Pay attention to the correct direction of the saw chain.
5.
Fit the chain cover to the power unit and fasten the nuts to finger tightness.
6.
While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until
the tie straps just touch the bottom side of the bar rail.
7.
Tighten the nuts securely with the bar tip held up (12 - 15 Nm), then check the chain for smooth
rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover
loose.
8.
Tighten the tensioner screw.
A new chain will expand its length is the beginning of use.
Check and readjust the tension frequently as a loose chain can easily
derail or cause rapid wear of itself and the guide bar.
Fuel and Chain Oil
Fuel is highly flammable. Avoid smoking or bringing any flames or sparks nearby.
•
Make sure you stop the engine and allow it to cool before attempting to refuel the unit.
•
Select an outdoor location with bare ground for refuelling. Once refuelled, move the unit
to a location at least 3 metres away from the refuelling point before attempting to start
the engine.
•
The engines are lubricated by oil specially formulated for air-cooled, 2-cycle gasoline
engine use. Use an anti-oxidant added quality oil, expressly labelled for air-cooled, 2-
cycle engine use.
•
Do not use BIA or TCW (2-stroke water-cooling type) mixed oil.
•
Recommended mixing ration is Fuel 25:Oil 1.
•
Exhaust emissions are controlled by the fundamental engine parameters and components
(eg carburettor, ignition timing and port timing), without addition of any major hardware,
or the introduction of an inert material during combustion.
•
These engines are certified to operate on unleaded fuel.
•
Ensure you use fuel with a minimum octane number of 89. Use of a fuel with a lower
octane levels than prescribed may create a danger of high engine temperatures, or
pistons seizing.
•
Poor quality fuel or oil may result in damage to the sealing rings, fuel lines or fuel tank.
How to Mix Fuel
Pay attention to agitation.
•
Measure out the quantities of fuel and oil to be mixed.
•
Put some of the fuel into a clean, approved fuel container.
•
Pour in all of the oil, then agitate well.
•
Pour in the rest of the fuel, then agitate again for at least one minute. As some oils may
be difficult to agitate depending on the oil ingredients, sufficient agitation is necessary
for the engine to be adequately protected. Be mindful that insufficient agitation will
increase the danger of early piston seizing due to an abnormally lean mixture.
•
Put a clear indication on the outside of the container to avoid confusing this mixture for
regular fuel or other containers.
Fuelling the Unit
•
Untwist and remove the fuel cap. Rest the cap on a dust free surface.
•
Put fuel into the fuel tank to 80% of the full capacity.
•
Fasten the fuel cap securely, then wipe any fuel spillages around the unit.
