a) With the saw running, keep all parts of the body away from the saw chain. Before
starting the saw, make sure that the saw chain does not touch anything. When
working with a chainsaw, a moment of carelessness may cause clothing or body
parts to be caught by the saw chain.
b) Always hold the chainsaw with your right hand on the rear handle and your left
hand on the front handle. Holding the chainsaw in the reverse working position
increases the risk of injury and must not be done.
c) The power tool may only be held on the insulated grip surfaces in case the saw
chain touches covered cables. Saw chains touching a live wire will energise metal
parts of the power tool and could cause an electric shock to the operator.
d) Wear eye and ear protection. Additional protective equipment for head, hands,
legs and feet is recommended. Suitable protective clothing reduces the risk of
injury from flying debris and accidental contact with the saw chain.
e) Do not work on a tree with the chainsaw. Operation on a tree may result in injury.
f) Always make sure you stand firmly and use the chainsaw only if you stand on firm,
safe and level ground. Slippery ground or unstable surfaces such as a ladder can
lead to loss of balance or control over the chainsaw.
g) When cutting a live branch, expect it to spring back. If the tension in the wood
fibres is released, the tensioned branch may hit the operator and/or rip the
chainsaw out of control.
h) Be particularly careful when cutting undergrowth and young trees. The thin
material may get caught in the saw chain and hit you or upset your balance.
i) Carry the chainsaw by the front handle when switched off, with the chain facing
away from your body. Always remove the protective cover when transporting or
storing the chainsaw. Careful handling of the chainsaw reduces the likelihood of
accidental contact with the running chain.
j) Follow instructions for lubrication, chain tension and changing accessories. An
improperly tensioned or lubricated chain can either break or increase the risk of
recoil.
k) Keep handles dry, clean and free of oil and grease. Greasy, oily handles are slippery
and cause loss of control.
l) Only saw wood. Do not use the chainsaw for work for which it is not intended. Do
not use the chainsaw to saw plastic, masonry or construction materials that are
not made of wood. Using the chainsaw for work other than that for which it was
intended can lead to dangerous situations.
INSTRUCTION
Note:
•Read all safety warnings, instructions and specifications provided with this
tool.
•Failure to follow all instructions listed below may result in injury.

1. Avoiding kickback
Kickback may occur if the tip of the guide bar touches an object or if the wood bends and
the saw chain become stuck in the cut. In some cases, contact with the tip of the bar may
result in an unexpected rearward reaction by hitting the guide bar upwards and in the
direction of the operator.
Jamming the saw chain at the top of the guide bar can quickly push the bar back in the
operator's direction.
Any of these reactions can cause you to lose control of the saw and potentially seriously
injure yourself.
Do not rely solely on the safety devices built into the chainsaw. As a chainsaw user, you
should take various measures to avoid accidents and injuries.
A kickback is the result of incorrect or faulty use of the power tool. It can be prevented by
taking appropriate precautions as described below:
a) Hold the saw firmly with hands, thumb and finger enclosing the handles of the
chainsaw. Bring your body and arms into a position where you can withstand the
recoil forces. If appropriate measures are taken, the operator can control the recoil
forces. Never release the chainsaw.
b) Avoid abnormal posture and do not saw above shoulder height. This will prevent
accidental contact with the bar tip and allow better control of the chainsaw in
unexpected situations.
c) Always use replacement bars and saw chains specified by Kogan.com. Incorrect
replacement bars and saw chains can cause the chain to tear and/or kickback.
d) Follow the instructions for sharpening and maintaining the saw chain. Depth
limiters that are too low increase the tendency to kickback.
Note:
Observe the safety and operating instructions in the separate operating instructions for
the battery and charger.
WARNING: This power tool generates an electromagnetic field during

Some safety precautions must be observed when using equipment to prevent injury and
damage:
•Read the operating instructions carefully and follow their instructions.
Use these instructions to familiarise yourself with the device, its correct use and
safety regulations.
•Keep these in a safe place so that the information is available to you at all times
•If you should hand over the device to another person, hand over these operating
instructions.
1. Mounting the guide bar and saw chain
a) Unpack all parts carefully and check for completeness.
b) Loosen the fixing screw for the chain wheel cover (Fig. 3).
c) Remove the chain wheel cover (Fig. 4).
d) Place the chain in the circumferential groove of the saw chain as shown (Fig. 5a).
e) Insert the saw chain and guide bar into the chainsaw holder as shown. Guide the
chain around the sprocket (Fig. 5b).
f) Fit the chain wheel cover (Fig. 6a) and secure with the fixing knob (Fig. 6b).
Do not tighten the fixing screw until the chain tension has been adjusted.
2. Tensioning the saw chain
Watch your step.
Always switch off the device and remove the battery from the device before checking and
adjusting.
Always wear protective gloves when working on the chain saw to avoid injury.
a) Loosen the fixing knob for the chain wheel cover a few turns (Fig. 3).
b) Turning to the right increases the chain tension, turning to the left reduces the
chain tension. The saw chain is correctly tensioned when it can be lifted by approx.
3-4mm in the middle of the sword (Fig.8).
c) Turn the knob clockwise to guide the saw chain (Fig. 6b).
All chain links must lie properly in the guide groove of the guide bar.

Tips for tensioning the chain:
•The saw chain must be correctly tensioned to ensure safe operation. You will see
the optimum tension when the saw chain can be lifted by 3-4mm in the middle of
the sword.
•Since the saw chain heats up as a result of sawing and changes its length as a
result, check the chain tension every 10 minutes and adjust it if necessary. This is
especially true for new saw chains.
•After finishing work, relax the saw chain as it shortens when it cools down. This will
prevent the chain from being damaged.
3. Saw-chain lubrication
Always switch off the device and remove the battery from the device before checking and
adjusting the chain. Always wear protective gloves when working on the chain saw to avoid
injury.
Observe temperature conditions.: Different ambient temperatures require lubricants with
very different viscosity. At low temperatures, you need thin oils (low viscosity) to produce a
sufficient lubricating film. If you use the same oil in summer, it would be liquefied further by
the higher temperatures alone. This can cause the lubricating film to break off, overheating
the chain and damaging it. Lubricating oil also burns and leads to unnecessary pollution.
4. Filling the oil tank
a) Place the saw chain on a level surface.
b) Clean the area around the oil tank cover and then open it. (Fig. 9b)
c) Fill the tank with saw chain oil. Ensure that no dirt gets into the tank so that the oil
nozzle is not blocked.
d) Close the oil tank cap.
ATTENTION: Never operate the chain without saw chain oil. Using the
chainsaw without saw chain oil or with an oil level below the minimum mark
(Fig. 9) will damage the chainsaw.
