B
Tire pressure
If the air pressure in the tire is too high or too low, the life
of the tire will be shortened. Make routine checks of the air
pressure in tires. Check the tires and rims for damage and
eliminate defects before starting operation.
C
Tire pressure
1. Insufficient tire pressure.
Too small an amount of air in the tire can cause it to
have excessive slack, which makes for faster wearing
down of the tread.
2. Correct tire pressure.
3. Excessively high tire pressure.
Too high a tire pressure causes the tractive force of
the machine to decrease, or the tire to slip. There is
also the risk of a blow out.
