MAINTENANCE

SELECT AND CHECK TIRES

k k
If a tire or a rim is handled improperly, the tire may burst or
may be damaged and the rim may be broken and scat-
tered, and that can cause serious injury or death.
• Since maintenance, disassembly, repair and assembly of
the tires and rims require special equipment and skill, be
sure to ask a tire repair shop to do the work.
• Never perform welding or light a fire near the tire.
TIRE SELECTION
Select the tires according to the conditions of use and the weight of the attachments on the machine.
