GB) BASIC SAFETY PRECAUTIONS
BASIC PRECAUTIONS FOR PERSONAL SAFETY
• Chain saws are designed for the purpose of cutting wood only. Any misuse of the product might cause serious injury or death.
• Use safety footwear, snug-fitting clothing, and eye, hearing and head protection.
• Wear non-slip gloves to improve your grip. Do not wear scarfs, jewelry, or neckties which could be drawn into the engine or catch on the chain
or underbrush.
• Always hold the chain saw with both hands when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles.
• Protect your hearing. Guard against the effects of a long or continuous exposure to noise, such as involved in the operation of a chain saw. Wear
hearing protection devices.
• Never operate a chain saw when you are fatigued, ill or under influence of alcohol or other drugs.
• Keep all parts of your body away from the saw chain when the engine is running.
• Exposure to vibrations through prolonged use of gasoline powered hand tools could cause blood vessel or nerve damage in the fingers, hands,
and wrists of people prone to circulation disorders or abnormal swellings. Prolonged use in cold weather has been linked to blood vessel damage
in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in
the fingers, hands, or wrists, discontinue the use of this tool and seek medical attention.
• Avoid breathing exhaust gas, chain lubrication oil mist or saw dust. Only operate the chain saw in well ventilated areas.
BASIC PRECAUTIONS WITH CHAIN SAWS
• Always carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.
• When transporting your chain saw, use the appropriate guide bar scabbard.
• Always use caution when handling fuel. Move the chain saw at least 3 meters from the fueling point before starting the engine.
• Be ready to hold up the saw so it will not drop onto your leg when the cut is finished.
• Never make one-hand cuts because kickback, pinch, push or other reactions cannot be controlled as well with only one hand.
• Never let anyone use your chain saw who has not received adequate instructions in its proper use. This applies to rentals as well as privately
owned saws.
• Keep the handles dry, clean and free of oil or fuel mixture.
• Before you start the engine, make sure the saw chain is not contacting anything.
• Shut off the engine before setting down the saw. Do not leave the engine running unattended.
• Be sure that the chain stops moving when the throttle control is released.
• Do not adapt your powerhead to a bow guide or use it to power any attachments or devices not listed for your saw.
BASIC PRECAUTIONS ABOUT MAINTENANCE
• Never operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops
moving when the throttle control trigger is released.
• All chain saw service, other than items in the owner's manual Maintenance Intructions, should be performed by competent chain saw service
personnel. For example, improper repairs to the flywheel or clutch can cause serious injuries from exploding parts.
BASIC PRECAUTIONS IN CUTTING/WORK AREA
• Do not operate a chain saw in a tree unless you have been specifically trained to do so.
• Keep bystanders and animals out of the work area.
• Never start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
• 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.
• 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.
• Use only the product manufacturer's genuine replacement parts. Failure to do so may cause possible injury.

GB) ILLUSTRATION 2.
KICKBACK (A) occurs when the moving chain contacts an object at the
Kickback Danger Zone (B) of the guide bar zone. The result is a lightning
fast, reverse reaction which kicks the guide bar up and back towards the
operator. This reaction can cause loss of control which can result in
serious injury.

GB) FUELING
•This product is equipped with a 2-stroke engine which requires
2-stroke lubricating oil to be pre-mixed through the petrol.
•Use LEAD FREE PETROL (minimum 87 Octane).
•Do not use pre-mixed petrol/oil from petrol (fuel) service sta-
tions intended for use in mopeds, motorcycles, etc.
•Use a clean petrol container to mix the petrol with oil.
•Use high quality 2-stroke self mixing oil for air cooled engines
(do not use outboard or automotive oil). Mix in small quantities.
•Mix 2% oil into the petrol. This is a 50:1 ratio.
•Mix the fuel thoroughly and also each time before fueling.
•DO NOT use fuel mix that is older than 30 days old or engine
may not start.
FILLING TANK
1. Loosen fuel cap slowly. Rest the cap on a clean surface.
2. Carefully pour fuel into the tank. Avoid spillage.
3. Immediately replace fuel cap and hand tighten. Wipe up any fuel
spillage.
4. It is normal for smoke to be emitted from a new engine after first use.
NOTE: Always shut off engine before fueling. Never add fuel to a
machine with a running or hot engine. Move at least 3 meters (10
feet) from refueling site before starting engine. DO NOT SMOKE!

