• When pumping up the tires, check that no other person is
standing near the tire, and install an air chuck with a clip
that can be secured to the air valve.
To prevent the tire inflation pressure from becoming too
high, measure the pressure from time to time with an air
gauge while pumping up the tire.
• If the tire inflation pressure goes down abnormally or the
rim parts do not fit the tire, there is a problem with the tire
or rim parts. Always contact your Komatsu distributor for
repairs.
• If the rim parts are not fitted properly when the tire is being
pumped up, there is a danger that the rim parts may fly off, so set up a protective fence around the tire, and
do not stand directly in front of the rim. Stand beside the tread when pumping up the tire.
• Do not adjust the tire inflation pressure immediately after traveling at high speed or operating under heavy
load.
• Never perform welding or light a fire near the tire.
• Always release the inflation pressure from a tire prior to removing rim from tire.
• Before removing the tire from the machine for repairs, remove the valve partially to release the air from the
tire gradually, then remove the tire.
PRECAUTIONS FOR STORING TIRES
Tires for construction equipment are extremely heavy, it may
lead to serious personal injury or death. To maintain safety, al-
ways observe the following.
• As a basic rule, store the tires in a warehouse which unau-
thorized persons cannot enter.
If the tires must be stored outside, always erect a fence
and put up “No Entry” signs.
• Stand the tire at the angle of 60 to 70 ° (A) on a level
ground, and block it securely (1) so that it cannot tip over
or fall over if any person should touch it. Do not lay the tire
on its side. This will deform the tire and cause it to deterio-
rate.
• If the tire should fall over, do not attempt to stop it. Get out of the way quickly.
