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 specied 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, sca󰀨olding, 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 signicant e󰀨ect 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.

 After starting the engine, run the chain at medium speed
and observe if chain oil is sprayed o󰀨 (Fig.12).
 First switch o󰀨 the engine, wait for the chain to stop and
then remove the spark plug wire before adjusting the chain
oil ow.
 The chain oil ow-rate can be changed by adjusting the
screw in the hole on bottom of the clutch side (Fig.13). Ad-
just according to your work conditions.
NOTE
The oil tank should become nearly empty by the time fuel is
used up. Be sure to rell the oil tank every time when refuel-
ing the unit.
ADJUSTING CARBURETOR (REFER TO FIGURE 14)
 The carburetor on the chain saw has been factory adjust-
ed, but may require ne turning due to change in operating
conditions.
 Before adjusting the carburetor, make sure you have
clean air/fuel lters and fresh, properly mixed fuel.
 Note: Be sure to adjust the carburetor with the bar chain
attached
 When adjusting, take the following steps:

INSTRUCTIONS ON THE CORRECT USE OF THE CHAIN
SAW
REMOVING BRANCHES (Fig.15)
 Ensure that you are standing properly.
 Cut a deep notch from below into the branch about 15cm
from the trunk.
 Now cut the branch from above about 5cm further out-
wards from the lower notch until the branch drops o󰀨.
 In order to remove the remaining stub, cut from below
about 1/3 into the remaining branch close to the trunk.
 Cut into the branch from above until the branch has been
removed completely.
 WARNING: Do not remove free-hanging branches from
below.
 Always stand at the side of the tree during felling (not in
front!)
 Decide the felling direction of the tree by considering the
wind, lean of the tree, location of heavy branches, ease of
job after felling and other factors.
The felling notch is cut on this side of the trunk.
 First cut 1/3 of the trunk diameter horizontally into the tree
at the intended felling notch (Fig.17 No.1).
 Now cut the second part of the felling notch from above at
an angle of 45 degrees to the rst cut (Fig.17 No.2).
 Now make the felling cut exactly opposite to the felling
notch. The felling cut must run horizontal and at a level
slightly higher than the bottom of the felling notch (Fig.17
No.3).
 Do not cut completely through the tree. Leave about 1/10
of the trunk diameter.
 Put wedges into the felling cut to bring the tree to fall
(Fig.17 No.4). Note the felling direction of the tree (Fig.17
No.5).
 WARNING: When felling a tree, be sure to warn neigh-
boring workers of the danger.
CUTTING A LOG LYING ON THE GROUND (Fig.18)
Saw down halfway, then roll the log over and cut from the
opposite side.
CUTTING A LOG HANGING OFF THE GROUND (Fig.16)
 If cutting in area A (see gure 16), saw up from the bot-
tom one-third and nish by sawing down from the top. If
cutting in area B, saw down from the top one-third and nish
by sawing up from the bottom.
 This technique must be following to ensure the chain
bar does not jam. If the chain saw does become jammed,
switch it o󰀨 immediately. Use wedges to free the bar.

CUTTING THE LIMB OF A FALLEN TREE (Fig.19)
 Before starting work, check the direction of bending force
inside the log to be cut. Then make the initial cut from the
bent side (Fig.19 No.1) and nish by sawing from the oppo-
site side (Fig.19 No.2). Always nish cutting from the oppo-
site side of bending direction to prevent the guide bar from
being caught in the cut.
 WARNING: 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 bres is released.
MAINTAINANCE AND CLEANING
In order to maintain your chain saw in proper working order,
perform the maintenance and checking operations described
in this manual at regular intervals. Leave all maintenance other
than the items listed in the Owner’s
Manual to your competent servicing dealer. Repairs and ser-
vicing must only be performed by authorized dealers and
service agents.
Before cleaning, inspecting or repairing the chain saw, make
sure that engine has stopped and is cool. Switch o󰀨 and dis-
connect the spark plug to prevent accidental starting during
maintenance and cleaning.
WARNING: The metal engine parts are at high temperatures
immediately
after stopping the engine.
MAINTENANCE AFTER EACH USE
Check all the chain saw parts for wear after every use,
particularly the chain, bar and sprocket.

