ASSEMBLY

 WARNING

If any parts are damaged or missing do not operate the 
product until the parts are replaced. Failure to heed this 
warning could result in serious personal injury.

ASSEMBLING THE SAW CHAIN AND GUIDE BAR

See page 317 - 319.

1.  Wear protective gloves.
2.  Disengage the chain brake.
3.  Remove the bar mounting nuts using the combination 

wrench provided.

4.  Remove the chain cover.
5.  Remove the bar from the product.
6.  Put the chain in the correct direction onto the bar and 

make sure that the drive links are aligned in the bar 
groove.

7.  Attach the bar to the chain saw and loop the chain 

around the drive sprocket.

8.  Replace the chain cover and bar mounting nuts.
9.  Finger-tighten the bar mounting nuts. The bar must be 

free to move for chain tension adjustment.

10. Adjust the chain tension. Refer to the “Adjusting chain 

tension” section.

11. Hold the tip of the guide bar up and tighten the bar 

mounting nuts securely.

ADJUSTING THE CHAIN TENSION

See page 331.

1.  Turn the ignition switch to the “off“ position.
2.  Make sure the bar mounting nuts are loosened to 

finger-tight.

3.  To increase the chain tension, turn the chain tensioning 

screw clockwise and check the chain tension frequently. 
To reduce the chain tension, turn the chain tensioning 
screw counterclockwise and check the chain tension 
frequently.

4.  The chain tension is correct when the gap between 

the cutter in the chain a

nd the bar is about 3 - 4 mm. 

Pull the chain in the m

iddle of the lower side of the 

bar downwards (away from the bar) and measure the 
distance between the bar and the chain cutters.

5.  Tighten the bar mounting nuts by turning it clockwise.

NOTE

: The temperature of the chain increases during 

normal operation causing the chain to stretch. Check the 
chain tension frequently and adjust as required. A chain 
tensioned while warm may be too tight upon cooling. Make 
sure that the chain tension is correctly adjusted as speci

fi

 ed 

in these instructions.

OPERATION

FUEL AND REFUELLING

Handling the fuel safely

 WARNING

Always shut off engine before fuelling. Never add fuel to 
a machine with a running or hot engine. Move at least 
10 metres 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 product to prevent fire or burn injury.

■

Always handle fuel with care; it is highly flammable.

■

Always refuel outdoors away from potential sources of 
ignition, do not inhale fuel vapours.

■

Do not let petrol or lubricant come in contact with skin. 
If contact does occur wash immediately with soap and 
plenty of water.

■

Keep petrol and lubricant away from the eyes. If petrol 
or lubricant comes in contact with the eyes, wash them 
immediately with clean water. If irritation is still present, 
see a physician immediately.

Mixing the fuel

■

The product is powered by a 2-cycle engine and 
requires pre-mixing petrol and 2-cycle lubricant. Pre-
mix unleaded petrol and 2-cycle engine lubricant in a 
clean container approved for petrol.

■

This engine is certified to operate on unleaded petrol 
intended for automotive use with an octane rating of 91 
or higher.

■

Do not use any type of pre-mixed petrol/lubricant from 
fuel service stations; this includes the pre-mixed petrol/
lubricant intended for use in mopeds and motorcycles.

■

Use a high quality 2-cycle self-mixing lubricant for air-
cooled engines. Do not use automotive lubricant or 
2-cycle outboard lubricant.

■

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

■

Mix the fuel thoroughly and each time before fuelling.

■

Mix in small quantities. Do not mix quantities larger 
than usable in a 30-day period. A 2-cycle lubricant 
containing a fuel stabiliser is recommended.

NOTE:

 Fuel system damage or performance problems 

resulting from the use of an oxygenated fuel containing 
more than the percentages of oxygenates stated previously 
are not covered under warranty.

Filling the fuel tank

See page 319

■

Clean the surface around the fuel cap to prevent 
contamination.

■

Loosen the fuel cap slowly.
