Operation
Fuel/oil mixture
The hedge trimmer is powered by a two-stroke motor with a
high level of performance.
This motor is operated using a mixture of fuel and two-
stroke oil. The motor is designed for lead-free regular petrol
with an octane rating of ROZ 91. If this fuel is not available,
you can use a fuel with a higher octane rating. This does
not damage the motor, but the operating behaviour may be
poorer.
Similar problems arise if leaded fuel is used. In order to
achieve optimum operation of the motor, and to protect
your health and the environment, only lead-free fuel should
be used.
The motor is lubricated by the two-stroke oil which is mixed
with the fuel. The motor is designed for operation with solo
by AL-KO two-stroke oil in a mix ratio of 40:1 (environmen-
tal protection). The low mix ratio guarantees minimum pol-
lutant emission simultaneously with long working life and
reliable operation. The mix ratio of 40:1 (solo by AL-KOtwo-
stroke oil) must be complied with, otherwise reliable opera-
tion of the hedge trimmer cannot be guaranteed.
The correct mix ratio:
Carburettor fuel:
Prescribed two-stroke oil = 40: 1 or
two-stroke oil from another manufacturer = 25: 1 recom-
mended
To prepare the mixture, in an approved container which fulfils or exceeds all locally app-
licable requirements, first mix the whole amount of oil with half the required amount of fuel.
Then add the rest of the fuel.
Mix the mixture thoroughly before adding it to the tank of the hedge trimmer.
In order to ensure reliable operation, do not add more motor oil than specified. Otherwise,
the result is just the creation of more combustion residue which pollutes the environment
and blocks the exhaust duct and the silencer. In addition, the fuel consumption rises and
the performance decreases.
Handling mineral oil products
Extreme care is required when handing fuels. Fuels may contain substances which are similar to sol-
vents. Refuel the machine exclusively in a well ventilated location in the open air. Do not inhale the fuel
vapours, and avoid any skin contact with fuels and oils.
If the skin comes into repeated contact with such substances over an extended period of time, it dries
out.
This can result in a very wide number of skin disorders. There have also been reports of allergic reac-
tions.
Eye irritations can occur if oils, fuels, etc. get into the eyes.
If this occurs, flush the eyes immediately with clean water. If the eye irritations continue, contact a doc-
tor immediately.
