Tire Inflation Information
Tire Inflation
WARNING
Personal injury or death could result when tires
are inflated incorrectly.
Use a self - attaching inflation chuck and stand
behind the tread when inflating a tire.
Proper inflation equipment and training in using
the equipment are necessary to avoid
over-inflation. A tire blowout or rim failure can
result from improper or misused equipment.
NOTICE
Set the tire inflation equipment regulator at no more
than 140 kPa (20 psi) over the recommended tire
pressure.

Standard tire, ply rating and inflation pressures.
The operating 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 and should always be
obtained from your tire supplier.
NOTE:
Fill tires to the recommended pressures
listed ± 35 kPa (5 psi). Tires can be filled
with nitrogen.
Tire Inflation Pressures
Adjustment
Tire inflation in a warm shop area, 18° to 21°C (65°
to 70°F), will be underinflated if the machine works
in freezing temperatures. Low pressure shortens
the life of a tire.
