A new saw chain will stretch, so it is impor-
tant to readjust the chain at short intervals
(around 5 cuts) when you fi rst start using it.
The intervals get longer as operating time
increases.
Note: If the saw chain (3) is TOO LOOSE or TOO
TAUT, the drive wheel, chain bar, chain and crank
shaft bearing will suff er premature wear. Fig. 3B
shows the correct tension A (when cold) and ten-
sion B (when warm). Fig. C shows a chain that is
too loose.
5.3 Fuel and lubrication
Fuel
Use regular grade unleaded gasoline mixed with
1:40 custom 2-cycle engine oil for best results.
Mixing fuel
Mix fuel with 2 cycle oil in an approved container.
Shake container to ensure thorough mix.
Note: Never use straight gasoline in your unit.
This will cause permanent engine damage and
void the manufacturer's warranty for that product.
Never use a fuel mixture that has been stored for
over 90 days.
Note: If 2-cycle lubricant is to be used, it must be
a premium grade oil for 2-cycle air cooled engi-
nes mixed at a 1:40 ratio. Do not use any 2-cycle
oil product with a recommended mixing ratio of
1:100. If insuffi cient lubrication is the cause of en-
gine damage, it voids the manufacturer's engine
warranty for that occurrence.
Recommended fuels
Some conventional gasolines are being blended
with oxygenates such as alcohol or an ether com-
pound to meet clean air standards. Your engine is
designed to operate satisfactorily on any gasoline
intended for automotive use including oxygenated
gasolines. It is recommended to use unleaded
petrol as fuel.
Lubrication of chain and chain bar
Whenever you refi ll the fuel tank with petrol you
must also top up the level of chain oil in the chain
oil tank. It is recommended to use standard chain
oil.

Engine pre-start checks
Danger: Never start or operate the saw unless
the bar and chain are properly installed.
1. Fill the fuel tank (21) with correct fuel mixture
(Fig. 4).
2. Fill the oil tank (22) with chain oil (Fig. 4).
Once you have fi lled the chain and oil tank, tigh-
ten the tank cover securely by hand. Do not use
any tools to do so.
6. Operation
Before you use the saw, check it for damage.
If you discover any damage, do not use it. The
chainsaw may be started only when the chain
brake is engaged. The chain brake is engaged
when the brake lever (6) is pushed forward.
Explanation of how it works: refer to Che-
cking the chain brake - Static check.
6.1 Chain brake
The chainsaw is fi tted with a chain brake which
reduces the risk of injury caused by the danger of
kickback. The brake is engaged when pressure is
applied to the hand guard (6), e.g. when the hand
of the person operating the chainsaw strikes the
hand guard (6) if kickback occurs. When the bra-
ke is engaged, the chain (3) stops abruptly.
Warning: The chain brake is intended to reduce
the risk of injury due to kickback; however, it is un-
able to provide adequate protection if the saw is
used carelessly. You must check the operation of
the chain brake on a regular basis. Test the chain
brake before the fi rst cut, after several cuts, after
maintenance is done on the chainsaw and if the
chainsaw has been subjected to strong impact or
if it has been dropped.