Air lter
Clean air lter regularly. Unscrew air lter knob (Fig.10 No.4)
and remove air lter cover (Fig.10 No.5) and remove lter
(Fig.21). Dust on the lter surface can be removed by tapping
a corner of the lter against a hard surface. To clean dirt in the
mesh, split the lter into halves and brush in gasoline. When
using compressed air, blow from the inside. Remember to
wear safety goggles.
To assemble the lter halves, press the rim until it clicks. Note,
when installing the lter, make sure that the grooves on the
lter edge are correctly aligned with the intake hole on the
cylinder.
Fit new lter if damaged.
Oiling port
Dissemble the guide bar and check the oiling port for clogging
(Fig. 4).
Guide bar
When the guide bar is dissembled, remove sawdust in the bar
groove and the oiling port. Grease the nose sprocket from the
feeding port on the tip of the bar (Fig. 9).
Chain
Remove the chain and clean it if it is dirty, e.g. gumming with
resin. Place the chain in a vessel containing chain cleaner.
There after clean the chain with clean water. If the chain is not
used again immediately, it must be treated with oil or a custom
anti-corrosion spray.
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.
Oil level and lubrication
Check the oil level and lubrication after every use. Insu󰀩cient
oil and lubrication leads to damage to the chain, bar and en-
gine.
General
Check for fuel leakage, loose fasteners and damage to major
parts, especially handle joints and guide bar mounts. If any
damage is found, make sure to have it repaired before operat-
ing the chain saw again.
PERIODIC MAINTENANCE
Cylinder ns
NOTE: Block the air intake hole when cleaning cylinder ns.
Dust clogging between the cylinder ns will cause overheating
of the engine.
Periodically check and clean the cylinder ns after removing
the air lter and the cylinder cover (Fig.22). When re-fastening
the cylinder cover, make sure that switch wires and grommets
are positioned correctly in place.
Fuel lter
Replace every 12 months.
(a) Using a wire hook, take out the lter from the fuel tank rell-
ing inlet (Fig.10, No.12).
(b) Disassemble the lter and wash with gasoline, or replace
with new one if needed.
NOTE
After removing the lter and when assembling the lter, take
care not to allow lter bres or dirt inside the suction pipe.
Silencer
The silencer may become blocked by deposits over a period of
time and must be removed to be cleaned or replaced.

Chain oil tank
With a wire hook, take out the oil lter through the oil ller port
(Fig.10 No.13) and clean in gasoline. When putting the lter
back into the tank, make sure that it is positioned in the front
right corner. Also clean out any dirt in the tank.
Spark plug
Check every 12 months or if starting problems are experi-
enced. When the engine is cold, remove the plug cap and un-
screw the spark plug with a suitable spark plug socket. Clean
the electrodes with a wire brush and reset the gap to 0.65 mm
when necessary (Fig.23). If the electrodes are excessively
soiled or worn then replace with an equivalent new spark plug
(e.g. BM6A). Excessive soiling may be due to a) too high ratio/
poor quality 2-stroke oil or b) clogged air lter.
Replace spark plug and screw in by hand to avoid stripping of
thread, then tighten with socket.
Sprocket (Fig. 5)
Check for cracks and for excessive wear interfering with the
chain drive. If the wearing is observed, replace. Never t a new
chain on a worn sprocket, or a worn chain on a new sprocket.
Front and Rear dampers
Replace rubber dampers if they are cracked or appear peeled.
Saw Chain:
WARNING
It is very important for smooth and safe operation to keep the
cutters always sharp.

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.
Cutter setting standards:
WARNING: Be sure to wear safety gloves.
Before ling:
  Make sure the saw chain is held securely (Fig.24).
  Make sure the engine is stopped.
  Use a round le of proper size for your chain.
Chain type: K2
File size: 3/16 in (4.76mm)
Place your le on the cutter and push straight forward. Keep
the le position as illustrated (Fig.25)
After every cutter has been set, check the depth gauge and le
it to the proper level as illustrated (Fig.26).
WARNING: Be sure to round o󰀨 the front edge to reduce the
chance of kickback or tie-strap breakage.
Make sure every cutter has the same length and edge angles
as illustrated
(Fig.26).
Referring to gure 26:
(1) Appropriate gauge checker.
(2) Make the shoulder round
(3) Depth gauge standard
(4) Cutter length
(5) Filing angle
(6) Side plate angle
(7) Top plate cutting angle
Guide Bar
Reverse the bar occasionally to prevent partial wear.
The bar rail should always be a square. Check for wear of the
bar rail. Apply a ruler to the bar and the outside of a cutter. If a
gap is observed between them, the rail is normal. Otherwise,
the bar rail is worn. A worn bar needs to be repaired or re-
placed (Fig.27).
Referring to gure 27:
1. Ruler
2. Gap
3. No gap
4. Chain tilts
GENERAL CLEANING
 Always remove wood shavings and oil from the chain saw
after use. Clean the chain saw by brushing away dirt and
waste residue that may be caught the machine. Wipe the
chainsaw clean with a damp cloth or hand brush
.
DO NOT use running water, solvents, strong detergents or
a high pressure washer to clean. (Use a mild detergent and
sponge to clean the plastic surfaces.)
Pay particular attention to the air intake area, keeping it free of
debris
Switch the chain saw o󰀨 immediately if the machine starts to
shake or produce abnormal noise.
NOTE: It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel lter,
fuel hose, or fuel tank during storage. Alcohol blended fuels
(called gasohol or using ethanol or methanol) can attract mois-
ture which leads to fuelmixture separation and formation of
acids during storage. Acidic gas can damage the engine.

TRANSPORTATION AND STORAGE
 WARNING: Stop the engine and allow the chain saw to cool
before storing or transporting in a vehicle.
 Always carry the unit with the engine stopped, the guide bar
covered and mu󰀪er away from your body.
 Clean the unit before storing.
 Store the chain saw and fuel where fuel vapours cannot
reach sparks or open ames.
 If chain saw is unused for more than 2 months or being
transported, then empty the fuel tank. Before storage allow the
engine to cool. Store the unit indoors in a dry, ventilated and
locked place, out of reach of children.
 Store the chain saw with all guards in place.
