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 SAW CHAIN AND GUIDE BAR

See page 343, Fig. 5 - 8.

1.  Stop the product. Wear protective gloves.
2.  Disengage the chain brake.
3.  Unscrew the guide bar locking knob and remove the

sprocket cover.

4. Attach the guide bar and chain tension assembly to the

chain saw. Lower the guide bar so that the bolt goes
through the hole in the bar and chain tension assembly.

5. The saw chain should face in the direction of chain

rotation. If they face backwards, turn the loop over.

6. Place the loop around the drive sprocket. Then place

the chain drive links into the bar groove. If needed,
rotate the chain tension assembly to apply some
tension to the chain which will help keep it in place.

7. Replace the sprocket cover.
8. Adjust the chain tension. Refer to the “Adjusting the

chain tension” section.

ADJUSTING THE CHAIN TENSION

See page 356

1. Loosen the guide bar locking knob slightly by turning it

counterclockwise.

2. To increase the chain tension, turn the chain tensioner

adjustment ring clockwise and check the chain tension
frequently. To reduce the chain tension, turn the chain
tensioner adjustment ring counterclockwise and check
the chain tension frequently.

3. The chain tension is correct when the gap between the

cutter in the chain and the bar is between 3 mm - 4
mm. Pull the chain in the middle of the lower side of the
bar downwards (away from the bar) and measure the
distance between the bar and the chain cutters.

4. Tighten the guide bar locking knob 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

in these instructions.

OPERATING THE PRODUCT

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 343.

■

Clean the surface around the fuel cap to prevent
contamination.
