when lifting these tyres. If forklift trucks are used for
handling, they should be equipped with broad, well-
rounded arms to distribute the load and prevent
damage to the tyre bead. When handling tyres with the
fork truck do not scrape the fork across the bead.
Tubeless tyre rims perform an important function as
part of the assembly air seal. Proper care, therefore,
must be taken not to distort or mutilate the rim parts
because they must mate properly to form part of the
basic air chamber. Since the rim base and bead seat
band are mating surfaces, distortion may prevent easy
assembly as well as possibly resulting in no seal.
Never drop, tumble, or roll rim parts.
If rim parts are stored outdoors, they should be given a
protective coat of a good commercial primer.
Similar parts should be stacked neatly to prevent distortion.
Babbit or lead hammers, not sledge hammers, should
be used in assembling rim parts.
'O' rings are seals and should be carefully stored in a
cool, dry place where they will not be injured or
damaged.
Valve cores should also be stored in a cool, dry and
clean place.
MAINTENANCE
Check tyre pressures daily, preferably before the
machine is placed in operation. Refer to 'Tyre Inflation
Pressures' table.
Every 50 hours of operation (weekly), torque tighten
wheel rim nuts to 590 Nm (435 lbf ft).
Check tyres regularly and replace or repair if required.
SERVICE TOOLS
