Checking the treads on the tires
Inspect the tire treads from time to time to
ensure no asphalt has stuck to the tires. This can
occur before the tires are sufficiently warm.
Mixing 2-4% cutting fluid to the tire sprinkler water
can prevent this problem.
Variable tire pressure (air-on-the-run) (Option)
The operator can vary the pressure while work is
in progress with the air pressure control on the
roller.
The pressure is variably by adjusting the keys
(fig1) on the keypad. Pressure adjusting interval is
between maximum 780kPa (110psi) and minimum
380kPa (55psi). Push the key to upward position
(1) to increase the pressure; push the key
downward (2) to reduce the pressure.
The pressure level of the tire is shown on the
pressure gauge on the top left corner of the
instrument board.
The tire pressure should not be lower than
380 kPa, otherwise it would impair the service life
of the tire.
