Fuel mixture
The engine of the chain saw is a high-efficiency two-stroke engine.
It runs on a mixture of gasoline and two-stroke engine oil.
The engine is designed for unleaded regular gasoline with a min.
octane value of 91 ROZ. In case no such fuel is available, you can
use fuel with a higher octane value. This will not affect the engine.
In order to obtain an optimum engine output and to protect
your health and the environment use unleaded fuel only.
Gasoline which contens alcohol should not used in MAKITA
products.
For lubricating the engine use a high-performance two-stroke
engine oil (quality grade JASO FC or ISO EGD specifications),
which is added to the fuel. The engine has been designed for
use of MAKITA HP 100 high-performance two-stroke engine oil
and a mixture ratio of only 100:1 to protect the environment. In
addition, a long service life and reliable operation with a minimum
emission of exhaust gases are ensured.
MAKITA HP 100 high-performance two-stroke engine oil is avail-
able in the following sizes:
0.5
l
order number 980 008 609
MAKITA high-performance two-stroke engine oil is available in
the following sizes to suit your individual requirements:
1
l
order number 980 008 607
100 ml
order number 980 008 606
In case MAKITA high-performance two-stroke engine oil is not
available, it is urgently recommended to use a mixture ratio of 40:1
with other two-stroke engine oils, as otherwise optimum operation
of the engine cannot be guaranteed.
The correct mixture ratio:
50:1
when using MAKITA high-performance two-stroke engine
oil, i. e. mix 50 parts gasoline with 1 part oil.
100:1 when using MAKITA HP 100 high-performance two-stro-
ke engine oil, i. e. mix 100 parts gasoline with 1 part oil.
40:1
when using other two-stroke engine oils, i. e. mix 40 parts
gasoline with 1 part oil.
Handling and storage
Utmost care is required when handling with fuel. Fuel can contain
substances which have a behavior similar to that of solvents. Fill
the tank only outside or ventilated rooms. Do not inhale vapors,
avoid any fuel contact with your skin. For preparing the fuel-oil
mixture first mix the entire oil quantity with half of the fuel required,
then add the remaining fuel. Thoroughly shake the mixture before
filling it into the chain saw tank.
It is not wise to add more engine oil than specified to ensure safe
operation. This will only result in a higher production of combus-
tion residues which will pollute the environment and clog the
exhaust channel in the cylinder as well as the muffler. In addition,
fuel consumption will rise and performance will decrease.
Fuel cannot be stored for an unlimited period of time. Buy only as
much as will be consumed in 4 weeks. Use only approved and
marked containers for transport and storage.
B
Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
flung off the chain too quickly.
We recommend the use of chain oil which is bio-degradable in
order to protect the environment. The use of bio-degradable oil
may even be required by local regulations.
The chain oil BIOTOP sold by MAKITA is made of special
vegetable oils and is 100% bio-degradable. BIOTOP has been
granted the "blue angel" (Blauer Umweltschutz-Engel) for
being particularly environment-friendly (RAL UZ 48).
BIOTOP chain oil is available in the following sizes:
1 l
order number 980 008 610
5 l
order number 980 008 611
Bio-degradable oil is stable only for a limited period of time. It
should be used within 2 years from the date of manufacture
(printed on the container).
Important note on bio-degradable chain oils:
If you are not planning to use the saw again for an extended
period of time (longer than the expiration date of the chain oil),
empty the oil tank and put in a small amount of regular engine
oil (SAE 30), and then run the saw for a time. This is necessary
to flush out all remaining bio-degradable oil from the oil tank,
oil-feed system, chain and guide bar, as many such oils tend
to leave sticky residues over time, which can cause damage
to the oil pump or other parts.
The next time you use the saw, fill the tank with BIOTOP chain
oil again.
waste oil
C
NEVER USE WASTE OIL
Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
Residues in waste oil result in a high degree of wear and tear
at the oil pump and the sawing device.
In case of damage caused by using waste oil or unappropriate
chain oil the product guarantee will be null and void.
Your salesman will inform you about the use of chain oil.
