Tyre Inflation Procedure
DONOTinflateatyrethathashadacompletelossofair.
Ifthetyrehaslostallairpressure,haveaqualifiedtyre
mechanicservicethetyre.
IMPORTANT: If the tyre wheel assembly has been removed
from the tractor always use a restraining device (tyre infla-
tion cage) when inflating a tyre.
To ADD air to a partly inflated tyre, use the following
procedure:
OPERATION1
UseaSAFETYTYPEairhosewitharemoteshutoffvalve
andaself-lockingairchuck.
OPERATION2
Stand behind the tread of the tyre and make sure all
personsareawayfromthesideofthetyrebeforeyou
starttoaddair.
OPERATION3
Inflatethetyretotherecommendedairpressure.DONOT
INFLATETHETYREMORETHANTHERECOMMENDED
PRESSURE.
Air Pressure Check
Checkthetyreinflationpressureevery50hoursofopera-
tionoronceperweek.
NOTE: For best tyre life check tyre pressures as regular
intervals. Too low a pressure causes early tyre wall failure.
Too high a pressure causes higher tread wear or dam-
age.
Checktheconditionofthetyresandwheelsforwearor
damage. Keep the tyres inflated to the recommended
pressures.
NOTE: Cross ply tyres can have the pressure reduced to
increase traction in field work. For speeds below 16 kph
(10 mph), loads can be increased by 20%.
NOTE: Never use radial ply tyres below 1.2 bar (17 psi). It
is not necessary to reduce the pressure in radial tyres to
get better traction in the field.
IMPORTANT: Before leaving the factory the tyre pressures
are increased. Check and adjust the pressures before
operating the tractor.
Fortyresequippedwithliquidballast,checktheairpres-
sureasfollows:
OPERATION1
Useanair-watergauge.Thevalvemustbeatthebottom
ofthetyretogetanaccuratereading.
OPERATION2
Useastandardairgaugeasfollows:
A. Thevalvemustbeatthetopofthetyre.
B. Measurethewheeldiameter.
C. Add3.5kPa(0.04bar-1/2psi)foreach305mm
(12inches)ofrimdiametertothestandardgauge
reading.
