Tire inflation procedure
Do not inflate a tire that has had a complete loss of air. If the tire has lost all air pressure, have a qualified tire mechanic
service the tire.
To add air to a partly inflated tire, use the following procedure:
1. Use an air hose with a remote shutoff valve and a self-locking air chuck.
2. Stand behind the tread of the tire and make sure all persons are away from the side of the tire before you start to
add air.
3. Inflate the tire to the recommended air pressure. DO NOT inflate the tire more than the recommended pressure.
Tire inflation examples
For maximum sprayer performance, always adjust the tire
pressure to the recommended range to conform with the
actual load on the tires. Use the tire and load and inflation
charts to match the tire pressure to the machine weight.
This example shows the cross section of a tire inflated for
maximum load but with a minimum load on the tire. The
tire tread is not making full contact with the ground which
will give poor performance.
This example shows the cross section of a tire with the
inflated pressure correctly adjusted to the load on the tire.
The tire tread is making full contact with the ground which
will give maximum performance.
