WARNING:

Secure the front and rear chassis with the
articulation stopper (lock bar and pins).

When inflating tires, stand behind the tread and
use the self-attaching chuck with a line extension.

Avoid welding near tires, which could potentially
cause the tires to explode.

A tire may explode if it is smoking due to intense
heat such as if the machine catches fire.

Never weld on rims. Replace defective rims.
IMPORTANT:

Always maintain the correct tire pressure.

Even if only one tread pattern has worn out,
replace the tire with new one. Tires must be
evenly sized. Before operating the machine,
check the tires for damage.

When replacing one tire, use a new tire having the
same tread pattern and specification as the other
tires.
Check Air Pressure
1. Measure air pressure when the tires are cool before
operating the machine.
