Installation
Fuel
Environmental petrol
We recommend the use of premixed alkylate or
environmental petrol mixed with two-stroke oil 2%
(50:1).
NOTICE The machine is equipped with a two-
stroke engine and must always be run using a
mixture of petrol and two-stroke oil. It is important
to accurately measure the amount of oil to be
mixed to ensure that the correct mixture is
obtained.
Two-stroke oil
The fuel is petrol with a 2% oil mixture (one part oil
to 50 parts petrol).
For the best lubricating results use Atlas Copco’s
environmentally friendly two-stroke oil, which has
been specially developed for Atlas Copco’s petrol
engined hammering and rock-drilling machines.
If Atlas Copco’s two-stroke oil is not available, use
a high quality two-stroke oil for air-cooled engines
(not two-stroke oil for outboard engines). Contact
your local Atlas Copco representative for advice on
the correct two-stroke oil.
