The quality and sulphur content of the diesel used must meet all the regulations concerning emissions applicable in the
region where the machine is used.
Only use diesel with an ultra-low sulphur content (maximum 0.0015% [15 mg/kg]).
Using biodiesel
Biodiesel may only be used if its properties meet the most recent version of EN14214 or similar specifications.
The current maximum permitted biodiesel concentration is a 5% mixture (also called B5) with normal petroleum diesel.
Concentrations up to B20 may be used if the machine is modified with the original Yanmar B20 kit (KIT-V384BGS-BI).
The use of B6-B20 fuel requires a different maintenance interval for some components and special procedures for fuel
transport and machine storage.
Ask your Roberine dealer if you wish to know whether the recommendations for the use of biodiesel have changed.
6.2 Testing the safety system
WARNING Avoid injury! The exhaust gases from the engine contain carbon monoxide and can cause serious
illness or even death.
• If possible, move the machine outdoors before starting the engine.
• Never run the engine in an enclosed space without sufficient ventilation. If there isn't sufficient ventilation,
connect an extension hose to the engine’s exhaust so that the exhaust gases are removed from the room.
• Allow fresh air to enter the workplace so that the exhaust gases are expelled.
The machine’s safety systems must be tested every time before the machine is used. Carefully read the machine’s
instruction manual and make sure you are familiar with how the machine works before testing the safety systems.
Use the following test procedures to check whether the machine works correctly.
Do not use the machine if a fault is discovered during one of these procedures. Ask your authorised Roberine dealer for
maintenance advice.
CAUTION! Perform the tests in an area without obstacles, keep a minimal clearance of 5 metres. Keep
bystanders away from the area.
