ASSEMBLY
6. Align the chain tensioning pin and the hole in
the bar and then fit the clutch cover and bar
fastening nuts finger tight only.
7. Adjust the chain tension screw (Fig.5) so that if
the chain is pulled down with the fingers at the
centre of the bar the gap between the chain
and the bar is 2 to 3 mm. (Fig.6)
8. At this point double check to see if the chain is
sitting correctly on the sprocket and bar. Do not
proceed until they are sitting correctly. Firmly
tighten the bar fastening nuts.
WARNING.
Saw chain stretches during
use, particularly when it is new, and it will
occasionally be necessary to adjust and
tighten it. New chain will require adjust
ment in less than 5 cuts. Re adjust it as
often as necessary.
CAUTION.
For your own safety, always
stop the engine before performing any
adjustments. Always wear gloves when
working on the chain. Do not operate
with a loose chain.

FUEL MIXING AND CHAIN LUBRICATION
FUEL AND LUBRICANT
• The fuel for this machine is a mixture of
unleaded petrol and an air-cooled 2-stroke oil
of a reputable brand name. Do not use fuel
containing methyl alcohol or more than 10%
ethyl alcohol.
• Recommended mixture ratio 25:1.
• Do not mix directly in the engine fuel tank. Mix
fuel with 2-stroke oil in an approved container,
shake gently and ensure a thorough mix, and
pour into the fuel tank. Any spilled fuel should
be wiped clean immediately.
• Do not store unused fuel for too long as the
petrol and oil mixture separates, causing
damage to the engine.
WARNING.
Never use raw fuel with out
oil in your unit. This will cause permanent
engine damage and void the your
warranty for that product. Never use a
fuel mixture that has been stored for over
90 days.
WARNING.
The 2 stroke oil must be a
premium grade oil for 2-cycle air cooled
engines and must be mixed at a 25:1
ratio with the fuel. Mixing the fuel at a
greater ratio than 25:1 provides
insufficient lubrication and will cause
engine damage and voids your engines
warranty.
WARNING.
Handle petrol with care as it
is highly flammable.
CHAIN LUBRICANT
• Proper lubrication of the chain while in
operation reduces the friction between the
chain and the guide bar and assures a longer
tool life. Use only special chain oil of a high
quality for this purpose.
• Do not use any waste or reclaimed oil as this
could cause various problems with the oil
pump.
• Whenever you refill the fuel tank with petrol you
must also top up the level of chain oil in the
chain oil tank.
