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.

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 and the bar is about 3 - 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.
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 specifi 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
