Wheel ballasting by filling the tyres with fluid.
The driving wheels are ballasted by pouring water into the tyres.
Note: it is preferable to use tyres with inner tubes.
Note: if tubeless tyres are used, ask your dealer how to lubricate the disc correctly so as
to prevent it from rusting.
Note: use water with an antifreeze solution in cold weather (manufacturers recommend
neutral calcium chloride -CaCl
2
-).
How to pour in the water:
• position the valve at the top
• unscrew the mobile valve union
• pour in the water with a common water
hose
• stop filling every so often, so as to allow
the air to escape
• stop filling altogether when water spills
from the valve.
• the water should fill 75% of the tyre.
• tighten the mobile valve union.
• inflate the tyre to the normal operating
pressure.
How to drain out the water:
• position the valve at the bottom.
• unscrew the mobile valve union.
• allow the water to drain out.
• finish emptying the tyre by means of a
union with a pipe (draw pipe).
• inflate the tyre with air until all the water
has been drained out.
• tighten the mobile valve union.
• inflate the tyre to the normal operating
pressure.
