NOTE: The tires shown in the table above are for general outfit. Therefore, the tires fitted to your machine may vary
from those shown.
Liquid ballast
Filling the front and rear tires with liquid ballast is a con-
venient method of adding weight.
A solution of calcium chloride and water is recommended.
This gives a low freezing point and provides a higher den-
sity than plain water.
WARNING
Hazardous chemicals!
SLOWLY add calcium chloride flakes to water,
stirring continuously. To avoid a violent reac-
tion, NEVER add water to calcium chloride.
If any flakes contact the eyes, flush the eyes
immediately with clean, cold water for at least
15 minutes. Seek medical assistance immedi-
ately.
Failure to comply could result in death or se-
rious injury.
W0388A
NOTE: When filling a tire with calcium chloride/water solu-
tion, the valve should be at the highest point on the wheel.
The valve should instead be placed at the lowest point of
the wheel during the tire pressure check and adjustment.
The table above shows the quantity of calcium chloride
and water required for each tire size option (
0.6 kg ( 1 lb )
of calcium chloride per liter of water to give a 75% fill of
the tire).
This calcium chloride/water solution will give protection
from freezing down to an ambient temperature of
-46 °C
( -50.8 °F ).
