INFLATING THE TIRES

Basic values of recommended inflation pressure are mentioned in the following
tables. Regularly check for the inflation pressure before operation. Check the
inflation pressure at cold tires. The tractor air pressure regulator can be used for tire
inflation. This regulator serves for maintaining the air pressure, filling tires and
serves as a safety valve. Remove the wing nut of regulator (or regulator rubber plug)
when inflating the tire and assemble a hose for tire inflating instead of it. Screw down
the hose fitting up to the end of thread for pushing the back pressure valve. In case
the maximal pressure 0,6 MPa (or 0,7 MPa at double hose brakes) is in air brake
tanks the tire can not be inflated. In this case it is necessary to reduce the pressure
by valve for draining the condensed water located in the bottom part of air tank. The
wing nut (or rubber plug) must be reassembled on the air pressure regulator after tire
inflating.
