifted about 3 mm in
the middle of the bar (Fig.8).
11. Tighten the chain cover nuts securely (12-15N.m).
Check the chain for smooth rotation and proper tension
while moving it by hand.
12. If necessary, readjust the tension of the chain by rst
loosening the chain cover nuts slightly, then again adjusting
the chain tension by turning the tensioner screw. Securely
retighten the chain cover nuts.
NOTE:
A new chain will expand its length in the beginning of use.
Check and readjust the tension frequently as a loose chain
can easily derail or cause rapid wear of itself and the guide
bar.
The chain tension has a signicant eect on the life of the
chain saw, and must therefore be checked regularly. When
the chain warms up to operating temperature it will expand
a little and might need to be re-tensioned.
FUELLING
1. This product is equipped with a 2-stroke engine which
requires 2-stroke lubricating oil to be pre-mixed with petrol.
Mix both thoroughly (as per fuel-mix ratio) in a separate
container. Always prepare the fuel-mixture and refuel the
chainsaw outside in a well ventilated environment.
2. Use Lawn Star high performance 2-stroke oil (stock code
90-20000) and lead-free petrol (Octane 95).
3. Oil/Fuel mix ratio for normal 2-stroke engine oil - 1:25
(4%) e.g. 40 ml of oil per 1 litre of petrol
4. Always stop the engine before refueling. Do not smoke or
light any ames while refueling.
5. Wipe o any fuel that may have spilled. Start the engine
away from the place where it was refueled. Ensure the tank
cap is tightened properly. Return chainsaw to its normal
operating position before starting.
CHAIN OIL
The chain saw must never be operated without chain oil
as this will cause damage to the chain, bar, and engine. No
claims under warranty can be accepted if damage occurs
due to the chain saw being operated without chain oil.
Use Lawn Star chain lube (stock code 90-30000). Alterna-
tively motor oil grade SAE 10W-30 can be used.
NOTE: Do not use waste or recycled oil that can cause
damage to the oil pump.
Fill approximately 260ml oil into the tank using a funnel
and replace the cap securely.
Remove the chain oil from the oil tank if the chain saw is
not used for a long period.
The oil tank should be emptied before the chain saw is
transported.
After use, lay the chain saw horizontally on an absorbent
surface.
BEFORE USING THE CHAINSAW
Before proceeding to your job, read “IMPORTANT IN-
STRUCTIONS FOR YOUR PERSONAL SAFETY” section.
Always follow the safety procedures and guidelines.
Check chain saw for damage before starting work.
Ensure that the chain tension is correct. If the chain is too
loose, it may come o during use and lead to injuries. The
chain must be replaced immediately if it is damaged. The
cutting teeth must be at least 4 mm long.
Check the sharpness of the chain every time before using
the chain saw. Sharpening a chain requires experience and
specialised knowledge, therefore it is recommended that
sharpening be carried out by a specialised workshop, or a
new chain be used.
It is recommended to rst practice sawing on smaller eas-
ier-to-cut logs.
This helps to get accustomed to the chainsaw.
SAFETY DEVICES ON THE CHAIN SAW
CHAIN BRAKE
This machine is equipped with a mechanical chain brake.
In the event of kickback, the chain brake guard (Fig.10-
No.1) will be activated by the back of the operators hand
and saw chain rotation will be stopped. The engine will con-
tinue to run until switched o.
Immediately release the throttle lever as soon as the
chain brake is activated.
Switch the engine o as soon as possible if the chain
brake is engaged to prevent the clutch from overheating.
The brake will only be activated if operating the chain saw
correctly.
Always insure that the chain brake guard is locked into
the operating position (Fig.2) before starting the chain saw.
CAUTION: The engine must be switched o before the
chain brake is released.
To release brake, pull up the front guard toward the front
handle till “click” sound is heard.
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 forward. The chain should stop imme-
diately with the engine at full speed. If the chain is slow to
stop or does not stop, have the brake band and clutch drum
replaced or serviced before using the chain saw.
It is extremely important that the chain brake be checked
for proper operation before each use and that the chain is
sharp. Removal of the safety devices, inadequate main-
tenance, or incorrect replacement of the bar or chain may
increase the risk of serious personal injury due to kickback.
CHAIN CATCH BOLT
The chain saw is tted with a chain catch bolt (Fig.4).
Should the chain break when the saw is in use, the chain
bolt will catch the loose chain end and thus prevent injury to
the operator’s hand.
Take regular breaks.
After use always place the chain saw horizontally to avoid
oil dripping from the chain oil reservoir.
Always use the chain cover when transporting the chain
saw.
Prevent the chain from contacting soil.
