11.6.2 Assembling tyres
(workshop work)
WARNING
Danger to life caused by crushing and impact in
case of unprofessional or incorrect operation.
Instruct persons to leave the working and danger
zone when working on the machine!
NOTE
¾
Perform a wheel change only with profound
expert knowledge and by using proper as-
sembly tools.
¾
Work only on level ground with sufficient load
bearing capacity.
¾
Observe the accident prevention instructions
when changing the wheels.
¾
When assembling new tyres always use new
tubeless valves or tubes.
¾
Remove any corrosion found on the tyre
contact area of the rims before assembling a
new / different tyre.
¾
When travelling, traces of corrosion can cause
damage to the rims.
¾
Always screw valve caps with integrated seal
on the valves.
¾
Tighten the wheel screws with 510 Nm.
11.6.1 Air pressure in tyres
The required air pressure in the tyres
depends on:
•
Tyre size
•
Load bearing capacity of the tyres
•
Travel speed
The performance of tyres is reduced by:
•
Overloading
•
too low air pressure in tyres
•
too high air pressure in tyres
NOTE
Check the air pressure in the tyres regularly
before starting to drive, i.e. with cold tyres (see
chapter 1).
The difference in tyre pressure between the
tyres on one axle must not exceed 0.1 bar.
During fast travelling or hot ambient tempera-
tures the air pressure may rise by up to 1 bar.
Do not reduce the air pressure, because it may
then drop too low when cooling down!
