GB
Always check that the chain oil reservoir is properly filled before use.
• Always use good quality, chain oil (30 weight). Do not attempt to use
motor oil, 2 stroke oil, or any other type of alternative lubricant.
• To add oil, stop the engine and remove the oil filler cap (5). Fill the
reservoir with 260ml of oil. Replace the filler cap.
• Start the engine, and run the saw with the chain approx 200mm from the
ground. Oil should be thrown off of the chain onto the ground.
• If oil is not delivered properly, use the adjustment screw which can be
located on the underside of the main body next to the clutch assembly.
NOTE: The delivery passageways may need cleaning. Stop the engine,
remove the side cover from the machine, remove the cutting bar, and
clean all wood chips or dust from the machine. Reassemble and test.
• Do not allow the reservoir to run dry during use.
Fuelling
• Always refuel in a safe place, well away from the work area, and any
source of heat or ignition. Avoid any contact with the fuel. DO NOT
SMOKE.
• Only add fuel when the engine is stopped, and has cooled fully.
• Fuel should always be pre mixed, do not mix fuel in the petrol tank. Only
mix as much fuel as you intend to use. Use 25 parts unleaded petrol to
every 1 part two stroke oil. Always use proper 2 stroke oil.
• Tip the chainsaw onto it’s side, petrol filler cap (9) uppermost.
• Remove the petrol filler cap (9), fill the tank with fuel mixture to the level
of the filler hole.
• Replace the filler cap.
• Make sure that any fuel spillage is properly cleaned up.
• Move the chainsaw well away from the fuelling area before starting
engine.
• Keep extra fuel well away from the work area.
Starting the engine
WARNING: This chainsaw will produce toxic fumes as soon as it is running.
Never attempt to start the engine indoors, or in any kind of enclosed space.
Always wear proper safety protection, use of this tool requires goggles,
gloves, ear defenders, face mask, and sturdy clothing. Wearing a hard hat,
and safety boots, is also advisable.
• Place the chainsaw onto the ground, ensuring that the chain blade is not
in contact with any object.
• Pull the choke lever (6) out (If the engine is already warm, push the choke
lever in).
• Set the ignition switch (9) to the “ON” position.
• Press down on the front handle (4) to steady the chainsaw. Grip the recoil
starter (11), and pull gently to remove slack.
• Pull the starting handle firmly to start the engine. Do not wrap the starter
cord around your hand, always guide the cord back into the casing.
• The engine should start after a few pulls.
• As the engine warms, push the choke lever (6) in.
NOTE: The engine may not require and choke to start even if cold. If you are
finding it difficult to start, push the choke lever fully in and try again.
Stopping the engine
• Release the trigger throttle (8), and allow the engine to idle.
• Move the ignition switch (9) to the “OFF” position.
• The engine will stop.
Engine adjustments
• When adjusted properly, the engine should idle smoothly and accelerate
without hesitation. The saw chain should not move when the engine is
idling.
Checking chain brake operation
• This machine is equipped with a chain brake system. This is designed
to stop the chain in the event of a severe kickback. The chain brake is
activated when contact with the users hand or arm knocks the blade
guard (3) forwards.
• The chain brake should be checked for correct operation before each
use.
• To check the chain brake operation, run the machine at full speed, and
push the blade guard (3) forwards. The chain should stop immediately
(less than 1 second). If the chain brake does not operate satisfactorily, the
saw should be serviced at an authorised service centre.
• To reset the chain brake, return the blade guard (3) to its rearward
position.
NOTE: Do not run the engine with the chain brake engaged for more than a
few seconds. Permanent damage to the brake mechanism may occur.
Using Your Chainsaw
WARNING: Using a chainsaw correctly is a technical skill. A chainsaw used
incorrectly can be highly dangerous. The information presented below is
general guidance only. If you are not entirely confident in your ability to use
this tool safely
DO NOT USE.
Cutting
• Always maintain a secure footing, if it is not possible to reach the cutting
area from a secure position, do not cut.
• Carefully asses the safest way to cut (see “avoiding kickback” section
below). Every cut made using a chainsaw is unique, every cut presents
its own safety considerations. Always consider how the wood may move
or fall when it has been cut. Make sure that the wood will not fall or roll
towards you, and that the blade will not become trapped.
• Always hold the saw securely, keeping your left arm as straight as is
practical. Do not raise the saw above chest height.
• With the saw running at full speed, lower the blade into the wood. Always
use the part of the cutting bar nearest to the body of the machine.
• Allow the blade to work steadily through the wood. It should not be
necessary to use force to make the saw cut. Slow cutting indicates a
blunt blade.
• Do not allow the blade to contact the ground, or any object other than
that which you intend to cut.
• Release the trigger throttle (8) as soon as the cut is complete. Running
the engine at full throttle without a load will cause rapid wear to the
engine, saw chain, and guide bar.
Avoiding kickback
• Kickback is usually caused when the chain teeth near the tip of the
cutting bar “bite” into a solid object. The resulting reactionary force may
make the saw violently accelerate up and back, towards the user.
• Modern chainsaws have numerous features designed to reduce
kickback, but careful use is the best guarantee of safety.
• Always use a sharp chainsaw blade. Blunt blades are more likely to jam
in the wood.
• Always cut at full speed. At part speed the saw may not be able to drive
the blade through the wood, resulting in jamming and kickback.
• Check the cutting area for foreign bodies. Contacting wire, concrete,
brick, or other materials can cause sudden loss of control.
• Check behind the cutting area. If the teeth at the tip of the cutting bar
make contact with other wood, they will drive the chainsaw up, and back.
• Do not attempt to make cuts through material thicker than recommended
above. The recommended cutting length is intentionally less than the
overall bar length so that the teeth at the bar tip are not in the wood.
• Always hold the saw securely, keep your left arm as straight as is
practical when cutting.
• A properly functioning chain brake is important is preventing injury in the
event of kickback. Always test the chain brake before use.
Maintenance
Always stop the engine, and allow to cool fully, before performing any
cleaning or maintenance.
Blade maintenance
• After every use, unsure that all waste material is removed from the blade.
• If cutting speed is reduced, or if cutting produces powder rather than
wood chips, the blade is probably blunt. The blade should be regularly
sharpened using an appropriately sized chainsaw file.
• To maximise the service life, periodically turn the guide bar over when
