Safety and operating instructions

Transport

WARNING Fuel hazard
► Empty the tank before transport.

Installation

Fuel

Two-stroke oil

The fuel is petrol with a 2% oil mixture (1 part oil to
50 parts petrol). Always use high quality lead-free
petrol (non-alkylat).
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.

Mixing the petrol and oil

Always mix the petrol and oil in a clean petrol can.
First add the oil and then the correct amount of petrol.
Then shake the can thoroughly. Shake the can before
every refilling.
NOTICE During long term storage of two-stroke
mixture, the oil and petrol can separate. Never mix
more fuel than you intend to use within two weeks.

Filling

WARNING Fuel hazard
The fuel (petrol and oil) is extremely flammable and
petrol fumes can explode when ignited, causing
serious injury or death.
Protect your skin from contact with the fuel.
►
► Never remove the filler cap and do not fill the fuel
tank when the machine is hot.
Never smoke when filling the fuel tank or when
►
working with the machine or servicing it.
Avoid spilling fuel and wipe off any fuel spilled on
►
the machine.

Filling procedure
1. Stop the engine and let it cool down before filling
the tank.
2. The machine must be in a upright position when
filling it with fuel.
3. Release the filler cap slowly to let any pressure
escape.
4. Never overfill the tank. It is possible due to the
movement of the fuel within the tank to have fuel
at a higher level than the tank cap, which can
lead to a spillage of fuel if the tank cap is opened.
This can be avoided by opening the tank cap,
only when the machine is tilted and the tank cap
is at the fuel tanks highest point.
5. Make sure that the filler cap is screwed on when
the machine is used.
