OPERATION

WARNING

KICK-BACK occurs when the moving chain

contacts an object at the upper portion of the tip

of the guide bar or when the wood closes in and

pinches the saw chain in the cut. Contact at the

upper portion of the tip of the guide bar may

cause the chain to dig into the object and stop

the  chain  for  an  instant.  The  result  is  a

lightningfast, reverse reaction which kicks the

guide bar up and back towards the operator. 

If the saw chain is pinched along the top of the

guide bar, the guide bar can be driven rapidly

back towards the operator. Either of these

reactions may cause you to lose control of the

saw, which could result in serious injury. 

Do not rely exclusively upon the safety devices built into

your saw. As a chainsaw user, you should take several

steps to keep your cutting jobs free from accident or injury.

KICK-BACK PRECAUTIONS (Fig. 4 & 5)

Rotational kick-back (

A

) occurs when the moving chain

contacts an object at the Kick-back Danger Zone (

B

of the guide bar. 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 may result in serious injury.

FUEL AND REFUELLING

HANDLING THE FUEL SAFELY

WARNING

Always  turn  off  engine  before  refuelling. 

Never add fuel to a machine with a running or

hot engine. Move at least 15 m (50 ft.) from 

refuelling  site  before  starting  the  engine.

DO NOT SMOKE! Failure to heed this warning

can result in possible personal injury.

WARNING

Check for fuel leaks. If any are found, correct them

before using the saw to prevent fire or burn injury.

Always handle fuel with care. It is highly flammable.

Always refuel outdoors where there are no sparks

and flames. Do not inhale fuel vapour.

Do not let petrol or oil come in contact with your skin.

Keep petrol and oil away from the eyes. If petrol or oil

comes  in  contact  with  the  eyes,  wash  them

immediately with clean water. If irritation is still

present, see a doctor immediately.

Clean up spilled fuel immediately.

MIXING THE FUEL

This product is powered by a 2-cycle engine and

requires pre-mixing petrol and 2-cycle oil. Pre-mix

unleaded petrol and 2-cycle engine oil in a clean

container approved for petrol.

This engine is certified to operate on unleaded petrol

intended for motor vehicle use with an octane rating

of 87 ([R + M] / 2) or higher.

Do not use any type of pre-mixed petrol/oil from fuel

service stations. This includes the pre-mixed petrol/oil

intended for use in mopeds, motorcycles etc.

Use high a quality 2-cycle self-mixing oil for air-

cooled engines. Do not use motor vehicle oil or 

2-cycle outboard oil.

Mix 2% oil into the petrol. This is a 50:1 ratio.

Mix the fuel thoroughly and also each time before

refuelling.

Mix in small quantities. Do not mix quantities larger

than  usable  in  a  30  day  period. A 2-cycle  oil

containing a fuel stabiliser is recommended.

FILLING THE TANK (Fig. 6)

Refer to “Specific Safety Rules - Refuelling” earlier in this

manual for additional safety information.
1.  Clean surface round fuel cap to prevent contamination.

2.  Loosen fuel cap slowly to release pressure and to

keep fuel from escaping around the cap.

3.  Carefully pour fuel mixture into the tank. Avoid spillage.

4.  Prior to replacing the fuel cap, clean and inspect 

the gasket.

5.  Immediately replace fuel cap and hand tighten. 

Wipe up any fuel spillage. Move 9 m (30 ft) away

from refuelling site before starting engine.

NOTE

: It is normal for smoke to be emitted from a

new engine during and after first use.
