The maximum pressure is 500 kPa (73 psi).Note: Operating the machine with an underinflated tire can lead to immediate tire failure or damage to the sidewall of the tire. Tire slippage on the rim may also result from an underinflated tire. The tires should be inflated to the maximum pressure when you are operating in rocky terrain or if you are using chains or tracks. When you are operating the machine in soft terrain, use the lower range of tire pressure.Note: If you are operating the machine on soft ground, use the lower range of the tire inflation pressures. If you are operating the machine on rocky terrain or chains are being used on the tires, use the upper range of the tire inflation pressures. The machines are shipped with the maximum tire pressure.The tire inflation pressure is based on the weight of a ready-to-work machine without attachments, at rated payload, and in average operating conditions. Pressures for each application may vary. Always obtain the proper pressures from your tire supplier.