GB) FILLING THE TANK
GR)
GB) NOTE
Always clean sawdust from the filler area before loosening the cap.
Turn the cap only a fraction of a turn to let any pressure inside the
tank drop. Then it is safe to remove the cap completely.
Remove (unscrew) the Fuel Cap (A). Fill the fuel tank with Mixed Fuel (B).
Replace the Fuel Cap and close tightly. Wipe off any spilled fuel. Avoid
breathing gasoline fumes. DO NOT over-fill tank.

GB) WARNING
To avoid any fire hazard, move 3 meters minimum away from
where you fueled the engine. NEVER start engine in an enclosed
space. Never run the saw without the clutch drum in place.
Serious injury could result.
•Push Primer Bulb (A) until fuel is seen in the bulb.
•Push Switch (B) to the “I” RUN position.
•Push Choke Lever (C) to full position (D).
•While squeezing the trigger, hook Trigger Latch by pushing forward
and let go of the trigger. This latches the trigger for starting.
•Place the chain saw on level ground and ensure that the chain is not
contacting any foreign objects.
•Hold front handlebar on top (E).
•Slowly pull the starter grip out until you feel the starter engage, then
briskly pull straight up (see illustration). DO NOT pull to the end of
the rope. Hold onto grip during rewinding.
•Pull starter until engine tries to run. (No more than 6 pulls.)
•Move Choke Lever to half choke position (F) and pull starter until
engine runs.
•Move Choke Lever to run (G) position. Squeeze the trigger and then
release to unlatch the trigger.
•Now you can pick up the saw.
•To stop the engine, move Switch (B) to “O” STOP position.
NOTE
Restarting a recently run engine: The engine may still be warm enough
to start at idle without choking. If not, hold throttle open and go to half
choke (F). Use full choke (D) if necessary.

GB) BASIC CUTTING PROCEDURES
Practice cutting a few small logs using the following tech-
niques before you begin a major sawing operation
• Wear hearing and eye protection.
• Take the proper stance in front of the wood with the saw idling.
• Accelerate the engine to full throttle just before entering the cut
by squeezing the throttle trigger.
• Begin cutting with the saw against the log.
• Keep the engine at full throttle the entire time you are cutting.
• Allow the chain to cut for you; exert only light downward pressure.
• Release the throttle trigger as soon as the cut is completed,
allowing the engine to idle.
• DO NOT put pressure on the saw at the end of the cut.
• When felling, have the spiked bumper assembled to saw.

GB) AIR FILTER MAINTENANCE
For proper performance and long life, keep air filter clean.
TO INSPECT AND CLEAN OR REPLACE THE AIR FILTER
NOTE
Always clean the air filter before making any mixture adjustments of
the carburetor.
1. For access to the cylinder and carburetor area, loosen the three
screws holding the cylinder cover and remove the cover.
2. Before removing the air filter from the carburetor, blow or brush
as much loose dirt and sawdust from around the carburetor and
chamber as possible.
3. The air filter (A) is retained by two filter retainer screws (B).
Remove the screws and lift filter off of air filter bottom.
4. A light cleaning can be given to the filter assembly by tapping it
against a smooth, flat surface to dislodge most saw dust and dirt
particles.
5. For a more thorough cleaning, clean in a warm soapy water, rinse
and let dry completely. Reinstall air filter. Make sure that the tabs
on air filter are located in channels on the air filter bottom before
tightening filter retainer screws.
6. The pre-filter (C) should be cleaned every 25 hours or sooner,
if it becomes clogged. Remove the starter assembly and the fan
housing baffle for access to the pre-filter in the engine housing.
NOTE
If an air hose is used for drying, blow through both sides of
screen.
WARNING
Never run the engine without the air filter, serious damage can
result.
DANGER
Repairs to the clutch and flywheel should be performed only
by trained service personnel. If improper tools are used to
remove the flywheel or clutch, or if an improper tool is used to
hold the flywheel in order to remove the clutch, structural
damage to the flywheel could occur which could subsequently
cause the flywheel to burst and could result in serious injury.
WARNING
Never run the engine without the Air Filter.
Always clean the air filter before adjusting carburetor.
