of
operation
if
the
bolts have been disturbed for any
reason.

Liquid
Ballast
Filling the front and rear tires with liquid
ballast
is
a convenient method
of
adding weight
A solution
of
calcium chloride
ancfwaterJs
rec-
ommended. This gives a low

provides a higher density than plain water.
The table on the next page shows the quantity
of
calcium chloride and water
required.
for each tire
size option
and
is
based
on
0.6
kg
of calcium chlo-
ride 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
t.em-
perature
of-
46° C
(-
51° F).
Never add water to calcium chloride.
If
the flakes
should contact the
eyes,
wash the
eyes
immedi-
ately with clean, cold water for
at
least 5 minub:s.
Consult a doctor
as
soon
as
JX>Ssible.
NOTE:
Whenfilling a
tire
with
calcium
chloride/
water
solution
the
valve slwuld be
at
~
hi.ghest
point on
the
wheel.
The
valve should be at the low-
est
point when
checking
or adjusting air pressure
if
the
tire
contains
liquid ballast.
Special
equip-
ment
is
required
to
water ballast tires. See
yow
Ford
New
Holland dealer or tire supplier for de-
tails.
NOTE:
Front tractor tubes do not have air/water
valves fitted as standard
equipment.
A
suitable
air/water valve must be fitted
to
enable front tires
to be filled with calcium chloride
solution.
