TYRE CARE
Upon receiving your tractor, check the air pressure
in the tyres and recheck every 50 hours or weekly.
When checking tyre pressures, inspect the tyres for
damaged tread and side walls.
Inflation pressure affects the amount of weight that
a tyre may carry.
See the Tyre Pressure and Load tables, pages 3--144
and 3--145. Do not exceed the load for the pressures
listed. Do not over or under inflate the tyres. If the tyre
fitted to your tractor is not listed, consult your
authorised dealer for pressure and load information.
WARNING
Inflating or servicing tyres can be dangerous.
Whenever possible, trained personnel should be
called in to service or install tyres. In any event, to
avoid the possibility of serious or fatal injury, follow
the safety precautions below:
Never attempt tyre repairs on a public road or
•
highway.
Do not inflate a steering tyre (front tyre on a two
•
wheel drive tractor) above the manufacturer's
maximum pressure shown on the tyre or beyond
the maximum recommended by your authorised
dealer or tyre supplier.
Never inflate a traction tyre (front tyre on a four
•
wheel drive tractor or any rear tyre) over 2.8 bar
2
(40 lbf/in
). If the bead does not seat on the rim
by the time this pressure is reached, deflate the
tyre, relubricate the bead with a soap/water
solution and re-inflate. Do not use oil or grease.
Inflation beyond 2.8 bar with unseated beads
may break the bead or rim with explosive force
sufficient to cause a serious injury.
SECTION 3 - - FIELD OPERATION
After seating the beads, adjust inflation pressure
•
to the recommended operating pressure.
Do not re-inflate a tyre that has been run flat or
•
seriously under-inflated until it has been
inspected for damage by a qualified person.
Torque wheel to axle nuts to specification after
•
re-installing the wheel. Check nut tightness daily
until torque stabilises.
Refer to tractor weighting section before adding
•
ballast to the tyres.
Ensure the jack is placed on a firm, level surface.
•
Ensure the jack has adequate capacity to lift your
•
tractor.
Use jack stands or other suitable blocking to
•
support the tractor while repairing tyres.
Do not put any part of your body under the tractor
•
or start the engine while the tractor is on the jack.
Never hit a tyre or rim with a hammer.
•
Ensure the rim is clean and free of rust or
•
damage. Do not weld, braze, otherwise repair or
use a damaged rim.
Do not inflate a tyre unless the rim is mounted on
•
the tractor or is secured so that it will not move
if the tyre or rim should suddenly fail.
When fitting a new or repaired tyre, use a clip-on
•
valve adaptor with a remote gauge that allows
the operator to stand clear of the tyre while
inflating it. Use a safety cage, if available.
